Diagnostic Trouble Code (DTC) table

NOTE:

The following table lists all the malfunctions, with the corresponding 5-digit code numbers, that can be recognized by the Airbag Control Module -J234- and printed out by the V.A.G 1551.
The most current coding for airbags can only be found using the VAS 5051. To get the control module coding list through Guided Fault Finding press the "Go to" button, and select "Function/Component selection". Follow the prompts through to Functions - Code Airbag Control Module.
DTC's appear only on print-out.
Some of the mentioned DTC texts are only displayed on the VAS 5051. On the V.A.G 1551, only the DTC will be printed in this case.
The possible malfunctions are dependant on the respective vehicle equipment.
Before replacing a component shown as malfunctioning, check wiring and connections to the component as well as Ground connections according to wiring diagram.
Check all relay plate connections are seated securely.
After completing repairs, the DTC memory must always be re-checked and erased using the V.A.G 1551 scan tool.
In addition, the malfunction type may also appear in the DTC table.
