For second-generation Chevrolet Express vans:

1. Set the parking brake
2. Turn the ignition to the “ON” position without starting the engine
3. Press the trip odometer reset stem until “RELEARN TIRE POSITIONS” appears on the Driver Information Center (DIC)
4. Press and hold the trip odometer reset stem until the horn chirps
5. Starting with the left front tire, use a TPMS relearn tool to activate the TPMS sensor
6. Wait for a horn chirp before moving to the right front tire
7. Repeat the process for the right rear and left rear tires
8. After the last tire, the horn will chirp twice to indicate the relearn process is complete

Third Generation (2016-Present)

For the latest generation of Chevrolet Express:

1. Inflate all tires to the recommended pressure
2. Turn the key to “ON” without starting the vehicle
3. Using the right keypad on the steering wheel, navigate to the “INFO” menu
4. Scroll to the Tire Pressure screen
5. Hold the “OK” button for 5 seconds
6. The van will beep twice, indicating you’ve entered TPMS relearn mode
7. Use a TPMS diagnostic tool to relearn each tire sensor, starting from the front left wheel
8. The horn will sound twice after the last tire pressure sensor is relearned, indicating completion

Using a TPMS Relearn Tool

For many Chevrolet Express models, especially those from 2008 onwards, you’ll need a TPMS relearn tool to complete the process. Here’s how to use it:

1. Position the tool near the valve stem of the tire
2. Press the activate button on the tool
3. Wait for a chirp from the vehicle, indicating the sensor has been recognized
4. Move to the next tire and repeat the process
5. Continue until all four tires have been relearned

It’s important to note that the order of relearning typically starts with the driver’s side front tire and moves clockwise around the vehicle.
