Checking Diagnostic Trouble Codes In The ABS System.
- Fault-trace diagnostic trouble codes (DTCs) stored in the ABS system.

^ Then continue with test step below.

Checking Diagnostic Trouble Codes In The Combined Instrument Panel
- Fault-trace diagnostic trouble codes stored in the VDO combined instrument panel.

^ Then continue with test step below.





Checking Cables And Terminals
- Fault-trace combined instrument panel and vehicle speed sensor (VSS) circuit for intermittent faults and an intermittent short-circuit to supply voltage.
- Check control module and combined instrument panel connectors and connector 24/13 for loose connections.
- Check cable between the combined instrument panel terminal A7 and engine control module (ECM) # B18 for an intermittent open-circuit and intermittent short-circuit to ground.

Fault-tracing Information
For intermittent faults fault-tracing is not followed by a verification because the fault is not present at this moment.

- Do you want to repeat fault-tracing?

Yes:
^ Return to Checking Diagnostic Trouble Codes In The ABS System. section above.

No:
^ Operation done.
