Could be as simple as low fluid level in the master cylinder. Check that first and then if it is not low or filling it and making a few starts and stops does not kill the light then stop by your local parts store and they will read your codes for free and tell you what the problem is. Free is good, bad brakes is bad, but hopefully it is just the fluid level.

My 2005 Chrysler Sebring started and turned off three times now, it just has a blinking red light?


Anti-Lock Warning Light (ABS) - If Equipped This light monitors the Anti-Lock Brake System (ABS) described elsewhere in this manual. This light will come on when the ignition key is turned to the ON position and may stay on for as long as four seconds. If the ABS light remains on or comes on during driving, it indicates that the Anti-Lock portion of the brake system is not functioning and that service is required, however, the conventional brake system will continue to operate normally provided that the BRAKE warning light is not on. If the ABS light is on, the brake system should be serviced as soon as possible to restore the benefit of Anti-Lock Brakes. 24 7 Locksmith Orchard Park NY 716 710 7400 Locksmith Orchard Park NY

What does it mean when my anti-lock brake light comes on and the low traction light comes on and shuts off?


You need to have the ABS system scanned. You probably have a bad wheel speed sensor. most likely located in one of the hub bearings meaning; you may have to replace a hub wheel bearing assy with the faulty sensor. Traction control uses the same speed sensors as ABS. when the warning lights are on the system is not working.

Abs light has come on saab93


THE ABS WARNING LIGHT HAS COME UP

It means there is an issue with the anti lock braking system (ABS). If the warning light has come up it is likely that the ABS is no longer functioning. It is still safe to drive the car and it will brake as normal but the anti lock safety feature will not operate.

You need to have it checked out for faults. The most likely cause is a failed ABS wheel speed sensor which needs to be replaced. There could alternatively be a problem with the ABS pump which is causing the warning.

There is one item you can check yourself. There is a dedicated fuse for the ABS pump/motor. Check the owner's manual and locate the fuse for the ABS motor and check that the fuse has not blown. If it has blown replace it with a fuse of the correct amperage and road test the car. (So if it is a 40 amp fuse for example, make sure a 40 amp fuse is used to replace it.)

2004 Jeep Grand Cherokee The ABS light comes on and stays on. What does this mean?


You may have a faulty sensor, most cases a wheel speed sensor, the light is on warning you that you do not have abs basically your car will stop like an old 70's model car before abs. abs atands for anti lock brakes, it keeps your brakes from locking up under extreme braking.

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
