On-Board Diagnostics
WARNING: This page is about a different variant/trim than selected.
If the ASC-ECU detects any problem in the CAN communication line or the ECUs, which the ASC-ECU is communicating with, it stores a diagnostic trouble code. The DTCs can be confirmed by connecting scan tool MB991958 (M.U.T.-III sub assembly.) The stored DTCs are not erased even after the ignition switch has been turned to the LOCK (OFF) position, or the battery has been disconnected. The DTCs can be erased by operating scan tool MB991958 (M.U.T.-III sub assembly.)
