C0755 on 2007-2014 Chevrolet Suburban: Right Front TPMS Fault, Causes, and Fixes

What's Unique About the 2007-2014 Chevrolet SUBURBAN

On this generation of Suburban (GMT900), the TPMS sensors communicate with the Remote Control Door Lock Receiver (RCDLR), the same module that receives signals from your key fob. A failing RCDLR can cause both TPMS codes like C0755 and seemingly unrelated issues like poor key fob range, a "Service Tire Monitor System" message, a "Service Theft Deterrent System" message, and even a no-start or stalling condition. This is a well-documented issue, and a factory TSB explicitly links these TPMS codes to no-start problems caused by a faulty security system communication, which relies on the RCDLR.

Most Likely Causes

1. Dead or Faulty Right Front TPMS Sensor 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor The non-rechargeable battery inside the TPMS sensor has a finite lifespan, typically cited as 7-10 years, which perfectly aligns with the age of these vehicles.
   How to confirm: Use a TPMS diagnostic tool to attempt to activate the sensor. If it fails to respond or shows a low battery status, it has failed. This is the most likely cause if C0755 appears alone with no other symptoms.
   Typical fix: Replace the right front TPMS sensor. It is highly recommended to replace all four sensors if they are original, as the others are likely near the end of their service life. A TPMS relearn procedure must be performed after replacement. 🎬 Watch: How to relearn TPMS sensors without using a tool
   Est. part cost: $25-$60 per sensor
2. Faulty Remote Control Door Lock Receiver (RCDLR) Module 🟡 Medium Probability → Shop Keyless Entry Receiver This module is a known failure point on the GMT900 platform. It can fail internally due to component degradation or software glitches, causing it to stop communicating with the BCM and other modules.
   How to confirm: This is the likely cause if C0755 is present with other TPMS codes (C0750, C0760, C0765), key fob issues, and/or no-start/security messages. A professional scan tool will show a "loss of communication" with the RCDLR. Before replacing, check the 'DSM' fuse and inspect wiring.
   Typical fix: Replace the RCDLR module, which is located behind the trim panel in the right rear D-pillar. The new module must be programmed to the vehicle by a dealer or a shop with GM programming capabilities (SPS).
   Est. part cost: $50-$100
3. Wiring or Antenna Connection Issue ⚪ Low Probability The RCDLR antenna coax cable can become disconnected at the module, at the antenna amplifier, or at the rear glass antenna itself. Water intrusion in the rear D-pillar, a known issue, can also corrode connectors and the module itself.
   How to confirm: Visually inspect the RCDLR module and its wiring in the right rear pillar for loose connections, corrosion, or water damage. A GM-specific TSB (#16-NA-061) details how to check the three main connection points of the antenna system. A user on TahoeYukonForum reported their issue was a broken power wire in the driver's door jam.
   Typical fix: Securely reconnect any loose connectors. If corrosion is present, clean the terminals or repair the affected wiring harness section. Repair any broken wires found during inspection.
   Est. part cost: $0-$50 for wiring repair supplies

Rare But Worth Checking

• Blown 'DSM' Fuse: A forum TSB discovery indicates the RCDLR can sometimes go into a 'sleep' mode. The RCDLR receives power through the fuse labeled 'DSM' (Driver Seat Module) in the instrument panel fuse box. Pulling this 10-amp fuse for 30-60 seconds can sometimes reset the module and temporarily restore function. If this works, it strongly points to a failing RCDLR.
• Radio Frequency Interference (RFI): TSB PIC5650K warns that aftermarket electronics, such as LED lights, cell phone chargers, or even toll passes, can emit radio frequencies that interfere with the RCDLR, causing intermittent TPMS, key fob, and starting issues. If symptoms are intermittent and cannot be duplicated, try removing all aftermarket electronic devices from the vehicle to see if the problem resolves.

Diagnosis Steps

1. Scan for all DTCs in all modules. Note if C0755 is alone or present with other TPMS (C07xx), Body (B-codes), or Communication (U-codes) faults.
2. If C0755 is the only code, use a TPMS tool to check the battery status and signal strength of the right front sensor. If it's dead or not responding, replace it.
3. If other TPMS codes or key fob/security issues are present, suspect the RCDLR. First, locate the fuse panel on the driver's side of the dashboard and pull the 10A 'DSM' fuse for 60 seconds, then reinstall it. Test for function.
4. If the fuse pull doesn't work, inspect the vehicle for aftermarket electronics that could cause Radio Frequency Interference (RFI) as per TSB PIC5650K.
5. Gain access to the RCDLR module located behind the trim panel in the right rear cargo area (D-pillar). Some owners report it being on the driver's side D-pillar, so check both if necessary.
6. Inspect the module and its connectors for signs of water damage, corrosion, or loose wires. Check the coax antenna connection.
7. If wiring appears intact, use a multimeter to verify the module is receiving 12V power (typically a red/white wire) and has a good ground (typically a black/white wire) at its connector.
8. If power and ground are present but the module does not communicate (verified with a capable scan tool) and symptoms persist, the RCDLR module has failed and needs to be replaced and programmed.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M (and its revisions like PIC5650K): Links C0755 and other TPMS/security codes to a no-crank, no-start, or start/stall condition, pointing towards a security system fault, often caused by Radio Frequency Interference (RFI) from aftermarket devices or a faulty RCDLR.
• 16-NA-061: Details diagnosis for TPMS and key fob issues caused by disconnected RCDLR antenna system wiring. It outlines three common disconnection points: at the RCDLR module, at the antenna amplifier, and at the rear glass antenna.

Platform-Specific Known Issues

• A known issue on this platform involves the RCDLR module failing or entering a 'sleep' state, causing simultaneous failure of the TPMS and keyless entry systems, and potentially triggering the anti-theft system.
• Water intrusion in the rear D-pillar is a potential cause of RCDLR failure due to its mounting location. A forum user on ChevroletForum.com detailed this exact scenario on their 2012 Tahoe.
• The RCDLR shares a power ci

Hidden / Shadow Codes Worth Checking

• C0755 03: Right Front Tire Pressure Sensor Low Voltage. This indicates a potential power supply or internal sensor electrical fault. (see via A dealer-level scan tool like a GM Tech2 or GDS2 is required to see these symptom/sub-codes.)
• C0755 29: Right Front Tire Pressure Sensor Too Few Pulses. This is a strong indicator of an RCDLR internal failure, as noted in GM TSB #16-NA-396. (see via A dealer-level scan tool like a GM Tech2 or GDS2 is required to see these symptom/sub-codes.)
• C0755 39: Right Front Tire Pressure Sensor Internal Malfunction. This points directly to a failure within the sensor itself, such as a dead battery or damaged component. (see via A dealer-level scan tool like a GM Tech2 or GDS2 is required to see these symptom/sub-codes.)

Scan Tool Commands That Help

• GM Tech2 / GDS2: TPMS Display/Special Functions — Use this function to view live data from each TPMS sensor, including pressure, temperature, and sensor ID. This helps confirm if a specific sensor is not transmitting, which is the first step in diagnosing a single-sensor fault.
• GM Tech2 / GDS2: Module Diagnostics > RCDLR > Data Display — After suspecting an RCDLR failure (multiple TPMS codes, key fob issues), use this to check if the RCDLR module is communicating with the scan tool. A 'No Communication' status confirms the module is offline and likely needs replacement.
• GM Tech2 / GDS2: TPMS Relearn Procedure — This command initiates the vehicle's relearn mode after replacing one or more TPMS sensors. The tool then guides the technician to activate each sensor in sequence to program their positions into the BCM/RCDLR.

Wiring & Ground Locations

• G401 — On the left (driver's side) rear frame rail, near the rear bumper area.. The RCDLR is located in the rear of the vehicle, and its ground circuit is often tied into a nearby chassis ground point. A corroded or loose G401 ground can cause intermittent or total failure of the RCDLR, mimicking an internal module fault and leading to codes like C0755.
• RCDLR Connector — At the RCDLR module, located in the left or right D-pillar in the rear of the vehicle.. Technicians must test for 12V power and ground directly at this connector to confirm the module is receiving power before condemning it. A wiring diagram is needed to identify the specific power (often Red/White) and ground (often Black/White) pins.

Real Owner Repair Stories

• Reddit user in r/gmcsierra (2017 GMC Sierra 1500 SLT (GMT K2XX, similar system)) — Tire maintenance light on, right rear tire not reading pressure. Scan revealed C0750, C0755, C0760, and C0765.
  ❌ Tried (didn't work) Rotating tires did not change the symptom; the right rear position still showed no reading.
  ✅ What actually fixed it The user was advised that having all four TPMS sensor codes appear simultaneously, especially with symptom codes like 'Too Few Pulses' or 'Voltage Below Threshold', strongly points to a faulty RCDLR module rather than four simultaneously failed sensors. The final fix was replacing the RCDLR.

OEM Part Supersession History

• 13598773 → 86363053 — Standard part lifecycle update by GM.
  Heads up: The new part number (86363053) is the direct replacement and should be fully compatible.
• Multiple RCDLR PNs → 25974998 (common) — Consolidation and design updates.
  Heads up: While multiple part numbers may have been used over the 2007-2014 span, it is critical to match the part number on the original RCDLR module or use a VIN-specific catalog. Using a superseded part that is not correct for the specific vehicle's option list can lead to programming failures or inoperative functions.
