Starting System - INGENIUM I4 2.0L Petrol/INGENIUM I4 2.0L Petrol - PHEV (G2744263): Operation: Notes

When the Remote Function Actuator (RFA) detects a valid smart key inside the vehicle, the driver can start the engine.

For additional information, refer to: DESCRIPTION AND OPERATION .

The BCM  /GWM  receives the crank request signal when:

• The ignition switch is operated with PARK (P) or NEUTRAL (N) selected on the TCS. 
• The brake pedal is fully pressed.

Then the crank request signal is transmitted to the PCM.  When the PCM  receives the crank request signal, the PCM  energizes the starter relay. The starter relay closed contacts causes a voltage to the motor solenoid, which energizes and transmits current into the motor brushes and armature. The armature rotational force is transferred to the drive plate ring gear through the pinion gear. This rotates the drive plate and starts 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 purpose is to disengage the pinion gear from the drive plate ring gear.
