Volkswagen Workshop Service and Repair Manuals

Fault table   Note t  The following table lists all the faults, with the corresponding 5-digit code numbers, that can be recognized by the airbag control unit -J234- and displayed or printed out by the -V.A.G 1551- or -VAS 5051-. t  Fault codes appear only on print-out. t  Some of the fault messages listed are only displayed on the -VAS 5051-. With the -V.A.G 1551-, only the fault code will be printed in these cases. t  The particular vehicle equipment in each case will determine which faults are possible. t  Before replacing a component shown as faulty, check wiring and connections to the component as well as earth connections according to current flow diagram. t  Check all relay plate connections are seated securely. t  When repair has been carried out, the fault memory must always be interrogated again with the fault reader -V.A.G 1551- or -VAS 5051- and erased. t  In addition, the fault type may also appear in the fault table.
