ATEQ TPMS Reset Procedure

NOTE: Unless otherwise stated, on most tire pressure sensor equipped vehicles, low tire pressure indicator lights and messages can be cleared by inflating tires to the specified pressure and driving at least 25 mph or more for a few minutes. A sensor activation tool (TPMS3) can be used in place of driving.

NOTE: When the wheels have been rotated, or a tire pressure sensor or EGM/LGM has been replaced, retrain tire pressure sensors.

NOTE: The DIC will display the "SERVICE TIRE MONITOR" message if one or more of the tire pressure sensors has malfunctioned or if all of the sensors have not been programmed successfully. If, after the relearn procedure, the warning indicators are still on, there is a problem in the TPMS.

NOTE: If this procedure is performed following replacement and reprogramming of the Liftgate Module (LGM), DIC may display a low tire pressure fault and all tire pressures read 0 psi. If this problem occurs, see appropriate manufacturer service information.

NOTE: The TPMS will cancel the learn mode if more than 2 minutes have passed and no sensors have been learned, or if the system has been in learn mode for more than 5 minutes. If the learn mode is canceled before any sensor has been learned, the EGM/LGM will remember all current sensor IDs and their locations. As soon as the first sensor ID code is learned, all other IDs are erased from the EGM/LGM's memory. On models that display the individual tire pressure on DIC, updated tire pressures will not be displayed until EGM/LGM receives 2 more valid transmissions from each sensor.

NOTE: Before proceeding with the steps below, ensure that no other sensor learn procedure is being performed simultaneously, or that tire pressures are not being adjusted on a TPM equipped vehicle within close proximity.

Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
Turn ignition ON with engine OFF. Apply parking brake.
NOTE: If Learn Mode cannot be enabled, TPMS is not enabled in EGM/LGM. See appropriate manufacturer service information.
To enable Learn Mode, turn headlight switch from OFF to parking lamps 4 times within 4 seconds. A double horn chirp will sound and the low tire pressure indicator will begin to flash to indicate the learn mode has been enabled.
Starting with left front tire, hold the TPMS3 against the side wall of the tire, within 3 inches of the valve stem. Press TEST button on the TPMS3 until a horn chirp sounds.
After horn chirp has sounded, proceed to the next 3 sensors in the following order: right front, right rear and left rear.
After left rear sensor has been learned, turn ignition switch to OFF position to exit Learn Mode.
Test drive the vehicle above 25 mph for at least 2 minutes before viewing tire pressures on DIC.
