K1200LT Abs woes again!

Hi ,
I have a 2000 k1200lt for a while now the abs light has been flashing left right left right.The brakes work just fine so Ive continued to use it and just be mindful of the lack of abs.
However It disturbs me how much the valeu of the bike is affected by the abs lights being on.
I took it to my BMW dealer who scanned it and told me the abs unit had gone bad , that a new unit would be £2000 and so the bike was beyond economic repair, he refused to elaborate further.
Obviously I was unsatisfied by this so I decided to have a go myself.
Firstly I bought a hexcode 911-gs, hoping that this would at least diagnose the issue and hopefully clear the codes and turn off the light.
I connected the gs911 and was able to scan the engine codes etc so it was working and connected correctly , but when I tried to scan the abs or clear the codes or anything to do with the abs it retured."failed to read fault codes no response from controller"
Now I dont know what to do, should I consider that the whole abs control unit is bad? and search for a replacement.Or is there another course for me to take.Im unwilling to order another part and start taking the bike apart without better proof that the unit is bad.
Thanks in advance for your helpK1200LT Abs woes again!-hexcode.jpg

Re: K1200LT Abs woes again!

If the 911 unit is not reading the controller unit, try popping the connector off and back on again and check fuses. If you still get no communication then the controller is toast.

The OP (jimbobillybob) posted he had a year 2000 model so this is ABSII - hence only an ABS-modulator from 1999-2001 (USA) or 1998-2000 (Europe/Canada) will work.

A 2005 model like yours could replace a modulator in any K1200LT 2005-2009 (USA market).

OT: Don't servo-brakes have pump and ABSII "just" modulator? But guess system has to modulate the pump pressure, so it perhaps has both

In my opinion, it is more a matter of wording (or interpretation) as they both implement the concept of ABS-Modulator. However, the IABS (2001-2009 for USA) also have electrical servo brakes built into the ABS unit (booster if you want...).

Re: K1200LT Abs woes again!

Thanks
jzeiler , you were quite right , I cleaned the plug and socket with a little wd40 and it read perfectly 2nd time of askinking, and cleared the fault, I took it out and when traffic allowed I broke sharply to induce a skid, the abs kicked in and worked perfectly .
Cant tell you how pleased I am.
Thanks everyone for there response.
