Tire Pressure Sensor Relearn
WARNING:
If not utilizing a scan tool to initiate the relearn procedure, stray signals from other TPM equipped vehicles just driving by can be inadvertently learned. If any random horn chirps are heard from the vehicle while performing the learn procedure, most likely a stray sensor has been learned and the procedure will need to be cancelled and repeated. Under these circumstances, performing the TPM Learn Procedure away from other vehicles would be highly recommended. In the event a particular sensor activation does not cause the horn to chirp, it may be necessary to rotate the wheel valve stem to a different position due to the sensor signal is being blocked by another component. Before proceeding with the steps below, verify the following: No other sensor learn procedure is being performed simultaneously within close proximity. Tire pressures are not being adjusted on another TPM equipped vehicle within close proximity. Park Brake Switch input parameters are functioning correctly.
- Apply the parking brake (Manual Transmission only).
- Turn ON the ignition, with the engine OFF.
- Using a scan tool or the DIC select Tire Pressure Sensor Relearn. A double horn chirp will sound and the left front turn signal will be illuminated.
- Starting with the left front tire, learn the tire pressure using one of the following methods:
- Method 1: Hold the antenna of the TPM sensor activation tool against the tire sidewall close to the wheel rim at the valve stem location then press and release the activate button and wait for a horn chirp.
- Method 2: Increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached.
- After the horn chirp has sounded, repeat procedure for the remaining 3 sensors in the following order: Right front, Right rear, Left rear.
- After the LR sensor has been learned, a double horn chirp will sound indicating all sensors have been learned.
- Turn OFF the ignition to exit the learn mode.
- After the learn mode has been exited, adjust all tires to the recommended pressures.
