Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car

SOURCE: abs and engine fault light

If they are checking the system at the ECU and its telling them the sensors are bad, then you have a broken harness down stream of the ABS ECU. There has to be a brake in the harness to the rear wheel sensor(s). It is a brake in the harness or the end plug is not making good contact with the sensor contacts. Hope this helps.

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.

My ford focus 2001 has its abs light is on. The reason for it is my friend and i replaced the brakes but accidentally knocked out the actuator's left side part and brake fluid came out i bleed the...


The ABS light wont be on for the reason you have stated. One of two things probably happened. You have damaged the ABS sensor that goes into the hub ( hammering parts near the sensor can cause this) and it will need replacing( you will be able to follow the wire from the wheel arch down the suspension leg to it) or you have damaged the pick up ring it reads to generate the speed signal for the ABS computer (that will be located directly underneath the sensor on the shaft).

Usually if its the sensor that is damaged the light will not reset as it can see that fault immediately and if its the pick up ring the fault will clear and then return as you start driving and it sees the pick up ring damaged or missing. A garage with diagnostics should be able to confirm your fault or there are cheap scanners on ebay like forscan that can be purchased and used to read the codes yourself with a little bit of skill.

ABS light on all the time heated rear windscreen not working rev counter not working temp gaugenot working wiring checked out seeems ok COULD ECM BEAT FAULT AT FAULT!!!!


No i dont think so ,i think none of these faults are related ,ABS could be a sensor ring coroded on one of the wheels,nothing unusual with a UK reg car and all the corrosion and salt on the roads,a faulty dash unit could be the problem but the ECM no

The ABS light just came on what do I look at for the problem. I have a 2004 Jetta 2.0


If the light comes on as you turn on the ignition and stays on when you drive. This indicates that the ABS control unit is faulty or there is an open circuit in the wiring, most likely to the wheel speed senders. Look at the sensors harness's near the tyres as these some times come loose and get worn through by the tyre. If the light only comes on once the vehicle is motion, this indicates that one of the wheel sensors is not getting a signal due to incorrect space between sensor and ABS ring or a dirty sensor. If the front CV joints or the rear discs have been replaced the ABS rings may have been left off. Have somebody with a diagnostic tester check the fault memory as this will pinpoint the fault a lot quicker.

ABS light permanently on,but brakes working fine.local mechanic couldnt rectify because he couldnt find diagnostic point


the brake will work ok but abs most likely wont most common abs fault i can think of was the abs sensor air gaps to fix gently tap sensors with a hammer while watching to see if they move once gaps are set ok light should go off after roadtest

Jaguar dsc fault


DSC is your dynamic stability control, you probably went over something really hard and caused a fault, this is a normal response. If the fault stays on disconnect the battery and leave for five mins then reconnect, if you still have the same robelem your DSC module is faulty, it is located on the rear axel it is a block with an arm connected to the axel mid way on the axel.
Has nothing to do with yor abs the juddering was probably you driving over something which triggered the fault.
hope this helps
