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
