B0022 on 2009-2014 Chevrolet Traverse: Airbag Light and Passenger Pretensioner Fault

What's Unique About the 2009-2014 Chevrolet TRAVERSE

The first-generation Chevrolet Traverse and its GM Lambda platform mates (GMC Acadia, Buick Enclave, Saturn Outlook) are known for issues with the Supplemental Restraint System (SRS) wiring located under the front seats. GM issued a major safety recall (NHTSA #14V118, GM #14030) for 1.18 million of these SUVs due to poor terminal crimps and corrosion in the under-seat connectors causing high resistance. A subsequent Special Coverage bulletin (#15536) was issued to correct faulty recall repairs. This extensive history means that for a Traverse, code B0022 is far more likely to be a simple wiring or connector issue than a failure of the actual pretensioner component, a fact supported by numerous owner complaints and official GM documents.

Symptoms You May Notice

• Airbag warning light is continuously illuminated on the dashboard.
• "SERVICE AIR BAG" message displayed on the Driver Information Center (DIC).

Most Likely Causes

1. Damaged or Loose Wiring Connector Under Passenger Seat 🔴 High Probability This is a known factory issue addressed by GM Safety Recall 14030 and Special Coverage 15536, which identified problems with corrosion and loose crimps in the under-seat connectors. Movement of the seat can also stress and damage the harness over time. GM Preliminary Information bulletin PI1357 also identifies high resistance from poor terminal crimps as a cause for B0022-0D or B0022-04.
   How to confirm: Visually inspect the large yellow connectors under the front passenger seat for signs of damage, corrosion, or looseness. A technician can check service history to see if the recall repair was performed. Using a scan tool to monitor the pretensioner circuit resistance while wiggling the connector can show fluctuating values, confirming a bad connection.
   Typical fix: The official GM fix per recall 14030 is to completely remove the connectors and permanently splice and solder the wires together. This eliminates the faulty connector as a future failure point.
   Est. part cost: $15-$60
2. Broken or Dislodged Connector Position Assurance (CPA) Retainer 🟡 Medium Probability GM TSB #08-09-41-002H covers intermittent SRS codes caused by faulty CPA retainers across many models, including the Traverse. These small plastic clips can become brittle and fail, allowing the main connector to back out slightly, which is enough to break the circuit and trigger the code.
   How to confirm: Inspect the yellow SRS connectors under the seat. The CPA is a small, often different-colored, plastic clip that locks the main connector halves together. If it's missing, broken, or not fully seated, this is the likely cause. A video shows that if the connector is not fully locked with the CPA, resistance will be out of spec. 🎬 Watch: How to diagnose and fix the B0022 wiring fault.
   Typical fix: Reseat the connector and install a new CPA retainer. The retainer itself is an inexpensive part, but may be hard to source individually. A forum member identified a potential part number for a package of these clips.
   Est. part cost: $5-$15
3. Failed Passenger Seat Belt Pretensioner Assembly ⚪ Low Probability
   How to confirm: This is diagnosed by exclusion. If the wiring, connector, and CPA are all confirmed to be in perfect condition (including having the recall solder repair performed), a technician can use a special diagnostic tool (a load resistor of about 2.2 ohms) to substitute the pretensioner. If the code disappears with the tool connected, the pretensioner itself has failed internally.
   Typical fix: Replace the entire passenger seat belt retractor/pretensioner assembly, which is located at the base of the B-pillar. This part contains the pyrotechnic charge and should only be handled by a qualified technician.
   Est. part cost: $250-$400

Rare But Worth Checking

• Failed Sensing and Diagnostic Module (SDM): This is extremely rare. The SDM is the airbag computer. It should only be considered after all other possibilities, including all wiring and components, have been professionally tested and ruled out.

Diagnosis Steps

1. Verify the airbag light is on and retrieve codes with an OBD-II scanner capable of reading SRS (B-codes) and their symptom bytes (e.g., B0022-0D). Confirm B0022 is present.
2. CRITICAL SAFETY STEP: Disconnect the negative battery terminal and wait at least 3-5 minutes (longer is safer) for the SRS system's backup power to discharge before proceeding.
3. Check the vehicle's service history using its VIN to see if Safety Recall 14030 / Special Coverage 15536 has been performed. This may be a free dealer repair.
4. Visually inspect the yellow wiring connectors under the passenger seat. Check for any signs of damage, stretched wires, or corrosion. An owner complaint to the NHTSA specifically mentions these connectors as the cause.
5. Inspect the Connector Position Assurance (CPA) retainer on the connector, as specified in TSB #08-09-41-002H. Ensure it is present, intact, and fully locked.
6. If a problem is found with the wiring or connector, and the recall has not been done, the official repair is to remove the connector and solder the wires as outlined in GM's service bulletins. Do not simply tape over a damaged wire.
7. If the recall was performed but the light is back on, the repair may have been done incorrectly and may be covered under Special Coverage 15536.
8. If no visible issues are found, the issue should be diagnosed by a professional using a dedicated SRS load tool to safely test the circuit without replacing parts unnecessarily.
9. After any repair, reconnect the battery and use a capable scan tool to clear the SRS codes. Cycle the ignition and check if the code returns.

Related Codes That Often Appear With This One

• B0015 — B0015 is the equivalent code for the Driver's side seat belt pretensioner. Since the under-seat wiring harnesses for both seats are of a similar design and subject to the same recall (14030), it's not uncommon to see faults on both sides.

Technical Service Bulletins (TSBs) & Recalls

• Bulletin #08-09-41-002H: Addresses intermittent airbag lights caused by faulty Connector Position Assurance (CPA) retainers, and lists B0022 as one of the affected codes.
• Bulletin #15536 (Special Coverage): Details the re-repair process for vehicles where the initial Recall 14030 (wiring splice) was performed incorrectly, causing codes like B0022 to return.
• Bulletin #PI1357: Specifically for 2014-2015 models, this bulletin notes that B0022 with symptom bytes 04 (open) or 0D (high resistance) can be caused by poor terminal crimps in the front seat connectors (X320, X332) and recommends soldering the female terminals.

Platform-Specific Known Issues

• NHTSA ODI #11303060: A 2014 Traverse owner reported the airbag indicator came on with code B0022, stating, "ALL OF THESE PROBLEMS APPEAR TO BE DUE TO ISSUES WITH THE CONNECTORS UNDERNEATH THE FRONT DRIVER AND PASSENGER SEATS."
• NHTSA ODI #10810786: An owner of a 2014 Traverse was told by the dealer that for code B0022, "GM TELLS THEM TO CHECK FOUR WIRES ON THE CONNECTORS TO THE FRONT PASSENGER SEAT WIRING HARNES…" and that the fix is to solder them.
• GM Special Coverage #15536: This bulletin addresses vehicles, including the 2009-2013 Traverse, where a previous recall repair for the side airbag wiring (Recall 14030) may have been done incorrectly, leading to recurring airbag faults like B0022. The fix involves re-doing the wire splice repair.

Mechanic-Grade Diagnostic Values

• Passenger Seat Belt Pretensioner Deployment Loop Resistance — expected: 1.1 to 3.9 ohms. Failure: A reading below 1.1 ohms sets B0022-0E; above 3.9 ohms sets B0022-0D. A very high reading like 25.5 ohms indicates an open circuit (B0022-04).
• Diagnostic Resistor for Pretensioner Simulation — expected: 2.2 to 2.7 ohms. Failure: This is a known-good resistor used as a diagnostic tool. If connecting this resistor in place of the pretensioner clears the code, the pretensioner itself is confirmed to be faulty.
• Sensing and Diagnostic Module (SDM) Operating Voltage — expected: 9 to 16 volts. Failure: Voltage outside this range can cause the SDM to malfunction and set various codes, including B0022.

Hidden / Shadow Codes Worth Checking

• B0022-01: Passenger Seat Belt Retractor Pretensioner Deployment Loop Short to Battery (see via Professional-grade scan tool (e.g., GM Tech2, GDS2, high-end Autel/Snap-on) capable of reading SRS module symptom codes.)
• B0022-02: Passenger Seat Belt Retractor Pretensioner Deployment Loop Short to Ground (see via Professional-grade scan tool (e.g., GM Tech2, GDS2, high-end Autel/Snap-on) capable of reading SRS module symptom codes.)
• B0022-04: Passenger Seat Belt Retractor Pretensioner Deployment Loop Open Circuit (see via Professional-grade scan tool (e.g., GM Tech2, GDS2, high-end Autel/Snap-on) capable of reading SRS module symptom codes.)
• B0022-0D: Passenger Seat Belt Retractor Pretensioner Deployment Loop Resistance Above Threshold (see via Professional-grade scan tool (e.g., GM Tech2, GDS2, high-end Autel/Snap-on) capable of reading SRS module symptom codes.)
• B0022-0E: Passenger Seat Belt Retractor Pretensioner Deployment Loop Resistance Below Threshold (see via Professional-grade scan tool (e.g., GM Tech2, GDS2, high-end Autel/Snap-on) capable of reading SRS module symptom codes.)

Scan Tool Commands That Help

• GM GDS2 / Tech2: Read SRS DTCs with Symptom Bytes — This is the first step to understand the specific nature of the B0022 fault (e.g., open circuit, high resistance, short to ground) which is critical for an accurate diagnosis.
• GM GDS2 / Tech2: View Live Data - Deployment Loop Resistance — To monitor the real-time resistance of the passenger pretensioner circuit. Wiggling the under-seat connector while watching this data can confirm a loose connection if the resistance values fluctuate wildly.
• GM GDS2 / Tech2: Clear SRS Codes — This is performed after a repair is completed to turn off the airbag light. The code will become a 'history' code if fixed, or remain 'current' if the fault persists.

Wiring & Ground Locations

• X320 / X332 — Under the front passenger seat, connecting the body harness to the seat harness.. This is the primary connector identified in GM recalls and bulletins as the source of high resistance, corrosion, and loose terminals that cause code B0022. Bulletin PI1357 specifically calls out these connectors.
• G302 — At the base of the right-hand (passenger side) B-pillar, under the trim.. This is a major body ground point for multiple components on the passenger side of the vehicle. While not directly part of the two-wire pretensioner loop, a poor ground here can cause widespread electrical issues and potentially affect SDM readings. A video diagnosing a 2015 Traverse with strange electrical problems traced the fault to this ground point.
• Shorting Bars — Inside the yellow SRS harness connectors.. When an SRS connector is disconnected, internal shorting bars automatically connect the two terminals together on the component side (e.g., the pretensioner). This is a safety feature to prevent static discharge from causing a deployment. However, it means you cannot accurately measure the resistance of the component through the disconnected harness; you must probe the component's pins directly.

Real Owner Repair Stories

• YouTube channel 'El Garage De Leonardo' (Unspecified GM vehicle) — Airbag light on with code B0022-0D (High Resistance).
  ❌ Tried (didn't work) A previous repair attempt involved cutting off the pretensioner and wiring in a resistor, but the connection to the resistor failed.
  ✅ What actually fixed it The technician re-soldered a 2.3 ohm resistor to the circuit wiring in place of the pretensioner. This satisfied the SDM's resistance requirement and allowed the code to be cleared, demonstrating a common (though not recommended for safety) bypass technique.
• YouTube channel 'Auto Repair Guys' (Chevrolet Cruze (demonstrates a common GM issue)) — Airbag light on, 'Service Airbag' message, code B0022-04 (Open Circuit) with a scan tool reading of 25.5 ohms.
  ❌ Tried (didn't work) The video focused on direct diagnosis rather than failed attempts.
  ✅ What actually fixed it The connector at the seat belt retractor was not fully seated. Pushing the connector in until the lock clicked caused the resistance to drop to a normal 2.2 ohms and allowed the code to be cleared. This highlights the importance of the CPA clip and a secure connection.
• NHTSA complaint leading to a dealer visit (2014 GMC Acadia (Lambda Platform sibling)) — "service air bag" light came on.
  ❌ Tried (didn't work) Initial dealer repair of a SIR module and sensor for $530 did not fix the problem; the light came on again immediately.
  ✅ What actually fixed it On the second visit, the dealer found a GM bulletin advising them to solder the electrical connections. This repair permanently solved the problem, confirming the factory wiring connection as the root cause.

OEM Part Supersession History

• N/A → 88988974 — This is the standard part number for the orange or gray Connector Position Assurance (CPA) retainer referenced in TSB #08-09-41-002H.
  Heads up: This part is widely used across many GM models from roughly 2005-2014 for various SIR system connectors.

Model Year Variations Within This Range

• 2014-2015: GM issued Preliminary Information bulletin PI1357 specifically for 2014-2015 Traverse, Acadia, and Enclave models for code B0022 (and others) with symptom bytes 04 or 0D. It identifies high resistance from terminal crimps in the front seat connectors (X333, X332, etc.) and recommends soldering the female terminals as the fix. This indicates the problem persisted even in the final years of the generation.
