Auto Location

Parking Mode: The system enters 'Parking Mode' after the vehicle speed has been less than 20 km/h (12.5 mph) (including stationary) for 15 minutes. In parking mode the tire pressure sensors transmit a coded signal to the Tire Pressure Monitoring System Control Module (TPMSCM) once every 6 hours. If the tire pressure decreases by more than 7 kPa (1 psi, 0.07 bar), the sensor transmits more often to indicate tire pressure lost.

Auto Location: For the front and rear tires, the requirement for pressure targets and thresholds can be different. The Tire Pressure Monitoring System (TPMS) can automatically identify the locations of the tires on the vehicle, and assign received tire pressure sensor identifications to a specific position on the vehicle. For example, front left, front right, rear left or rear right.

The TPMS can automatically learn the tire pressure sensor identification and position of tires on the vehicle if the sensors or their positions are changed. The process of locating the tire pressure sensors is known as 'Auto Location' and requires no manual intervention. The TPMS learns the location of the 4 sensors in the wheels by combining Radio Frequency (RF) transmissions with data from the Anti-lock Braking System (ABS) control module.

NOTE: An Anti-lock Braking System (ABS) fault does not cause the Tire Pressure Monitoring System (TPMS) to stop operating. However, if an ABS fault persists then the auto location may fail and a TPMS warning may also display in the Instrument Cluster (IC).

The auto location process is ready to start when the vehicle is in parking mode. The process needs the vehicle to be driven at speeds of more than 20 km/h (12.5 mph) for 10 minutes. During the auto location processing period, the tire pressure sensors transmit at regular intervals, once every 15 seconds. After auto location is complete, the tire pressure sensors transmit once every 60 seconds (also when a tire pressure change is sensed). When the vehicle speed remains below 20 km/h (12.5 mph) (including stationary) for more than 15 minutes, the vehicle returns to parking mode and the auto location process is ready to start again.

NOTE: When you replace the tire pressure sensors or tires, make sure that the vehicle is in 'Parking Mode' and perform the 'Auto Location' process. This will make sure the Tire Pressure Monitoring System (TPMS) learns the system change.
