INITIAL CHECKS
Before proceeding with charging system diagnosis, ensure following conditions are met.
- Battery is fully charged and in good condition.
- Battery cables are in good condition with connections clean and secure.
- Generator belt is in good condition and properly tightened.
- Generator and PCM wiring harness connections are clean and tight.
- Engine ground strap is in place.
UNSTEADY OR LOW CHARGING
Check for loose generator belt, charging resistance too high, defective generator, loose generator ground wire, corroded battery terminals or faulty generator.
OVERCHARGING
Check for grounded generator field wiring or faulty generator.
NOISY GENERATOR
Check for worn or frayed drive belt, loose generator mounting, or faulty generator.
Note. For additional trouble shooting information, refer to the TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL TROUBLE SHOOTING section.
PRECAUTIONS
Before proceeding with diagnosis, observe following precautions.
- Ensure battery is fully charged and charging system is functional.
- Probe PCM connector from pin side. DO NOT backprobe PCM connector.
- DO NOT cause short circuits when performing electrical tests. This will set additional DTCs, making diagnosis of original problem more difficult.
- DO NOT use a test light in place of a voltmeter.
- Always begin repair with lowest DTC number (MIL) or first fault displayed (DRB).
- Always perform verification test after repairs are made.
- Always disconnect scan tool after use.
- Always disconnect scan tool before charging battery.
CLEARING DTCS
PCM automatically clears DTCs from PCM memory after 50 ignition on-off cycles. DTC's can also be cleared using scan tool by following scan tool manufacturer's instructions.
