Troubleshooting Hints

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check ABS or ABS/TCS system for proper operation. Refer to Antilock Brake System (ABS). Antilock Brakes / Traction Control Systems
2. Check that system connections are clean and tight before component replacement.
^ 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 System Diagnosis.
