Inspection Procedure K-3

INSPECTION PROCEDURE K-3: Front fog Light: One of the front fog lights does not illuminate.

Front Fog Light Circuit (Part 1):




Front Fog Light Circuit (Part 2):






TECHNICAL DESCRIPTION (COMMENT)
If one of the front fog lights does not illuminate, the front fog light relay or the front fog light bulb may be defective. If the front fog light indicator light does not illuminate, the combination meter may be defective.

TROUBLESHOOTING HINTS
- The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector
- The front fog light bulb may be defective

DIAGNOSIS

Required Special Tools:
- MB991223: Harness Set
- MB992006: Extra Fine Probe

STEP 1. Verify that the front fog lights and the front fog light indicator light illuminate.

Q: Do the front fog lights and the front fog light indicator light illuminate normally?

Only the front fog light (LH) does not illuminate : Go to Step 2.

Only the front fog light (RH) does not illuminate : Go to Step 8.

Only the front fog light indicator does not illuminate : Refer to INSPECTION PROCEDURE K-4 "The front fog light indicator does not illuminate normally." Inspection Procedure K-4

Both of the front fog lights do not illuminate : Refer to INSPECTION PROCEDURE K-1 "Front fog lights do not illuminate when the front fog light switch is turned on." Inspection Procedure K-1

STEP 2. Check front fog light (LH) connector A-24 for loose, corroded or damaged terminals, or terminals pushed back in the connector.






Q: Is front fog light (LH) connector A-24 in good condition?

YES : Go to Step 3.

NO : Repair or replace the damaged component(s). Refer to General (Electrical), Harness Connector Inspection. Check that the front fog lights illuminate normally.

STEP 3. Check the front fog light bulb (LH).

1. Remove the front fog light bulb (LH).
2. Verify that the front fog light bulb (LH) is not damaged or burned out.

Q: Is the front fog light bulb (LH) in good condition?

YES : Go to Step 4.

NO : Replace the front fog light bulb (LH). Verify that the front fog lights illuminate normally.

STEP 4. Check the ground circuit to the front fog light (LH). Measure the resistance at front fog light (LH) connector A-24.




1. Disconnect front fog light (LH) connector A-24 and measure the resistance available at the wiring harness side of the connector.




2. Measure the resistance value between terminal 1 and ground.
- The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 6.

NO : Go to Step 5.

STEP 5. Check the wiring harness between front fog light (LH) connector A-24 (terminal 1) and ground.






Q: Is the wiring harness between front fog light (LH) connector A-24 (terminal 1) and ground in good condition?

YES : No action is necessary and testing is complete.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. Verify that the front fog lights illuminate normally.

STEP 6. Check front fog light relay connector A-07X for loose, corroded or damaged terminals, or terminals pushed back in the connector.






Q: Is front fog light relay connector A-07X in good condition?

YES : Go to Step 7.

NO : Repair or replace the damaged component(s). Refer to General (Electrical), Harness Connector Inspection. Check that the front fog lights illuminate normally.

STEP 7. Check the wiring harness between front fog light relay connector A-07X (terminal 4) and front fog light (LH) connector A-24 (terminal 2).






Q: Is the wiring harness between front fog light relay connector A-07X (terminal 4) and front fog light (LH) connector A-24 (terminal 2) in good condition?

YES : No action is necessary and testing is complete.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. Verify that the front fog lights illuminate normally.

STEP 8. Check front fog light (RH) connector A-31 for loose, corroded or damaged terminals, or terminals pushed back in the connector.






Q: Is front fog light (RH) connector A-31 in good condition?

YES : Go to Step 9.

NO : Repair or replace the damaged component(s). Refer to General (Electrical), Harness Connector Inspection. Check that the front fog lights illuminate normally.

STEP 9. Check the front fog light bulb (RH).

1. Remove the front fog light bulb (RH).
2. Verify that the front fog light bulb (RH) is not damaged or burned out.

Q: Is the front fog light bulb (RH) in good condition?

YES : Go to Step 10.

NO : Replace the front fog light bulb (RH). Verify that the front fog lights illuminate normally.

STEP 10. Check the ground circuit to the front fog light (RH). Measure the resistance at front fog light (RH) connector A-31.




1. Disconnect front fog light (RH) connector A-31 and measure the resistance available at the wiring harness side of the connector.




2. Measure the resistance value between terminal 1 and ground.
- The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 12.

NO : Go to Step 11.

STEP 11. Check the wiring harness between front fog light (RH) connector A-31 (terminal 1) and ground.






Q: Is the wiring harness between front fog light (RH) connector A-31 (terminal 1) and ground in good condition?

YES : No action is necessary and testing is complete.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. Verify that the front fog lights illuminate normally.

STEP 12. Check front fog light relay connector A-07X for loose, corroded or damaged terminals, or terminals pushed back in the connector.






Q: Is front fog light relay connector A-07X in good condition?

YES : Go to Step 13.

NO : Repair or replace the damaged component(s). Refer to General (Electrical), Harness Connector Inspection. Check that the front fog lights illuminate normally.

STEP 13. Check the wiring harness between front fog light relay connector A-07X (terminal 4) and front fog light (RH) connector A-31 (terminal 2).






Q: Is the wiring harness between front fog light relay connector A-07X (terminal 4) and front fog light (RH) connector A-31 (terminal 2) in good condition?

YES : No action is necessary and testing is complete.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. Verify that the front fog lights illuminate normally.
