ABS light or ABS activating by model year
What owners say
Abs & emergency dash lights will turn on/off intermittenly; no pattern as to when/how often. Had gm dealer check it. My ebcm had a short, if lights were on, had no ABS, just hydraulic if lights were off. I have ABS. Cost of new module is $1100.00; plus labor!! Dealer suggested I live with it for cost of repair! I agreed, but worried that gm probably were ignoring lights & thinking they had good ABS!!
My ABS light began to come on while driving. I could hear the ABS pump running but the module was not functioning. I pulled the fuse so it would stop running and I could get home. After taking it into auto service they determined it needs a electronic brake control module and has a kelsey & hayes anti-lock system. The work was quoted at over $700. They said it would be safe to drive but I have limited any driving with the truck since it valid.
Shortly after I purchased my 2000 gmc sonoma [xxx] I had a "low speed activation" of the ABS. Some time later the brake warning light was activated. I took the truck to a gmc dealer and was told I had no problems, but they did replace the brake shoes. Ever since then the low speed activation would happen periodically. Recently, the problem has evolved to every day. And I believe this root problem is behind a lot of other brake problems I've had with this vehicle. *nm updated 07/18/2012 *js information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)
When traveling at highway speeds ABS light comes on, and brake light on dash blinks although brakes are not being applied. Brake light will stop blinking if vehicle is slowed down, but the ABS light will stay on until key is taken from ignition. Dealer has seen vehicle 3-4 times, and can not fix it.
Heavy vibration through out vehicle, wear tires improperly on steering axle, ABS no functioning properly
Consumer was traveling 30mph, and upon making a turn onto a street vehicle shut off without prior warning. He lost steering, and threw vehicle in park. Vehicle stopped abruptly. Consumer's head went through the windshield. Driver's side airbag didn't deploy, and driver side seatbelt didn't hold him at all. Second incident occurred traveling about 65mph on highway, and vehicle shut down again. During both incidents ABS braking light appeared on dashboard. Dealership was aware of problem.
Abs pulled when two of the tires on vehicle were not on the same type of road surface, causing vehicle to crash, during the accident, the airbags experienced no deployment, the service manager agreed that the ABS was not functioning properly however the computer showed that none of the sensors failed.
Maumee ohio accident report #004028. Brake failure. Extremely cold weather, ten degrees fahrenheit. Bumper-to-bumper traffic rolling downhill to a light. Both clutch and brake pedals were depressed with strong, steady foot pressure at 15-20 MPH. Abs pulsing activated. Vehicle gradually slowed to 10-15 MPH. But, other vehicles came to a complete stop in the same distance. So, a rear-end collision occurred at 10-15 MPH. It is reasonable to speculate that the road surface was frozen. But, no ice was observed by either driver or by law enforcement. And all of the other (heavy) traffic stopped without incident. This vehicle also exhibits degradation of braking performance on rough pavement; the ABS kicks in with light brake pedal pressure at 15 MPH even on dry pavement, so long as it is somewhat bumpy.
When applying brakes ABS system activates too quickly, causing a collision to occur. Please give any further details.
Vehicle was involved in frontal collision with a chevy full size pick-up at approximately 20-25 MPH. Both ABS/air bags failed to operate/deploy. Vehicle left a skid mark of 20 feet or more. Dealer/manufacturer were contacted.
My 2000 gmc sonoma pick up ABS brakes activate on a daily base. Under 20 MPH and on dry pavement. When they activate they pull to the left that the right. Did they use the wrong tires?
Service bulletins that may apply
Related recalls
Service brakes, hydraulic: antilock/traction control/electronic limited slip
- What is wrong
- Vehicle description: light duty pickup trucks equipped with 4-wheel disc brakes. Some of these vehicles have an antilock brake system (ABS) motor containing an out-of-specification spring clip. This clip could allow the motor bearing to become misaligned. If misalignment occurs, eventually the ABS would be non-functional.
- Risk
- The base brakes would remain fully functional, but the dynamic rear proportioning (drp) system, which optimizes front to rear brake balance, would become inoperative.
- Remedy
- Dealers will replace the brake pressure module valve assembly.
Recall number 00V055000 · Recall details
Service brakes, hydraulic: antilock/traction control/electronic limited slip
- What is wrong
- Vehicle description: s -trucks equipped with 2 wheel drive. These vehicles may have had the right-hand antilock brake system (ABS) module feed pipe and/or brake crossover pipe tube nuts tightened without seating the pipe-flared-ends enough to withstand normal assembly and vehicle inputs without partially unseating. This does not comply with requirements of fmvss no. 105, "hydraulic service brake normal, emergency, and park braking performance."
- Risk
- If this occurred, the seating seal could be broken during vehicle assembly, or from early road inputs or brake fluid cycling, and a leak could occur increasing the brake stopping distance.
- Remedy
- Dealers will inspect the brake pipe union for signs of brake fluid, and if necessary, install a new brake pipe union.
