Troubleshooting Hints

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check I/P Fuse Block PARK LPS/INT LPS Fuse 6C, SIG/BU/LPS BTSI/COR Fuse 1B, IGN (RUN/CRANK) CHIME/CLSTR/LCM Fuse 1D, and LCM/HDLP Circuit Breaker by visual inspection.
2. If one Headlamp does not operate, check bulb, socket and related wiring (see schematic).
3. If Headlamps one side are dim, check ground on that side.
4. Check that grounds G101, G104, G105, G201, and G202 are clean and tight.
5. Before component replacement, check that system connections are clean and tight.
^ 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.
