NEVER lift a vehicle with Air Shocks because you will damage the Shocks themselves. Did you work on the Brakes? Air in your System? Break a Wire?

SOURCE: stability system

the service stability light as well as the abs light is all conected to the wheel sensor. To fix it is simple if you kn,w how to do a brake job,it is all conected to the hub assembly. I replaced both front wheel sensors due to that problem. you can by the hub assembly for around 100.00 dollars at auto zone. the wire that connects to the wheel always breaks and these codes come up.

SOURCE: 2001 oldsmobile silhouette traction corntol is off and ABS light

I agree with the post about the tail lights. And the symptom about the brakes on when starting was also helpful. When I took off my rear tail lights and removed the top light bulb (top of the 4 is closest to connector) then repeat starting the car the problem is gone. I have a whole drawer of these bulbs that I removed, not because the filament was burned out, but because the base (similar to circuit card edge connector) had heat damage and melted. I am not sure exactly what the problem is but I think there are multiple conductors in the fixture which are too close or get moisture shorts. Anyway I hypothesize the circuit for daytime running lights is leaking current into the brake light circuit, and it causes that module that controls traction control and ABS to declare a fault. When you start with foot on the brakes the brake lamp is pulled on (I don't know if switches hi or lo) so that module doesn't declare the fault until you release the brakes.

I put in new bulbs and it works fine for now, but I know it may reappear some day then I will repeat, disassembly of the fixtures and inspect bulb bases for heat damage and clean out and replace. That is what did the trick for me.

Thanks Fixya and all contributors

SOURCE: ABS and service light reset after brake change

the ABS light resets itself every time the key is turned off and on, it is self testing and will only turn the light on when there is a problem in the ABS system, worn out brakes don't cause the ABS to come on, if the light is on the system has a fault present and it must be tested with a factory system scanner to determine the source of the fault or at least the area that is causing the problem, that can be one of the four wheeel speed sensors, a defective ABS hydraulic control unit and sop on.

My 2006 Cadillac STS is braking by itself with all these lights on..stabilize stability system brake assist..etc what is going on could someone help


problem usually narrows down to abs system problem or hub failing causing problem with abs --have vehicle scanned for the trouble code it will assist you as where to start in repairing problem most auto stores offer this service for free --in the mean time pull the abs fuse so brakes can revert to a normal non abs system till repairs can be made

Can you help with multiple electrical issues??


This vehicle is equipped with the BOSCH 5.3 antilock braking system.
The vehicle is equipped with the following braking systems:
• Antilock Brake System (ABS)
• Dynamic Rear Proportioning (DRP)
• Traction Control System (ETS) (w/NW7)
• Traction Control System (TCS) (w/NW9)
• Vehicle stability enhancement system (VSES) You need to have vehicle checked for DTC'S diagnostic trouble codes , do you know what they are ? The traction control , ABS an stability control are all a function of the electronic brake control system .It also seams the power steering is controlled by the Antilock brake system.The Magnasteer® is controlled through the ABS module and varies the torque by adjusting the current flow through the actuator.
Your best place to start would be to have ABS module scanned for DTC'S . Codes would point you in right diagnostic direction .
The following components are involved in the operation of the above systems:
• Electronic Brake Control Module (EBCM), The EBCM controls the system functions and detects failures.
The EBCM contains the following components:
- System Relay, The system relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves and pump motor.
- Vent Tube, The vent tube, located in the EBCM, is an opening to the internal cavity of the EBCM. It allows ventilation of the EBCM internals.
• Brake Pressure Modulator Valve (BPMV), The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.

Service Stable Tracking Light came on


Hi there:

The Traction Control & Stability is a part of the anti lock brake system When these lights come on there has been a failure code set in the computer for a circuit failure.

This can be a sensor problem sometimes or a calibration change for the computer.You should have your local GM dealer check these systems for failures. These 2 systems work together through the EBCM (Electronic Brake Control Module).


Hope this helps.

How do you clear stabillity controll light and abs light


Most likely yu cause a problem with the abs system since the stability control uses this system it will also illuminate when there is an ABS issue. If there where not a problem the light would have gone out. Since the light remains on we now something is wrong. Doyle check your work making sure you didn't accidentally unplug, break, or pull the wires out of a sensor. If nothing looks wrong than your next step is to check for ABS codes with a scan tool.

My ABS light is on and off on a 2006 Mercury Mariner. Do I need to do something to get this light to stay off


SECTION 206-09: Vehicle Dynamic Systems 2006 Escape/Mariner/Escape Hybrid/Mariner Hybrid Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 03/29/2005 Anti-Lock Control adobe.gif Printable View (63 KB) The ABS consists of the following components:
  • Hydraulic control unit (HCU)
  • Anti-lock brake control module
  • Front and rear wheel speed sensors
  • Front and rear wheel speed sensor rings
  • Stability control sensor cluster
  • Stability/traction control switch
The ABS prevents wheel lock-up by monitoring the wheel speed sensors and actuating the HCU modulating the brake pressure to prevent wheel lockup. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system utilizes the same components as the ABS to prevent wheel spin and help maintain vehicle control during acceleration. The roll stability control (RSC) system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel position sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers.
--------------------------------------------------------------------------------------------------------------------------------------
The ABS module is self monitoring. The module will carry out a preliminary electrical check of the hydraulic pump motor by turning the pump ON for approximately 1/2 second either when the ignition switch is turned to the RUN position and the brake pedal is not pressed or when the vehicle is in motion and at vehicle speeds above 20 km/h (12 mph). The ABS module will also carry out a wheel speed sensor self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry when the ignition switch is turned to the RUN position, with or without brake pedal application. If a malfunction is detected in the pump or wheel speed sensors, the ABS module will shut down and disable the anti-lock system. Normal power assisted braking, however, remains.

You may need to have the dealer run a scan test to determine the DTC fault codes. Then go from there. Autozone can't read these codes as tehy are chassis codes. They only can read powertrain codes.

Good luck. please rate.

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..
