Diagnostic Test
1. INSPECT THE RIGHT FOG LAMP BULB
NOTE: If both of the fog lamps are inoperative, inspect Fuse 9 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 Right Fog Lamp bulb and inspect for an open filament.
Is the Bulb filament open?
Yes
- Replace the Right Fog Lamp bulb. Fog Lamp - Removal.
- Perform BODY VERIFICATION TEST. Body Verification Test
No
- Go to 2
2. MEASURE FUSED B(+) CIRCUIT RESISTANCE
Disconnect the Right Fog Lamp harness connector.
Disconnect the Illumination Control Module harness connector.
NOTE: Check connectors - Clean/repair as necessary.
Measure the resistance between the Right Fog Lamp harness connector and 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 Right Fog Lamp and the Illumination Control Module.
- Perform BODY VERIFICATION TEST. Body Verification Test
3. MEASURE RIGHT FOG LAMP VOLTAGE
Connect the Illumination Control Module harness connector.
Turn the ignition on.
Turn the fog lamps on.
Measure the voltage between the Right Fog 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 RIGHT FOG LAMP GROUND CIRCUIT RESISTANCE
Turn the ignition off.
Turn the fog lamps off.
Measure the resistance between the Right Fog Lamp harness connector cavity 1 and ground.
Is the resistance below 5.0 ohms?
Yes
- Make sure that the Right Fog Lamp bulb is installed properly and replace the bulb socket if necessary.
- Perform BODY VERIFICATION TEST. Body Verification Test
No
- Repair the Right Fog Lamp ground circuit for an open.
- Perform BODY VERIFICATION TEST. Body Verification Test
