Circuit Operation

Manual Transmission
Battery voltage is applied at all times from the positive battery terminal to the starter switch and the normally open starter solenoid contacts. When the starter switch is turned to START and the clutch start switch is closed, battery voltage is applied to the starter relay. The starter relay energizes and applies battery voltage to the starter solenoid coils.The starter solenoid coils energize, the starter solenoid contact closes, and battery voltage is applied to the starter motor. The starter motor engages to start the engine. If the vehicle is equipped with an anti-theft system, the anti-theft and keyless entry control unit grounds the starter relay.

Automatic Transmission
Battery voltage is applied at all times from the positive battery terminal to the starter switch and the normally open starter solenoid contacts. When the starter switch is turned to START and the automatic transmission mode switch is in PARK or NEUTRAL, battery voltage is applied to the starter relay. The starter relay energizes and applies battery voltage to the starter solenoid coils. The starter solenoid coils energize, the starter solenoid contact closes, and battery voltage is applied to the starter motor. The starter motor engages to start the engine. If the vehicle is equipped with an anti-theft system, the anti-theft and keyless entry control unit grounds the starter relay.
