how do I reset the tire pressure light on my Cadillac Escalade T1XX (2021-Present)

Symptoms

• Tire pressure light illuminated on the dashboard
• Possible warning message displayed on the driver information center
• Inconsistent tire pressure readings when checked manually
• No change in tire pressure light after adjusting tire pressures

Diagnostic Steps

1. Verify that all tires, including the spare, are inflated to the recommended pressure levels.
2. Check for any visible damage or leaks in the tires.
3. Inspect the TPMS sensors for proper functioning and battery life.
4. Use an OBD-II scanner to check for any TPMS-related error codes.

Solution

1. Preparation

• Ensure all tires are at the correct pressure. Refer to the door jamb sticker for the recommended PSI.
• Turn the ignition key to the "On" position without starting the engine.

2. Reset TPMS

1. Locate the TPMS reset button, typically found beneath the steering column or in the glove compartment.
2. Press and hold the TPMS reset button until the tire pressure light blinks three times, then release it.
3. Start the vehicle and allow it to run for about 20 minutes to ensure the TPMS recalibrates.

3. Verify Tire Pressure

• After resetting, check the tire pressures again to ensure they are all at the specified levels.
• If the light remains on, repeat the reset procedure or consult a professional for further diagnostics.
