Part 5 of 5

STEP 41. Check the wiring harness between rear side marker light (LH) connector F-20 (terminal 1) and intermediate connector F-12 (terminal 1).

Q: Is the wiring harness between rear side marker light (LH) connector F-20 (terminal 1) and intermediate connector F-12 (terminal 1) in good condition?

YES: Replace the rear side marker light (LH) socket. Verify that the rear side marker light (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 rear side marker light (LH) illuminates normally.




STEP 42. Check the wiring harness between rear side marker light (LH) connector F-20 (terminal 2) and intermediate connector F-12 (terminal 2).

Q: Is the wiring harness between rear side marker light (LH) connector F-20 (terminal 2) and intermediate connector F-12 (terminal 2) in good condition?

YES: Replace the rear side marker light (LH) socket. Verify that the rear side marker light (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 taillight (LH) illuminates normally.




STEP 43. Check rear side marker light (RH) connector F-19 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Is rear side marker light (RH) connector F-19 in good condition?

YES: Go to Step 44.

NO: Repair or replace the damaged components). Refer to Harness Connector Inspection. Verify that the rear side marker light (RH) illuminate normally.

STEP 44. Check the rear side marker light bulb (RH).

1. Remove the rear side marker light bulb (RH).
2. Verify that the rear side marker light bulb (RH) is not damaged or burned out.

Q: Is the rear side marker light bulb (RH) in good condition?

YES: Go to Step 45.

NO: Replace the rear side marker light bulb (RH). Verify that the rear side marker light (RH) illuminate normally.

STEP 45. Check the ground circuit to the rear side marker light (RH). Measure the resistance at rear side marker light (RH) connector F-19.




1. Disconnect rear side marker light (RH) connector F-19 and measure the resistance available at the wiring harness side of the connector.




2. Measure the resistance value between terminal 1 and ground.
- The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES: Go to Step 47.

NO: Go to Step 46.




STEP 46. Check the wiring harness between rear side marker light (RH) connector F-19 (terminal 1) and intermediate connector F-12 (terminal 1).

Q: Is the wiring harness between rear side marker light (RH) connector F-19 (terminal 1) and intermediate connector F-12 (terminal 1) in good condition?

YES: Replace the rear side marker light (RH) socket. Verify that the rear side marker light (RH) 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 rear side marker light (RH) illuminates normally.




STEP 47. Check the wiring harness between rear side marker light (RH) connector F-19 (terminal 2) and intermediate connector F-12 (terminal 2).

Q: Is the wiring harness between rear side marker light (RH) connector F-19 (terminal 2) and intermediate connector F-12 (terminal 2) in good condition?

YES: Replace the rear side marker light (RH) socket. Verify that the rear side marker light (RH) 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 rear side marker light (RH) illuminates normally.
