Cargo Lamps

1. CHECK condition of CTSY Fuse. If Fuse is open, LOCATE and REPAIR source of overload. REPLACE Fuse.
2. CHECK operation of Dome and Courtesy Lamps. If inoperative, REPAIR before proceeding with Cargo Lamp diagnosis.
- 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
