INSPECTION PROCEDURE N-4: Any of the rear fog lamps does not illuminate. <vehicles for Argentina>
	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. Measure the resistance at the F-12 rear fog lamp connector or C-05 <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 relay 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-212 rear fog lamp relay 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.16 to C-212 rear fog lamp relay connector terminal No.1. NOTE: Prior to the wiring harness inspection, check intermediate connector C-117 <rear fog lamp>, F-09 <rear fog lamp> and junction block connector C-201 <rear fog lamp and rear 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 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.
