Diagnostic Trouble Code (DTC) table

DTCs VAG 00466 to 65535

NOTE:

The table below includes all the malfunctions that can be detected by Airbag Control Module -J234-, listed according to their DTC numbers. If the printer on VAG 1551 Scan tool is switched on, the malfunctions can be printed out together with their 5-digit DTCs. When a malfunction occurs, the airbag system warning lamp will light up and remain lit until the malfunction is repaired and the DTC memory has been erased. If a malfunction only occurs occasionally or if the DTC memory is not erased after a malfunction has been repaired, the malfunction will be shown as a sporadic DTC. Such malfunctions are identified by the letters "/SP" on the right of the VAG 1551 display and will cause the warning lamp to light up continuously. If a component is indicated as being faulty, always test for open circuits and short circuits in the wiring to the component (using the wiring diagram) as well as testing the component itself.
