C0755 on 2007-2014 GMC Sierra 1500: Right Front TPMS Fault Causes and Fixes

What's Unique About the 2007-2014 Gmc SIERRA 1500

What's unusual about this code on the GMT900 platform (which includes the 2007-2014 Sierra) is its potential link to no-start and security issues. The module that receives the TPMS signal, the Remote Control Door Lock Receiver (RCDLR), also handles key fob inputs for the security and remote entry systems. A fault in this shared module or radio frequency interference (RFI) from aftermarket electronics can disrupt both systems. This can present as both a TPMS code like C0755 and a no-crank/no-start condition with the security light on, as documented in TSB PIC5650M, confusing diagnostics.

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 GMT900 (2007-2013) and the first year of the K2XX (2014) generation. The function of the TPMS is the same, but the relearn procedure can vary slightly. 2007 models may use a headlight switch method to enter learn mode, while later models typically use the Driver Information Center (DIC) buttons or a key fob press (lock and unlock simultaneously) to initiate the process. A tool-free relearn 🎬 See this DIY guide for a tool-free TPMS relearn. is possible by letting air out of each tire in sequence, but using a TPMS activation tool is much faster and more reliable.

Symptoms You May Notice

• "Service Tire Monitor System" message on the Driver Information Center (DIC).
• TPMS warning light is illuminated on the dashboard (may flash for one minute, then stay solid).
• The tire pressure display for the right front tire shows dashes "--" instead of a pressure reading.
• In rare cases, may be accompanied by a security light and a no-start or stalling condition. [TSB #PIC5650M]
• Key fob may not work for locking/unlocking doors or remote start.

Most Likely Causes

1. Dead or Dying TPMS Sensor Battery 🔴 High Probability TPMS sensors use sealed, non-replaceable batteries with a finite lifespan, typically 7-10 years. Vehicles in this 2007-2014 year range are at or beyond the typical life expectancy of the original sensors, making battery failure the most common cause.
   How to confirm: Use a TPMS diagnostic tool to attempt to activate the right front sensor. If the tool shows a 'Low Battery' status or gets no response while other sensors respond, the battery is dead. A professional scan tool can also read the battery status directly from the BCM/RCDLR data stream.
   Typical fix: Replace the right front TPMS sensor and perform a TPMS relearn procedure. It is often recommended to replace all four sensors if they are original, as the others are likely to fail soon.
   Est. part cost: $30-$70
2. Internal Failure of TPMS Sensor 🟡 Medium Probability Sensors can be damaged during tire changes or fail from age, corrosion, or vibration. This is common across all vehicles with direct TPMS.
   How to confirm: A TPMS tool will fail to read the sensor, or may pull a specific 'Internal Malfunction' fault code. If a scan tool shows the battery status is OK but the sensor won't transmit pressure data, it has failed internally.
   Typical fix: Replace the right front TPMS sensor and perform a TPMS relearn procedure.
   Est. part cost: $30-$70
3. Faulty Remote Control Door Lock Receiver (RCDLR) ⚪ Low Probability
   How to confirm: If a TPMS tool confirms all four sensors are transmitting but the codes persist, the RCDLR is suspect. A professional scan tool is needed to check communication between the BCM and RCDLR. TSB 16-NA-396 specifically points to an internal RCDLR fault when multiple TPMS codes are set with symptom code 29 ('Too Few Pulses').
   Typical fix: Replace and program the RCDLR module. The module is typically located behind the driver's side rear quarter panel trim (D-pillar).
   Est. part cost: $80-$150

Rare But Worth Checking

• Radio Frequency Interference (RFI): Aftermarket electronic devices can broadcast radio signals that 'jam' the 315 MHz frequency used by the TPMS sensors and key fobs.
• Wiring Harness Issue: A break or short in the wiring to the RCDLR module can prevent it from receiving power or communicating with the BCM.

Diagnosis Steps

1. Verify the tire pressure in the right front tire is correct using a manual gauge.
2. Check for Radio Frequency Interference (RFI). Unplug ALL aftermarket accessories (phone chargers, dash cams, LED lights, etc.) and see if the code clears and the system operates normally. This is a key step recommended by GM TSB PIC5650.
3. Use a TPMS activation tool to test the right front sensor. Check if it transmits its ID, temperature, pressure, and battery status.
4. If the tool gets no response from the right front sensor, but reads the other three sensors successfully, the right front sensor is faulty and needs replacement.
5. If the tool reads the sensor but shows 'Low Battery', the sensor needs replacement.
6. If all sensors test good with the tool but the code remains, the problem may be with the Remote Control Door Lock Receiver (RCDLR) or its wiring. Check for other TPMS codes or key fob issues.
7. Inspect the wiring and connector at the RCDLR, located behind the driver's side D-pillar trim, for power, ground, and any signs of damage.
8. After replacing a sensor, perform the TPMS relearn procedure to register the new sensor ID with the vehicle.

Parts You'll Likely Need

• Tire Pressure Monitoring System (TPMS) Sensor (OEM #13598772) — This is the most common failure point. The internal battery dies, or the sensor itself fails, triggering code C0755. This part number is a widely used 315MHz sensor for many GM vehicles of this era.

Related Codes That Often Appear With This One

• C0750 — Indicates a fault with the Left Front TPMS sensor. Seeing multiple TPMS codes together can point towards a central module (RCDLR) issue rather than individual sensors.
• C0760 — Indicates a fault with the Left Rear TPMS sensor.
• C0765 — Indicates a fault with the Right Rear TPMS sensor.
• B3055 — A key-related security code. Its presence with C0755 strongly suggests a fault in the RCDLR or RFI, as noted in TSB PIC5650M, which handles both TPMS and security functions.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M: Addresses a potential no-crank, no-start, or stall concern that can be accompanied by various security and TPMS codes, including C0755. It strongly suggests checking for aftermarket radio frequency interference before replacing parts.
• 16-NA-396: Details issues with intermittent key fob and TPMS operation due to an internal RCDLR fault, often identified by symptom code :29 ('Too Few Pulses').

Platform-Specific Known Issues

• TSB PIC5650M documents a condition where TPMS codes, including C0755, can appear alongside security system codes (like B3055) and cause a no-crank, no-start, or stalling issue. This points to a potential software or hardware fault in a shared control module (RCDLR or BCM). The primary cause identified is often Radio Frequency Interference (RFI) from aftermarket devices like phone chargers or LED lights.
• TSB 16-NA-396 addresses intermittent operation of key fobs and TPMS, pointing to an internal fault in the RCDLR when multiple TPMS codes are present. This bulletin applies to many GM vehicles and suggests replacing the RCDLR module.

Mechanic-Grade Diagnostic Values

• RCDLR Module Power Supply — expected: 12V at the module connector. Failure: 0V or significantly low voltage indicates a broken wire or blown fuse, even if a new RCDLR is installed.
• TPMS Sensor Signal Frequency — expected: 315 MHz. Failure: No signal detected by a TPMS tool.

Hidden / Shadow Codes Worth Checking

• C0755 :03: Right Front Tire Pressure Sensor Low Voltage. This strongly indicates the sensor's internal battery is dying. (see via GM Tech 2, GDS2, or a high-end professional scan tool capable of reading manufacturer-specific symptom bytes.)
• C0755 :29: Right Front Tire Pressure Sensor Too Few Pulses. TSB 16-NA-396 links this specific symptom code to an internal failure of the RCDLR module, especially when multiple TPMS codes are present. (see via GM Tech 2, GDS2, or a high-end professional scan tool.)
• C0755 :39: Right Front Tire Pressure Sensor Internal Malfunction. This points directly to a hardware failure within the sensor itself. (see via GM Tech 2, GDS2, or a high-end professional scan tool.)
• C0755 :08: Right Front Tire Pressure Sensor Signal Invalid. This indicates the RCDLR is receiving a signal, but the data is corrupt or not plausible. (see via GM Tech 2, GDS2, or a high-end professional scan tool.)

Scan Tool Commands That Help

• GDS2 / Tech 2: TPMS Relearn Procedure — After replacing a TPMS sensor or rotating tires, this guided function is used with a TPMS activation tool to make the RCDLR learn the new sensor IDs and their positions on the vehicle.
• GDS2 / Tech 2: RCDLR Data Display -> Sensor Battery Status — To confirm a suspected dead or dying sensor battery without dismounting the tire. The scan tool can display the battery status as reported by the sensor to the RCDLR.
• GDS2: Module Diagnostics -> RCDLR -> Configure/Reset Functions -> Add/Replace Key Fobs — This function is required after replacing the RCDLR module to program the existing (or new) key fobs to the new module. Failure to do this will result in the key fobs not working.

Wiring & Ground Locations

• RCDLR Module — Typically located behind the upper trim panel of the driver's side D-pillar (the rearmost pillar) in GMT900 trucks and SUVs.. This is the receiver for the TPMS sensor signals. All diagnostic paths for persistent codes eventually lead to checking this module and its connections.
• DSM Fuse (10A) — Located in the instrument panel fuse block, on the driver's side of the dashboard.. This fuse provides power to the RCDLR. A loss of communication with the RCDLR can be caused by a blown fuse or a break in the power wire originating from this circuit.
• Ground G103 — Located on the cowl in the left rear of the engine compartment, often near the brake booster.. This is a key ground point for the RCDLR. A loose or corroded G103 is a known cause for various electronic issues on GM trucks, including module communication faults.

Real Owner Repair Stories

• YouTube channel 'Raymond's World' (2011 Chevrolet Silverado) — No communication with the RCDLR, key fobs not working.
  ❌ Tried (didn't work) Replacing the RCDLR module with a new one did not solve the 'no communication' issue.
  ✅ What actually fixed it The technician tested for power at the RCDLR connector and found 0V. He traced the power wire from the 10A DSM fuse and found a break in the wire along the driver's side sill plate area. Repairing the broken wire restored power to the module and fixed the problem.
• YouTube channel 'Wires 2 Wrenches' (2008 Chevrolet Silverado) — Intermittent no-start, 'Service TPMS' message, key fobs not working, erratic DIC behavior. Problems were worse after rainfall.
  ❌ Tried (didn't work) Initial diagnosis pointed towards a faulty module or wiring harness chafe.
  ✅ What actually fixed it The root cause was a leaking gasket on the third brake light on the cab roof. Water was getting in, running down the pillar, and dripping onto CAN bus wiring connectors, causing widespread communication issues that affected the RCDLR. The final fix was to seal the third brake light housing with silicone to stop the water leak and ensure the affected connectors were clean and dry.
