Diagnosing the Problem
Diagnosing the specific cause requires a systematic approach. Start by checking your brake fluid level. If it’s low, top it off and monitor it for further drops, which would suggest a leak. If the fluid level is adequate, inspect the brake light switch for proper operation. A multimeter can be used to test the switch’s continuity. Next, check the ABS sensors for damage or debris buildup. A scan tool can be invaluable in retrieving diagnostic trouble codes (DTCs) that can pinpoint the source of the problem.
