Starting System - V8 S/C 5.0L Petrol (G2796641): Overview

WARNING: This page is about a different variant/trim than selected.

The starting system consists of an electric starter motor that engages with the starter ring gear on the crankshaft drive plate. Operation of the starter motor is controlled by the PCM  . The PCM  initiates starting system operation when a valid smart key is in the vehicle and the ignition switch is operated.

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 re-starts 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.
