1150 GSA ABS Failure !!!!!

So that's not a 1100 to 1150 change then? The underseat plug that is.

Well as he just said he's got an 1150 with the small underseat plug I guess not ;)

From what I understand the early 1150's (up to 2002-ish) got the 1100 ABS2 with the small diagnostic plug and the two ABS lights. From 02 they got servo ABS with the big round diagnostic plug on the airbox and 'ABS' and 'Gen' lights. I think it's certain that if he's got the little diagnostic plug, he's not got servo ABS. He's also got full braking while in a fault condition which you don't get with servo ABS do you (I'm assuming he might have mentioned if he only had residual braking)?

But wadoo I know, I've got an 1100.

If you can make up an LED to use on the diagnostic connector then you can find out why the unit believes it has a problem.

The pdf is this link is very useful as it shows the connect pin designations clearly.

The IBMWR link shows how many "off" pulses of the LED relate to what problem.
If you have 5 off pulses then it's the battery voltage concern.
There is a work around for the battery problem if you're wanting to eliminate the problem completely, it involves adding a relay so that the ABS only powers up after the engine is running and avoids the low voltage problem.

I'm currently battling a 4 pulse, rear sensor, fault but can't get the unit to reset with any of the methods described in these attachments. So I may be looking at conversion to non-ABS soon.

Good luck!

Did you get your abs sorted?

My 2000 1150 has also started failing, 2 ABS lights flashing alternately.
It only started to do this a few days after changing the back brake pads, I'm wondering if this has anything to do with it?
I can do the reset by grounding the wire in the plug above the airbox, and then get the lights to flash together, however when I ride the bike away just after startup, and get the "kerklunk" sound as normal, the lights flash alternately again and I have no ABS.
I can reset it but its the same story over again...

Just wondering if you got yours sorted and if it was just the battery.

Not believing in coincidence and given that it started after changing the rear pads, I'd carefully check the rear abs sensor and wiring.
 
If you have an ABS fault wouldn't your ABS light stay on.... just for my own peace of mind as I'mall worried now that my abs doesn't work... as I have never heard a clunk. I have an 04 GSA with Servo... and I can brake so I'm guessing everything is fine... even if there is no clunk!?

All 1150 models have the round diagnostic plug regardless of servo or not.

rest your weary mind - Servo models don't make the "piston" check clunk.
 
Thanks steptoe! I also managed to conduct my own highly scientific test... I belted it down the drive way then hit the brakes hard. I get skid marks for about a foot... then nothing for a foot.. then skid marks for a foot... etc. Looks like they work! :thumb2

OK, you got some skidmarks, but does your ABS work. :D
 
This is my first abs bike and I didn't know that abs operation was part of the mot test. I was impressed with the mot testers technique - raz down his gravel covered car park and stand on the back brake :D
 
I didn't think it was ? - I've never had the abs tested on any bikes.

Surprised me too but he did the usual mot model search thing on his computer and said 'oh its got abs - I have to test it works' :nenau Didn't bother me but I don't know how you'd get on if you'd done an 'abs removal' as the dvla computer would still report it as an abs bike?...
 
ABS

How can atest on gravel be a proper test>? only thing that will test is how much bottle the testers got, what happens if he drops it?. Find another MOT man in future mine's never been looked at even though it dosent work.

I didn't think doing a wheelie was part of the extended MOT test I needed to import my 'bike from Germany.

Didn't stop the nice test bloke from having 'his' fun.:rolleyes:

At least he didn't test the ABS like on Matt's bike..
 
Perhaps I didn't make myself completely clear - he did a full brake effort test on his rolling road jobby but the first thing he did was test if the ABS operated by riding it and locking the back wheel. I'd have thought that a loose surface such as gravel was ideal for this (it's certainly how I experimented when I first got the bike to see what the ABS felt like) :nenau

As a bike garage he comes highly recommended and he knows his stuff (race prepares Ducati's) - he's not a BMW guy but he's my nearest test station and is 'reasonable' with his MOT's (i.e uses some common sense where required) so gets my business once a year.
