    If there going off there is no failure, But to be safe you should see if it has a history code stored in its system.

Brake and abs light


Check to see if your emergency brake is partially on. Also the abs light goes on when the sensors on the hubs get corroded from salt. They either need to be cleaned or replaced. Mine are on from corrosion from road salt so rather than pay the hefty fee to fix the issue until I can do it myself I just pulled the fuse for ABS in my panel to shut that system off. Perfectly safe to drive without them and not an inspection requirement. Now your abs is probably going on every time you apply the brakes and that is not a good thing!

Abs & brake warning lights come on. if i push the hand/emergency brake and then release it the warning lights turn off. when i ride the brake as i am coming to a stop and release the brake to drive...


{: ) Check first if your brake fluid is low. Better top it up at maximum level. Look also for possible brake fluid leaks. It can also be a fluid sensor or wheel speed sensors at fault. If the warning lights persist, I suggest a scan tool vehicle check to effectively pinpoint the main cause of the warning light issue.

Ford taurus 1996 3.0 ABS ligth on


Hello, These warning lights are pretty accurate. Autozone, Advance, and Oreillys give free scans although the engine system and brake system can require different scanners.

Check your brake fluid level first. The ABS system requires sensors which require counting the revolutions of each wheel. Sometimes the sensors may break, but they can be blinded by dust and debris.

If you have a broken brake pad, the warning light can come on. Often the Emergency brake pad, inside the rear Rotor, can fall apart and trigger an ABS warning.

You need to inspect both the front and rear brakes or take your car to a brake shop for evaluation. Sometimes you can get a free estimate, and some shops can charge for inspecting the Emergency brakes because of the work needed to reach them.

What does the abbreviation ABS mean on my Dash Board of a 1996 Nissan Frontier King Cab truck?


It stands for Anti-lock braking system, and the reason the ABS warning light is on is due to a problem with the ABS system

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

    Mini cooper Warning lights for abs, low tire,traction comes on


    Ok, check the brake fluid level for a start. This could mean a few things. Your brake pads might be worn down, which would bring a yellow warning light on(triangle), at the same time with the pads being low it will have displaced the fluid, making the level low, this would be a red light on. Now because of this the body control module has detected these faults, will have turned the abs off, hence the abs light.
    If brake fluid is low, this could confirm my theory.
    If its low, top up with dot 5 brake fluid and take to garage to have new pads fitted.

    Dash warning light


    Do you mean the ABS and BRAKE lights? If so, the ABS module is bad which causes both lights to come on. After rebooting, the module gets tested and the ABS light will come on after a few seconds. If it a module problem the BRAKE light will also come on. The brakes will work normally, but will not provide the anti-lock feature.
