How to Perform TPMS Relearn on a LYRIQ: Auto, OBD, and Stationary Procedures

Understanding the LYRIQ TPMS System

The LYRIQ uses a direct TPMS system that monitors tire pressure via individual wheel sensors. Unlike older GM models, the LYRIQ employs a 433MHz frequency and uses a pre-programmed sensor that must be learned into the vehicle’s BCM (Body Control Module) after installation. The system supports three relearn methods, but not all are equally effective on every LYRIQ model year.

TPMS Relearn Methods for LYRIQ

1. Automatic Relearn (Drive-Based)

This method requires no tools and works by driving the vehicle under specific conditions.

Procedure:

• Ensure all tires are inflated to the recommended pressure (check driver’s door jamb sticker).
• Start the engine and drive the vehicle above 20 mph (32 km/h) continuously for 10–15 minutes.
• The system will automatically detect the sensor IDs as the vehicle moves.
• The TPMS warning light should turn off after a successful relearn.

When it works: This method usually succeeds if you have replaced a sensor with the same part number and the sensor is transmitting. However, on some LYRIQ models, the automatic relearn may take longer or fail if the old sensor’s data is still stored.

2. OBD Relearn (Tool-Based)

This is the most reliable method for the LYRIQ, especially if you’re installing new sensors or switching between winter and summer tires.

Tools needed:

• A TPMS programming tool that supports GM/LYRIQ (e.g., Autel TS508, Bartec Tech400, or similar).
• A compatible OBD2 adapter.

Procedure:

• Turn the ignition ON (engine off or in accessory mode).
• Connect your TPMS tool to the OBD2 port (located under the driver’s dash).
• Select “Relearn” or “Program” on the tool and follow the on-screen prompts.
• The tool will send a command to the BCM to enter relearn mode.
• Activate each sensor in the correct order: LF → RF → RR → LR (clockwise, starting at the driver’s front tire).
• Use the tool to trigger each sensor (some tools require a magnet, others use RF activation).
• After the last sensor is learned, the tool will confirm the procedure.
• Verify by checking the TPMS light on the dashboard—it should go solid briefly, then turn off.

Note: The BH-Sens BL-ST-097 sensor (SKU: BL-ST-097) is pre-programmed to match OE frequencies and IDs, so it will work seamlessly with OBD relearn tools. No additional programming of the sensor itself is needed.

3. Stationary Relearn (Magnet-Based)

This is an older method that may work on some LYRIQ models, but it is not guaranteed on all years.

Tools needed: A strong TPMS magnet (at least 10 lbs of pull force).

Procedure:

• Turn the ignition ON.
• Navigate to the “Tire Pressure” menu on the infotainment screen.
• Select “Relearn” or “Sensor Learning” (if available).
• The horn will chirp twice to indicate the system is in learn mode.
• Place the magnet directly over the valve stem of the LF tire. Wait for the horn to chirp once.
• Repeat for RF, RR, and LR in that order.
• After the LR sensor is learned, the horn will chirp twice to confirm completion.
• Turn off the ignition.

Limitations: Many LYRIQ models have discontinued the magnet-based relearn in favor of OBD or automatic methods. If the infotainment screen does not show a “Relearn” option, skip this method.

TPMS Sensor Specifications for LYRIQ

The BL-ST-097 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Buick, Cadillac, Chevrolet, Nevo | OE# 13530661, 13533166, 13538565 sensor from BH-Sens (Baolong Technology) is a direct-fit replacement for the LYRIQ. It is pre-programmed to match the vehicle’s original sensor IDs, so you only need to perform a relearn—not a full sensor programming step.

Common Issues and Troubleshooting

• Relearn fails after sensor replacement: Ensure the sensor battery is not dead (new sensors typically have a 5–7 year lifespan). Also verify the sensor is transmitting by using a TPMS tool to read its signal.
• Warning light stays on after driving: The automatic relearn may not have completed. Try the OBD method.
• Incorrect tire position readings: This happens if the sensors were learned in the wrong order. Repeat the relearn procedure, paying attention to the sequence.

Recommended Part

For a hassle-free replacement, use the BL-ST-097 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Buick, Cadillac, Chevrolet, Nevo | OE# 13530661, 13533166, 13538565. It is a pre-programmed 433MHz clamp-in sensor that fits the LYRIQ and other GM vehicles. No additional programming tool is required for the sensor itself—just a relearn tool for the vehicle.

FAQ

Can I use a universal TPMS sensor on a LYRIQ?

Yes, but you must ensure the sensor is 433MHz and pre-programmed to match GM protocols. The BH-Sens BL-ST-097 is a direct-fit option. Do not use universal sensors that require manual frequency settings unless you have a programming tool that supports them.

How long does a LYRIQ TPMS relearn take?

The OBD relearn takes about 5–10 minutes, including activating all four sensors. The automatic drive-based relearn takes 10–15 minutes of driving. The stationary magnet method takes roughly 5 minutes but may not work on all models.

Do I need to reset the TPMS after tire rotation?

Yes. Tire rotation changes the sensor positions relative to the vehicle. The BCM needs to know which sensor is at which corner. Perform a relearn after every tire rotation to ensure accurate pressure readings.

What if my LYRIQ does not enter relearn mode?

Check that the ignition is in the correct mode (ON, not ACC). If using the OBD method, ensure your tool is compatible with GM vehicles. If using the automatic method, drive for at least 20 minutes at a steady speed above 20 mph. If none work, consult the vehicle’s owner manual or a professional technician.
