Diagnosis Procedure

OFF-ROAD LAMP COVER SENSOR CIRCUIT


Description

The off-road lamp cover sensors sense the presence of the off-road lamp covers. If the off-road lamp covers are installed on the vehicle, the BCM will not activate the off-road lamps. The BCM controls the off-road lamps relay based on inputs from the combination switch, the off-road lamps switch and the off-road lamp cover sensors. When the off-road lamps relay is energized, power flows from the off-road lamps relay to the off-road lamps assembly.

Diagnosis Procedure

Regarding Wiring Diagram information, OFF-Road Lamps.
1.CHECK OFF-ROAD LAMPS FUSE
1. Turn the ignition switch OFF.
2. Check that the following fuses are not open.





Is the fuse open?
YES - Repair the harness and replace the fuse.
NO - GO TO 2
2.CHECK OFF-ROAD LAMP COVER SENSOR VOLTAGE





1. Turn the ignition switch OFF.
2. Disconnect the off-road lamp assembly connectors.
3. Turn the ignition switch ON.
4. Check the voltage between the off-road lamp assembly connectors and ground.





Is battery voltage present?
YES - GO TO 3
NO - Repair harness or connector.
3.CHECK OFF-ROAD LAMP COVER SENSOR GROUND CIRCUIT
1. Turn the ignition switch OFF.





2. Check continuity between the off-road lamp assembly harness connectors and ground.





Does continuity exist?
YES - GO TO 4.
NO - Repair the harness.
4.CHECK OFF-ROAD LAMP COVER SENSOR SIGNAL CIRCUIT
1. Disconnect BCM connector M19.





2. Check continuity between the off-road lamp assembly harness connectors (A) and BCM harness connector (B).





3. Check continuity between the off-road lamp assembly harness connector and ground.





Is inspection result normal?
YES - Replace the off-road lamp cover sensor.
NO - Repair the harness.
