BCM - DIMMING LEVEL SWITCH FAILURE —
TEST
2 Turn the ignition on.
With the DRB, select Body Computer then Sensors. Read the Dimming Level Volts.
Set the Panel Dimmer Switch in the Low position then slowly move the switch to the
Hi position, then Funeral Mode position, then to the Dome position.
NOTE: The voltage should increase from approximately 0.6 volts in Low to
5.5 volts in Hi.
NOTE: Funeral mode voltage should be approximately 7.2 volts and Dome
mode should be approximately 9.4 volts.
Does the dimmer level volts display correct voltage for the corresponding position as
described?
Yes → Test Complete.
→ Replace the Headlamp Switch.
No
3 Turn the ignition on.
With the DRB, select Body Computer then Sensors and observe the dimming level
voltage.
Is the voltage above 10.2 volts?
Yes → Go To 4
→ Go To 9
No
4 Turn the ignition off.
Disconnect the Headlamp Switch harness connector.
Disconnect the BCM C2 harness connector.
Measure the resistance of the Headlamp Switch Return circuit between the Head-
lamp Switch connector and the BCM C2 connector.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the Headlamp Switch Return circuit for an open.
No
5 Turn the ignition off.
Disconnect the Headlamp Switch harness connector.
Disconnect the BCM C2 harness connector.
Measure the resistance of the Panel Lamp Dimmer Signal circuit between the
Headlamp Switch connector and the BCM C2 connector.
Is the resistance below 5.0 ohms?
Yes → Go To 6
→ Repair the Panel Lamp Dimmer Signal circuit for an open.
No
6 Turn the ignition off.
Disconnect the Headlamp Switch harness connector.
Disconnect the BCM C2 harness connector.
Turn the ignition on.
Using a 12-volt Test Light connected to ground, probe the Panel Lamp Dimmer
Signal circuit.
Is the test light illuminated?
Yes → Repair the Panel Lamp Dimmer Signal circuit for a short to
→ Go To 7
