NOTE: 

Prior to the wiring harness inspection, check interme-
diate connector C-129 <tail lamp, licence plate lamp 
or tail lamp indicator>, C-127 <tail lamp LH or licence 
plate lamp> or F-12 <licence plate lamp>, joint con-
nector C-05 <tail lamp RH, or tail lamp indicator>, 
junction block connector C-210 <tail lamp RH, or tail 
lamp indicator>, C-214 <tail lamp indicator> or C-217 
<tail lamp RH> and repair if necessary.

• Check the output lines for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Repair the wiring harness.

Step 7. Retest the system.
Check that the tail lamps, the position lamps and the 
licence plate lamps illuminate normally.

Q: Is the check result normal?

The all lamps illuminate normally : 

The trouble can 

be an intermittent malfunction (Refer to 
GROUP 00 

− How to Cope with Intermittent 

Malfunction 

P.00-5

).

When the tail lamps do not illuminate : 

Replace 

the rear combination lamp socket assembly.

When the position lamps do not illuminate : 

Replace the position lamp socket.
