Abs light on how to reset - 1985 BMW K 100 RT

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

The ABS light only comes on because of a fault. You need the ABS control module scanned for the code that set when the light comes on. There is no RESET

The ABS light on your vehicle will self-reset, once the condition causing the light to illuminate is rectified.
Reasons for the ABS light coming on are:

1. Worn brake pads;
2. Worn calipers (beyond tolerance);
3. Defective ABS unit;
4. Low brake fluid level;
5. Defective master cylinder;
6. Brake fluid leak.

It is important that whatever condition is causing the ABS light to illuminate is corrected as soon as possible, as it indicates a potential hazardous condition exists with your vehicle.

new abs and speed sensor fitted light still on do codes have to be cleared

Check speed sensors on the front.Clean them with a non chlronated brake cleaner this most likely the problem.

ABS light on - means your Brake ABS system is not working.
Some autoparts stores, like AutoZone will scan you car for error codes. I recall that they can scan for engine and chassis codes, like the ABS system. They can also reset the light.

The bad news is that when the ABS light stays on, there really is something wrong with your ABS. You should get the car scanned and an estimate for the repair.

the ABS light resets itself every time the key is turned off and on, it is self testing and will only turn the light on when there is a problem in the ABS system, worn out brakes don't cause the ABS to come on, if the light is on the system has a fault present and it must be tested with a factory system scanner to determine the source of the fault or at least the area that is causing the problem, that can be one of the four wheeel speed sensors, a defective ABS hydraulic control unit and sop on.

There are dedicated scanners for resetting the ABS light.
