C1711 on 2014-2015 Infiniti Q70: TPMS 'No Data' Causes and Fixes

What's Unique About the 2014-2015 Infiniti Q70

For this generation of Infiniti, the manufacturer issued a specific Technical Service Bulletin (ITB13039A) acknowledging that C1711 and related 'No Data' codes can be caused by radio frequency (RF) interference. The TSB explicitly warns that aftermarket devices like 'smart cell phone chargers' or 'aftermarket DVD players' plugged into the 12V outlets can emit signals that block the TPMS sensor's 315MHz transmission. This makes it a unique and critical diagnostic step to check before assuming the sensor has failed.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• TPMS warning light flashes for approximately one minute at startup, then stays on solid.
• Tire pressure reading for the rear left tire is missing from the vehicle's information display (shows as "--").
• A 'Tire Pressure System Malfunction' message may appear on the information display.

Most Likely Causes

1. Failed TPMS Sensor (Dead Battery) 🔴 High Probability The internal, non-rechargeable batteries in TPMS sensors have a finite lifespan of 5-10 years. For vehicles in this year range, the original sensors are at or near the end of their expected service life, making battery failure the most common cause.
   How to confirm: Use a TPMS activation tool to attempt to read the sensor. If the tool cannot get a response (no pressure, temperature, or battery status), the sensor has failed and is no longer transmitting.
   Typical fix: Replace the TPMS sensor in the rear left wheel and register the new sensor ID to the vehicle's BCM using a TPMS OBD-II tool.
   Est. part cost: $40-$115
2. Radio Frequency (RF) Interference 🟡 Medium Probability Infiniti TSB #ITB13039A specifically identifies RF interference as a potential cause for this code on this platform. The bulletin explicitly calls out 'Cell phone chargers' and 'aftermarket DVD players' as common sources of interference that can trigger a C1711 code.
   How to confirm: Unplug all aftermarket 12V accessories (phone chargers, dash cams, power inverters, etc.). Clear the code (if possible) or turn the car off and on, then drive the vehicle above 25 mph for several minutes to see if the code stays away and the light turns off.
   Typical fix: Identify and remove the electronic device causing the interference. No parts replacement is needed.
   Est. part cost: $0
3. Improper Sensor Registration ⚪ Low Probability This typically only occurs after a new sensor has been installed or if tires have been rotated without performing the proper relearn procedure. Unlike some vehicles, this platform requires a specific OBD-II tool to write new sensor IDs; it cannot learn them automatically. 🎬 See how to program and register new Infiniti sensors
   How to confirm: Use a TPMS scan tool to check the sensor IDs registered in the BCM. If the ID for the rear left wheel does not match the sensor that is physically there, this is the cause.
   Typical fix: Use a TPMS tool to perform the OBD-II relearn/registration procedure, writing the correct sensor ID to the BCM.
   Est. part cost: $0 (labor cost only)

Rare But Worth Checking

• Faulty TPMS Control Module (Receiver/Antenna): This is very uncommon. It should only be considered if a new, known-good sensor cannot be registered and RF interference has been ruled out. This failure often presents with multiple TPMS 'No Data' codes (e.g., C1708, C1709, C1710, and C1711) simultaneously. A user on MyG37.com fixed this exact issue by replacing the TPMS receiver, P/N 40740-1NC2A, which is located behind the glove box 🎬 Watch: Troubleshooting a faulty TPMS module that won't reset on the related G37 model.

Diagnosis Steps

1. Verify the code with an OBD-II scanner capable of reading Chassis (C) codes.
2. Check the vehicle's information display to confirm the rear left tire pressure reading is blank (showing "--").
3. Unplug all aftermarket accessories from 12V power outlets to rule out Radio Frequency (RF) interference, as noted in TSB ITB13039A. Specifically check for phone chargers and dash cams.
4. Clear the codes and drive the vehicle for 5-10 minutes at speeds above 25 MPH. Most Infiniti systems reset automatically after driving if the fault is cleared. If the light does not return, an accessory was the cause.
5. If the code returns, use a TPMS activation tool at the rear left wheel to check if the sensor is transmitting. If the tool gets no reading (no ID, pressure, or temp), the sensor has failed.
6. If the sensor is transmitting but the code persists, the sensor's ID may not be correctly registered in the BCM. Attempt to re-register the sensor ID.
7. If a new sensor is installed, it is mandatory to register its new, unique ID to the BCM using a TPMS tool with OBD-II relearn capability.

Parts You'll Likely Need

Related Codes That Often Appear With This One

• C1708 — This is the code for the Front-Left wheel sensor. Seeing them together may indicate multiple sensors are failing from age, or a wider system issue like RF interference or a faulty TPMS receiver.
• C1710 — This is the code for the Rear-Right wheel sensor. If both rear sensors fail at once, RF interference or a receiver issue becomes more likely.

Technical Service Bulletins (TSBs) & Recalls

• ITB13039A: Discusses radio frequency interference from accessories causing 'No Data' TPMS codes (C1708, C1709, C1710, C1711) and provides general TPMS diagnostic information for all Infiniti vehicles.
• ITB15-025a: Warns that TPMS sensor damage during tire mounting/dismounting is not covered under warranty and requires special care and equipment.

Platform-Specific Known Issues

• As documented in TSB ITB13039A, this vehicle is susceptible to radio frequency interference from aftermarket electronics like 'smart cell phone chargers', which can mimic the symptoms of a failed sensor.
• This platform does not feature a manual TPMS reset button. The system is designed to reset automatically by driving at speeds over 25 mph for several minutes once the underlying fault is corrected.

Mechanic-Grade Diagnostic Values

• TPMS Sensor Battery Status — expected: OK / Normal. Failure: A 'Low' or 'N/A' reading from a TPMS diagnostic tool indicates the sensor's internal battery is depleted and the sensor needs replacement.
• BCM Power Supply Voltage (at connector M66, pin 38) — expected: Battery Voltage with Ignition ON. Failure: 0V indicates a loss of power to the BCM, which controls the TPMS. Check fuses and wiring.

Scan Tool Commands That Help

• Infiniti CONSULT-III / CONSULT-III Plus: ID REGIST (Work Support) — This is the dealer-level function required to register the unique ID of a new TPMS sensor to the BCM after replacement. The tool guides the technician to each wheel to read and write the new sensor ID.
• Infiniti CONSULT-III / CONSULT-III Plus: READ CONFIGURATION / WRITE CONFIGURATION — This function is used when the entire Body Control Module (BCM) is replaced. The vehicle's specific configuration must be read from the old BCM and written to the new one to ensure all systems, including TPMS, function correctly.

Wiring & Ground Locations

• TPMS Control Module (Receiver) — Located behind the glove box assembly. The glove box must be removed to access it. On the related G37 platform, it is a small black box with a single white electrical connector.. This is the central antenna that receives the signals from all four wheel sensors. While failure is rare, a fault here can cause multiple TPMS codes (C1708, C1709, C1710, C1711) to appear at once.
• Body Control Module (BCM) — Located in the passenger side footwell, typically to the right of the glove box area, behind trim panels.. The BCM is the main computer that processes the signals from the TPMS receiver and communicates with the rest of the vehicle. A power, ground, or internal fault in the BCM can cause TPMS issues, though this is rare.
• BCM Ground (M119) — This is a primary ground point for the BCM. Its exact location requires a factory service manual diagram, but it is in the vicinity of the BCM in the passenger cabin.. A poor ground connection at this point can cause a host of difficult-to-diagnose electronic issues, including malfunctions in systems controlled by the BCM like the TPMS.

OEM Part Supersession History

• 40700-1LA0A, 40700-1LA0B, 40700-1LA0C, 40700-1LA0D → 40700-1LA0E — Standard part revisions by the manufacturer for improvements or supplier changes.
  Heads up: These part numbers are generally interchangeable. However, when using aftermarket programmable sensors (like Autel), ensure the sensor is programmed for the specific Infiniti Q70 model year, not just the part number, to ensure correct communication protocol.
