NO: Replace the stop/taillight bulb (LH). Verify that the taillights (LH) illuminate normally.

STEP 19. Check the ground circuit to the rear combination light (LH). Test at rear combination light (LH) connector F-14.




1. Disconnect rear combination light (LH) connector F-14 and measure the resistance available at the wiring harness side of the connector.




2. Measure the resistance value between terminal 5 and ground.
- The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES: Go to Step 22.

NO: Go to Step 20.




STEP 20. Check rear combination light (LH) connector F-14 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Is rear combination light (LH) connector F-14 in good condition?

YES: Go to Step 21.

NO: Repair or replace the damaged component(s). Refer to Harness Connector Inspection. Verify that the taillights (LH) illuminate normally.




STEP 21. Check the wiring harness between rear combination light (LH) connector F-14 (terminal 5) and ground.

Q: Is the wiring harness between rear combination light (LH) connector F-14 (terminal 5) and ground in good condition?

YES: Replace the rear combination light socket (LH). Verify that the taillight (LH) illuminates 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 taillights (LH) illuminate normally.







STEP 22. Check rear combination light (LH) connector F-14 and front-ECU connector A-10X for loose, corroded or damaged terminals, or terminals pushed back in the connector.
