C0755 on 2015-2022 GMC Yukon: Right Front TPMS Fault Causes & Fixes

What's Unique About the 2015-2022 Gmc YUKON

On this generation of GMC Yukon and its platform mates (Tahoe, Suburban, Escalade), the TPMS sensors communicate with the Remote Control Door Lock Receiver (RCDLR), which also handles key fob signals. A well-documented issue, outlined in GM Technical Service Bulletins PIT5446A and 16-NA-061, is that the coaxial cable for the RCDLR antenna can become disconnected. The antenna system consists of the RCDLR module, a coax cable, an amplifier, and the antenna in the right rear quarter glass. A disconnection at the amplifier or RCDLR module often causes the sensors farthest away (like the right front) to lose connection first, leading a technician to mistakenly replace a good TPMS sensor when the fault is simply a loose wire.

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 end of the fourth generation (2015-2020, K2XX platform) and the beginning of the fifth generation (2021-2022, T1XX platform). The fundamental TPMS and RCDLR architecture is similar, and the key TSBs apply to vehicles in both generations, but specific part numbers for sensors or modules may differ. A critical difference is the TPMS sensor frequency; pre-2021 models typically use 315 MHz sensors, while 2021 and newer models may use 433 MHz sensors, which are not interchangeable.

Symptoms You May Notice

• TPMS warning light flashes for about a minute and then stays illuminated on the dashboard.
• "Service Tire Monitor System" message appears on the Driver Information Center (DIC).
• The pressure reading for the right front tire shows dashes (--) on the DIC.
• Poor range or intermittent operation of the key fob (RKE).
• "No Remote Detected" message on the DIC, especially when seen with other TPMS codes.
• In rare cases, when combined with other security-related codes, it may be associated with a no crank, no start, or start-and-stall condition. [TSB #PIC5650M]

Most Likely Causes

1. Failed TPMS Sensor 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor The non-rechargeable battery inside the sensor has a finite lifespan, typically 7-10 years. Vehicles in the 2015-2022 range are now reaching an age where battery failure is common.
   How to confirm: Use a TPMS activation tool to attempt to read the sensor. If the tool cannot get a response from the sensor, its battery is almost certainly dead or it has failed internally. The activation may need to be attempted multiple times.
   Typical fix: Replace the right front TPMS sensor and perform the TPMS relearn procedure.
   Est. part cost: $25-$75
2. RCDLR Antenna or Coaxial Cable Fault 🟡 Medium Probability As documented in TSB PIT5446A and 16-NA-061, the coaxial cable connecting the RCDLR module to its antenna can become disconnected at one of three points: at the module, at the antenna amplifier, or at the antenna itself in the right rear quarter glass area.
   How to confirm: Inspect the three connection points for the RCDLR antenna system as described in the TSBs. This involves removing trim panels in the right rear cargo area to access the RCDLR module, the antenna amplifier, and the connection to the antenna in the glass. A disconnected cable is a common finding.
   Typical fix: Securely reconnect the coaxial cable and/or antenna amplifier. If the connector is damaged, it may need to be repaired or replaced. A YouTube video by 'FL Trail Rider' titled 'FL TPMS Sensor Antenna Repair Process for '15-'20 Tahoe Suburban Yukon Escalade' shows a detailed repair of the antenna connection at the glass. 🎬 Watch: Step-by-step guide to repairing the antenna connection.
   Est. part cost: $0-$50
3. Faulty Remote Control Door Lock Receiver (RCDLR) ⚪ Low Probability → Shop Keyless Entry Receiver GM issued TSB 16-NA-396 for some vehicles, indicating that internal issues within the RCDLR can cause a loss of communication with both key fobs and TPMS sensors. A user on the Camaro6 forum confirmed this TSB resolved their 'No remote detected' issue.
   How to confirm: This is typically a diagnosis of exclusion. If the sensor is confirmed good and the antenna wiring is intact, but multiple TPMS sensors and key fob functions are inoperative, the RCDLR module itself is the likely culprit. A scan tool may show communication DTCs with the module.
   Typical fix: Replace the RCDLR module. This requires programming by a dealer or a properly equipped independent shop. The part number for the receiver is listed as 13595511 in TSB 16-NA-396, which has been superseded by 13540045.
   Est. part cost: $100-$250

Rare But Worth Checking

• Radio Frequency (RF) Interference: Aftermarket electronic devices like dash cams, phone chargers, or CB radios can sometimes emit RF noise that interferes with the TPMS signals. Before replacing parts, try unplugging all aftermarket accessories to see if the code clears.
• Body Control Module (BCM) Fault: → Shop Body Control Module While rare, an internal fault in the BCM can cause a wide range of electrical issues, including TPMS problems. This is usually accompanied by multiple other unrelated trouble codes.
• RCDLR Memory/Programming Issue: In some cases, the RCDLR module can lose its programming or memory, even if it is not faulty. A user on the Tahoe Yukon Forum reported that after successfully learning the sensors, the system would forget them on the next ignition cycle. The fix was to use a bidirectional scan tool to rewrite the tire type and pressure settings to the RCDLR, which restored normal function.

Diagnosis Steps

1. Manually check the air pressure in all four tires to rule out an actual low-pressure situation.
2. Using a TPMS activation tool, attempt to trigger the right front sensor. If it does not respond, the sensor has likely failed.
3. If the sensor responds to the tool but the vehicle does not register it, proceed to inspect the RCDLR antenna system per TSB PIT5446A/16-NA-061. Check for disconnected coaxial cables at the RCDLR module, the antenna amplifier, and the antenna itself in the right rear quarter panel area.
4. Scan the BCM for other trouble codes. If codes for multiple sensors (C0750, C0760, C0765) or keyless entry are present, it points more strongly toward a central receiver issue (RCDLR) rather than a single sensor failure.
5. If the sensor is good and the antenna wiring is secure, and other related codes are present, further diagnosis of the RCDLR module and BCM is required. Consider the possibility of a faulty RCDLR module per TSB 16-NA-396.
6. After any repair, perform the TPMS relearn procedure to ensure the vehicle correctly identifies the position of each sensor.

Related Codes That Often Appear With This One

• C0750, C0760, C0765 — These are the codes for the other three wheel sensors (Left Front, Left Rear, Right Rear). If the RCDLR antenna or module is failing, it's common to see codes for multiple wheels set at the same time.
• B3055, B3060, B3935 — As noted in TSB PIC5650M, these security and key-related codes can appear alongside TPMS codes when there is a fault in a shared module like the RCDLR, potentially leading to no-start conditions.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M: No crank, no start, or start stall concern with the security light coming on.
• PIT5446A: Service Tire Monitor System/Tire Pressures Display Dashes/RKE Short Range.
• 16-NA-061: A later version of PIT5446A, reiterating the RCDLR antenna connection issue for newer model years.
• 16-NA-396: Intermittent Operation of Key Fobs, Door Unlock Inoperative “No Remote Detected” Message with Possible TPM MIL.

Platform-Specific Known Issues

• TSB PIT5446A / 16-NA-061: Warns of a disconnected Remote Control Door Lock Receiver (RCDLR) antenna or coax cable causing one or more TPMS sensors to stop reporting, along with poor key fob range. It advises checking these connections before replacing any parts.
• TSB 16-NA-396: Addresses intermittent operation of key fobs and TPMS sensor codes due to internal failures of the RCDLR module, recommending replacement of the module (P/N 13595511) if diagnosed.
• TSB PIC5650M: Links TPMS codes, including C0755, with various security system codes that can result in a no-start or start-and-stall condition, pointing to a potential BCM or related module issue.

Mechanic-Grade Diagnostic Values

• High Speed GMLAN Bus Resistance — expected: 60 Ω (Ohms) ± 3 Ω. Failure: A reading significantly different from 60 Ω, especially a lower reading, indicates a short on the data bus or a problem with a terminating resistor in a module (like the ECM or EBCM).
• TPMS DTC Set Time — expected: N/A. Failure: A code like C0755 will set if a sensor does not transmit for 18 minutes while the vehicle speed is above 25 mph (40 km/h).

Hidden / Shadow Codes Worth Checking

• C0755 03: Right Front Tire Pressure Sensor Low Voltage. This indicates a potential issue with the sensor's battery or internal electronics causing a low voltage condition. (see via A professional scan tool like the GM GDS2 can read these manufacturer-specific sub-codes.)
• C0755 29: Right Front Tire Pressure Sensor Too Few Pulses. The RCDLR is not receiving the expected number of data packets from the sensor. (see via A professional scan tool like the GM GDS2 can read these manufacturer-specific sub-codes.)
• C0755 39: Right Front Tire Pressure Sensor Internal Malfunction. The sensor has performed a self-test and detected an internal failure. (see via A professional scan tool like the GM GDS2 can read these manufacturer-specific sub-codes.)

Scan Tool Commands That Help

• GM GDS2: Monitor 'Tire Pressure Sensor Mode' Parameter — When diagnosing a sensor that won't learn or drops out, monitor this live data parameter in the BCM or RCDLR data list. While driving above 25 mph, the sensor mode should change from a stationary mode to 'Drive' or 'Rolling'. If it doesn't, it confirms the sensor is not transmitting correctly.
• TPMS Activation Tool (e.g., EL-50448, EL-52545): Activate Sensor — This is used during the manual relearn procedure to force each sensor to transmit its ID to the vehicle. It's also used as a basic check; if the tool cannot activate the sensor at all, the sensor itself (or its battery) has failed.

Wiring & Ground Locations

• RCDLR Module — Located in the right rear quarter panel area, typically behind the trim.. This module is the receiver for all TPMS signals. A loose coaxial antenna connection at this module is a primary cause for TPMS codes, as noted in TSB 16-NA-061.
• RCDLR Antenna Amplifier — Located near the RCDLR module, between the module and the in-glass antenna.. A loose coaxial connection at this amplifier can cause intermittent loss of signal from sensors farther away, such as the right front.
• G304 — A chassis ground point located at the base of the right 'B' pillar, behind the trim panel.. This is a primary ground point in the vicinity of the RCDLR. A poor connection at G304 could cause erratic behavior or failure of the RCDLR module, leading to TPMS codes.

Real Owner Repair Stories

• YouTube channel 'FL Trail Rider' (2015-2020 GM SUV (Tahoe/Suburban/Yukon/Escalade platform)) — Reduced key fob entry range and intermittent loss of communication with the front left TPMS sensor.
  ❌ Tried (didn't work) The video implies that simply replacing the sensor would not have fixed the root cause.
  ✅ What actually fixed it The solder points for the RCDLR antenna amplifier connection on the right rear quarter glass had failed. The fix involved re-soldering the metal contacts for the amplifier directly onto the glass antenna grid, which permanently restored the connection and resolved the symptoms.
• Reddit user on r/gmcsierra (2017 GMC Sierra 1500 SLT with 181k miles) — 'Service Tire Monitor' light on. The DIC was not reading the right rear tire, but after a tire rotation, it was still the right rear position showing no reading. A scan revealed codes C0750, C0755, C0760, and C0765 were all present.
  ❌ Tried (didn't work) Rotating tires to see if the problem followed a specific sensor (it did not)., Clearing codes (they returned immediately).
  ✅ What actually fixed it The user was seeking advice, but the reported pattern of all four TPMS codes setting simultaneously after a single sensor position initially failed is a classic real-world example of a central system failure (RCDLR module or its antenna circuit), not an individual sensor fault.

OEM Part Supersession History

• 13595511 → 13540045 — Standard part revision by the manufacturer for improvements or supplier changes.
  Heads up: The new part number should be a direct replacement, but programming is still required after installation.

Model Year Variations Within This Range

• 2021-2022: Vehicles in the T1XX generation (2021+) may use a 433 MHz TPMS sensor frequency, whereas the earlier K2XX generation (2015-2020) typically uses 315 MHz. The frequencies are not interchangeable, and using the wrong sensor will cause the system to fail. Always verify the correct frequency by VIN before purchasing new sensors.
