COMMENTS ON TROUBLE SYMPTOM

If the tail lamps, the position lamps or the licence 
plate lamps do not illuminate, the wiring harness con-
nector(s), the bulb or the fuse may be defective or 
burned out.

POSSIBLE CAUSES

• Burned-out bulb

• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Connector check: F-14 <tail lamp LH> or 

F-08 <tail lamp RH> rear combination lamp 

connector, A-31 <position lamp LH> or A-39 

<position lamp RH> headlamp assembly 

connector, F-11 <licence plate lamp LH> or F-10 

<licence plate lamp RH> licence plate lamp 

connector, C-02 <tail lamp indicator> 

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 tail lamps, the 
position lamp, the licence plate lamp or tail lamp 
indicator.
Check the bulb of the lamp which does not illumi-
nate.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the bulb of the lamp which does not 
illuminate.

Step 3. Resistance measurement at the F-14 <tail 
lamp LH> or F-08 <tail lamp RH> rear 
combination lamp connector, the A-31 <position 
lamp LH> or A-39 <position lamp RH> headlamp 
assembly connector, the F-11 <licence plate lamp 
LH> or F-10 <licence plate lamp RH> licence 
plate lamp connector or C-02 <tail lamp 
indicator> 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 A-31 <position lamp LH> 

headlamp assembly connector terminal No.7 
and body earth

• Resistance between A-39 <position lamp 

RH> headlamp assembly connector terminal 
No.7 and body earth

•

Resistance between F-14 <tail lamp LH> rear 

combination lamp connector terminal No.5 
and body earth

• Resistance between F-08 <tail lamp RH> rear 

combination lamp connector terminal No.5 
and body earth
