[54B] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Hong Kong spec.> - - SYMPTOM PROCEDURES - FOG LAMP - INSPECTION PROCEDURE M-3: One of the fog lamps does not illuminate. | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE M-3: One of the 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 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 fog lamp bulb Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Connector check: A-24 <RH> or A-19 <LH> front fog lamp connector, or C-05 <front fog lamp indicator lamp> combination meter connector Q: Is the check result normal? YES: Go to Step 2. NO: Repair the connector.
| Step 2. Check the bulbs of the fog lamps or the 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. Measure the resistance at A-24 <RH> or A-19 <LH> front fog lamp connector, or C-05 front fog lamp indicator lamp> combination meter connector. Disconnect the connector, and measure at the wiring harness side. Check the resistance between the front fog lamp connector and body earth. Resistance between A-24 <RH> front fog lamp connector terminal No.2 and body earth Resistance between A-19 <LH> front fog lamp connector terminal No.2 and body earth Resistance between C-05 <front 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 A-24 <RH> or A-19 <LH> front fog lamp connector terminal No.2, or C-05 <front fog lamp indicator lamp> combination meter connector terminal No.12 to body earth. 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: A-05X front fog lamp relay connector Q: Is the check result normal? YES: Go to Step 6. NO: Repair the connector.
| Step 6. Check the wiring harness from A-24 <RH> or A-19 <LH> front fog lamp connector terminal No.1, or C-05 <front fog lamp indicator lamp> combination meter connector terminal No.7 to A-05X front fog lamp relay connector terminal No.4. NOTE: Prior to the wiring harness inspection, check intermediate connector C-116 <front fog lamp indicator 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 front fog lamp and the front 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 front fog lamps do not illuminate.: Replace the front fog lamp(s). The front fog lamp indicator lamp does not illuminate.: Replace the combination meter.
