What causes ABS light to stay on continuously


You will need to get the fault codes read as the fault can be any of the following

wiring fault to any of the sensors
abs ring lost teeth or read fault
abs controller self test fault
abs pump fault

2003 Durango abs light won't go off nothing is wrong no codes are thrown


If that light is on there is a code, you did read this with an ABS capable scan tool? an engine code reader tool will not read the ABS control module

I have a 2007 they suburban taho and the stabill track light is on


The Stability System is part of the anti lock brakes ! The place to start is
Diagnostic Starting Point - Antilock Brake System
Begin the system diagnosis with Diagnostic System Check - Vehicle .The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
This Is going to be Greek to you probably ! This is where a up scale scan tool is needed , or a factory one ! Your going to need to have vehicle scanned for DTC'S diagnostic trouble codes ! Is the ABS light on as well ?
A sample of DTC'S
DTC C0186 00: Lateral Accelerometer Circuit

DTC C0186 5A: Lateral Accelerometer Circuit Erratic
DTC C0196 00: Yaw Rate Circuit

DTC C0196 5A: Yaw Rate Circuit Erratic
DTC C0252 00: VSES Sensor Uncorrelated
The Vehicle Stability Enhancement System (VSES) is activated by the electronic brake control module (EBCM) and calculates the desired yaw rate and comparing it to the actual yaw rate input. The desired yaw rate is calculated from measured steering wheel position, vehicle speed, and lateral acceleration. The difference between the desired yaw rate and actual yaw rate is the yaw rate error, which is a measurement of oversteer or understeer. If the yaw rate error becomes to large, the EBCM will attempt to correct the vehicles yaw motion by applying differential braking to the left or right front wheel.
This is a problem you should take to the dealer or a ASE certified repair shop ! Or you can try to reset the system by disconnecting the battery cables an touching the cable ends together for 60 seconds ! But if there is a real fault in the system ( bad sensor ) The light will come back on ! Maybe not right away ! A couple of days or weeks etc....

How do I obtain a list of the ABS fault codes/ definition and diagnostic procedures


Try this: https://www.youtube.com/watch?v=Tf9ygGnJ-6o But there is not a lot of information on brake systems because of the liability and royalties that are involved.

Abs on vr commodore light stays on solutions


Error logs are a great thing. They will help you find intermittent problems and start you off in a general direction of where a problem could be. There is a great level of detail on the justcommodores site on checking error codes logged by the engine management system, but this does not detail anything about the abs system. The abs warning light is not as common as the check engine warning light. Reading through the posts, I haven't found any detail on checking error codes logged by the abs system.

So here it is. For those of you familiar with checking the engine error codes, this procedure is so simple its not funny.

Basically, to check the engine error log, you bridge the 5th (ground) and 6th pins in the ODB connector under the steering wheel.

To check the ABS error log, using the same trusty calibrated paper clip, you simply bridge pins 5 and 12 of the connector.

To find pins 5 and 12, start at the top left hand corner. That is pin one. Going to the right, you count pin 2,3,4 etc. Once you get to the end, jump back to the start of the bottom left level of pins and keep counting. Pin 5 is about halfway along the top row, pin 12 is a little left of the middle in the bottom row.

Reading the error codes is the same procedure (counting the flashes), except now, the ABS light flashes (as opposed to the engine light when checking the engine codes).

The ABS log also uses code 12 firstly, with any errors logged shown after that. If no errors are logged, the 12 will flash again.

Error codes for the ABS error log (VR/VS) are as follows:

12 Diagnostic system operational
21 Right hand front wheel speed sensor fault
23 Right hand front wheel speed sensor continuity fault
25 Left hand front wheel speed sensor fault
27 Left hand front wheel speed sensor continuity fault
28 Wheel speed sensor frequency error
31 Right hand rear wheel speed sensor fault
33 Right hand rear wheel speed sensor continuity fault
35 Left hand rear wheel speed sensor fault
37 Left hand rear wheel speed sensor continuity fault
41 Right hand front inlet solenoid valve circuit fault
42 Right hand front outlet solenoid valve circuit fault
45 Left hand front inlet solenoid valve circuit fault
46 Left hand front outlet solenoid valve circuit fault
55 Rear inlet solenoid valve circuit fault
56 Rear outlet solenoid valve circuit fault
61 Pump motor relay circuit fault
63 Valve relay circuit fault
71 ABS control module internal fault

The above guide has been verified on a VR/VS. Checking the error log on all models prior to VR/VS is the same for the engine log, and I would assume that the same can be said for the ABS log, would be happy if someone could verify this for me.

abs light on means some fault codes stored in your car,

Fiesta duratec 2005 Abs warning light on


Whenever the ABS module turns on the ABS light in the dash it is to alert you to the fact that a fault has occurred in the ABS system and the control module has turned off the ABS brake control, you now have regular non ABS brakes. The waring light will stay on until the fault is corrected. Since a large number of problems would cause this you must get the control module scanned to retrieve the fault code that was set in the control modules memory when it turned on the light. Once the fault code is known the process of diagnosis and repair can begin.

Abs light stays on I have put new brake line on new calipers because they were sticking causing brakes to get hot, thats all fixed but light still stays on.


the ABS light is on because there has been a fault detected by the ABS module. It has nothing to do with the actual braking system.

The ABS module does a self check every time you start the vehicle. If it detects a problem during that self check the ABS light will stay illuminated and a code or codes for the fault will be stored in the ABS module. Scanning the module will allow you to pull the codes and proceed with diagnosing why the fault is occurring.

The most common source of ABS problems is bad wheel speed sensors or broken wires to the wheel speed sensors. Again pulling the codes from the ABS module will narrow down the possibilities.

Once you now what codes are present post them and we will be happy to assist you further.
