Fault table of control unit for convenience system with LIN databus cable
Fault table of control unit for convenience system with LIN databus cable
  Note
t  Below is a list of all possible faults detected by the central control unit for convenience system -J393- and displayed on -V.A.G 1552 -, arranged according to their 5-digit fault code.
t  SAE code, may be displayed on the right next to the fault number (e.g. 4214), ignore.
t  If “Info in literature” appears in the display of the vehicle system tester, look for the text required in the fault table under the fault code.
t  After repair always interrogate the fault memory using vehicle system tester -V.A.G 1552- and erase the memory.
t  If parts are output as faulty: First check all cables and connectors to these components as well as the earth connections according to the Current Flow Diagram. Then check whether all plug connections are properly plugged into the relay plate. Replace the component only if this test does not reveal any fault. This applies in particular if faults are shown as “sporadic” (SP).
