Diagnostic Test

1. INSPECT THE ASH RECEIVER LAMP BULB
NOTE: If any BCM DTCs are set, diagnose them first before continuing.

NOTE: Inspect Fuse 11 located in the Illumination Control Module/IP Fuse Block. If the fuse is open, repair the cause of the open fuse before continuing.

Turn the ignition off.
Remove the Ash Receiver Lamp Bulb and inspect for an open filament.
Is the Bulb filament open?

Yes

- Replace the Ash Receiver Lamp bulb. Center Console - Removal.
- Perform BODY VERIFICATION TEST. Body Verification Test

No

- Go to 2

2. MEASURE FUSED B(+) CIRCUIT RESISTANCE




Disconnect the Ash Receiver Lamp harness connector.
Disconnect the Illumination Control Module harness connector.

NOTE: Check connector - Clean/repair as necessary.

Measure the resistance of the Fused B(+) circuit from the Ash Receiver Lamp harness connector to the Illumination Control Module harness connector.
Is the resistance below 5.0 ohms?

Yes

- Go to 3

No

- Repair the Fused B(+) circuit for an open between the Ash Receiver Lamp and the Illumination Control Module.
- Perform BODY VERIFICATION TEST. Body Verification Test

3. MEASURE ASH RECEIVER LAMP VOLTAGE




Connect the Illumination Control Module harness connector.
Turn the ignition on.
Turn the parking lamps on.
Measure the voltage between the Ash Receiver Lamp harness connector cavity 2 and ground.
Is the voltage above 10 volts?

Yes

- Go to 4

No

- Replace the Illumination Control Module. Removal.
- Perform BODY VERIFICATION TEST. Body Verification Test

4. MEASURE ASH RECEIVER LAMP GROUND CIRCUIT RESISTANCE




Turn the ignition off.
Turn the parking lamps off.
Measure the resistance between the Ash Receiver Lamp harness connector cavity 1 and ground.
Is the resistance below 5.0 ohms?

Yes

- Ensure that the Ash Receiver Lamp bulb is installed properly and replace the bulb socket if necessary.
- Perform BODY VERIFICATION TEST. Body Verification Test

No

- Repair the Ash Receiver Lamp ground circuit for an open.
- Perform BODY VERIFICATION TEST. Body Verification Test
