How do I program my new TPMS sensor on my GM?
Most GM vehicles with a compatible TPMS sensor will relearn automatically when you drive after installation. If auto-relearn isn’t available or the indicator stays on, you may need to use the vehicle’s TPMS relearn menu or a supported programming tool to register the new sensor IDs. Procedures vary by model and year, so consult your owner’s manual or GM service bulletins for model-specific steps.
This article explains how to determine your sensor type, the standard auto relearn method for GM vehicles, and the manual or tool-based alternatives you may need. It covers differences by model year and explains when professional programming might be required.
Understanding GM TPMS and relearn methods
GM uses TPMS sensors in each wheel to report tire pressure. Depending on your model, the system can relearn sensors automatically during normal driving or require a manual procedure using the instrument cluster or a professional scan tool.
Automatic relearn by driving (drive-to-learn)
Before you use the drive-to-learn method, ensure the sensors are installed correctly and tires are inflated to the recommended pressures. The steps below describe the typical auto relearn process for GM vehicles that support it.
- Ensure the new sensor is properly installed in the wheel with a fresh valve stem seal and valve core; torque lug nuts to spec and reinstall the wheel if removed.
- Inflate the tire to the vehicle's recommended cold pressure as listed on the door data sticker or manual.
- Drive the vehicle at a steady speed between about 30 and 50 mph (50–80 km/h) for roughly 10–20 minutes, avoiding abrupt stops or rapid steering changes.
- If the TPMS light stops flashing and then goes out, the relearn has completed. If it remains on, proceed with a manual relearn or tool-based step.
After completing an auto relearn, you may need to drive for a short additional cycle to ensure the system stabilizes. If your vehicle doesn't show the light going out, try another 10–15 minute driving cycle or proceed to manual relearn steps.
Manual relearn or tool-based relearn (when auto relearn isn’t available)
If your GM model requires manual relearn or you’re using non-automatic sensors, use one of the following approaches. The exact prompts vary by model and year, so refer to your owner's manual or service tool instructions.
- Vehicle-based relearn in the cluster or driver information center (DIC): Navigate to Settings or Vehicle applications, select TPMS or Learn Sensors, and follow the on-screen prompts to begin the relearn. You'll typically be instructed to inflate each tire to the correct pressure and drive or to hold a learn sequence after starting the engine.
- OBD/check-tool relearn: Connect a supported TPMS programming tool or a professional scan tool (Autel MaxiTPMS, Snap-On, etc.) that supports GM protocols, select "Learn" or "Relearn Sensors," and enter or read the sensor IDs as prompted. The tool will write the IDs to the vehicle’s TPMS control module and may require you to drive afterward.
- Dealer/independent shop programming: If you have programmable sensors (or the vehicle requires sensor IDs to be loaded via GM’s vehicle programming system), a GM dealer or tire shop with the proper tools (GM Tech 2, GM GDS2, or equivalent) can program the sensors and perform the relearn.
After manual or tool-based relearn, drive the vehicle for a short test cycle (about 10–20 minutes at highway speeds) to confirm the system is stable and the TPMS light remains off.
Vehicle-specific notes
GM model-year and sensor-type caveats
Some GM models use non-programmable sensors that only require the vehicle to relearn the IDs from the ECU, while others require manual relearn or sensor ID programming through a tool. High-end GM trucks and certain SUVs may need dealer-level programming for new sensors to work with the tire-pressure monitoring system. Always check your owner's manual for the exact procedure and the required tool. If you’ve replaced wheels with aftermarket tires, the vehicle may require recalibration or a reflash.
Summary
Relearning a new TPMS sensor on a GM vehicle typically starts with an auto relearn via driving, which is the simplest path. If auto relearn isn’t available or doesn’t complete, use the vehicle’s TPMS relearn menu or a supported programming tool to register the new sensor IDs, and when needed, seek dealer or professional programming. Ensure tires are correctly inflated, then test-drive to confirm the system reports accurate pressures.
