[54C] SMART WIRING SYSTEM (SWS) USING SWS MONITOR <Hong Kong spec.> - - SYMPTOM PROCEDURES - FOG LAMP - INSPECTION PROCEDURE M-4: One of the rear fog lamps does not illuminate. | PRINT PAGE / INDEX / PRIOR / NEXT

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. Disconnect the connector, and measure at the wiring harness side. 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.
