Self-diagnosis for the driver's side seat adjustment
Functional description for the self-diagnosis
It is an independent system and has the self-diagnosis address word 36 "Seat adjustment driver's side". The seat adjustment control unit (J136) is located under the driver's seat and is connected to the convenience system via the CAN data bus. It is equipped with a fault memory. The connector for the self-diagnosis is located in the centre console. The control unit detects faults in the system and stores them in a permanent memory. To commence fault finding, initiate self-diagnosis and retrieve the stored information with the fault reader V.A.G 1551. System tester V.A.G 1552 may also be used. The fault information displayed is used to refer to a fault table with notes on the possible causes for directed repair measures. Faults which can be attributed to a temporary open circuit in the wiring or a loose contact, will also be stored. These faults will be displayed as sporadic faults "SP". The individual operating functions are described in the following description. |
