Charging System Warning Never/Always On
- Bulb Check
Turn ignition off. Remove charging system indicator bulb from instrument cluster. Ensure continuity exists between bulb terminals. If continuity exists, go to next step. If continuity does not exist, replace bulb.
- Indicator Circuit Generator Check
Turn ignition off. Disconnect wiring harness connector from generator. Turn ignition on and ground Brown wire at generator connector. If charging system indicator lights up, repair charging system. If charging system indicator does not light up, go to next step.
- Indicator Circuit Check
Turn ignition off. Disconnect instrument cluster C210 (Black) connector and generator connector. Measure resistance between ground and Brown wire at instrument cluster connector. Measure resistance of Brown wire between instrument cluster connector and generator. If resistance is greater than 10,000 ohms between instrument cluster and ground, and less than 5 ohms between instrument cluster and generator, replace instrument cluster printed circuit board. If resistances are not as specified, repair Brown wire.
