Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION

Turn the ignition on.
With the scan tool, clear all DTC's.
Turn the Front Fog Lamps on.
With the scan tool, read DTC's.

Does the scan tool display active: B16FD—FRONT RIGHT FOG LAMP CONTROL CIRCUIT HIGH?

Yes


No

2. CHECK (Z904) GROUND CIRCUITS

Disconnect the Front Right Fog Lamp assembly harness connector.
With a 12–volt test light connected to 12–volts, probe each (Z904) Ground circuit.

Does the test light illuminate brightly on each ground circuit?

Yes


No

3. (Z904) GROUND CIRCUIT OPEN

Measure the resistance of the appropriate (Z904) Ground circuit(s) at the Front Right Fog Lamp harness connector.

Is the resistance below 10.0 ohms?

Yes


No

4. CHECK (L90) FRONT RIGHT FOG LAMP CONTROL CIRCUIT

Turn the ignition on.
With a 12–volt test light connected to ground, check the (L90) Front Right Fog Lamp Control circuit.

Does the test light illuminate brightly with the fog lamp switch turned on, and shut off with the fog lamps turned off?

Yes


No

5. (L90) FRONT RIGHT FOG LAMP CONTROL CIRCUIT OPEN

Turn the ignition off.
Disconnect the TIPM C4 harness connector.
Measure the resistance of the (L90) Front Right Fog Lamp Control circuit between the Front Right Fog Lamp assembly harness connector and the TIPM C4 connector.

Is the resistance below 10.0 ohms?

Yes


No

6. (L90) FRONT RIGHT FOG LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE

Turn the ignition on.
Measure the voltage of the (L90) Front Right Fog Lamp Control circuit.

Is there any voltage present?

Yes


No
