Was bedeutet der Fehlercode?
The climate control module (CCM) gets no response from the seat heating module (SHM) in the right front seat. The module sends its status to the control module over LIN bus 2, and when the reply is missing the control module cannot control the heat. The cause may be a lost voltage supply or ground, a fault in the bus to the right front seat, or an internal fault in the module.
Mögliche Ursachen
- Lost voltage supply or a problem with the ground connection
- Fault in LIN bus 2 between the control module and the right front seat heating, or in the connector at the climate unit
- Internal fault in the seat heating module (SHM)
- Internal fault in the right front seat heating module (SHMR)
Was Sie tun können
- 1Check that the fuses are intact, especially the fuse for the seat heating
- 2Check that the connectors to the seat heating and to the climate unit are firmly seated and free from oxidation
- 3Use a multimeter to check that the supply to the seat heating is present with the ignition on, and that the ground wire has contact with ground (the body)
- 4Read off and clear the fault code, then road test the car to see whether it returns
- 5With diagnostic equipment, activate the right front seat heating and check that it starts. If it does not, and the connectors are sound, the bus needs checking
- 6If the fault remains after these checks, have a workshop check LIN bus 2 between the climate control module and the seat heating
Symptome, die Sie bemerken können2
- The electric heating in the front seat does not work
