C0760 on 2007-2014 Cadillac Escalade: Left Rear TPMS Fault and Fixes

What's Unique About the 2007-2014 Cadillac ESCALADE

For the third-generation (GMT900) Escalade and its platform mates (Tahoe, Yukon, Suburban), the key thing to understand is that the Tire Pressure Monitoring System (TPMS) and the keyless entry/security system are handled by the same module: the Remote Control Door Lock Receiver (RCDLR). This module is typically located behind the interior trim panel in the driver's side rear cargo area (D-pillar). This is why a simple TPMS code like C0760 can sometimes appear alongside much more serious symptoms like a no-start condition or inoperative key fobs. While the code points to a tire sensor, the root cause on this platform can often be the central RCDLR module failing, which creates a confusing mix of tire and security-related problems that appear simultaneously.

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 is illuminated on the dashboard (may flash for 60 seconds on startup, then stay solid).
• "Service Tire Monitor System" message appears on the Driver Information Center (DIC).
• The DIC shows dashes (---) for the left rear tire pressure reading, and often for other or all tires.
• Engine does not start or starts and immediately stalls (when part of a larger module failure).
• Security indicator light is on.
• "No Remote Detected" message on the DIC, even with the key fob inside the vehicle.
• Key fob is intermittently or completely inoperative (lock/unlock/remote start).
• Reduced range for the key fob (e.g., only works when very close to the vehicle).

Most Likely Causes

1. Dead or Faulty Left Rear TPMS Sensor 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor TPMS sensor batteries have a finite lifespan, typically 7-10 years. For this vehicle range, many original sensors are at or beyond their expected service life.
   How to confirm: Use a TPMS diagnostic tool to attempt to read the sensor's signal, battery status, and pressure. If the tool cannot get a reading from only the left rear sensor while others respond, the sensor is bad.
   Typical fix: Replace the left rear TPMS sensor and perform the TPMS relearn procedure. 🎬 Watch: A step-by-step guide to replacing the tire pressure sensor.
   Est. part cost: $40-$90
2. Faulty Remote Control Door Lock Receiver (RCDLR) 🟡 Medium Probability → Shop Keyless Entry Receiver The RCDLR is a known failure point on many GM platforms that can cause simultaneous TPMS and keyless entry system faults. Forum discussions frequently point to this module as the culprit when multiple TPMS codes appear with key fob issues.
   How to confirm: Diagnose this by observing a combination of symptoms: multiple TPMS codes (C0750, C0755, C0760, C0765) appearing at the same time, plus key fob/remote start malfunctions and 'No Remote Detected' messages. If all four sensors fail at once, the RCDLR is the primary suspect.
   Typical fix: Replace the RCDLR module, which is located behind the driver's side rear quarter panel trim. This part must be programmed to the vehicle by a dealer or a shop with GM programming capabilities (SPS).
   Est. part cost: $100-$250
3. General Electrical or BCM Issue ⚪ Low Probability As noted in TSB #PIC5650M and its successors, a no-start or stall condition with the security light can be accompanied by a host of seemingly unrelated codes, including C0760.
   How to confirm: Scan all vehicle modules. If numerous communication (U-codes) and body (B-codes) faults are present along with C0760 and a no-start condition, suspect a failing Body Control Module (BCM) or a major power/ground issue.
   Typical fix: Diagnose and repair the underlying electrical fault or replace and program the BCM.
   Est. part cost: $300-$600

Rare But Worth Checking

• Radio Frequency (RF) Interference: Aftermarket electronic devices like phone chargers, dash cams, LED lighting, or even toll passes can sometimes emit RF interference that blocks the RCDLR from receiving signals. TSB PIC5650K provides a long list of potential sources. Before replacing parts, try unplugging all aftermarket accessories.
• Wiring or Antenna Connection Issue: A poor connection at the RCDLR module, its antenna, or a broken wire in the harness can cause identical symptoms to a failed module. One owner on a forum reported that a broken power wire in the driver's door jamb was the ultimate cause. TSB 16-NA-061 details how a disconnected coax cable for the RCDLR antenna can cause these issues.

Diagnosis Steps

1. Scan for codes in ALL vehicle modules, not just the engine computer. Save the full code list.
2. Analyze the codes. Is C0760 the only code? Or is it accompanied by all other TPMS codes (C0750, C0755, C0765), key fob codes (B-codes), or communication codes (U-codes)?
3. Scenario A: C0760 is the only code. The problem is likely the sensor itself. Use a TPMS tool to check the left rear sensor's battery and signal output. If it's dead, replace the sensor and perform the relearn procedure.
4. Scenario B: C0760 is present with multiple other TPMS codes AND key fob/security codes/no-start condition. The RCDLR is the primary suspect. Do not replace the tire sensors first.
5. Check for RF Interference. Unplug ALL aftermarket electronics (phone chargers, dash cams, LED bulbs, etc.) and remove toll passes from the vehicle. Retest functionality.
6. Inspect the vehicle's battery and primary ground connections. Low voltage (below 9V) can cause modules to malfunction. A forum user traced a similar issue to a corroded power wire leading to the RCDLR.
7. If the RCDLR is suspected, locate it behind the driver's side rear D-pillar trim panel and inspect the wiring and antenna connections for damage or looseness, including the coax cable and ground G302.
8. If connections are good, the RCDLR likely needs replacement. This requires programming with a GM scan tool after installation. One owner noted they replaced the part themselves but had to have the vehicle towed for dealer programming.
9. After any repair (sensor or module replacement), the appropriate relearn/programming procedure must be performed.

Parts You'll Likely Need

• Tire Pressure Monitoring System (TPMS) Sensor (OEM #13598771 (This number supersedes older part numbers like 13516164).) — This is the most common fix when C0760 appears alone. The internal battery dies, requiring replacement of the entire sensor unit.
  Trusted brands: ACDelco, Schrader, Continental
  OEM price range: $60-$100
  Aftermarket price range: $40-$70
• Remote Control Door Lock Receiver (RCDLR) (OEM #22860421, 25976816, 20803735 (Part number can vary by year and options. ALWAYS verify with VIN before ordering).) — This module is the likely cause when TPMS codes appear with key fob or starting problems. It receives signals for both systems, and an internal failure affects both.
  Trusted brands: ACDelco (GM Genuine)
  OEM price range: $100-$250

Related Codes That Often Appear With This One

• C0750, C0755, C0765 — These are the corresponding TPMS codes for the other three wheels (LF, RF, RR). When they appear together, it points strongly to a central receiver problem (RCDLR) rather than four simultaneously failed sensors.
• B3055, B3060 — These are security and key-related codes. When seen with C0760 and a no-start condition, it points to a central module failure (BCM or RCDLR) as described in TSB PIC5650M.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M (and subsequent versions like K): Notes that C0760 can appear with security codes (B3055, B3060) and a no-start or stall condition, pointing to a wider electrical issue, often related to Radio Frequency Interference (RFI) from aftermarket devices.
• 16-NA-061 / PIT5446: While for slightly newer models, these TSBs are relevant as they identify a disconnected RCDLR antenna or wiring as the cause for simultaneous TPMS

Platform-Specific Known Issues

• A known issue, documented in TSB #PIC5650M, involves a no-start or stall condition with security lights, where TPMS codes like C0760 can be set as a secondary symptom of a larger electrical problem, potentially with the BCM or due to RF interference.
• The Remote Control Door Lock Receiver (RCDLR) is a very common failure point on GMT900 platform vehicles, causing simultaneous TPMS and keyless entry system faults. This is widely discussed in owner forums for the Escalade, Tahoe, and Yukon.

Mechanic-Grade Diagnostic Values

• RCDLR Power Supply Voltage — expected: 12V DC. Failure: 0V or significantly less than 12V indicates a broken wire or blown fuse.
• RCDLR Module Operating Voltage — expected: 9-16 Volts. Failure: Voltage outside this range can cause unpredictable module behavior.

Hidden / Shadow Codes Worth Checking

• C0760 with Symptom :29: Translates to 'Too Few Pulses'. This indicates the RCDLR is receiving an incomplete or corrupted data packet from the sensor, pointing towards a weak sensor, RFI, or an internal RCDLR fault rather than a completely dead sensor. (see via GM GDS2 (Global Diagnostic System 2) or equivalent professional scan tool.)
• C0760 with Symptom :08: Translates to 'Bus Signal/Message Failure'. This indicates a communication breakdown on the data bus related to the sensor's signal. (see via GM GDS2 (Global Diagnostic System 2) or equivalent professional scan tool.)

Scan Tool Commands That Help

• GDS2 / Tech 2: RCDLR Setup / Module Setup — This function must be performed after installing a new RCDLR to integrate it with the vehicle's other modules.
• GDS2 / Tech 2: Theft Deterrent System Learn — Required after RCDLR replacement to re-link the vehicle's anti-theft system and keys to the new module.
• GDS2 / Tech 2 / TPMS Tool: Tire Pressure Indicator Sensor Learn — After replacing a TPMS sensor or the RCDLR, this procedure matches each sensor's unique ID to its position on the vehicle.
• GDS2: Add/Replace Key Fobs — Used to program new or existing key fobs to a new RCDLR. The path is typically 'Module Diagnostics' -> 'Remote Control Door Lock Receiver' -> 'Configure and Reset Functions'.

Wiring & Ground Locations

• RCDLR Module — Behind the driver's side D-pillar trim panel in the rear cargo area.. This is the central receiver for all TPMS and key fob signals. Access is required for replacement or to test its connections.
• G302 — Ground stud located on the passenger side front door sill, under the sill plate/trim.. This is the specific ground point for the RCDLR module. A poor connection here will cause the RCDLR to malfunction, creating TPMS and key fob issues.
• RCDLR Connector Pin 1 (RD/WH wire) — At the RCDLR module connector.. This is the 12V+ power supply wire from the 10A 'DSM' fuse. It should have 12V with the key on. Loss of voltage here means a wiring break or fuse issue, not a bad RCDLR.
• RCDLR Antenna System — Consists of a coax cable running from the RCDLR to an antenna amplifier module, which then connects to the antenna grid in the right rear glass.. A disconnect at the module, amplifier, or glass will cause loss of signal from the TPMS sensors and key fobs, mimicking a failed RCDLR. Symptoms are worse the closer the disconnect is to the module.

Real Owner Repair Stories

• MHH Auto forum user 'TallersDiesel' (2009 Cadillac Escalade) — TPMS issues and key fobs not working.
  ❌ Tried (didn't work) Initial visual checks.
  ✅ What actually fixed it The user confirmed the RCDLR was not receiving power on its Red/White wire. By supplying a temporary 12V from another module, all TPMS and key fob functions were restored. This proved the RCDLR module was good and the fault was a broken power wire between the fuse box and the module.
• Tahoe Yukon Forum user 'cnc-97' (2009 Cadillac Escalade ESV (Limousine Conversion)) — TPMS and Keyless Entry not working.
  ❌ Tried (didn't work) Pulling the 10-amp fuse., Unplugging and reconnecting the RCDLR.
  ✅ What actually fixed it Replaced the RCDLR with a used module from a 2011 Impala for $5.00 from a salvage yard. After installing the used module, the user performed the key fob programming procedure, which resolved both the TPMS and keyless entry issues.

"I Checked Everything" — The Actual Cause

• A common scenario is that the RCDLR module itself is functional, but it has lost its 12V power supply due to a corroded or broken Red/White wire running from the instrument panel fuse box. A technician confirmed this by supplying a temporary fused 12V directly to the module's power pin, which immediately restored all functions and proved the module itself was not the point of failure.

OEM Part Supersession History

• 13516164, 13586335, 20923680, 22853741, and others → 13598771 — Consolidation and updates to the TPMS sensor design.
• 13598771 → 13540600 — Further part design updates.
• 15857831 (RCDLR) → Part numbers starting with 2038#### or 25###### — Module hardware/software revisions.
  Heads up: According to forum users, newer part numbers are often backward compatible as direct replacements.

Model Year Variations Within This Range

• 2007-2014 (GMT900) vs 2015+ (K2XX): TPMS sensors from the next generation (2015+) are not compatible with the 2007-2014 GMT900 system, even if the wheels physically fit. The systems operate differently and the sensors cannot be learned by the older RCDLR.
