Title: ABS fault clearing
Post by: alexis291 on March 14, 2018, 06:32:45 PM
Greetings...

A simple question I hope. If I have an ABS fault (lights are flashing), does it clear automatically once the fault is rectified or do I still need to go through the reset procedure?

The answer most likely depends on what year and model of bike you have.

Most codes need a reset, sensor distance will reset everytime you turn the bike off and back on again - at least for my 1991 K100RS

Clearing faults is slightly different for ABS I, and ABS II.  Be sure you are usuIng the correct procedure for clearing ABS II which is what should be on your "95". I don't have them memorized. If you have a weak battery that needs replacing, you will get a fault every time you turn on your ignition,  regardless of if you have cleared your faults, until you replace the battery.

Thanks all for the replies. I’m sure the lights are flashing because my front sensor is damaged. I had to be pretty brutal with it to remove it from the fork leg when I changed the seals last week. It was seized in situ. Fortunately I have a replacement sensor so will see if the fault lights go when that is fitted, if not I’ll be trying the reset procedure. Hopefully not 200 times though Johnny...

It will also give an error if the gap is out of spec so be sure to measure the distance between the sensor and the ABS ring. 


The spec is 0.50 - 055 mm for a floating front disc or 0.60 - 0.65mm for a fixed front disc and 0.60 - 0.65 mm for the rear wheel - at least it is for the K100RS I have with ABS 1, it may be different for ABS II models

Thanks. The gap was wrong but correcting it didn’t stop the lights flashing. I will fit the replacement sensor tomorrow but we have snow forecast so might not be test riding for a couple of days.

Post by: alexis291 on March 16, 2018, 09:13:14 PM
No because I’m 99% sure it’s the front sensor, after I had to brutalise it to remove it.

Pretty sure you still needs to clear it. Pretty simple to do.

Post by: johnny on March 17, 2018, 09:55:36 AM
bizzaro is correcto...

will need to clear the code from the blue connector under the seat or yourn lights will continue to alturnait... so may as well getts familure with that blue connector...

Hope this helps. Make sure you use the instructions for ABS II.  They do vary slightly.

Have now fitted the replacement sensor. Not sure if it will work yet as it came off an LT and the connector was different so I fitted the plug off my old sensor. Physically it’s the same size. My old sensor was open circuit, new one about 130ohms. Then fixed my broken abs reset switch (now working because the lights go solid when pressed) and went through the reset procedure maybe 20 times. The lights still flash but I don’t know if they will clear when I ride the bike after the snow has gone...

The lights won't stop flashing until the bike moves.  It doesn't take much just a couple feet.

Shouldn't last too much longer.  We still have about a foot on the ground with little opportunity to melt in the foreseeable future as well.  I'm figuring April for the first ride this Spring.  Could be worse, though, Laitch probably won't be out until June. :musicboohoo:

To check your ABS would it not be possible to put the bike on the centre stand and run it in gear the prescribed distance. :dunno You wouldn't have to rev it's head off and it might save future disappointment when the snow clears.

What about the front wheel sensor?

One of the system checks is to see if both wheels are turning at the same speed.  Bike has to be moving across the ground to get it.  Only needs to move 5-6 feet to pass the test.

Not necessarily.

If one line is marked across the side profile of both the front and rear tires with Wite-Out then both lines synchronized in their vertical positions, it should be possible—after a few hours or days of practice—to become adept at rotating the tires at precisely the same speed. Bingo!

What else is there to do when weather keeps you from riding?

So here, in the quest for perfection, is a tidied up update...

First of all, the snow has gone and I am mobile again!

I have now cleared the fault with my abs system and what I did may be of some help to others with the same problem. I worked my way through this excellent article (http://www.motobrick.com/index.php/topic,1631.0.html) and confirmed that the front sensor was the problem (three pulses, tested with an analogue voltmeter). I then removed the abs brain connector and check the resistance of the front sensor I had fitted, which was within spec. I did wonder if this might have been the problem because the sensor I used is from an 1100LT and I had to change the connector over to fit my wiring loom.

I then used a variation in the procedure published elsewhere on this site in that I pressed and held the abs reset button after turning on the ignition, not before (as described in the article linked to above). I'm not saying pressing the switch before doesn't work but turning on the ignition first worked for me. More Voodoo ...?

Also useful is to know that once the fault has been cleared (ie the normal mode), the ABS lights flash together and not alturnaytely so this is how you can tell it's now ok rather than having to go for a ride.
