C0755 on 2007-2014 GMC Acadia: Right Front TPMS Fault Causes and Fixes

What's Unique About the 2007-2014 Gmc ACADIA

On the first-generation GMC Acadia and its Lambda platform mates (Chevy Traverse, Buick Enclave, Saturn Outlook), TPMS codes can be linked to more severe symptoms than just a warning light. Multiple Technical Service Bulletins (TSB #PIC5650M, #PIC5650K) note that codes like C0755 can appear alongside a no-crank, no-start, or stalling condition accompanied by the security light. This points to a potential communication issue involving the Remote Control Door Lock Receiver (RCDLR), which receives signals for both the TPMS and the key fobs/immobilizer system, making proper diagnosis crucial.

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 flashing for approximately one minute at startup, then staying on solid.
• "Service Tire Monitor System" message on the Driver Information Center (DIC).
• Inability to get a pressure reading for the right front tire on the DIC (often shows '--').
• In rare cases, as noted by TSB PIC5650M/K, may be associated with a no-start or stalling condition and security light.
• If the underlying cause is the RCDLR, symptoms may also include poor key fob range or the "No Fob Detected" message.

Most Likely Causes

1. Dead TPMS Sensor Battery 🔴 High Probability The sealed batteries inside the original 315 MHz sensors have a finite lifespan of 5-10 years. Vehicles in the 2007-2014 range are at or beyond this age, making battery failure the most common cause.
   How to confirm: Use a TPMS diagnostic tool to attempt to activate or read the sensor. If the tool cannot get a response from the right front sensor, but can read the others, the sensor has failed. This is especially true if key fob functions are normal.
   Typical fix: Replace the right front TPMS sensor. 🎬 Watch: This walkthrough shows how to replace a faulty sensor. It is often recommended to replace all four sensors at the same time, especially if they are original and you are already paying for the tire to be dismounted. A relearn procedure is required after replacement.
   Est. part cost: $25-$60 per sensor
2. Damaged TPMS Sensor 🟡 Medium Probability Sensors can be damaged during tire changes, by hitting a pothole, or from internal corrosion, especially if the valve stem cap is missing.
   How to confirm: Visual inspection after dismounting the tire. If the sensor is physically broken, it must be replaced. Sometimes damage is not visible.
   Typical fix: Replace the damaged TPMS sensor and perform the relearn procedure.
   Est. part cost: $25-$60
3. Failure to Relearn After Tire Rotation ⚪ Low Probability If tires were rotated but the TPMS relearn procedure was not performed, the BCM expects the sensor to be in a different location. This can sometimes set a fault code for a sensor it can no longer find in its expected position.
   How to confirm: Perform the TPMS relearn procedure. 🎬 See this video for a quick guide on the relearning process. If the procedure completes successfully for all four tires and the code clears, this was the issue.
   Typical fix: Perform the TPMS relearn procedure using the key fob/DIC method and a TPMS activation tool.
   Est. part cost: $0 (if you own a relearn tool) or minimal shop labor

Rare But Worth Checking

• Faulty Remote Control Door Lock Receiver (RCDLR): The RCDLR is the module that receives signals from all TPMS sensors and key fobs. If it fails, it may not be able to receive the signal from one or more sensors, setting codes C0750, C0755, C0760, or C0765. TSB 16-NA-396 confirms this issue, noting it often occurs with key fob problems. This is a known issue and should be suspected if key fobs are also malfunctioning. Replacement requires programming by a dealer or qualified shop.
• Body Control Module (BCM) or Wiring Issue: A problem with the BCM or the wiring/antenna connection between the RCDLR and BCM can prevent the signal from being processed correctly. TSB 16-NA-061 points to a disconnected coax cable at the RCDLR or its antenna as a possible cause for TPMS codes and poor RKE range. This is very rare and would likely be accompanied by other electrical-related trouble codes.
• Radio Frequency Interference (RFI): TSB PIC5650K warns that aftermarket electronics, such as phone chargers, LED lights, or even toll passes, can emit RFI that 'jams' the 315 MHz or 433 MHz signals used by the TPMS and keyless entry systems, leading to intermittent codes and symptoms. Removing these devices is a key first diagnostic step for intermittent issues.

Diagnosis Steps

1. Verify the code C0755 is present using an OBD-II scanner capable of reading Chassis (C) codes.
2. Check the tire pressure display on the Driver Information Center (DIC). Note if the Right Front tire shows a '--' or no reading.
3. Assess related systems. Check if the key fob (lock/unlock/remote start) is working correctly. If not, suspect the RCDLR module or RFI.
4. Attempt a TPMS relearn procedure. Turn the key to 'ON' (engine off), apply the parking brake, and then hold the lock and unlock buttons on the key fob until the horn chirps twice and the DIC displays 'Tire Learning Active'.
5. Using a TPMS activation tool, start at the Left Front tire and proceed clockwise (LF, RF, RR, LR). Hold the tool against the tire sidewall near the valve stem and press the button. The horn should chirp once for each successful sensor activation.
6. If the horn does not chirp when activating the Right Front sensor, but does for the others, the RF sensor is faulty (likely dead battery) and needs replacement.
7. If the relearn fails for multiple sensors, or if key fob issues are present, investigate the RCDLR module, its antenna wiring, and potential sources of RFI as per TSBs 16-NA-061 and PIC5650K.
8. If the sensor is replaced, the relearn procedure must be performed again to register the new sensor ID with the vehicle's BCM.

Parts You'll Likely Need

• Tire Pressure Monitoring System (TPMS) Sensor (315 MHz) (OEM #13586335, 25920615, 13581558) — This is the direct cause of the fault code in the vast majority of cases due to internal battery failure. It is critical to use the correct 315 MHz frequency sensor for this vehicle generation. The 433 MHz sensor (like part 13598773) is for 2015 and newer models and will not work.

Related Codes That Often Appear With This One

• C0750 — Fault with the Left Front TPMS sensor. It's common for multiple sensor batteries to fail around the same time.
• C0760 — Fault with the Left Rear TPMS sensor. It's common for multiple sensor batteries to fail around the same time.
• C0765 — Fault with the Right Rear TPMS sensor. It's common for multiple sensor batteries to fail around the same time.
• B3055 — As per TSB PIC5650M/K, this key-related immobilizer code can appear with TPMS codes during a no-start condition, suggesting a complex fault with the RCDLR or RFI.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M/K: Notes that C0755 can be found with a no crank, no start, or start/stall concern along with the security light, and advises checking for Radio Frequency Interference (RFI) from aftermarket devices before replacing parts.
• 16-NA-396: Details intermittent key fob operation and TPMS codes caused by an internal failure of the Remote Control Door Lock Receiver (RCDLR), requiring module replacement.
• 16-NA-061: Suggests that TPMS codes and poor key fob range can be caused by a disconnected coax cable or antenna connection for the RCDLR.
• PI1283: Mentions that on some GM vehicles, codes C0750/C0755 can be caused by noise interference while driving, and the fix is an updated RCDLR.

Platform-Specific Known Issues

• TSB PIC5650M/K links this code to potential no-start/stall conditions with the security light illuminated, pointing to a more complex issue with the RCDLR or RFI.
• The 2007-2014 Acadia and its platform mates use a 315 MHz frequency sensor. Using the wrong frequency (e.g., 433 MHz from later models, part #13598773) will not work.
• A faulty RCDLR module is a known failure point on this platform that can mimic a failed TPMS sensor but will also present with key fob range or function issues.

Scan Tool Commands That Help

• Tech 2 / GDS2: RCDLR Setup — This function is required after replacing the Remote Control Door Lock Receiver (RCDLR). It is the first step in the programming sequence before learning keys or TPMS sensors.
• Tech 2 / GDS2: Theft Deterrent System Learn — This must be performed after replacing the RCDLR to allow the vehicle's keys to be recognized and authorize starting the engine. It typically involves a 10 or 30-minute procedure.
• Tech 2 / GDS2: TPM Sensor Learn — This is the final step after RCDLR replacement to program the individual TPMS sensor IDs to the new module. It is also used after a simple sensor replacement or tire rotation.

Wiring & Ground Locations

• RCDLR (Remote Control Door Lock Receiver) — On most Lambda platform vehicles, the RCDLR is located behind the dashboard, often on the passenger side, or above the headliner near the rear of the vehicle. TSB 16-NA-061 shows it located in the right rear quarter panel area on some models.. This module receives the radio frequency signals from all TPMS sensors and key fobs. A failure of the module itself, its power, ground, or antenna connection will cause TPMS codes.
• RCDLR Coaxial Antenna — A coaxial cable runs from the RCDLR to an antenna amplifier module and then to an antenna grid, often located in the right rear quarter glass.. TSB 16-NA-061 specifically calls out that a disconnected coax cable at the RCDLR, the amplifier, or the antenna can cause TPMS codes and poor key fob range. A disconnect closer to the RCDLR will cause more severe symptoms, potentially knocking out all sensors.
• G304 — Located below the floor console.. This is a common interior ground point. A poor connection here could potentially affect various electronic modules located in the center console area.
• G301 / G303 — G301 is located behind the left kick panel. G303 is near the base of the left 'B' pillar.. These are primary grounds for the driver's side of the instrument panel and body harness. The Body Control Module (BCM), which processes the RCDLR data, is located under the left side of the dash and may rely on these grounds.

Real Owner Repair Stories

• CorvetteForum user (2005 Chevrolet Corvette (similar GM RCDLR system)) — "No fob detected" message, requiring a tap on the dash to get the car to start. This points to an intermittent connection.
  ❌ Tried (didn't work) Repinning the connector plugs., Attempting to program a different, used RCDLR module, which failed because the module was locked.
  ✅ What actually fixed it The user was advised that the root cause was likely cold/cracked solder joints on the header pins inside the original RCDLR module. The fix is to remove the RCDLR, open it, and re-solder the board's header pin connections. This resolves the intermittent connection without needing to program a new module.

OEM Part Supersession History

• 13586335 → 13540600, 13598771, 22853741, among others — Standard part evolution and consolidation by the manufacturer.
  Heads up: The key is ensuring the replacement is a 315 MHz sensor. While many part numbers are interchangeable, using a 433 MHz sensor (e.g., from a 2016+ Acadia) will not work on the 2007-2014 generation.

Model Year Variations Within This Range

• 2007-2014: While the core TPMS system and 315 MHz frequency remain consistent through this generation, the physical location of grounds and harness routing may have minor variations between the initial release (2007-2008), mid-cycle (2009-2012), and facelift (2013-2014) models. Always verify wiring diagrams specific to the vehicle's year.
