INSPECTION PROCEDURE M-4: One of the rear fog lamps does not illuminate.
 CAUTION
 Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If any of the rear fog lamps do not illuminate, the wiring harness connector(s), the bulb or the fuse may be defective or burned out.
POSSIBLE CAUSES
  • Burned-out rear fog lamp bulb
  • Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Connector check: F-12 rear fog lamp connector or C-05 <rear fog lamp indicator lamp> combination meter connector
Q: Is the check result normal?
YES:  Go to Step 2.
NO:  Repair the defective connector.
Step 2. Check the bulbs of the rear fog lamps or the rear fog lamp indicator lamp.
Check the bulb(s) of the defective lamp.
Q: Is the check result normal?
YES:  Go to Step 3.
NO:  Replace the bulb(s) of the defective lamp.
Step 3. Resistance measurement at the F-12 rear fog lamp connector or C-05 <rear fog lamp indicator lamp> combination meter connector.
  1. Disconnect the connector, and measure at the wiring harness side.
  1. Check the resistance between the lamp connector and body earth.
    • Resistance between F-12 rear fog lamp connector terminal No.1 and body earth
    • Resistance between C-05 <rear fog lamp indicator lamp> combination meter connector terminal No.12 and body earth
    OK: 2 Ω or less
Q: Is the check result normal?
YES:  Go to Step 5.
NO:  Go to Step 4.
Step 4. Check the wiring harness from F-12 rear fog lamp connector terminal No.1, C-05 <rear fog lamp indicator lamp> combination meter connector terminal No.12 to body earth.
NOTE: Prior to the wiring harness inspection, check intermediate connector F-09 <rear fog lamp>, and repair if necessary.
  • Check the earth wires for open circuit.
Q: Is the check result normal?
YES:  The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
NO:  Repair the wiring harness.
Step 5. Connector check: C-35 rear fog lamp-ECU connector
Q: Is the check result normal?
YES:  Go to Step 6.
NO:  Repair the defective connector.
Step 6. Check the wiring harness from F-12 rear fog lamp connector terminal No.2, C-05 <rear fog lamp indicator lamp> combination meter connector terminal No.6 to C-35 rear fog lamp-ECU connector terminal No.5.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-117 <rear fog lamp> and F-09 <rear fog lamp>, and repair if necessary.
  • Check the output lines for open circuit.
Q: Is the check result normal?
YES:  Go to Step 7.
NO:  Repair the wiring harness.
Step 7. Retest the system.
Check that the rear fog lamp and the rear fog lamp indicator lamp illuminate normally.
Q: Is the check result normal?
The lamps illuminate normally at both high and low beams.:  The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
The rear fog lamps do not illuminate.:  Replace the rear fog lamp(s).
The rear fog lamp indicator lamp does not illuminate.:  Replace the combination meter.
