C1708 on 2014-2015 Infiniti QX60: TPMS 'No Data' Causes and Fixes

What's Unique About the 2014-2015 Infiniti QX60

The 2014-2015 Infiniti QX60 is specifically mentioned in a Technical Service Bulletin (TSB ITB13039A) for being susceptible to radio frequency (RF) interference that can trigger TPMS codes like C1708. This interference often originates from low-quality aftermarket devices such as phone chargers or dash cams plugged into the 12V power outlets. The RF noise generated by these cheap electronics can overwhelm the 315 MHz signal from the TPMS sensor, causing the vehicle to think the sensor has failed. This makes it crucial to perform a simple check by unplugging these devices before assuming any parts are faulty.

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 and then stays on.
• "TPMS error: See owner's manual" or "Check Tire Pressure" message in the vehicle information display.
• Inability to see the pressure reading for one specific tire in the information display (it may show dashes "--").

Most Likely Causes

1. Dead TPMS Sensor Battery 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor TPMS sensors use sealed, non-replaceable batteries with a finite lifespan of 5-10 years. Vehicles from the 2014-2015 model years are now at an age where battery failure is the most common cause of sensor failure.
   How to confirm: Use a TPMS activation tool (e.g., Autel, ATEQ) to try and 'wake up' the sensor. If the tool receives no response or shows a low battery status, the sensor is almost certainly dead.
   Typical fix: Replace the faulty TPMS sensor. It is often recommended to replace all four sensors at the same time if they are original, as the others are likely to fail soon. 🎬 See this expert discussion on Infiniti and Nissan TPMS sensors.

2. Radio Frequency (RF) Interference 🟡 Medium Probability As documented in Infiniti TSB #ITB13039A, this vehicle platform is known to be sensitive to RF interference from aftermarket accessories (especially cheap, unshielded phone chargers, dash cams, or even game console chargers) plugged into the 12V power outlets.
   How to confirm: Unplug ALL aftermarket electronic devices from the vehicle's power ports. Clear the codes and drive for 10-15 minutes above 16 MPH. If the code does not return, one of the devices was the cause.
   Typical fix: Remove or replace the interfering electronic device with a higher-quality, well-shielded alternative. This is a zero-cost diagnostic step that should be performed first.
   Est. part cost: $0
3. Damaged TPMS Sensor ⚪ Low Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor Sensors can be damaged during tire mounting or dismounting if the technician is not careful. The sensor body is plastic and can be broken by the tire bead or tools.
   How to confirm: A visual inspection during a tire change may reveal physical damage. The sensor will also fail to respond to a TPMS activation tool.
   Typical fix: Replace the damaged TPMS sensor.

Rare But Worth Checking

• Faulty TPMS Receiver or Body Control Module (BCM): → Shop Body Control Module This is rare but should be considered if all four TPMS sensors are throwing 'No Data' codes (C1708, C1709, C1710, C1711) simultaneously, or if replacing a known-bad sensor does not resolve the issue for a single wheel. Diagnosis would require advanced tools like Infiniti's CONSULT-III plus.

Diagnosis Steps

1. Verify the symptom: Confirm the TPMS light flashes for about a minute on startup, then stays solid.
2. Read Codes: Use an OBD-II scanner capable of reading chassis (C-prefix) codes to confirm C1708 is present in the BCM.
3. Eliminate RF Interference: Unplug ALL aftermarket accessories (phone chargers, dash cams, etc.) from the 12V power outlets. This is a critical first step per TSB ITB13039A.
4. Test Drive: Clear the codes and drive the vehicle for 10-15 minutes above 16 MPH to see if the light and code return.
5. Scan Sensor: If the code returns, use a TPMS diagnostic tool at each wheel to attempt to read the sensor's ID, pressure, and battery status. The wheel that does not respond is the location of the faulty sensor.
6. Inspect and Replace: If a sensor is confirmed to be faulty, dismount the tire and replace the sensor. It is good practice to also replace the valve stem service kit.
7. Register New Sensor: Use a TPMS tool to perform the relearn procedure. This involves activating each sensor in sequence (LF, RF, RR, LR) and then using the tool's OBD-II function to write the new sensor IDs to the vehicle's BCM.

Parts You'll Likely Need

• TPMS Sensor (OEM #40700-3JA0B (supersedes 40700-3JA0A, may also be replaced by 40700-3JA0E)) — This is the component that fails, usually due to its internal battery expiring. The entire unit must be replaced. It operates at 315 MHz.
  Trusted brands: Infiniti (OEM), Schrader, VDO, Denso, Dorman, Continental, Autel
  OEM price range: $65-$100
  Aftermarket price range: $40-$75

Related Codes That Often Appear With This One

• C1709, C1710, C1711 — These are the codes for the other three wheels (FR, RR, RL respectively). If multiple or all of these codes appear together, it points towards a systemic issue like widespread RF interference or a faulty central TPMS receiver, rather than multiple sensors failing at once.

Technical Service Bulletins (TSBs) & Recalls

• ITB13039A: Low Tire Pressure Warning System (LTPWS) Information, which details how radio frequency interference can cause a 'No Data' condition (C1708, C1709, C1710, C1711).
• NTB13-088a: The Nissan-branded version of the same TSB, applicable to the platform-mate Nissan Pathfinder.

Platform-Specific Known Issues

• Infiniti Technical Service Bulletin ITB13039A directly addresses codes C1708, C1709, C1710, and C1711. It warns that radio frequency interference from aftermarket devices plugged into power outlets can cause a 'No Data' condition and should be investigated before replacing parts.
• The platform mate, the Nissan Pathfinder, has an identical TSB (NTB13-088a) for the same issue, confirming this is a platform-wide sensitivity.

Mechanic-Grade Diagnostic Values

• Body Control Module (BCM) Power Supply Voltage — expected: Battery voltage (approximately 12V) with ignition ON.. Failure: Voltage significantly below 12V or 0V indicates a problem with the BCM's power supply circuit or a blown fuse.
• Tire Pressures for Manual Relearn Procedure — expected: LF: 34 PSI, RF: 31 PSI, RR: 29 PSI, LR: 26 PSI.. Failure: This procedure may not work if pressures are not set to these specific, distinct values, as the BCM uses the differences to identify sensor locations.

Scan Tool Commands That Help

• Nissan CONSULT-III plus: TPMS Work Support > ID Regist — This is the official dealer-level command used to write new TPMS sensor IDs to the Body Control Module (BCM) after a sensor has been replaced.
• Autel MaxiTPMS (or similar): Position Relearn > OBD Relearn — This is the common aftermarket tool equivalent of the dealer procedure. The tool reads the new sensor IDs and then writes them to the BCM via the OBD-II port.
• Nissan Signal Tech II (J-50190) + Activation Tool (J-45295-A): Sensor Activation and ID Registration — These are the specific dealer tools used to wake up each sensor and then interface with the vehicle's OBD-II port to upload the new sensor IDs to the TPMS module.

Wiring & Ground Locations

• Body Control Module (BCM) — Located under the driver's side of the dashboard, sometimes specified as being behind the instrument cluster.. The BCM is the central computer that functions as the TPMS receiver. A poor connection, faulty ground, or internal failure of the BCM can cause a 'No Data' condition like C1708.
• TPMS Service Connector — Near the OBD-II port harness under the driver's side dash.. On some older Nissan/Infiniti models, this single-wire connector can be grounded with a paperclip to initiate a manual TPMS relearn mode. However, on the 2014 QX60, this may be a multi-wire plug, making the procedure difficult or impossible for a DIYer.
• BCM Ground — A wiring diagram indicates a ground point at M66, located behind the combination meter (instrument cluster).. A poor or corroded ground connection for the BCM can cause a variety of electrical issues, including the inability to receive signals from the TPMS sensors, leading to a C1708 code.

Real Owner Repair Stories

• Reddit user on r/AskMechanics (2014 Infiniti QX60) — After swapping winter tires for summer tires (both with sensors), the "TPMS error: See owner's manual" message appeared, and the TPMS light flashed for a minute then stayed solid.
  ❌ Tried (didn't work) Setting tires to different PSI and driving for 10 minutes did not trigger an automatic relearn., Attempting the DIY 'paperclip' relearn method by grounding a wire near the OBD-II port. The user found a multi-wire plug instead of the single white wire shown in online tutorials for other models and was unable to proceed.
  ✅ What actually fixed it The user did not post the final resolution, but the story is valuable as it documents a key difference in the DIY relearn procedure for this specific model, indicating a professional scan tool is likely required.

OEM Part Supersession History

• 40700-3JA0A → 40700-3JA0B — Standard part revision by the manufacturer.

Model Year Variations Within This Range

• 2014: The TPMS service connector located near the OBD-II port may be a multi-wire plug, unlike the single-wire connector found on many older Nissan/Infiniti vehicles. This makes the common DIY 'paperclip' relearn method difficult or inapplicable.
