Defect Code 1

*D* Defect code memory: 1 Central indicator lamp

Explanation:
This detect code is stored when the ZHL has failed or lights for no apparent reason (intermittently or continuously).

Attention:
Defect code is also set when no ZHL is installed.

This means that this defect code is always set in vehicle which are not equipped with a check module. The defect can be ignored in this case.

Possible cause:
ZHL defective; wire from BC to ZHL defective; instrument cluster defective.

Troubleshooting:
Check wire and repair if necessary: From black BC connector Pin 6 to instrument cluster connector X 17 Pin 26.

If wire OK., check instrument cluster/ZHL and repair if necessary.
