Starting System: Description and Operation

Starting System

The starting system consists of the following:

- Starter motor
- Starter relay
- Clutch Pedal Position (CPP) switch (manual transmission only)
- Digital Transmission Range (TR) sensor (automatic transmission only).


Starter Motor

The starter motor:

- is a permanent-magnet, gear reduction, 12V DC motor.
- has an integral starter solenoid.


Starter Relay

The starter relay:

- is a mini ISO relay.
- switches power to the starter solenoid to engage the starter motor when it is provided a ground through the PCM.


Clutch Pedal Position (CPP) Switch

The CPP switch (manual transmission only):

- completes the circuit to the starter ISO relay and provides a signal to the PCM when the clutch pedal is depressed.


Digital Transmission Range (TR) Sensor

The digital TR sensor (automatic transmission only):

- completes the circuit to the starter ISO relay and provides a signal to the PCM when the transmission is in PARK or NEUTRAL.


Starter System - Operation

When the ignition switch is turned to the START position the starter relay switches power to the starter solenoid causing the starter motor to engage as long as:

- the clutch pedal is depressed (manual transmission only).
- the digital TR sensor is in PARK or NEUTRAL (automatic transmission only).
- the anti-theft system is disabled (if equipped).
