vehicles>, F-08 <RH drive vehicles> rear fog lamp 
connector or C-02 <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.

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.
