Troubleshooting Hints

TRY FOLLOWING CHECKS BEFORE DOING SYSTEM CHECK.
1. Check I/P Fuse Block Fuse 1B (see schematic) by visual inspection.
2. If Backup Lamps light in the wrong gear, adjust/replace Park/Neutral Position Switch.
3. If only some Backup Lamps are inoperative, check bulb(s), connection(s) and wiring to suspect lamp(s).
4. If Lamp Monitor (if equipped) does not indicate a Backup Lamp outage, see Lamp Monitor for diagnosis.
