- Ignition OFF, disconnect the harness connector at the dimmer switch.
- Test for less than 1 Ξ© of resistance between the low reference circuit and ground.
- If greater than 1 Ξ©, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
- Ignition ON, verify the scan tool I/P dimmer input is greater than 4.5 volts.
- If less than 4.5, test the signal circuit for a short to ground. If the circuit tests normal, replace the BCM.
- Install a 3-amp fused jumper wire between the signal circuit and the low reference circuit. Verify the scan tool dimmer switch is less than 5.
- If greater than 5, test the signal circuit for a short to voltage or an open/high resistance.
- Reconnect the dimmer switch.
- Ignition ON, turn the headlamp switch to the HEAD position.
- Rotate the I/P dimmer switch to the high and then low illuminations settings. The I/P back lighting should brighten and dim with each rotation.
- If the back lighting does not change intensity, test the instrument panel lamp supply voltage circuit for a short to voltage.
- If the circuit tests normal, replace the BCM.
