TROUBLESHOOTING HINTS

｠

Burned-out fog light bulb

｠

Damaged harness wires and connectors

DIAGNOSIS

Required Special Tools:

｠

MB992006: Extra fine probe

｠

MB991223: Harness set

STEP 1. Check fog light (LH) connector A-41, fog light (RH)
A-51 for loose, corroded or damaged terminals, or terminals
pushed back in the connector.

Q:Is fog light (LH) connector A-41, fog light (RH) A-51 in

good condition?

YES:

Go to Step 2.

NO:

Repair the damaged parts.

STEP 2. Check the fog light bulb.

(1)

Remove the fog light bulb.

(2)

Verify that the fog light bulb is not damaged or burned out.

Q:Is the fog light bulb in good condition?

YES:

Go to Step 3.

LIGHTING

DIAGNOSIS

NO:

Replace the fog light bulb. Verify that the fog

lights illuminate normally.

Step 3. Check the ground circuit to the fog light (LH) or fog
light (RH). Measure the resistance at fog light (LH)
connector A-41 or fog light (RH) connector A-51.

(1)

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

ZC5010410046

Connectors A-41, A-51
(Harness side)

(2)

Check the resistance between the fog light connector and
ground.

｠

Resistance between A-41 fog light (LH) connector terminal
No.1 and ground

｠

Resistance between A-51 front fog light (RH) connector
terminal No.1 and ground

OK: The resistance should be 2 ohm or less.

Q:Is the measured resistance 2 ohms or less?

YES:

Go to Step 5.

NO:

Go to Step 4.

Step 4. Check the wiring harness between fog light (LH)
connector A-41 or fog light (RH) connector A-51 (terminal 1)
and ground.

NOTE:

Also check intermediate connector A-46 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connector A-46 is damaged,
repair or replace the connector as described in GROUP 00E,
Harness Connector Inspection P.00E-2.

｠

Check the ground wires for open circuit.

Q:Is the wiring harness between fog light (LH) connector

A-41 or fog light (RH) connector A-51 (terminal 1) and

ground in good condition?

YES:

The trouble can be an intermittent malfunction

(Refer to GROUP 00 - How to Cope with Intermittent
Malfunction P.00-15).

NO:

Repair the wiring harness.

STEP 5. Check fog light relay connector A-14X for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is fog light relay connector A-14X in good condition?

YES:

Go to Step 6.

NO:

Repair the damaged parts.

STEP 6. Check the wiring harness between fog light (LH)
connector A-41or fog light (RH) connector A-51 (terminal 2)
and fog light relay connector A-14X (terminal 3).

NOTE:

Also check intermediate connector A-46 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connector A-46 is damaged,
repair or replace the connector as described in GROUP 00E,
Harness Connector Inspection P.00E-2.

｠

Check the power supply line for open circuit.

DIAGNOSIS

Q:Is the wiring harness between fog light (LH) connector

A-41 or fog light (RH) connector A-51 (terminal 2) and fog

light relay connector A-14X (terminal 3) in good

condition?

YES:

Go to Step 7.

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 fog lights
illuminate normally.

STEP 7. Retest the system.

Q:Does the right or left fog light does not illuminate in good

condition?

YES:

The trouble can be an intermittent malfunction

(Refer to GROUP 00, How to use Troubleshooting/inspection
Service Points - How to Cope with Intermittent
Malfunction P.00-15).

NO:

Replace the fog light(s).

Inspection Procedure 3: Fog light indicator does not illuminate/go out normally.
