Starting System - INGENIUM I6 3.0L Petrol (G2299999): Overview

The Mild Hybrid Electric Vehicle (MHEV) starting system consists of:

• A starter motor that engages with the ring gear on the crankshaft drive plate.
• A BISG  which engages the BISG  drive belt to start the engine.

Operation of the starter motor and the BISG  is controlled by the PCM.  The starter motor is used for engine start when it is initiated by the driver with the ignition switch. Otherwise the PCM  controls the BISG  to start the engine.

The starting system incorporates an auto stop/start system. The PCM  interacts with other vehicle systems to determine when auto stop/start intervention is required. The auto stop/start warning indicator provides a visual indication when the engine is stopped in a stop/start cycle. The auto stop/start system automatically stops and restarts the engine when appropriate conditions are met. This reduces the amount of time the engine is running at idle speed which improves economy and reduces engine emissions.

The auto stop/start system is automatically enabled each time the ignition is switched ON (Power Mode 6). The driver can disable the system using the auto stop/start switch.

The auto stop/start system incorporates a brake vacuum sensor to enable the PCM  to monitor the pressure in the brake booster during stop/start operation.
