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

.

1.

Switch the ECM from normal mode to check mode using the Techstream

.

2.

Perform a simulation test.

3.
