Try diconnecting the battery for a minute or so, then reconnect it. the computer should reset itself, and hopefully the light will go out.

SOURCE: what would cause the fault

It is most likely the abs sensor is dirty or bad,It won't affect the operation but it will prevent the abs feature from working.You can have it checked at any brake shop.Some will even do it for free.

Prius warning lights abs pressure brake


abs concern. abs light. also, red brake light. is this correct? drive axle was replaced. testing for abs codes can lead to a pinpoint test.
once codes are read, there may be a specific area indicated to run tests. since the wheel hub area was where the recent work was performed...i suggest looking at the abs exciter ring for the wheel speed sensor.if the teeth are broken off , and or smashed or flattened. the hub, or the ring attached may need correction. there may also be a speed sensor wire and sensor concern after working in that area. inspect the sensor, its wires, and the connectors that attach it to the wiring. take the result of the code check, pinpoint test, and physical condition of the parts into mind, and decide. report your findings. you will need a good quality DVOM test meter to perform electrical tests. and guided diagnostic from the applicable service manual.

95 Regal Custom, ABS code #95 brake switch circuit and no brake lights. Replaced SLS still no change.


Check the brake light switch (location pedal) unplug the switch & bridge the wires & if the brake lights come on the switch is faulty. all you are doing by bridgeing the wires is bypassing the switch. What is SLS?

Abs light brake light on not shifting


look under the truck at the ****** and check the wiring to the sensors if good may be a bad sensor,also check the wiring and connections to the abs wheel sensors [ located from frame to the hub behind the rotors ] the abs also acts as speed sensor if problem was with an abs sensor at the[ hub] wheel usually set the brake system to normal power brakes [if u hit brakes hard will lock up or skid wheels] with the abs light coming on if the speed sensor at ****** malfunction can and usually causes shift problems

I would recommend checking for diagnostic trouble codes in the ABS system. If there is a diagnostic code C0265 set, then you're most likely looking at an ABS computer replacement. This is a common failure on these trucks. GM calls this computer an EBCM, or Electronic Brake Control Module. This is the controller for antilock brakes and is mounted directly to the ABS pump motor assembly. Last time i checked, these things were going for about $900 at the dealer.

Hello,
There is a ground wire connected to the engine block. Look for it on the back passenger side of the engine towards the top. Remove it and clean the connection and the wire connector and replace. Sometimes they get real bad and throw the ABS light on. Sometimes a brake light out can throw the ABS light on.

  • You said you rebuilt the ABS module, do you have a short in it you are missing? The bulletin for this originally suggested to replace the module and was corrected because the ground itself was the major offender.
  • Try to reground the EBCM. The code 0265 says "loss of communication with the brake module" The EBCM Ground is located on the frame beneath the driver's side door. If multiple grounds are found in this location, the EBCM ground can be identified as the heavy (12-gauge) wire. Clean the area, front and back, using a Whiz Wheel.

  • Install the ground, then the washer and then the bolt to the frame. Important: It is important to use the bolts, washers and nuts specified in this bulletin. These parts have been identified due to their conductive finish.
  • Install a washer and nut to the back side of the frame.
  • Tighten the nut to 9 N·m (79 lb in).
  • Cover the front and back side of the repair area using Rubberized Undercoating. An additional check can be made to ensure a good connection for the Battery Cable to Frame ground.

check fluid levels and if that is not the culprit then check sensors by unplugging them and using a voltmeter attach the leads to the wire ends and rotate tires and if voltage is supplied than the sensor is ok
