Configuration Of The TPMS System

The TPMS system is self-learning. This means that when the vehicle is driven and the sensors transmit messages, the Central electronic module (CEM) receives and registers the ID numbers that the sensors transmitted.

After a process of elimination during a certain period, the Central electronic module (CEM) then decides that the sensors with the four most frequently received ID numbers belong to the vehicle.

To check the communication chain from sensor to Central Electronic Module (CEM), the tests can be activated from VIDA:

• WS-test (Workshop test). The procedure is used to check that the Central Electronic Module (CEM) receives four unique sensor IDs when these sensors are activated one at a time with the diagnostic tool and thus check that the system works as intended. An example of this is when a sensor has needed to be replaced or if the Central Electronic Module (CEM) has been replaced.

  The workshop test is completed with OK as a result when four sensor IDs have been received.
