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: If a tire pressure sensor or the Remote Control Door Lock Receiver (RCDLR) is replaced, or if wheels have been rotated, tire pressure sensor must be retrained.

NOTE: When the tire pressure warning light illuminates and warning message appears on DIC, immediately check air pressure of all tires and adjust to the specified pressure. If warning indicators are still on or display shows dashes instead of a value, there is a problem in the TPMS. See appropriate manufacturer service information.

NOTE: Under the following conditions, the TPMS may not function properly:

If one or more of the tire pressure sensors are missing or inoperable.
A compact spare tire is used.

NOTE: If a tire pressure sensor or the Remote Control Door Lock Receiver (RCDLR) is replaced, or if wheels have been rotated, tire pressure sensor must be retrained.

NOTE: The relearn procedure must be completed within 15 minutes from when the vehicle is stationary after being driven at 20 mph (32 km/h), or greater, for 10 seconds.

NOTE: The learn mode will cancel if the ignition is cycled to OFF or if more than 2 minutes has elapsed for any sensor that has not been learned. If the learn mode is cancelled before the first sensor is learned, the original sensor IDs will be maintained. If the learn mode is canceled after the first sensor is learned, the following will occur:

All stored sensor IDs will be invalidated in the RCDLR memory.
If equipped, the DIC will display dashes instead of tire pressures.
DTC C0775 will be set.

These conditions will now require the learn procedure to be repeated for the system to function properly.

IMPORTANT: Ensure that no other learn procedure is being performed simultaneously or that tire pressures are not being adjusted on another TPM equipped vehicle within close proximity. 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.

Turn ignition switch to ACC position. Apply parking brake.
Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
To enable Learn Mode:
- On vehicles equipped with keyless entry, simultaneously press the keyless entry transmitters lock and unlock buttons until a double horn chirp sounds indicating the Learn Mode has been enabled. The left front turn signal will also be illuminated.
- On vehicles not equipped with keyless entry, press and release the driver information center (DIC) INFO button until the TIRE LEARN message appears on the DIC display. Press and hold the SET/RESET button until a double horn chirp sounds indicating the Learn Mode has been enabled. The left front turn signal will also be illuminated.
Ignition ON.
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.
