B16F9-FRONT LEFT FOG LAMP CONTROL CIRCUIT HIGH

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.





1. 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: B16F9-FRONT LEFT FOG LAMP CONTROL CIRCUIT HIGH?

Yes

- Go To 2

No

- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (Z904) GROUND CIRCUITS
1. Disconnect the Front Left Fog Lamp harness connector.
2. 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

- Go To 4

No

- Go To 3

3. (Z904) GROUND CIRCUIT OPEN
1. Measure the resistance of the appropriate (Z904) Ground circuit(s) at the Front Left Fog Lamp harness connector.

Is the resistance below 10.0 Ohms?

Yes

- Replace the Inoperative bulb.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the appropriate (Z904) Ground circuit(s) for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. CHECK (L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT
1. Turn the ignition on.
2. With a 12-volt test light connected to ground, check the (L89) Front Left 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 5

5. (L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT OPEN
1. Turn the ignition off.
2. Disconnect the TIPM C4 harness connector.
3. Measure the resistance between the (L89) Front Left Fog Lamp Control circuit and the Front Left Fog Lamp harness connector to the TIPM C4 connector.

Is the resistance below 10.0 Ohms?

Yes

- Go To 6

No

- Repair the (L89) Front Left Fog Lamp Control circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

6. (L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE
1. Turn the ignition on.
2. Measure the voltage of the (L89) Front Left Fog Lamp Control circuit.

Is there any voltage present?

Yes

- Repair the (L89) Front Left Fog Lamp Control circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Totally Integrated Power Module (TIPM).
- Perform the BODY VERIFICATION TEST. Body Verification Test.
