Learn Mode Cancellation

The learn mode will cancel if more than 2 minutes have passed and no sensor have been learned, or if more than 5 minutes has passed for the entire procedure. If the learn mode is canceled before any Ids are learned, the BCM will remember all previously stored Ids and their locations. As soon as the BCM learns the first Id, all other Ids are erased from the BCM's memory.

IMPORTANT: Before proceeding with the step below, ensure that no other sensor learn procedure is being performed simultaneously, or that tire pressures are not being adjusted on another TPM equipped vehicle within close proximity.
  1. Turn ON the ignition, with the engine OFF.
  2. Apply the parking brake.
    3. IMPORTANT: If the TPM learn mode cannot be enabled, ensure the TPM system is enabled in the BCM. Refer to Tire Pressure Monitor System Configuration .
  3. Turn the exterior lamp switch from OFF to parking lamps 4 times within 4 seconds. A horn chirp will sound and the low tire pressure indicator will begin to flash indicating the learn mode has been enabled.
    4. CAUTION: Over inflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure do not exceed the maximum inflation pressure as noted on the tire sidewall.
    IMPORTANT: If a horn chirp does not sound after 35 seconds for any of the 4 sensors, turn the ignition OFF to exit the learn mode and repeat the procedure from step 1.
  4. Starting with the left front tire, hold the antenna of the TPM 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, or increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached.
  5. After the horn chirp has sounded, proceed as in step 4 for the next 3 sensors in the following order:
    1. Right front
    2. Right rear
    3. Left rear
  6. After the LR sensor has been learned, turn OFF the ignition to exit the learn mode.
  7. After the learn mode has been exited, adjust all tire pressures to the recommended psi. Refer to Label - Vehicle Certification, Tire Place Card, Anti-Theft and Service Parts ID in General Information.
