Defect Code 2

Defect Code 2:

*D* Defect code memory: I-Bus detect:

Explanation: An open line can be detected; a permanent defect can only be sensed by the EKM (I-bus is blocked in the case of permanent defect) since, in this case, the MID can no longer send its error message.

Troubleshooting: Check I-bus link and repair if necessary. From MID connector X 501 Pin 17 via rear connector I-bus to EKM connector brown Pin 1. If link OK and detect not rectified, continue troubleshooting with information provided in diagnostic program/EKM troubleshooting.
