Checking the Ground Points (DIM)
Checking the ground terminals
Checking the ground terminals
- Ignition off.
- Control unit disconnected.
- Switch off all battery loadings such as entrance lighting and radio.
Connect an ohmmeter between the battery negative lead and test box 14.

The ohmmeter should display approximately 0.
OK - DONE
Not OK - contact resistance and oxidation.

Fault-tracing 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 - FAULT-TRACING FAILED
No - Attempt New Test
