Tire Monitoring System: Service and Repair

Tire pressure monitoring system (TPMS)

To reset a warning it is easiest to stop the vehicle and fill air in the tire where the air pressure is low. In order for the warning to reset air has to be filled so that the air pressure reaches a level that corresponds to at least 95% of the recommended air pressure, and then drive the vehicle faster than 40 km/h (25 mph) for more than 10 minutes, accumulated time.
If the customer has come to the workshop, the warning can also be reset by filling air in the tire where the air pressure is low (up to min. 95% of the recommended air pressure) and then the sensor is activated with the special tool for activating the tire pressure sensor.
When air is filled and the pressure changes, the sensor immediately sends a signal to Upper Electronic Module (UEM). If the ignition is on, the warning is reset immediately.

Note! Only applies to USA/CDN. A warning lamp also lights in the Driver information module (DIM) at the same time as the warning message.
