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

SOURCE: abs light/traction control light

You can check out what the trouble code is by pushing and holding the information button and the up arrow (right side of instrument cluster above the radio) until all the instrument clusters light. Press the information button (last) to enter test mode. I've had an error C1234, meaning Left rear wheel sensor fault. I found the problem to be a corroded connector under the chasis just under the rear left door about 2 feet in. I had to by-pass (replace 1 wire due to corrosion at the connector.

SOURCE: gmc yukon has the abs & parking brake light

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem

SOURCE: my 2002 impala's service traction control light

Traction control only works when one wheel is spinning faster than the other it trys to even them out so it wont spin...sometimes if one of the wheels come off the ground in an uneven area or if you take a turn too fast and one wheel turns when the other one dont it is designed to operate.
I would remove all wheels and check the braking system...Is it 4 wheel disc or rear drum ?
If it has rear drums you could have a wheel cylinder leak that will sometimes lock the wheel because of fluid contamination....This would cause both lights to come on...If you find no problems
sometimes the abs sensor builds up fragments on the magnet and makes the light come on...
or if the abs sensor is not close enough to the exciter ring it will make the light come on because it will be out of adjustment.....all you do is press the sensor inward until it barely touches the ring and it will adjust itself....You can sometimes clean the magnet if it is contaminated and make the light go off ( only after you reach 6 to 15 mph. it will go off ).If it dont go off you have to buy a sensor.
Also make sure all tires have same amount and plenty of air to keep vehicle in balance/level.

Stability system disabled light on no power


The stability system is software programmed into the ABS - antilock brake control module also the PCM - engine computer . service engine light DTC'S - diagnostic trouble codes stored . Your best bet , take it to a qualified repair shop or the dealer . You don't have the diagnostic equipment or knowledge to tackle this type of problem .

I HAVE A 2004 YUKON AND MY ABS BRAKE LIGHTS KEEP COMING ON. WHAT DO I DO?


Need to run codes. Can use reader at most auto parts stores. Very likely you have bad sensor at the wheel or something has obstructed the end. Code should tell you which wheel.

STABILITY SERVICE MESSAGE


This is the same as a check engine light or an ABS light. All three systems have their own computer and the ability to store error codes. Once in a while all you have to do is hit a bump and a code is stored. I'v been driving my 2004 Denali with this situation for over two years. If you don't feel ANY changes in the steering, braking, or the general conditions of driving than you've got nothing to worry about. If you DO feel a change in any of the above, then have the vehicle serviced asap. Thanks, Dana
