Troubleshooting Hints

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check INDIC Fuse.
2. Check that G119 is clean and tight.
3. Check brake fluid. If low, refer to Brakes.
4. If brake fluid is LO and the "BRAKE" Indicator does not light, check the Brake Fluid Level Switch.
5. If "BRAKE" Indicator is lit, check for trouble codes. Refer to Computers and Control Systems. Testing and Inspection
6. If equipped with Daytime Running Lights (DRL), and the "BRAKE" Indicator does not light with the Park Brake set, check CKT 33, CKT 1134 and Park Brake Switch for an open or short to B+. If OK, replace the DRL Module.
7. If the "BRAKE" Indicator does not light at all, check:
- The "BRAKE" Indicator bulb for an open.
- The Instrument Cluster printed circuit for an open.
- CKT 33 for an open.
^ 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 General Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis. System Diagnosis
