Monitor Description
While the engine is being cranked, the battery positive voltage is applied to terminal STA of the ECM.
If the ECM detects the starter control signal (STA) while the vehicle is being driven, it will conclude that there is a fault in the starter control circuit. The ECM will illuminate the MIL and set a DTC.
This monitor runs when the vehicle is driven at 20 km/h (12 mph) for over 20 seconds.
