High Beam Indicator Inoperative
- Turn ignition off. Remove instrument cluster. See INSTRUMENT CLUSTER
under REMOVAL & INSTALLATION. Disconnect instrument cluster connector C215. See Figure
. Turn ignition on. Turn multifunction switch to high beam position. Measure voltage between ground and instrument cluster connector C215 terminal No. 6 (Gray/White wire). If voltage is more than 10 volts, go to next step. If voltage is less than 10 volts and vehicle is equipped with Daytime Running Lights (DRL), go to step 4). If voltage is less than 10 volts and vehicle is not equipped with DRL, repair open in Gray/White wire.
- Turn ignition off. Measure resistance between ground and instrument cluster connector C215 terminal No. 7 (Black wire). If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms, repair open in Black wire between instrument cluster connector and ground.
- Turn ignition off. Check for continuity across high beam indicator bulb. If continuity exists, replace instrument cluster printed circuit. See PRINTED CIRCUIT
under REMOVAL & INSTALLATION. If continuity does not exist, replace bulb.
- Turn ignition off. Disconnect DRL module. DRL module is located on left side of lower radiator core support. Turn headlight switch on. Ensure multifunction switch is in high beam lights on position. Measure voltage between ground and DRL module terminal No. 8 (Light Green/Black wire). See Fig 1
. If voltage is more than 10 volts, go to next step. If voltage is less than 10 volts, repair open or short in Light Green/Black wire.
- Measure resistance of Gray/White wire between instrument cluster connector C215 terminal No. 6 and DRL module connector terminal No. 1. If resistance is less than 5 ohms, replace DRL module and retest system. If resistance is more than 5 ohms, repair open in Gray/White wire between instrument cluster connector and DRL module.
