Troubleshooting Hints

1. Check the NSBU Fuse by visual inspection.
2. Check Backup Lamps for damage to filament or corrosion between bulb and socket.
^ Refer to Transaxle Range Switch in Automatic Transaxle.
^ 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
