Check for intermittent problems

Check for intermittent problems

Hand–held tester only:

by putting the vehicle’s ecm in the check mode, the 1 trip detection logic is possible instead of the 2 trip detection logic, and the sensitivity to detect faults is increased. This makes it easier to detect intermittent problems.

  1. Clear the dtcs .
  2.  set the check mode .
  3.  perform a simulation test .
  4.  check the connector and terminal .
  5.  wiggle the harness and connector
