​

CHECK FOR INTERMITTENT PROBLEMS
HINT:
For use of the intelligent tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with an intelligent tester when the ECM is in check mode. In check mode, the ECM uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detection logic.

  1. Clear DTCs (Click here).

  2. Switch the ECM from normal mode to check mode using an intelligent tester (Click here).

  3. Perform a simulation test (Click here).

  4. Check and wiggle the harness(es), connector(s) and terminal(s) (Click here).
