About Trouble Codes
Diagnostic Trouble Code (DTC) tableNotes:
- The following table lists all DTC's, with corresponding 5-digit code numbers, that can be recognized by the Airbag Control Module -J234- and printed out by the VAG 1551 Scan Tool.
- DTC codes appear only on the print-out
- Some DTC texts (descriptions) will show only if the VAS 5051 is used. With V.A.G 1551, these DTC's will show only the DTC and not the descriptive text.
- The possible DTC's are dependant on the current configuration of the vehicle.
- Before replacing a component shown as inoperative, check all related wiring and connections to the component as well as Ground (GND) connections according to wiring diagram.
- Ensure all relays are seated securely.
- After repairs, DTC memory must be checked again with the VAG 1551 or VAS 5051 Scan Tool and erased.
- The DTC type may also appear in the DTC table.
