COMMENT
The fail-safe function is probably canceling auto-
cruise control system. In this case, checking the auto-
cruise control system, MFI system, A/T system and
CAN bus line system for diagnostic trouble codes. The
scan tool MB991958 can also be used to check if the
circuits of each input switch are normal or not by
checking the input switch codes.
