C1708 on 2004-2008 Infiniti G35: TPMS 'No Data' Fault Causes and Fixes

What's Unique About the 2004-2008 Infiniti G35

The Infiniti G35 platform from this era is notably susceptible to radio frequency (RF) interference from aftermarket accessories plugged into the power outlets. Infiniti issued a Technical Service Bulletin (ITB13-039A) 🎬 Watch: Diagnosing TPMS codes C1708 through C1711 on a Nissan/Infiniti. specifically addressing that codes C1708, C1709, C1710, and C1711 can be triggered by devices like "smart cell phone chargers" and aftermarket DVD players. This makes unplugging all accessories the crucial first diagnostic step before assuming a part has failed. Additionally, these models are prone to water leaks from clogged sunroof drains, which can damage 🎬 See how a clogged sunroof drain causes wet floor boards. the BCM in the passenger footwell and cause a host of electrical issues, including TPMS faults.

Diagnostic Flowchart

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

Generation note: This range covers the first generation V35 (2004-2007 coupe, 2004-2006 sedan) and the second generation V36 (2007-2008 sedan). The TPMS system design and common faults like dead sensor batteries and RF interference are consistent across both generations. However, ensure you purchase the correct sensor part number for your specific year and model, as several part numbers and supersessions exist.

Symptoms You May Notice

• TPMS warning light on the dashboard flashes for about one minute after starting the car, then stays on solid.
• Inability to see a pressure reading for one of the tires in the vehicle information display (if equipped).
• Multiple TPMS codes (C1708, C1709, C1710, C1711) may be present simultaneously.

Most Likely Causes

1. Dead TPMS Sensor Battery 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor The non-replaceable batteries inside the original Schrader-made sensors have a lifespan of 5-10 years. Vehicles from 2004-2008 are well past this service life, making battery failure the most common cause.
   How to confirm: Use a TPMS activation tool to try and get a reading from each sensor. The sensor that does not respond or shows a 'low battery' status is the faulty one.
   Typical fix: Replace the failed TPMS sensor. It is highly recommended to replace all four sensors at the same time, as the others are likely to fail soon.
   Est. part cost: $40-$80 per sensor
2. Radio Frequency (RF) Interference 🟡 Medium Probability As documented in TSB ITB13-039A, the TPMS receiver is sensitive to interference from aftermarket electronics (especially 'smart' phone chargers) plugged into the 12V power outlets. The interference blocks the 315MHz signal from the sensors.
   How to confirm: Unplug all aftermarket devices from the power outlets (cigarette lighters). Clear the codes and drive the vehicle for 10-15 minutes to see if the code returns. If it doesn't, one of the devices was the cause.
   Typical fix: Remove or replace the interfering device. This fix costs nothing. Using a high-quality, OEM or certified USB charger can prevent this issue.
   Est. part cost: $0
3. Faulty Body Control Module (BCM) or Receiver ⚪ Low Probability → Shop Body Control Module On G35 models, clogged sunroof drains can cause water to leak into the passenger-side footwell, directly onto the BCM and its wiring harness. This corrosion leads to various electrical faults, including TPMS communication errors.
   How to confirm: Check for dampness or signs of water stains under the passenger-side carpet and around the BCM in the kick panel. If all sensors work and there's no RF interference, a technician must inspect the BCM and the separate TPMS/keyless entry receiver for corrosion or wiring faults.
   Typical fix: First, the water leak from the sunroof drain must be permanently fixed. Then, the corroded BCM may need to be replaced and programmed by a dealer or specialist, or the wiring repaired.
   Est. part cost: $200-$600+

Rare But Worth Checking

• Incorrect Sensor Registration: If the light appeared immediately after a new sensor was installed, it's possible the shop failed to properly register the new sensor's ID to the BCM using a scan tool. This can happen even with new OEM sensors if the registration step is skipped or fails.
• Faulty TPMS Receiver Module: Separate from the BCM, the TPMS receiver (shared with the keyless entry system) can fail. If sensors are good, there is no RF interference, and the BCM appears fine, this module, often located behind the glove box, could be the culprit.

Diagnosis Steps

1. Verify the presence of code C1708 (and any others) with an OBD-II scanner capable of reading C-codes (Chassis).
2. Note the TPMS light behavior: a flashing light for ~1 minute followed by a solid light indicates a system fault, not low pressure.
3. CRITICAL FIRST STEP: Unplug ALL aftermarket accessories from the 12V power outlets (phone chargers, dash cams, etc.).
4. Clear the trouble codes and drive the vehicle for several miles (above 25 MPH). If the light does not return, one of the accessories was causing RF interference.
5. If the light returns, visit a tire shop and have them use a TPMS activation tool to test each wheel sensor. The sensor that fails to respond or shows a low battery is the faulty one.
6. If a sensor is identified as faulty, replace it. It is best practice to replace all four at once due to age.
7. After replacement, ensure the shop registers the new sensor(s) to the BCM using their TPMS tool.
8. If all sensors are transmitting properly, inspect the passenger-side footwell for any signs of moisture, which points to a clogged sunroof drain and potential BCM damage.
9. If no cause is found, the problem may be with the TPMS receiver or the BCM itself, requiring more advanced electrical diagnostics by a professional.

Parts You'll Likely Need

• Tire Pressure Monitoring System (TPMS) Sensor (OEM #40700-JK00B) — The internal, non-replaceable battery is the most common failure point, requiring replacement of the entire sensor unit.
  Trusted brands: Infiniti (OEM), Continental/VDO, Schrader, Denso, Huf, Autel
  OEM price range: $65-$105
  Aftermarket price range: $30-$70

Related Codes That Often Appear With This One

• C1709, C1710, C1711 — These are the corresponding 'No Data' codes for the other three wheels. They often appear together if there is a systemic issue like RF interference, a faulty BCM, or if all sensor batteries have died around the same time.
• U1000 — This is a CAN communication network code. It can appear with TPMS codes if there is a broader electrical issue, such as a failing BCM, that is disrupting communication between modules. Water intrusion is a common cause for both codes appearing together.

Technical Service Bulletins (TSBs) & Recalls

• ITB13-039A: Details diagnostic information for the Low Tire Pressure Warning System, specifically citing radio frequency interference from devices like 'smart cell phone chargers' as a cause for 'No Data' codes C1708, C1709, C1710, and C1711.

Platform-Specific Known Issues

• Radio Frequency Interference: Infiniti Technical Service Bulletin ITB13-039A was issued to address codes C1708-C1711 being caused by radio frequency interference from aftermarket devices, particularly 'smart cell phone chargers', plugged into the vehicle's power outlets.
• BCM Water Damage from Clogged Sunroof Drains: A well-documented issue on G35s is the clogging of the front sunroof drain tubes. This causes rainwater to overflow from the A-pillar and drip directly onto the BCM located in the passenger-side kick panel, leading to corrosion and widespread electrical failures, including TPMS codes.

Mechanic-Grade Diagnostic Values

• DIY Sensor Registration Tire Pressures — expected: Set tires to specific staggered pressures (e.g., RF: 34 psi, LF: 31 psi, LR: 28 psi, RR: 26 psi) before initiating the relearn mode.. Failure: The system will not be able to differentiate wheel locations and the registration will fail if pressures are not set as specified.
• TPMS Sensor Signal Frequency — expected: 315 MHz. Failure: A TPMS tool will detect no signal from the sensor, or the signal will be intermittent.
• BCM Power Supply Voltage — expected: Approximately 12V (Battery Voltage) at the BCM power supply pins with the ignition ON.. Failure: Voltage is significantly below 12V or absent, indicating a wiring, fuse, or fusible link issue.

Hidden / Shadow Codes Worth Checking

• Blink Codes (e.g., 18, 45): Before OBD-II chassis codes were common, grounding a diagnostic connector would cause the TPMS light to blink out a 2-digit code. For example, code 18 indicated a fault with the rear-left tire, while code 45 indicated 'transmitter battery voltage low' for the front-left tire. C1708 is the modern equivalent of a 'no signal' blink code (15, 16, 17, or 18). (see via On applicable models (primarily pre-2007), ground the single-wire TPMS diagnostic connector near the OBD-II port with the key ON and count the flashes of the TPMS warning light.)

Scan Tool Commands That Help

• Nissan CONSULT-II / CONSULT-III: WORK SUPPORT > ID REGIST — This is the dealer-level function required to register new TPMS sensor IDs to the Body Control Module (BCM) after replacing a sensor or rotating tires.
• Autel MaxiTPMS or similar: Position Relearn > OBD Relearn — This is the aftermarket equivalent of the dealer function. 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) or equivalent: Sensor Activation ('Wake Up') — This handheld tool is used to trigger each sensor individually, forcing it to transmit its ID. This is a required step during the 'ID REGIST' procedure and is also the primary method for confirming if a sensor is dead (fails to respond).

Wiring & Ground Locations

• Body Control Module (BCM) — Located in the passenger side footwell, behind the kick panel and glove box area.. The BCM is the master controller for the TPMS. It is notoriously vulnerable to water damage from clogged sunroof drains in this location, which can cause code C1708 and other electrical faults.
• Remote Keyless Entry Receiver — Located behind the glove box, often near the BCM.. This module is the actual receiver for the 315 MHz signals from the wheel sensors. It relays the data to the BCM. A failure of this module can cause all four 'No Data' codes (C1708-C1711) even if the sensors and BCM are good.
• TPMS Diagnostic Service Connector — A single-wire white female connector, typically taped to the main harness near the OBD-II port under the driver's side dash.. This connector is used for manual diagnostics and to initiate the sensor registration/relearn mode on some models by grounding it in a specific sequence.
• BCM Connector M40, Pin 15 — On the main 40-pin connector (often white) that plugs into the BCM.. According to service manual diagrams, this pin carries the signal from the BCM to the TPMS warning light in the instrument cluster. Testing this circuit can help diagnose issues with the warning light itself, separate from the TPMS system.

When the Usual Fixes Don't Work

• In cases where all four codes (C1708-C1711) are present, do not immediately assume all four sensor batteries died simultaneously. While possible, it is critical to first rule out systemic issues. One owner had a tire shop confirm all four sensors were transmitting strong signals, yet the codes persisted. The owner then replaced the TPMS receiver module, which also did not fix the problem, pointing towards a deeper BCM or wiring harness issue. This highlights that even when sensors and the receiver appear functional, the root cause can lie with the BCM or its communication pathways.

OEM Part Supersession History

• 40700-JK00B → 40700-JK01C — Standard part revision by the manufacturer.
  Heads up: 40700-CD001 is another common part number for earlier G35 models; always verify fitment by VIN.
• N/A → N/A — N/A
  Heads up: Aftermarket sensors can be 'direct-fit' (pre-programmed, like VDO SE10007) or 'programmable' (require configuration with a tool before installation, like some Huf or Dorman models). Ensure the shop is aware if you provide a programmable sensor, as it adds a labor step.

Model Year Variations Within This Range

• 2007-2008: For the V36 generation (2007-2008 Sedans), there is no manual procedure to register new TPMS sensors. Registration MUST be done using a compatible scan tool like the Nissan CONSULT or an advanced aftermarket TPMS tool.
• 2004-2006: Earlier V35 generation models may allow for TPMS registration using a manual procedure that involves grounding a service connector and adjusting tire pressures in a specific sequence, similar to programming a key fob.
