Troubleshooting Hints

1. CHECK the condition of the DRL-FOG FUSE 15 and the GAGES FUSE 4. If either Fuse is open, LOCATE and REPAIR source of overload.
2. CHECK that Grounds G112, G113 (with Fog Lamps or with QUAD Headlamps) and G200 are clean and tight.
3. CHECK that the Fog Lamp Relay is securely mounted in the Convenience Center.
4. CHECK the LH and RH Low and High Beam filaments.
5. CHECK the High Beam Indicator filament.
6. CHECK the LH and RH Fog Lamp filaments.
7. CHECK the Daytime Running Lamps (DRL) indicator filament.
8. CHECK that Daytime Running Lamps (DRL) Relay is securely mounted in Convenience Center. CHECK for a broken (or partially broken) wire inside of the insulation which could cause system failure 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 effect the integrity of other system (Refer "Troubleshooting Procedures"). Diagnostic Aids
