C0755 on 2016-2023 Buick Envision: TPMS, No-Start, and RCDLR Fixes

What's Unique About the 2016-2023 Buick ENVISION

On many vehicles, a TPMS code is a minor annoyance. However, on this generation of Buick Envision and other GM platforms, it can be a critical failure. The system design consolidates the receiver for the key fobs (security) and the TPMS sensors into a single module called the Remote Control Door Lock Receiver (RCDLR). A fault within this module, as documented in GM TSB #16-NA-396, or significant radio frequency interference, can disrupt both systems simultaneously. This is why a seemingly simple tire sensor code (C0755) can present with severe security-related symptoms like a no-start condition, a scenario also detailed in GM TSB #PIC5650M.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Generation note: The 2016-2023 model years span two generations of the Buick Envision (First Gen: 2016-2020, Second Gen: 2021-2023). The system architecture using a combined RCDLR module is common across modern GM vehicles, and TSBs #PIC5650M and #16-NA-396 cover years from both generations, indicating the potential for this issue exists in both.

Symptoms You May Notice

Most Likely Causes

1. Failed Right Front TPMS Sensor 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor TPMS sensors are powered by non-rechargeable lithium batteries with a finite lifespan, typically 5-10 years. Vehicles in this year range are reaching the age where original sensor batteries are expected to fail.
   How to confirm: Use a TPMS activation tool to attempt to read the sensor. If the tool cannot get a signal from the right front sensor but can from the other three, the sensor is almost certainly the cause. A professional scan tool can also identify a 'Sensor Low Battery' condition.
   Typical fix: Replace the TPMS sensor in the right front wheel. The new sensor must be 'relearned' to the vehicle using a specific procedure, which often requires a TPMS tool. 🎬 See how to relearn and reset your TPMS sensors
   Est. part cost: $25-$75
2. Faulty Remote Control Door Lock Receiver (RCDLR) 🟡 Medium Probability → Shop Keyless Entry Receiver This module is a known failure point across many GM vehicles. TSB #16-NA-396 explicitly states that an internal issue can cause this fault. It processes signals from both TPMS and key fobs, and an internal fault can generate TPMS codes and cause security/starting issues.
   How to confirm: This is diagnosed when a new TPMS sensor doesn't fix the code, or when TPMS codes appear alongside key fob and no-start issues. A professional scan tool can check for communication with the RCDLR and may find internal module faults or communication DTCs. A technician may also hear only a single click from the RCDLR when pressing the start button, instead of a series of clicks, indicating an internal failure.
   Typical fix: Replace the RCDLR module. This part MUST be programmed to the vehicle by a dealer or a qualified independent shop with GM diagnostic software (GDS2 and SPS).
   Est. part cost: $70-$180
3. Radio Frequency Interference (RFI) ⚪ Low Probability As noted in TSB PIC5650K, the 125 kHz, 315 MHz, and 433 MHz frequencies used by the key fob and TPMS systems are easily 'jammed'. Common sources include aftermarket phone chargers, LED lights (dome, tail, strip lights), dash cams, toll passes, and even other vehicle key fobs on the same keychain.
   How to confirm: Remove all aftermarket electronic devices plugged into power outlets and remove all other keys, fobs, and access cards from the key ring. If the problem disappears, one of the removed items was the cause. A technician can also use a special tool (like the J-43241 or EL-52545) to scan for stray RF signals.
   Typical fix: Stop using the device that is causing the interference in the vehicle.

Rare But Worth Checking

• Body Control Module (BCM) Issue: → Shop Body Control Module While rare, a software glitch or internal failure in the BCM could cause it to misinterpret data from the RCDLR. This would typically require BCM reprogramming or replacement by a professional. GM now recommends reprogramming modules with the latest software before replacement.
• Wiring/Connector Damage: Damage to the wiring or connectors for the RCDLR, or its antenna (often in the rear of the vehicle), could cause intermittent signal loss. This would require a visual inspection and continuity testing of the harness. A poor ground connection at a location like G103 can also cause this issue.

Diagnosis Steps

1. Scan the vehicle for all DTCs in all modules. Note if C0755 is present alone or with other TPMS or B-prefix (Body/Security) codes like B3055 or B3060.
2. If only C0755 is present and the only symptom is the TPMS light, use a TPMS tool to check the battery and function of the right front sensor. If it fails to read, the sensor is the likely culprit.
3. If you have no-start/key fob symptoms, attempt to start the vehicle by placing the key fob in the designated transmitter pocket (usually in the center console). If it starts, this points strongly to RFI or a weak fob battery.

4. Consult TSB #PIC5650K. Thoroughly check for and remove any aftermarket electronics (phone chargers, dash cams, LED lights, etc.) and other fobs/access cards that could cause Radio Frequency Interference (RFI). Retest the system.
5. If symptoms persist, and especially if other TPMS or security codes are present, the diagnosis points towards the Remote Control Door Lock Receiver (RCDLR) per TSB #16-NA-396.
6. Advanced diagnostics with a professional scan tool (GDS2) are needed to check for specific symptom bytes (e.g., C0755 39 for internal malfunction) and to check communication with the RCDLR before ordering a replacement.
7. If the RCDLR is determined to be faulty, it will need to be replaced and programmed by a qualified technician with access to GM's Service Programming System (SPS).

Scan Tool Commands That Help

• GDS2 (GM Global Diagnostic System 2): Module Setup / RCDLR Setup — This function is required after installing a new RCDLR to integrate it with the vehicle's systems before programming keys or TPMS sensors.
• GDS2 / Tech2Win: Theft Deterrent System Learn — After RCDLR replacement, a 10 or 30-minute relearn procedure must be performed to sync the new module with the vehicle's immobilizer system.
• GDS2 / Tech2Win: Tire Pressure Indicator Sensor Learn — After replacing the RCDLR or any TPMS sensor, this procedure must be run to teach the module the unique ID of each sensor in its specific location on the vehicle.
• SPS (Service Programming System): Program ECU / Replace and Program ECU — This is the software used to load the correct firmware onto the new RCDLR module. It requires an online subscription with GM. It is also now recommended to try reprogramming an existing module before replacement to see if a software update fixes the issue.

Wiring & Ground Locations

• RCDLR Module — On the Buick Envision, the RCDLR is located behind the passenger side lower center console panel.. This is the central receiving unit for both TPMS and key fob signals. Physical access is required for replacement, and checking its connector for corrosion or damage is a key diagnostic step.
• G103 — Located on the cowl in the left rear of the engine compartment, above the brake booster.. This is a major ground point that provides the ground path for the RCDLR, BCM, and Instrument Panel Cluster (IPC). A loose or corroded G103 can cause a wide range of difficult-to-diagnose electrical issues, including symptoms related to code C0755.
• RCDLR Antenna — On similar GM platforms, the antenna is often integrated into the rear quarter glass or headliner area to ensure a clear reception path.. Damage to the antenna or its connection to the RCDLR can cause weak signal reception, leading to intermittent TPMS and key fob issues.
