Actions Taken When the DTC Sets
The front fog lamps will not operate when the park lamps are ON and the front fog lamp switch is active.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear once 100 consecutive malfunction-free ignition cycles have occurred.

Circuit/System Testing
1. Ignition OFF, disconnect the fog lamp relay.
2. Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal 87 and ground.
瀚慖f the test lamp illuminates, test the control circuit for a short to voltage.
3. Verify that a test lamp illuminates between the B+ circuit terminal 30 and ground.
瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the
B+ circuit fuse is open, test the control circuit terminal 87 for a short to ground. If the circuit tests normal, test or replace the fog lamp
relay.
4. Verify that a test lamp illuminates between the B+ circuit terminal 85 and ground.
瀚慖f the test lamp does not illuminate, test the B+ circuit for an open/high resistance.
5. Disconnect the harness connector at the appropriate fog lamp front.
6. Test for less than 5 ohm between the fog lamp front ground circuit terminal B and ground
瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
7. Connect the harness connector at the fog lamp front.
8. Connect a 15 A fused jumper wire between the B+ circuit terminal 30 and the control circuit terminal 87. Verify the fog lamp front is
activated.
瀚慖f the fog lamp front does not activate and the circuit fuse is good, test the control circuit for an open/high resistance. If the circuit tests
normal, test or replace the fog lamp front.
瀚慖f the fog lamp front does not activate and the circuit fuse is open, test the control circuit for a short to ground. If the circuit tests normal,
test or replace the fog lamp front.
9. Connect a test lamp between the B+ circuit terminal 85 and the control circuit terminal 86.
10. Command the Fog Lamps ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded

Actions Taken When the DTC Sets
* The low beam headlamps are always ON in the AUTO position. The headlamp switch operates in all positions other than AUTO. The AUTO
headlamp defeat is inoperative.
* The low beam headlamps are always ON. The BCM disregards all headlamp switch inputs.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear once 100 consecutive malfunction-free ignition cycles have occurred.

Circuit/System Testing
1. Ignition OFF, disconnect the X2 harness connector at the BCM.
2. Connect a test lamp between B+ and the signal circuit terminal 17.
3. Turn the headlamp switch between the AUTO and AUTO disable positions. The test lamp should turn ON and OFF as the switch is cycled.
瀚慖f the test lamp is always OFF, test the signal circuit for a short to voltage or an open/high resistance. If the circuit test normal, replace the
headlamp and panel dimmer switch.
瀚慖f the test lamp is always ON, test the signal circuit for a short to ground. If the circuit test normal, replace the headlamp and panel
dimmer switch.
4. Connect a test lamp between B+ and the signal circuit terminal 3.
5. Turn the headlamp switch to the ON and OFF positions. The test lamp should turn ON and OFF as the switch is cycled.
瀚慖f the test lamp is always OFF, test the signal circuit for a short to voltage or an open/high resistance. If the circuit test normal, replace the
