Try taking it to Autozone or O'reillys and ask if they can scan the ABS computer. It is a separate plug and different than the motor computer.
You probably have a loose piece of brake material in the rear brakes. The warnings have really worked although I have looked at some bad brakes and do not know how the car can figure it out. The traction control is lighting up because both rear wheels are not turning freely with the brake problem.

Most likely you will need rear brake work soon.

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

2003 lincoln ls traction control always on


Have the ABS Braking System tested

You most likely have a Bad Wheel Speed Sensor

The Control Switch on console does absolutely nothing,I know
I have a 2004 LS

You can not disconnect a thing
I have the factory wiring diagrams &
the answer is no

You have dash lights on-- why have you not checked for
codes & resolved the problem,same procedure when
ever any dash light stays on after motor is running

An dash light on you have an OBD2 system failure

VW PASSAT 03 V6. EPC AND TRACTION LIGHT COME ON INTERMITTANTLY.


First, to read VW codes you will want to get yourself a $50 VAG tool. It will read all your systems, not just the ECU.
Electronic Power Control can go out for several reasons. Check your brake lights with the car running. Check you radiator fluid level. If the car is running bad, you could have bad spark plugs/ wires or ignition coil.
The traction control is tied into the ABS system and often causes problems here as well. Each wheel has a speed sensor and magnet wheel in the hub. You can check these for damage by removing the tires for access. The sensors come out by hand, and inside the hole they come out of is the place to check the magnets with a flash light. Apply a small amount of wheel bearing grease to the sensor.
The control unit goes out in these systems at an alarming rate. They can be easily removed, and repaired for under $200 at modulemaster.com
Since it is intermit, I suspect most likely a loose sensor, or electrical connector.
If your brakes feel squishy at all, bleed the brake lines of air and contaminants.
Good Luck!

Three intermittent warning lights


I would think a sensor is going bad , but ,without testing that is just a guess , just like the dealer tech , assuming it's a module or a fuse ! With the light's on checking for DTC'S - diagnostic trouble codes would be a real good first step . The dealer tech should have hooked up the Tech 2 scan tool an checked codes an look at sensor data parameters ....

ABS light and Traction control light stay on. Vehicle brakes ok, but pedal feels "grindy" intermittently when braking


That "grindy" feeling is when the ABS kicks in. It's only suppose to activate when you slam on the brakes and the wheels would normally lock. Instead, ABS will very quickly pump the brakes on and off, to prevent the wheels from locking (making a giant skid mark) and stopping the car more effectively. Generally this only happens if you slam on the brakes or loose traction due to rain or snow while braking. If this is happening often and the brake light is on, on the dash, then you need to get this checked out by a qualified mechanic ASAP.

2001 Mercury Grand Marquis brake and ABS dash lights on and off


The red brake light is the key here. That usually indicateds a hydraulic problem. Check you fluid level in master cylinder and see if it is low. Also the level indicator sensor there in the master cylinder maybe sticking or corrioded. If ABS sees the red brake light it will shut off and turn on the ABS light,also traction control would be disabled as well.

TRACTION CONTROL.


that is what it is desgined to do - reduce acceleration and apply the brakes intermittently when the wheels spin. You have a switch you cn push to disable it. You need to disable each time you start car. See owner manual.

06-10: Traction Control 1996 Contour, Mystique Workshop Manual
DESCRIPTION AND OPERATION Traction Control System The optional traction control system is designed to control wheel spin when accelerating on slippery or loose surfaces. Traction control system is available only with anti-lock brakes. The traction control system includes the following components:
  • Hydraulic control unit.
  • Throttle control actuator (9N825).
  • Traction control switch.
  • Traction control warning indicator.
  • Front brake anti-lock sensor (2C204).
  • Rear brake anti-lock sensor (2C190).
The traction control system operates as follows:
  • System functions by transferring torque from the spinning wheel to the wheel with the most traction.
  • This is achieved by applying the brake at the spinning wheel through the hydraulic control unit or reducing the throttle opening.
  • Traction control braking and throttle control occur at vehicle speeds up to 50 km/h (30 mph).
  • At vehicle speeds above 50 km/h (30 mph), only throttle limiting control is used.
  • If speed control is operating when traction control system engages the traction control system will disengage speed control through the use of a speed control relay. This action is the same as applying the brake pedal with speed control engaged.

Traction Control Switch The traction control switch is located on the instrument panel, left of the steering column.
