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.

You have a broken wiring harness to one of the front wheel sensors. This is a very common problem. You'll have to have the abs codes read to know which side, and then you can either repair or replace that piece. As the front wheels swing back and forth as you steer, the wires leading out of the fender well to the wheel hub fatigue and break inside the insulation, making it almost impossible to see from the outside where the break is. If you have an ohmmeter and are handy with tools, you can check each front harness for contnuity while wiggling it. This is a little tricky, but it will work if you can't find a way to read the codes.

All are tied into the ABS system, traction as well as stabilization, This needs to be looked at by someone who can hook up a diagnostic tester to read the fault codes stored in the ABS system then perform the correct diagnostic procedures to isolate the problem

  • I suggest taking it back to the mechanic that replaced that HUB and ask why it is not fixed right. What I would think he would have done is checked each senor for voltage while the wheel was turning to see which sensor or sensors are failing. After he replace the one HUB (Wheel Sensor Bearings) he more than likely cleared the codes and reset the light. After a while it came back on because the job problem was not completely fixed. Perhaps another HUB needs replaced. It does need to be addressed soon though as I am sure you know. It should also be scanned again with a high end scanner. I would start with the person that "fixed" your vehicle not long ago.

Whenever this warning or any other stays on in the dash it is indicating that the systems control module has detected a fault, it then disables the system 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)

Clearing/resetting ABS and Traction Control system warning lights - 2006 Buick Terraza

As long as your car's brakes work and is safe to drive, take it to any parts store. They have error code readers that can reset these alarms. If they are not able to reset them then you will probably have to take your car to a brake shop for maintenance on your ABS sensors. Traction control is associated with the ABS sensors.

I'm working on an 05 buick terraza with a code c1101.Can that code be set by a bad steering wheel position sensor?I have already replaced the ebcm and bpmv.

DTC C1101 : Base Brake System Pressure Sensor 2 Range . Has nothing to do with steering wheel position sensor or the EBCM or BPMH !
The electronic brake control module (EBCM) uses an input from 2 brake fluid pressure sensors to enhance Antilock Brake System (ABS) braking and vehicle stability if equipped.
Conditions for Setting the DTC
The 2 master cylinder pressure sensors do not correlate.
your best bet mite be to take it to a qualified repair shop .

2005 Buick Terraza: "Service stability system" comes on seemingly at random at various speeds. At low speed a definite bump is felt as the system engages.At highway speeds no difference in car...

when the warning is on your stability and abs systems are disabled, and yes any braking, or suspension issue is a safety issue and needs addressed, unfortunately taking it to a dealership for diagnostics at least if you plan to replace your own parts is the only way to go. I have an 06 terraza, and have has a few issues that had to be fixed by a dealership tech, luck for me I have been a gm dealership tech for 12 years so i fixed it on my own, but anyways their are severel different codes that can set for this system, so a dealership scantool will have to retrieve the code for you due to the fact only a liscenced gm dealer has the available software for this particular system. I know it sucks but thats the way it is..

Transmission Traction "Off" light stays lit with Traction button

The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.

I had a similiar problem. My car would actually pull to the left it was so bad. I took it to the dealer several times and they could not fix it. Turn out they where simply driving the car around the auto mall circle a couple of times. My wife took them on a 30 mile trip when it finally happened with a service tech in the car. The guy freaked out and had my wife take the car rite back and the service center took possession of the car and gave her a free rental even though the car was not under warranty. Turns out it was a faulty computer brake module, when it goes bad it ingages the traction control/stability control system when it is not needed. Not sure if this is your problem but it is something to think about.
