If the Remote Function Actuator (RFA) detects a valid smart key the driver will be able to start the engine. Engine cranking is requested when the ignition switch is pressed and the driver has depressed the brake pedal. When the ignition switch is operated the Central Junction Box (CJB) assembly transmits a hardwired crank request to the Powertrain Control Module (PCM).

The energized starter relay supplies battery power to the starter solenoid, which energizes and causes the pinion gear to engage with the ring gear.

When the starter motor solenoid is energized it also closes high-current contacts. The starter motor solenoid connects battery power from the starter fuse on the battery positive terminal to the motor to turn the engine.

When the engine reaches self-sustaining operating speed, the PCM then de-energizes the starter relay to disconnect power from the starter motor. The starter motor solenoid disengages the pinion gear from the drive plate ring gear.
