Defect Code 40

Defect Code 40:

*D* Defect code memory: Data transfer to instrument cluster faulty:

Explanation: This defect code is stored when the data transfer between the EKM and instrument cluster is faulty.

Troubleshooting:

- If the defect code 41 or 42 is additionally stored, first rectify these defects in accordance with the instructions displayed on the screen.
- Check data link between EKM connector green Pin 17 and instrument cluster Pin 13. (Wire resistance < 1 Ohm? Contacts of connector OK? Short on wire?)
- If wire is OK: Connect EKM and instrument cluster. Clear defect code memory. Then wait for at least 60 s to allow for sufficiently long data transfer between EKM and the instrument cluster. If the defect code is stored once again, as a check, renew electronic module of the instrument cluster. Observe information on test run.
