Circuit Description

Starter control system is controlled by the Engine Control Module (ECM). The ECM monitors starter switch signal ("START" position) and MODE switch (park or neutral) signal. ECM is operated by the ignition switch.

Ignition feed voltage is supplied to the MODE switch and starter relay through the engine fuse. ECM turns the starter relay "ON" by grounding the starter relay driver circuit.

The starter motor is operated 5 to 12 seconds based on coolant temperature.
