Firstly make sure u didnt break a wire while changing the pad, there are sensors on the brakes, make sure they are plugged in. Else the ABS and hydraulic pump motor electrical relays and 30 amp fuses will be replaced. In addition, the hydraulic pump motor assembly and pressure/warning switch will be inspected and, if required, replaced.

Thanks

Hi
this would indicate the alternator is bad, I would suggest to replace it,OR I would suggest to have the charging system inspected if not charging the ignition relay will not turn off the lights . If that is ok I would inspect the ignition relay and all the fuse links. check all the fuses and the fuse links in the engine compartment, I have also seen the ignition switch cause problems like this, bad connection inside the switch for the run signal.

There is a sensor on each of the front (not sure about the rear) brake calipers that indicate via the dash light when brake pads are worn down and need replacing. The wire is probably broken on one or both of the front wheel calipers. If there is enough slack in the wire you can just splice it back together with splice connectors and seal with heat shrink insulation. My '02 Passat has had it happen twice, first on the drivers side, repaired wire and light went out, then the other side broke, repaired the same way and haven't had any problems since.

My traction control light and anti lock light popped on today and now the brake light popped on. i read the manual and it says to switch the traction control button back to on but i can't find it


I think your traction control button is on the center console behind the Shifter.
But, I don't think that is the problem. That switch will cause the traction control and light to turn on and off. It should not affect the brake light and anti-lock light.

I would first check your brake fluid level. Top it off with the correct fluid. The fluid is a DOT number; like DOT3 or DOT5. Use the correct DOT fluid.
If the fluid is very low, you may need your brake fluid system bled to remove any air. And you may want to check the brake pads. Low fluid may mean you need new pads.

If that doesn't work, go to an auto parts store that will scan your car for ODB2 error codes. AutoZone will do it for free. I suspect you may have a bad wheel bearing. That will cause the ABS and Trac lights to go on. I've replaced GM bearing/sensors on several of my cars. The last one was my 2005 Bonneville. The bearing and sensor are combined in one unit.

Good question, on the antilock system is a bleader too and bleade it the same way you bleade the caliper. After all is done adjust the rear brakes, they should have a drag to them.

In my 03 deville my traction control light is on an my 3rd brake light on the trunk not working


the rear brake light probably needs to have a new bulb. The traction control light on means traction system is off. There is a button I think on the dash or cosole that says TCS...try pushing the button and maybe that will turn light off. At hard throttle TSC keeps wheel from spinning
with the help of wheel speed sensors from the anti-lock brake system.when TSC is off car will drive like a hot rod. the TSC takes away power from engine by reducing power.anti -lock system lets the TSC know that one wheel is spinning faster than the rest.If that helps let me know

Traction control and anti-locks(ABS) lights come on there is sensors that are pluged in behind the rotors check and see if they are disconected or loose sometimes when you change your brake pads they might come loose and not making contact.

Abs light came on and a tc with line through it came on


when you have antilock "problem " on this vehicle you automatically get t\c light, I fixed this problem for a friend when the tire rubbed through one of his abs sensor cables .. just re-connected it don't spend $500 at a "RELIABLE" shop if you can fix this yourself....they will never tell you how easy it might be to repair!!

Brake light nad rear anti lock light wont go off


Check the fluid level, top it off if needed, look for a fill to line on the side of the reservoir. Check rear brake shoes/pads, are they too worn? Replace with new ones. Bleed all 4 wheels, starting with the farthest one, then go to next farthest, and so on. Look for leaks inside the rear wheels. Adjust rear brakes (if shoes not pads).

you probably push air into the ABS unit when getting your lines replace but the Traction Control light might be on because the system might use the wheel speed sensor on the ABS unit to enable the Traction Control.......

Problem with my cruise control and ABS light on 03 Explorer


Anti-Lock Control —Vehicles Built After 03/2002 The 3-channel anti-lock brake system consists of the following components:
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • Anti-lock brake control module (ECU)
  • rear wheel speed sensor
  • rear wheel speed sensor rings
  • yellow anti-lock brake warning indicator
The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components:
  • active brake booster with integral solenoid
  • brake booster release switch
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • stability assist module (ECU)
  • stability assist event indicator
  • lateral accelerometer
  • longitudinal accelerometer (4x4)
  • rear wheel speed sensors
  • rear wheel speed sensor rings
  • steering wheel position sensor
  • yaw rate sensor
  • yellow anti-lock brake warning indicator
  • brake pressure transducer
  • traction control switch
---------------------------------------------------------------------
I suspect the abs issue is causing the speed control not to work if it happened at the same time the cruise control stopped working. When the yellow ABS light comes on, it means the ABS is dactivated. You may have a faulty accelerometer which senses acceleration and yaw (side to side lean). I have not seen a bad one but you said it is sensitive to acceleration.
I would unplug it and see what happens. The connector should have a small tab to depress so you can pull the connector out.
Here is where it is:

Accelerometer Removal and Installation
  1. NOTE: The accelerometer is located under the center, rear passenger seat carpet. (I think you have to remove seat for access).
    Cut the carpeting along the perforations.
  1. Disconnect the electrical connector.
  1. Remove the nuts and remove the accelerometer.

Have dealer hook up tester and pull fault codes if you can't find an easy solution.
Some background info
  • A malfunction in the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.
  • Malfunctions are indicated by the yellow ABS warning indicator in the instrument cluster.
  • The anti-lock brake system is self-monitoring. When the ignition switch is turned to the RUN position, the anti-lock brake control module will carry out a preliminary self-check on the anti-lock electrical system indicated by a three-second illumination of the yellow ABS warning indicator in the instrument cluster.
  • During vehicle operation, including normal and anti-lock braking, the anti-lock brake control module monitors all electrical anti-lock functions and some hydraulic operations.
  • Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20 km/h (12mph), the anti-lock brake control module turns on the pump motor for approximately one-half second. At this time, a mechanical noise may be heard. This is a normal function of the self-check by the anti-lock brake control module.
  • Pedal pulsation coupled with noise while braking on loose gravel, bumps, wet or snowy roads is normal and indicates correct functioning of the anti-lock brake system.
  • Warning Lamp Indicator
    The anti-lock brake system (ABS) uses the yellow ABS warning indicator to alert the driver of a malfunctions in the ABS.
    The yellow ABS warning indicator will come on to warn the driver that the ABS has been turned off due to a symptom that exists in the ABS. Normal power assist braking remains but wheels can lock during a panic stop while the yellow ABS warning indicator is illuminated.

    -----------------------------------------
    Please report back, I am curious if that is what it is. Good luck

    My 1998 Buick LeSabre has two indicator lights that are on


    it is a warning that the computer has detected an error in the anti-lock braking system. it could be caused a number of different reasons, you could be low on brake fluid, or you could need new front or rear brake pads or need adjusted, there could be a loss of pressure in the system and the lines may need bled
