(RH) connector A-35 (terminal 1) and ETACS-ECU 
connector C-219 (terminal 9) in good condition?
YES : Replace the side turn-signal lamp socket (RH). Verify 

that the turn-signal lamps illuminate normally.

NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. Verify that 
the turn-signal lamps illuminate normally.

STEP 26. Check rear combination lamp (LH) connector 
F-09 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Is rear combination lamp (LH) connector F-09 in good 

condition?
YES : Go to Step 27.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the turn-signal lamps illuminate 

normally.

STEP 27. Check the rear turn-signal lamp bulb (LH).
(1) Remove the rear turn-signal (LH) lamp bulb.
(2) Verify that the rear turn-signal lamp bulb (LH) is not 

damaged or burned out.

Q: Is the rear turn-signal (LH) lamp bulb in good condition?

YES : Go to Step 28.
NO :  Replace the rear turn-signal (LH) lamp bulb. Verify

STEP 28. Check the ground circuit to the rear combination 
lamp (LH). Measure the resistance at rear combination 
lamp (LH) connector F-09.
(1) Disconnect rear combination lamp (LH) connector F-09 and 

measure the resistance available at the wiring harness side 
of the connector.

(2) Measure the resistance value between terminal 2 and 

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 30.
NO :  Go to Step 29.

STEP 29. Check the wiring harness between rear 
combination lamp (LH) connector F-09 (terminal 2) and 
ground.
Q: Is the wiring harness between rear combination lamp 

(LH) connector F-09 (terminal 2) and ground in good 
condition?
YES : Replace the rear combination lamp socket assembly 

(LH). Verify that the turn-signal lamps illuminate 
normally.

NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. Verify that 
the turn-signal lamps illuminate normally.
