Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Anti-lock brake system. TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module. TPMS Tire Pressure Monitor System

If you see alternator light flashing or low battery light when alternator failing not supplying 12 to 14 volts the abs and brake will turn on i have seen that happen before.

Why r my tail lights staying on my 1993 gmc Sierra

Are you sure it is the tail lights and not the brake lights? If the park lights are staying on, the front should be on as well in most cases. If it is the brake lights staying on, suspect a faulty brake light switch located at the brake pedal

Brake lights r stay on when key is on goes out with key off

Do all brake lights stay on including high mount? If all stay on suspect problem with brake switch located at brake pedal. If just lower brake lights stay on ( not including high mount ) expect problem with multifunction switch ( signal switch )

Abs light stays on and brake light on 98 durango

The regular brake warning light is for the parking brake being applied or the brake fluid is low. You would need to get the abs system scanned for trouble codes to proceed.

Brake light stays on just happened 143000 miles

Check your brake switch as it could be faulty hence causing a close circuit which in turn causes the brake light to stay on.It is normally located at the top of the brake pedal.Hope this helps.
