SOURCE: 2005 Impala abs & traction control problem

The traction control works off of the abs.So when abs has problem traction is disabled. If problem started when brakes changed most likely one of these sensors. Check rear wiring and see if you can see any physical damage.

You still have issues with the speed sensors. The wires that connect to the hubs are known for failure.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

SOURCE: Service Active Handling, ABS and Traction Control Lights on

I have had exactly the same problem on and off for 3 years now - and just solved it last week thanks to another computer site. Remove and disassemble both grounds from the top of both the left and right frame rails adjacent to the front corners of the engine block. Completely clean the green corrosion from the internal parts with fine sandpaper and add dielectric grease then re-assemble. Clean the mounting bolt and frame hole while you're at it. Sounds time consuming and difficult, but it ain't. No more than 45 minutes combined. I am a technical airhead so if I can do it so can you. What clued me in was the problem always occurred around wet or humid weather. Also, the clock would always lose time overnite. That has ceased also. Good luck. Anyone know why my left headlite, when deployed, vibrates and shimmys??? Sully ptsully@roadrunner.com

Abs light came on


What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control. How this system works: Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid. Common reasons for this to happen:
  • ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
  • Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working. What to expect: A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. How important is this service? It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

2002 Buick Rendezvous Service traction system and ABS lights, grinding when turning ans braking


The ABS and Service Traction system may be due to bad sensors or signal reaching the ABS/Traction Control computer. The grinding may be due to uneven or unsmooth rotors, and/or worn out pads or shoes.

I would recommend that the entire braking system be diagnosed at your local dealer or brake service facility.

2001 olds ABS and traction control sensor issue


An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
