Starting System - without Intelligent Access (IA): Overview




Starting System - without Intelligent Access (IA)

Overview

The starting system controls the cranking of the engine. The starter motor is enabled by the starter relay when the relay is activated by the PCM (Powertrain Control Module). The PCM (Powertrain Control Module) receives inputs from the ignition switch, TCM (Transmission Control Module) (automatic transmission) or CPP (Clutch Pedal Position) switch (manual transmission) and the BCM (Body Control Module) before activating the starter relay to initiate cranking of the engine.
