CHECK FOR INTERMITTENT PROBLEMS
HINT:
Intelligent Tester II only:
Inspect the vehicle’s ECU using check mode. Intermittent prob-
lems are easier to detect when the Intelligent Tester II is in
check mode. In check mode, the Intelligent Tester II uses 1 trip
detection logic, which has a higher sensitivity to malfunctions
than normal mode (default), which uses 2 trip detection logic.
