STEP 21. Check the wiring harness between front
combination lamp (LH) connector A-20 (terminal 5) and
ground.
Q: Is the wiring harness between front combination lamp

(LH) connector A-20 (terminal 5) and ground in good
condition?
YES : Replace the front combination lamp socket (LH).

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 front park lamp (LH) illuminates normally.

STEP 22. Check the wiring harness between front
combination lamp (LH) connector A-20 (terminal 2) and
front-ECU connector A-11X (terminal 4).
Q: Is the wiring harness between front combination lamp

(LH) connector A-20 (terminal 2) and front-ECU
connector A-11X (terminal 4) in good condition?
YES : No action is necessary and testing is complete.
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 front park lamp (LH) illuminates normally.

STEP 25. Check the ground circuit to the front parking
lamp (RH). Measure the resistance at front combination
lamp (RH) connector A-32.
(1) Disconnect front combination lamp (RH) connector A-32,

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

(2) Measure the resistance value between terminal 5 and

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 27.
NO : Go to Step 26.
