Starting System - Starting System
Description and Operation
The function of the starting system is to crank the engine fast enough to allow the engine to start. Heavy cables, connectors and switches
are used in the system because of the large currents required.
The starting system consists of a pre-engaged type starter motor, battery, remote control switch (ignition switch) and relay. The operation
of the starter relay is controlled by the engine control module (ECM).
To protect the starter motor from damage, the ECM prevents the starter from being engaged when the engine is running. This is done by the
ECM inhibiting the starter relay operation.
Vehicles equipped with automatic transmission have a transmission range sensor attached to the circuit which prevents operation of the
starter motor unless NEUTRAL or PARK are selected.
USA market vehicles equipped with manual transmission have a clutch pedal start inhibit switch which prevents operation of the starter
motor unless the clutch pedal is operated.
The ECM will only operate the starter relay providing the following conditions are met:
The ignition switch has been in the start position for a predetermined time
The security response between the ECM and the instrument cluster (IC) has passed
The engine is not running
The transmission range switch is in the NEUTRAL or PARK position (vehicles fitted with automatic transmission)
The clutch pedal is operated (USA vehicles fitted with manual transmission)
The starter relay remains energized until one of the following occur:
The maximum cranking time is exceeded
The ECM detects an engine running signal
The ignition switch is no longer in the start position
The transmission range switch is no longer in the NEUTRAL or PARK position (vehicles fitted with automatic transmission)
The clutch pedal is released (USA vehicles fitted with manual transmission)
The set engine speed is reached (vehicles with 2.0L engine)
The vehicle is cranked for 30 seconds and the engine has failed to start
With the ignition switch in the start position, providing the ECM start conditions are met, the starter relay is energized and the engagement
lever moves the pinion into mesh with the engine ring gear teeth. The electrical contacts within the solenoid complete the high power circuit
and the starter motor operates to turn the engine.
The sequence of operation is as follows:
Ignition switch in the start position
Starter relay activated by the ECM
Voltage provided to the starter motor solenoid
Starter solenoid engages the drive pinion to the ring gear
Starter solenoid switches the battery current to the starter motor
The starter remains engaged until the ECM start conditions are no longer met
Vehicles with 2.0L, 2.5L or 3.0L engines
