CHECK FOR INTERMITTENT PROBLEMS
HINT:
Troubleshoot malfunctions with the ECM in 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.
