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.
