For a complete wiring diagram, refer to the Wiring Information.

When Monitored:
Continuously.
Set Condition:
When the Totally Integrated Power Module (TIPM) detects a high condition.

Possible Causes
(L90) RIGHT FRONT FOG LAMP CONTROL CIRCUIT OPEN
(L90) RIGHT FRONT FOG LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE
(Z905) GROUND CIRCUIT OPEN
RIGHT FRONT FOG LAMP BULB
TOTALLY INTEGRATED POWER MODULE (TIPM)

1. TEST FOR INTERMITTENT CONDITION

1.	Turn the ignition on.

2.	With the scan tool, clear all DTCs.

3.	Turn the Front Fog Lamps on.

4.	With the scan tool, read DTCs.

Does the scan tool display active DTC B16FD-FRONT RIGHT FOG LAMP CONTROL CIRCUIT HIGH?

Yes

Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

2. CHECK THE (Z905) GROUND CIRCUIT

1.	Disconnect the Right Front Fog Lamp assembly harness connector.

2.	With a 12-volt test light connected to 12-volts, check the (Z905) Ground circuit.

Does the test light illuminate brightly?

Yes

3. (Z905) GROUND CIRCUIT OPEN

1.	Turn the ignition off.

2.	Measure the resistance between ground and the (Z905) Ground circuit in the Right Front Fog Lamp harness connector.

Is the resistance below 5.0 Ohms?

Yes

Replace the inoperative bulb in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

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

1.	Turn the ignition on.

2.	With a 12-volt test light connected to ground, check the (L90) Right Front 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

Replace the inoperative bulb in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

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

1.	Turn the ignition off.

2.	Disconnect the TIPM C4 harness connector.

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

Is the resistance below 5.0 Ohms?

Yes

Repair the open in the (L90) Right Front Fog Lamp Control circuit.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

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

1.	Turn the ignition on.

2.	Measure the voltage of the (L90) Right Front Fog Lamp Control circuit.

Is there any voltage present?

Yes

Repair the short to voltage in the (L90) Right Front Fog Lamp Control circuit.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

Replace the TIPM in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
