Meaning of ABS light


On vehicles equipped with antilock brakes (ABS), a second warning light is provided to warn if a problem occurs within the ABS system. The ABS lamp comes on when the ignition is turned on for a bulb check, then goes out after the engine starts. If the ABS warning light remains on or comes on while driving, it indicates a fault has occurred in the ABS system.

What happens next depends on the nature of the fault. On most applications, the ABS system disables itself if the ABS warning light comes on and remains on.

Air bag and abs lights staying on


If the Airbag light is on, it indicates that a electronic fault is stored in the memory for the airbag. You will need to have a diagnostic check done to pinpoint what the fault is, have it sorted out and only then can the fault be cleared so the light will go off. The ABS light also indicates a fault on the electronic side of the braking system. If the light comes on as you start the vehicle this indicates that there is an open circuit in the wiring or that the ABS control unit itself is faulty. If the light only comes on once the vehicle is in motion, this indicates that a wheel speed sender is incorrectly fitted or dirty and not sensing the ABS Rotor on one of the wheels. If a CV joint has been replaced, the joint may not have an ABS ring fitted on it.[front] At the rear the ABS pick up is fitted on the inside of the brake discs and must be fitted to the new disc when replacing discs.

Brake and abs lights stays on in a 2003 gmc safari wile driving after a small period of time. put new pads and there's no leaks in the calipers


Have the ABS Distribution Unit/Computer checked at the dealer.

NOTE: ABS Unit located under the vehicle, under the drivers seat. Listen to it with the vehicle running with no brake on... if you hear ABS motor running continuously, unplug ABS fuse in fuse block under hood to turn ABS motor off and be able to use vehicle in the meantime whether you decide to get the ABS fixed or not.. This will not affect brake operation, but will disable ABS feature. ABS and Brake idiot lights will remain on. No way to turn them off short of having the correct repair done. ABS Distribution Unit/Computer is very expensive part and requires expensive labour for replacement.

Buzzing noise coming from abs unit on start up, when he noise stops the abs light comes on ?


The light indicates a malfunction in the ABS (ALB) system. First, I would check your brake fluid level in the ABS unit (see pic, similar, I think). It should be between the max and min levels indicated on the front face of the reservoir. You should also check your regulator brake fluid reservoir to make sure the level there is correct. Dot3 or Dot4. If that is not the problem, then wheel sensors would be suspect, but that would be a Honda service indication.
Hope this helps you.75b78f9.jpg

ABS light comes on and stays on after about 5 minutes of driving


Sounds like an abs sensor or a pick up ring. The sensor is normally bolted to the hub assembly and the pick up ring is on the end of the drine shaft on the front or the back of the rear bearing hub on the rear. Bet you the garage who did your brakes knocked a sensor with a hammer and damaged the wire to one of the sensors.

ABS brake module sounds like a motor running and won't stop unless battery is disconnected. what is fix?


I would pull the fuse for the ABS hydraulic pump and then put it back in and see what happens. Don't ever recall a pump running. Dealer may need to hook up scan tool for diagnostic fault codes, DTCs.



Principles of Operation
The ABS control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.
The ABS control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.
The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; normal power assisted braking, however, remains.
Inspection and Verification — Scan Tool Communications Check
  1. Verify the customer concern by carrying out the Drive Cycle Test.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

  • Parking brake cable
  • Tire pressure
  • Tire size or mismatched tires
  • Blown fuse

  • Front anti-lock brake sensor (2C204)
  • Front anti-lock brake sensor indicator (2C182)
  • Hydraulic control unit (2C219)
  • Rear anti-lock brake sensor (2C190)
  • Rear anti-lock brake sensor indicator (2C189)
  • Yellow ABS warning indicator

Abs sensor light wont go off my 2005 polo


Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. ANTILOCK systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails to pass one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. The grinding noise could the the ABS pump or your brake pads could to worn to the metal backing and grinding against the brake rotors. I recommend a inspection soon for your safety.

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
