to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Check that the taillamp (RH) illuminates 

normally.

STEP 13. Check the stop/taillamp bulb (RH).
(1) Remove the stop/taillamp bulb (RH).
(2) Verify that the stop/taillamp bulb (RH) is not damaged or 

burned out.

YES : Go to Step 14.
NO :  Replace the stop/taillamp bulb (RH). Verify that the 

taillamp (RH) illuminates normally.

STEP 14. Check the ground circuit to the rear combination 
lamp (RH). Measure the resistance at rear combination 
lamp (RH) connector F-03.
(1) Disconnect rear lamp (RH) connector F-03 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 17.
NO :  Go to Step 16.
