SOURCE: Brake fluid leak on driver side rear wheel, anti-lock brakes area

you should be looking for the drivers side wheel (brake) cylinder it is inside the drum with the brakes at the top usually, look at the cylinder on each end there is a small black rubber cap, pull it back a little in one spot and see if brake fluid runs out, if so replace it. Also possible that the brake line is leaking, so check it out too.

SOURCE: 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).

SOURCE: Anti lock brake light won't go off

Check all the wiring to each wheel for a sensor is attached to the back side of each one. Road debries can shear a wire in two and cause the ABS light to stay on and have good brakes at the same time

SOURCE: rear Anti Lock & Brake indicator lights come on

There is a sensor on top of rearend housing. Remove it and clean off the debris (will be fine metallic particles)-replace sensor-reset the computer (disconnect battery power for a few moments-reconnect battery-you're done. If this does not work-you'll have to replace the sensor.

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

Meaning of warning lights


Manufacturers spend billions of dollars a year refining their cars' on-board diagnostics systems. However, all of the sophisticated diagnostics in the world will do little good if you don't know what the warning lights mean.
Purpose
Modern automobiles have dozens of sensors to monitor engine, braking and chassis performance. Any deviation from the car's established limits will trigger a dashboard warning light.


Check Engine Light
Check engine lights can indicate failure of the emissions system, fuel injection system, faulty sensor feedback, overheating or lack of voltage, transmission failure, and engine knock ignition system failure.


Brake Lights
Almost all cars have two separate lights for the braking system: a red "ABS" (anti-lock braking system) light and "Brake Warning" light. The former indicates failure of the electronic anti-lock system, the latter a loss of fluid pressure in the brake system itself.


Dynamic Warnings
Many modern cars have traction or stability control systems that prevent and notify the driver of tire slippage. These lights can come in the form of amber "SLIP," "TC," or "TRACTION" lights (for spinning tires), or "ESC" (electronic stability control) lights for a sliding vehicle.


Safety Lights
Most cars have a diagrammatic warning that indicates a door that isn't all the way closed, a seat-belt warning light, and an "airbag disabled/enabled" light. Any or all of these will be red or amber.

Sounds like a brake light. Check your brake fluid and fill to the correct level if low then see if it goes out.

The Brake light says "BRAKE" is the Brake System Warning Light: "This light monitors various brake functions, including brake fluid level and parking brake application. If the brake light turns on, it may indicate that the parking brake is applied, that the brake fluid level is low, or that there is a problem with the anti-lock brake system (if equipped)."

Another is the Anti-Lock Brake System Light: "This light monitors the Anti-Lock Brake System. The light will turn on when the ignition switch is turned to the ON position and may stay on for as long as four seconds. If the ABS light remains on or turns on while 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 if the BRAKE warning light is not on."

It could also be the Tire Pressure Monitoring light. Check the brake fluid first and see if that fixes it.

I have a warning light on my dash saying there is a problem with the ABS system. Is this a safety problem?


not really. Measn that you most likely have a wheel speed sensor bad. Most often its in the front of the truck and its replaced with the wheel bearing. Although the system is disabled while the light is on the vehicle brakes are not affected

Brake warning lamp on steady only when engine running. Brake fluid level is ok. General brake operation is normal. When park brake set, brake warning lamp is brighter. Is it possible that the rear brake...


No.
It might be in the switch for the parking brake. Try to release it a little more with your hands. It's either in the parking brake system or the regular brake system. Anything ABS has it's own warning light. Have it checked by a tech; it's a safety item, ok?

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
