Ultimate Guide to OBD-II Code B1067: A Manufacturer-Specific Fault (Nissan, Fiat, GM)

What Does B1067 Mean?

B1067 is a manufacturer-specific Body Control Module (BCM) code. For Nissan and Infiniti, it indicates a short circuit in the passenger-side 'assist' airbag module circuit. For Fiat and Alfa Romeo, it signifies an invalid signal from the electric power steering's torque or position sensor. For some GM vehicles, it points to a non-critical audio amplifier circuit fault.

Technical definition: The Society of Automotive Engineers (SAE) has not standardized this body code. The most common definition for Nissan/Infiniti is "Assist Air Bag Module Circuit Short". For Fiat/Alfa Romeo, it translates to "Steering Angle/Torque Sensor Invalid Signal" and is often logged alongside C1002. For GM models, it is defined as "Audio [+] output #5 circuit low".

Can I Drive With B1067?

No — Do Not Drive. Do not drive. If the code indicates an airbag fault (Nissan/Infiniti), the SRS system is disabled and airbags will not deploy in a crash. If it indicates a power steering fault (Fiat/Alfa Romeo), you risk a sudden, complete loss of steering assist, significantly increasing the risk of an accident.

Common Causes

• Low Battery Voltage or Bad Ground (Fiat/Alfa) (Very Common) — On Fiat/Alfa models, the electric power steering (EPS) system is a massive electrical load. A weak battery causes a voltage drop during engine cranking significant enough for the EPS module to shut down and log a fault. A corroded engine-to-body ground strap causes the exact same issue.
• Stored Crash Data (Nissan/Infiniti) (Very Common) — If the vehicle was in a minor accident, the SRS module stores 'crash data'. This permanently locks the module and illuminates the airbag light, even if no physical components are broken. This data requires a professional reset service to clear.
🎬 Watch: How crash data is cleared from an SRS module.
• Faulty Airbag Control Module (SRS/SDM) (Common) — The internal circuitry of the airbag control module fails from age, voltage spikes, or component degradation, incorrectly reporting a short circuit. This is the primary suspect after wiring and the airbag itself are ruled out.
• Damaged Wiring or Connectors (Common) — Wiring harnesses under seats or in the center console get damaged by moisture, corrosion, or physical stress from objects slid under the seat. A water bottle wedged against a yellow SRS connector frequently triggers this code.
• Faulty Passenger Airbag Assembly (Common) — The internal igniter (detonator) within the passenger airbag assembly develops an internal short circuit, which the main SRS control module detects 🎬 Watch: A professional walkthrough of Nissan airbag diagnostics. during its startup self-test.
• Faulty Clock Spring (Less Common) — The clock spring is a coiled conductor maintaining electrical contact for the steering wheel. A break or short here disrupts the SRS system and triggers various codes, occasionally including B1067 depending on the specific short path.
• Water Damage to Module or Wiring (Less Common) — The airbag module sits at a low point in the cabin (under the center console or seats), making it highly vulnerable to spilled drinks or water leaks from clogged sunroof drains.

Symptoms

• Airbag Warning Light On / Airbags Disabled (Nissan) — The SRS or airbag icon remains illuminated permanently. The control module enters a fail-safe mode, completely disabling the airbags and seatbelt pretensioners.
• Power Steering Warning Light On (Fiat/Alfa) — A red steering wheel icon illuminates on the dashboard, indicating a failure in the electric power assist system.
🎬 See how to handle Fiat power steering warning messages.
• Heavy, Erratic, or Asymmetrical Steering (Fiat/Alfa) — The steering becomes extremely difficult to turn, especially at low speeds. It may feel heavier or offer less assistance in one direction than the other, indicating the sensor is providing implausible data.
• Groaning or Vibrating Steering Column (Fiat/Alfa) — A groaning noise or vibration felt through the steering wheel when turning is a direct precursor to total failure of the torque position sensor within the steering column.

Used vs. New Parts: Buying Guide

When a used part is worth it: For a Fiat/Alfa steering column, a professionally reconditioned unit is the preferred option over a new dealer part. For a Nissan SRS module, resetting your original module is safer and cheaper than buying a used part that requires reprogramming.

Donor-vehicle mileage cap: roughly under 100000 miles for the part to have meaningful remaining life.

Donor quality checklist:

• For SRS modules, obtain a VIN history of the donor car to ensure it was not in a collision.
• For steering columns, favor reconditioned units from specialists who upgrade the known-failing torque sensor and offer a warranty.
• Match the part number exactly. Superseded numbers may not be compatible without dealership programming.

Decision logic:

• If Fault is stored crash data in a Nissan SRS module → Use a mail-in reset service on your original module. It is the cheapest, most reliable plug-and-play option.
• If Fault is a failed Fiat/Alfa steering column sensor → Buy a reconditioned column with a warranty. It provides the best balance of cost and reliability.
• If Part is a Nissan SRS module with an internal hardware fault → A used module from a reputable salvage yard is acceptable, but budget for dealership programming fees.

Warranty tradeoff: Used parts from salvage yards typically have a 30-90 day warranty. Reconditioned steering columns often come with a 1-year to lifetime warranty. New OEM parts carry a 1-year/12,000-mile warranty.

Worst-case if a used part fails: $300-$600 if a poorly reconditioned part fails, requiring repeat labor costs.

What Happens If You Wait — Timeline

1. Immediate (Nissan Airbag Fault): The moment code B1067 is set, the SRS light illuminates and the entire airbag and seatbelt pretensioner system is disabled. (MPG impact: 0%% · Added cost: $0 (The cost is the immediate and total loss of critical safety features).)
2. 0-3 Months (Fiat/Alfa EPS Fault - Intermittent): Steering assist fails intermittently, often on startup, and is corrected by restarting the engine. A groaning noise may be felt when turning. (MPG impact: 0%% · Added cost: $0-$150 for a potential battery replacement. The primary cost is the increasing risk of sudden failure.)
3. 3-6 Months (Fiat/Alfa EPS Fault - Frequent): Power steering failure becomes frequent and requires multiple restarts. Steering feels heavier in one direction. The fault is progressing to a hard sensor failure. (MPG impact: 1%% · Added cost: $400-$800. The torque sensor inside the column is failing permanently. A reconditioned column is required.)
4. 6+ Months (Fiat/Alfa EPS Fault - Permanent): Power steering assist is lost completely. The red steering warning light is on permanently. The vehicle is extremely difficult to steer at low speeds. (MPG impact: 2%% · Added cost: $500-$1200+. The cost of a reconditioned column plus labor. The risk of an at-fault accident is constant.)

Cost of Not Fixing It

• Immediate: For Nissan/Infiniti, the entire Supplemental Restraint System (SRS) is disabled. Airbags and seatbelt pretensioners will not deploy in an accident. (Added cost: Catastrophic injury costs in an accident that would have otherwise been minor.)
• Immediate: For Fiat/Alfa, a sudden, complete loss of power steering assist occurs. The vehicle becomes extremely difficult to steer, especially at low speeds or in an emergency. (Added cost: $500-$5,000+ in vehicle damage and liability from an at-fault collision due to loss of control.)

Diagnosis Steps

1. Confirm the Code's Meaning for Your Vehicle
   Use a high-quality OBD-II scanner capable of reading manufacturer-specific Body (B) codes. Confirm the exact definition for your make. A B1067 on a Nissan requires a completely different diagnostic path than on a Fiat.
   Tools: Advanced OBD-II Scanner (Beginner)
2. Check Battery Health & Grounds (Fiat/Alfa)
   Check battery voltage with the engine off (should be >12.4V) and running (14.0-14.5V). Pro Tip: To quickly diagnose a faulty engine ground strap, connect a jumper cable from the negative battery terminal to a solid metal part of the engine block. If the power steering fault disappears upon starting, replace the ground strap.
   Tools: Digital Multimeter, Jumper Cables (Beginner)
3. Visually Inspect Wiring and Connectors
   Disconnect the negative battery terminal and wait 15 minutes for the SRS backup power to discharge. Inspect the wiring for the relevant system (passenger airbag module for Nissan, steering column for Fiat). Look for loose connectors, chafed wires, or physical obstructions under the seats.
   Tools: Socket set, flashlight, trim removal tools (Intermediate)
4. Test the Passenger Airbag Circuit (Nissan)
   Unplug the passenger airbag assembly and plug a 2.2-ohm (1/4-watt) diagnostic resistor into the vehicle's wiring harness. This simulates a known-good airbag. If the B1067 code clears and does not return, the airbag assembly itself is faulty. If the code returns, the fault is in the wiring or the control module.
   Tools: 2.2 Ohm Resistor, Advanced OBD-II Scanner (Advanced)
5. Monitor Live Data PIDs (Fiat/Alfa)
   Using an advanced scan tool, monitor live data from the Electric Power Steering (EPS) module. Watch 'Steering Torque Sensor 1/2' and 'Steering Angle'. A value that is stuck, erratic, or does not change smoothly when the wheel is turned confirms a failed sensor inside the steering column.
   Tools: Advanced OBD-II Scanner with Live Data (Advanced)
6. Test Power and Ground at the Control Module
   Using a multimeter and a wiring diagram, test for proper power, ground, and communication signals at the connector for the SRS module (Nissan) or EPS module (Fiat). This confirms the module is receiving necessary inputs before condemning it.
   Tools: Digital multimeter, vehicle-specific wiring diagram (Advanced)
7. Bench Test Fiat Torque Sensor Signal
   If the steering column is removed, apply a low voltage source to the sensor's power and ground wires. Measure the voltage on the signal output wires with a multimeter. The voltage must change as torque is applied to the column. An incorrect or absent signal confirms a faulty sensor.
   Tools: Digital multimeter, variable DC power supply (Professional)
8. Replace or Repair the Faulty Component
   Replace the identified faulty component (wiring, clock spring, reconditioned steering column, or reset airbag module). Clear all codes. For steering components, perform a mandatory steering angle sensor calibration.
   Tools: Professional diagnostic and repair tools (Professional)

When This Code Triggers (Freeze-Frame Conditions)

• System State: Key-On Self-Test (The SRS or EPS module runs a self-check immediately after the ignition is turned ON. Hard faults are detected before the engine starts.)
• Battery Voltage: 9.5V - 11.5V (During Crank) (For Fiat/Alfa power steering faults, the code sets during engine cranking when a weak battery causes system voltage to drop below the module's operating threshold.)
• Steering Wheel Angle/Speed: Variable, low speed (On Fiat/Alfa models, the fault triggers during low-speed parking maneuvers when turning lock-to-lock places maximum demand on the torque sensor and EPS motor.)

Related Codes

• C1002 — On Fiat/Alfa models, C1002 ('Steering Column Motor Torque Sensor') is the root cause code that appears with B1067. C1002 confirms the sensor itself has failed.
• B1065 — On Nissan vehicles, B1065 indicates an 'Open Circuit' in the passenger airbag module, while B1067 indicates a 'Short Circuit'.
• B0053 — B0053 is a general SAE code for a fault in the 'Passenger Deployment Loop'. B1067 provides the more precise manufacturer diagnostic direction.

Climate & Environmental Factors

• Cold Weather: Significantly impacts Fiat/Alfa vehicles. Low temperatures reduce a battery's cranking power, causing a voltage drop that triggers a fault in the sensitive Electric Power Steering (EPS) module.
• Humidity / Moisture: Moisture accelerates corrosion on wiring harnesses and connector pins, including those for the SRS module (Nissan) or EPS module (Fiat). A corroded connector causes a short circuit, directly triggering code B1067.

How to Talk to a Mechanic About This Code

Say this: "I have a [Make/Model] with code B1067. For my car, this indicates a [airbag system/power steering] fault. I'd like to schedule a diagnostic appointment. If it's a Fiat/Alfa, please start by load-testing the battery and checking the engine ground strap before diagnosing the steering column. If it's a Nissan, please check for recalls and focus on diagnosing the SRS circuit."

This tells the shop you've done your research, specifies the correct system to diagnose, and directs them toward common, inexpensive root causes, preventing them from jumping to the most expensive conclusion.

Avoid saying:

• 'My airbag/steering light is on, can you fix it?' (Too vague, invites an expensive diagnostic process).
• 'Just do whatever it takes to fix it.' (Gives the shop a blank check).
• 'A friend told me it's the...' (Undermines your credibility).

Questions to ask before authorizing the repair:

• Can you provide a detailed, written estimate including parts, labor, and taxes?
• For a Nissan: If the SRS module has crash data, is a reset service an option instead of full replacement?
• For a Fiat: What were the results of the battery load test? If the steering column is the issue, are you using a new OEM or a reconditioned part, and what is the warranty?
• Will any post-repair calibration, like for the steering angle sensor, be required and is it included in the cost?

Where to Take It: Dealer vs Independent vs Chain

• Dealer: A safe but expensive choice. Best if the repair requires proprietary software or is covered by a warranty or recall.
  Best for: Vehicles under warranty., Confirmed need for module programming/re-flashing., Checking for and performing safety recalls.
  Downsides: Significantly higher labor rates and parts costs., More likely to recommend expensive wholesale replacement over affordable repairs (e.g., reset service/reconditioned part). (Typical cost: +50% vs. baseline)
• Independent Shop: Best fit for most out-of-warranty scenarios. A good independent shop specializing in European cars will be familiar with the common Fiat battery/ground issues and have sources for reconditioned columns.
  Best for: Out-of-warranty vehicles where cost is a major factor., Shops specializing in your vehicle's make (e.g., European or Japanese specialists)., Cost-effective solutions like using reconditioned parts or mail-in reset services.
  Downsides: Quality and expertise vary widely; vetting is crucial., May lack the very latest manufacturer-specific diagnostic tools for complex programming. (Typical cost: +0% vs. baseline)
• Chain Shop: AVOID. This is a safety-critical, specialized repair that is beyond the scope of most chain shops. They are unlikely to diagnose it correctly.
  Best for: Simple, routine maintenance like oil changes or tires.
  Downsides: Technicians often lack specialized training in complex SRS and EPS diagnostics., May not have scanners capable of reading manufacturer-specific 'B' or 'C' codes. (Typical cost: -10% vs. baseline)

When to Walk Away From the Repair

If the total estimated repair cost exceeds 50% of your car's current private-party market value, seriously consider selling or trading in the vehicle as-is.

• Car worth $3500, fix is $2200: Walk away. The repair cost is over 60% of the car's value. The money is better put toward a replacement vehicle.
• Car worth $8000, fix is $1200: Fix it. The repair cost is only 15% of the vehicle's value and resolves a critical safety issue.
• Car worth $4000, fix is $250: Fix it immediately. If the fix is a cheap one like a battery on a Fiat or an SRS module reset on a Nissan, it's a small investment to restore a major safety function.

What Scan Tool You Need for This Code

Minimum: A scanner that can read and clear manufacturer-specific codes from the SRS (Airbag) and/or EPS (Electronic Power Steering) modules. For Fiat/Alfa diagnosis, live data streaming for steering angle and torque sensors is highly recommended.

A cheap, generic $20 OBD-II code reader will NOT work. It can only read engine and emissions ('P') codes. It cannot see or clear Body ('B') codes like B1067, and will report 'No Codes Found'.

Budget: Autel AutoLink AL619 or Foxwell NT630 Plus (~$80-120) — These are entry-level handhelds specifically designed to read and clear codes from the Engine, ABS, and SRS (Airbag) systems. They are the minimum viable tool for the Nissan fault.

Mid-range: Foxwell NT510 Elite or Autel MaxiCOM MK808 (~$180-450) — Provides full-system diagnostics, including SRS and EPS. Crucially, they offer live data streaming to watch the Fiat's steering sensor values in real-time. Some offer bidirectional controls for steering angle sensor calibration.

Professional: Autel MaxiSys Series or Launch X431 Series (~$500-1500) — Offers full bidirectional control to test components, perform advanced calibrations (like SAS reset), and potentially code new modules. These are professional-grade tools.

Rent vs buy: Rent first. Many auto parts stores offer a loaner tool program where you can borrow a more advanced scanner capable of reading SRS/ABS codes for free with a refundable deposit.

How to Clear the Code After You Fix It

1. Reconnect the negative battery terminal.
2. Use a manufacturer-specific OBD-II scan tool to clear codes from the SRS or EPS module.
3. For Fiat/Alfa steering repairs, perform a Steering Angle Sensor (SAS) calibration using the scan tool.
4. For Nissan SRS faults, verify the airbag light turns off after the initial 7-second self-check.

Drive cycle (~15 minutes): A specific drive cycle is not required for SRS or EPS systems. After clearing the code, a 15-minute test drive with several lock-to-lock turns confirms the repair and SAS calibration.

Readiness monitors affected: Not applicable. Readiness monitors relate to emissions, not SRS or EPS.

Watch out for:

• Using a generic $20 OBD-II scanner will not clear Body (B) codes.
• Forgetting to perform the Steering Angle Sensor calibration after a Fiat/Alfa steering column replacement causes the code to return immediately.
• Attempting to clear stored 'crash data' on a Nissan with a scanner; it requires a professional EEPROM reset service.

Will This Fail Emissions / State Inspection?

Yes — this code typically fails an OBD-II emissions inspection.

• California: An illuminated airbag warning light is an automatic failure of the state's safety inspection, blocking registration renewal.
• New York: NYS vehicle inspection explicitly checks for an illuminated airbag warning light. The vehicle will fail the safety inspection.
• Texas: Many inspection stations will fail a vehicle for any illuminated safety warning light as a matter of policy.

Most Commonly Affected Vehicles

• Nissan Sentra, Altima, Rogue, Qashqai (2000-2019) — Indicates a short in the passenger assist airbag module. The 2013 Sentra and 2006-2012 Qashqai are highly affected models.
• Infiniti Various Models (2000-2019) — Shares SRS components and code definitions with Nissan, pointing to a passenger airbag circuit fault.
• Fiat 500, Punto, Panda, Argo (1999-2021) — B1067 almost always indicates a fault with the electric power steering's torque/position sensor, especially on the Fiat 500.
• Alfa Romeo Mito (2008-2018) — Associated with a failure of the electric power steering sensor, causing loss of steering assist. Often logged with code C1002.
• Ford Ka (European) (2008-2016) — Shares a platform with the Fiat 500 and logs B1067 for the exact same power steering sensor fault.
• Chevrolet / Cadillac Tahoe, Suburban, Escalade (2000-2014) — On GM vehicles, B1067 refers to a non-safety fault: 'Audio [+] output #5 circuit low'. It does not illuminate the airbag light.

Manufacturer-Specific Notes

• Nissan / Infiniti: Diagnosis focuses strictly on the passenger airbag, under-seat wiring, and the SRS module. After any collision, the module requires a professional reset service to clear stored crash data.
• Fiat / Alfa Romeo: Before condemning the $1,000+ steering column, ALWAYS check the battery and main ground connections. A weak battery in cold weather is the most common trigger for this code.
• General Motors (GM): B1067 is documented as a minor audio circuit fault completely unrelated to safety systems. Verify the code definition with a GM-capable scanner before assuming an airbag issue.

Real Owner Stories

2009 Fiat Panda with intermittent power steering failure

Power steering randomly cut out during low-speed turns with lights and fan on. The red steering wheel light illuminated. Restarting the car temporarily fixed it. Scan tool showed codes C1002 and B1067.

What they tried:

1. Initially suspected the steering column/torque sensor was failing.
2. Noticed the car had been sitting for weeks and the fault was more frequent at first.
3. After several hundred miles of driving (charging the battery), the fault stopped recurring.

Outcome: The root cause was a weak battery causing a voltage drop under load, triggering the EPS fault. Ensuring the battery was fully charged resolved the symptoms permanently.

Lesson: On a Fiat/Alfa with power steering faults, always test the battery and alternator before assuming the expensive steering column is bad.

Nissan Sentra with persistent B1067 airbag light

Airbag light came on and would not clear. The code definition pointed to a short in the passenger airbag circuit.

What they tried:

1. Checked wiring under the passenger seat for damage; none found.
2. Used a 2.2-ohm resistor to bypass the passenger airbag assembly. The B1067 code still would not clear, ruling out the airbag itself.
3. Replaced the clock spring, but the code remained.

Outcome: The fault was traced to an internal failure within the main SRS Airbag Control Module. Replacing the module with a used unit and programming it turned off the light.

Lesson: Systematic diagnosis is key. Using a $2 dummy resistor saves hundreds by confirming if the airbag assembly is good or bad before replacing expensive modules.

Nissan Pickup with B1067 after a minor accident

Vehicle was in a minor front-end collision. No airbags deployed, but the SRS light came on and code B1067 was stored.

What they tried:

1. Repaired all physical damage from the accident.
2. Attempted to clear the B1067 code with a professional scan tool, but it returned immediately.

Outcome: The SRS module had stored 'crash data', which cannot be erased by a scanner. The owner sent the module to a mail-in reset service for $60. After reinstalling, the code was gone.

Lesson: If B1067 appears after any accident, the module has locked itself. A reset service is far cheaper than buying a new module from the dealer.

How to Prevent This Code From Triggering

• Maintain Battery Health (Every 6 months) — For Fiat/Alfa EPS systems, a fully charged battery is critical. Clean terminals of corrosion. A weak battery is the #1 cause of false EPS faults.
• Protect Electrical Connectors (During any related service) — Apply a small amount of dielectric grease to connector seals. This blocks moisture and prevents the corrosion that leads to short circuits in SRS and EPS systems.
• Inspect for Water Leaks (Annually (before rainy season)) — Check that sunroof drains are clear. Water leaking into the cabin pools around low-mounted electronics like the SRS module, causing corrosion and failure.
• Avoid Extreme Steering at Standstill (Fiat/Alfa) (Daily habit) — Holding the steering wheel at full lock while stationary puts maximum strain on the EPS motor and components. Reducing this habit prolongs the life of the steering column.
• Be Mindful of Under-Seat Obstructions (Nissan) (Weekly / During cleaning) — Ensure no water bottles or umbrellas roll under the front seats and impact the sensitive yellow SRS wiring harness, which causes shorts or disconnections.

Frequently Asked Questions

Can I reset the airbag light myself to fix code B1067?

If the code stems from a hard fault or stored crash data, the light will return immediately after clearing. Standard scanners cannot clear crash data. You must use a professional module reset service to clear the EEPROM.

Why does my scanner say B1067 is a power steering problem?

Your vehicle is likely a Fiat, Alfa Romeo, Lancia, or European Ford. On these cars, B1067 correctly identifies a fault in the electric power steering system. Focus your diagnosis on the battery, grounds, and steering column sensor.

Is it safe to drive with code B1067?

No. If the code relates to the airbag system, your airbags are disabled and will not deploy in a crash. If it relates to power steering, you risk a sudden loss of steering assist, making the car extremely difficult to control.

Can a weak battery cause code B1067?

Yes, specifically on Fiat and Alfa Romeo vehicles. The electric power steering motor draws massive current, and a weak battery causes a voltage drop during startup that triggers a steering module fault. Always test the battery before replacing expensive steering components.

What is an airbag module reset?

A reset service electronically reprograms the module's internal memory to erase permanently stored crash data after an accident. This unlocks the module so it functions normally again. It is a $50-$100 alternative to buying a brand new $800+ module.

My car was in a minor accident and now has this code. What does that mean?

Even if airbags didn't deploy, the impact caused the SRS module to store crash data and lock the system. A standard OBD-II scanner cannot clear this data. You must have the module professionally reset or replaced.

My Chevy has code B1067 but no airbag light. What's wrong?

On many GM vehicles, B1067 is not a safety-related code and instead indicates a minor fault in an audio amplifier circuit. Verify the exact definition for your specific year and model using a GM-capable scanner. You can likely ignore it if the audio works fine.

What is the most common misdiagnosis for B1067?

For Fiat/Alfa vehicles, mechanics often replace the $1,000 steering column without checking for a weak battery or bad ground strap first. For Nissan, people replace the airbag module before checking the under-seat wiring for simple shorts.

Why can't I find one single definition for B1067?

While the SAE standardizes Powertrain ('P') codes, automakers assign their own definitions to Body ('B') codes. B1067 is a prime example of a code that changes entirely depending on the brand.

Key Takeaways

• Confirm your vehicle's specific B1067 definition immediately: it means a disabled airbag on Nissan/Infiniti, a failing power steering sensor on Fiat/Alfa Romeo, or a minor audio fault on GM.
• Do not drive Nissan or Fiat vehicles with this code, as you face a 100% loss of airbag deployment or a sudden, total loss of power steering assist.
• For Fiat and Alfa Romeo models, test the battery and engine ground strap before replacing the $1,000+ steering column, as a voltage drop below 12V during cranking frequently triggers this code.
• If a Nissan logs B1067 after any collision, the SRS module has locked due to stored crash data; use a $50-$100 mail-in reset service instead of buying an $800+ new module.
