Troubleshooting Hints

1. Check the TURN-B/U Fuse by visual inspection.
2. Check Back Up Lamps for damage to filament or corrosion between bulb and socket.
3. If one Back Up Lamp is inoperative, check suspect bulb and wiring.
4. If the Back Up Lamps are always on, check the adjustment of the Transaxle Range Switch. If OK, replace the Transaxle Range Switch.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove good in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems. Refer to Troubleshooting Procedures. Diagnostic Aids
