Troubleshooting Hints

1. CHECK condition of GAUGES FUSE 4. If Fuse is Open, LOCATE and REPAIR source of overload and REPLACE Fuse.
2. CHECK that Engine Ground G105, and I/P Ground G200 is clean and tight.
3. CHECK the "BRAKE" Indicator Bulb for an open filament.
4. CHECK that the Parking Brake is fully released.
5. Make sure that there is an adequate amount of Brake fluid in the reservoir.
6. If any ABS Diagnostic Codes are Set, Refer to Brakes and Traction Control. Brakes and Traction Control
7. If the Brake Indicator only lights for the Ignition Switch in BULB test or for the Park Brake Warning Switch, then Diode 1 in the Underhood Fuse-Relay Center may have opened.
^ 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 "Troubleshooting Procedures"). Diagnostic Aids
