The system is permanently operational and is not operated actively by the driver. Every time the CAN-B wakes up the TPM [RDK] control unit (N88) is reactivated and it starts to send messages to the instrument cluster (A1). In the event of any changes to air pressure by the driver, or if wheels are changed around or a tire replaced the determination of new tire inflation pressures is performed automatically in the TPM [RDK] control unit when it detects the inflation process.
The following procedure must be followed for activation:
Correct the air pressure in each wheel;
Switch on the ignition (circuit 15 "ON").
