CHECK FOR INTERMITTENT PROBLEMS

HINT:

Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with the Techstream 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.

Clear the DTCs (See page ).
Switch the ECM from normal mode to check mode using the Techstream (See page ).
Perform a simulation test.
Check and wiggle the harness(es), connector(s) and terminal(s).
