Starting System: Description
An electrically operated engine starting system is standard factory-installed equipment on this model. The starting system is designed to provide the vehicle operator with a convenient, efficient and reliable means of cranking and starting the internal combustion engine used to power the vehicle and all of its accessory systems from within the safe and secure confines of the passenger compartment. See the owner's manual in the vehicle glove box for more information and instructions on the recommended use and operation of the factory-installed starting system.
The starting system consists of the following components:
- Battery
- Starter Motor
- Starter Solenoid
- Ignition Switch
- Wire harnesses and connections (including the battery cables).
This article provides complete service information for the starter motor. Complete service information for the other starting system components can be located as follows:

- (Refer to ELECTRICAL/IGNITION CONTROL - DESCRIPTION) .
- (Refer to ELECTRICAL/STARTING/STARTER MOTOR - OPERATION) for complete service information and circuit diagrams for the starting system wiring components. See SYSTEM WIRING DIAGRAMS .
It is important that you keep the interdependency of Battery System, Starting System and Charging system in mind when attempting to diagnose any of these systems.
The battery, starting, and charging systems in the vehicle operate with one another, and must be tested as a complete system. In order for the vehicle to start and charge properly, all of the components that are used in these systems must perform within specifications.
The diagnostic procedures used in each of these systems include the most basic conventional diagnostic methods, to the more sophisticated On-Board Diagnostics (OBD) built into the Powertrain Control Module (PCM). Use of an induction-type milliampere ammeter, volt/ohmmeter, battery charger, carbon pile rheostat (load tester), and 12-volt test lamp may be required.
All OBD-sensed systems are monitored by the PCM. Each monitored circuit is assigned a Diagnostic Trouble Code (DTC). The PCM will store a DTC in electronic memory for any failure it detects. Refer to On-Board Diagnostic Test For Charging System for more information. (Refer to ELECTRICAL/STARTING - DIAGNOSIS AND TESTING) .
