Step 3. Resistance measurement at the E-12 rear 
combination lamp (tail: LH) connector or E-03 
rear combination lamp (tail: RH) connector, A-12 
front combination lamp (position: LH) connector 
or A-25 front combination lamp (position: RH) 
connector or E-07 licence plate lamp (LH) 
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-12 front combination lamp 

(position: LH) connector terminal No.6 and 
body earth

• Resistance between A-25 front combination 

lamp (position: RH) connector terminal No.6 
and body earth

•

Resistance between E-12 rear combination lamp 

(tail: LH) connector terminal No.5 and body 
earth

• Resistance between E-03 rear combination 

lamp (tail: RH) connector terminal No.5 and 
body earth

•

Resistance between E-07 licence plate lamp con-

nector terminal No.2 and body earth

OK: Continuity exists (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 E-12 rear 
combination lamp (tail: LH) connector terminal 
No.5 or E-03 rear combination lamp (tail: RH) 
connector terminal No.5, A-12 front combination 
lamp (position: LH) connector terminal No.6 or 
A-25 front combination lamp (position: RH) 
connector terminal No.6 or E-07 licence plate 
lamp (LH) connector terminal No.2 to body earth.

• Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Repair the wiring harness.

Step 5. Connector check: B-134 ETACS-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the defective connector.

Step 6. Check the wiring harness from E-12 rear 
combination lamp (tail: LH) connector terminal 
No.3 or E-03 rear combination lamp (tail: RH) 
connector terminal No.3, A-12 front combination

Prior to the wiring harness inspection, check junction 
block connectors B-128 <tail lamp (LH) or licence 
plate lamp>, B-131 <tail lamp (RH)>, B-112 <position 
lamp (LH)>, B-110 <position lamp (RH)>, joint con-
nector B-23 and B-24, 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/stop lamps, the position lamps 
and the licence plate lamps illuminate normally.

Q: Is the check result normal?

The lamps illuminate normally at both high and low 
beams. : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction 

P.00-13

).

When the tail lamps do not illuminate : 

Replace 

the tail lamp socket.

When the position lamps do not illuminate : 

Replace the position lamp socket.

When the licence plate lamps do not illuminate : 

Replace the licence plate lamp socket.
