NOTE:
Perform TEST TC-1A, CHECKING SYSTEM FOR TROUBLE CODES before proceeding. After each repair, perform the TEST CH-VER, VERIFICATION PROCEDURE .
- Verify condition of battery. Ensure battery does not show signs of freezing, leakage, loose battery posts, or low electrolyte/water level. Inspect alternator belt tension and condition. Replace belt if necessary.
- Start engine. Using DRB, set engine speed to 2000 RPM for 30 seconds. Return engine speed to idle and read trouble codes. If trouble codes are present, go to DRB TROUBLE CODES table. If no trouble codes are present, turn engine off with ignition on. Using DRB, actuate alternator field.
- Using DRB in voltmeter mode, backprobe field terminal (Dark Green wire) and then Auto Shutdown (ASD) relay output terminal (Dark Green/Orange wire) at rear of alternator. See Figure. Voltage should cycle from zero to battery voltage every 1.4 seconds.
- While observing DRB voltage cycle display, wiggle wiring harness in sections from rear of alternator to powertrain control module and to auto shutdown relay. If there is any interruption in voltage cycle display, repair wiring where interruption occurred. If there is no interruption of voltage cycle display, test is complete.
