Was a fault detected?
Yes - Checking the brake control module
No - Checking communication with the brake control module (BCM)
-------------------------------------------------
Checking communication with the brake control module (BCM)
Hint: The CAN communication with the control module is probably OK if the control module ID can be read off. In that case the fault is probably intermittent and will then be more difficult to trace.
- Try to communicate with the brake control module (BCM) by reading off the control module ID
- Click on the symbol for VCT2000 to begin reading off

Checking the brake control module (BCM)
Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reconnect the connectors. Reinstall the components
- Ignition on for at least 10 seconds.
Read off the control module ID from the brake control module (BCM) by clicking on the VCT2000 symbol.
Could the control module ID be read off?
Yes - Procedure complete
No - Fault-tracing information
-------------------------------------------------
Fault-tracing information
Information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit Fault-tracing
No - Attempt New Test
