NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS - 3.0L
article in ENGINE PERFORMANCE. Perform TEST VER-1 after each repair.
- Using scan tool in ohmmeter mode, check resistance of Power Distribution Center (PDC) terminal No. 57 (top terminal of second fuse from right on bottom row, Red/White wire). See Figure. If resistance is less than 5 ohms, repair Red/White wire between PDC and low beam headlamp relay for short to ground. See Figure. If resistance is more than 5 ohms, go to next step.
- Check resistance of low beam headlamp relay connector terminal "D" (Violet/White wire). If resistance is less than 5 ohms, repair Violet/White wire between low beam headlamp relay center and low beam headlamp connector. If resistance is more than 5 ohms, replace headlamp system 40-amp fuse.
