STEP 19. Check the wiring harness between headlight (RH) connector A-35 (terminal 3) and front-ECU connector A-13X (terminal 10).
Q: Is the wiring harness between headlight (RH) connector A-35 (terminal 3) and front-ECU connector A-13X (terminal 10) 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 headlights illuminate normally.
