Step 3. Resistance measurement at the F-14 <LH
drive vehicles>, F-08 <RH drive vehicles> rear
fog lamp connector or C-02 <fog lamp indicator
lamp> combination meter connector

(1) Disconnect the connector, and measure at the

wiring harness side.

(2) Check the resistance between the lamp

connector and body earth.

•

Resistance between F-14 <LH drive vehicles>,

F-08 <RH drive vehicles> rear fog lamp relay
connector terminal No.5 and body earth

•

Resistance between C-02 <rear fog lamp indica-

tor lamp> combination meter connector termi-
nal No.48 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-14 <LH
drive vehicles>, F-08 <RH drive vehicles> rear
fog lamp connector terminal No.5, C-02 <rear fog
lamp indicator lamp> combination meter
connector terminal No.48 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

P.00-5

).

NO :

Repair the wiring harness.

Step 5. Connector check: C-219 rear fog lamp
relay connector, C-01 <rear fog lamp indicator
lamp> combination meter connector

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Repair the defective connector.
