So i bleeded my R1100GS brakes, but ABS gives error after that (two light flash separately if i turn the ignition on). They worked OK bofore, and i didn't do anything except bleeding the brakes like non-ABS motorcycle as i was told to do.

Brakes work normally at least... But not ABS.

What could be the cause of that problem?

Does ABS sense there's some air left in the brakes? Or some air got into ABS unit?

Or just ABS needs reseting?

Or...?

I don't have ABS on my bike - but don't you have to bleed the system at the ABS unit, as well as at the calipers?

IIRC, it's only the servo systems you need to do that with Mike.

MArgus...I suspect it's more to do with wheels spinning and upsetting the abs sensors.....try a reset and see if that cures it.
 
Did you remove the wheels to avoid oil contaminating the discs'? Check the ABS gap - the gap between ABS ring and sensor.

There should be two feeler gauges [go/no go] in the tool tray. If the supplied feeler gauges are missing the gap should be - .45/.55mm - the gap being adjusted with shims obtainable from a dealer.

You'll need a T25 torx drive for the sensor retaining bolts.

Noupe, didin't remove the wheels, just cleaned them well after bleeding. The gaps were quite OK if i measured before.

Well, i'll remeasure them today too. :)

ABS resetting

-------------
The following procedure can also be used. It is useful to carry a short length of wire stripped at both ends.

Turn ignition off.
Remove pillion and rider seats.
Locate the 3 wire plug by the toolkit and remove the blue termination. (It's for diagnostics so is not connected to anything).
Insert one end of wire into the *middle* socket.
Clip the other end firmly to ground.
Turn ignition on. Note that the two ABS lights continue flashing alternately.
Hold ABS button down for 8 seconds. The bottom ABS light should stay on, the top one off.
Release the ABS button.

If the reset is successful, both ABS lights come on.
If you didn't count to 8 or your ground is not good, then the top ABS light stays off. Start again and/or try pressing the ABS button before turning ignition on.

Turn ignition off, remove wire, reconnect plug and refit blue termination.

Does anyone have pictured manual how it's possible to do it - i don't know what it means by one is the three-wire plug, which one'n'where? :confused:
 
Aah, found the pic:

It's in Netherland's :confused: , but at least i know which is the 3-plug one and now i know the cause of my ABS error too - i disconnected the plug for taping it while i taked off the seat during my brake bleeding operation, dunno if i turned the ignition on too meanwhile, but i think the ABS needs reseting anyway.

Cheers, Margus :beerjug:

It's only a cover ? - you can't disconnect the plug unless you cut the wires -
also check your ABS switch on your instrument panel is actually working ( they corrode inside the switch) , otherwise you can't re-set the ABS ;

You do need to bleed the ABS modulators if you've had the system apart, they bleed in the same way as a caliper, the nipples are on top of the modulator -

But bleeding the brakes has nothing to do with the ABS working - you could have no brake fluid in the system and the ABS would still work - i.e. the lights would go out -

Am... Dunno, i mean "plug" as there are two sides connectible under the seat, like they're disconnected on this pic:

It's called diagnostics plug, if i guess it right.
I think i may have put ignition on while that pug was disconnected? Or it shouldn't be connected originally? :confused: I think it was and all worked.

The ABS switch works OK on the instrument panel - i use it often.

You do need to bleed the ABS modulators if you've had the system apart, they bleed in the same way as a caliper, the nipples are on top of the modulator -

OK. I'll bleed the modulators too, BUT - what would be the correct order then - to bleed brake calipers first and then modulators, or via-versa order, or doesn't matter which order to perform?

But bleeding the brakes has nothing to do with the ABS working - you could have no brake fluid in the system and the ABS would still work - i.e. the lights would go out

Youp, the lights flash separately on the moment i turn the ignition on. So looks like the ABS reads some error mometarely if it's powered up. So i thought it could be some random error maybe due that diagnostics plug i touched a bit if the ABS works OK even if there's some air in the system.

I'll try to reset it first, let's see if it helps. If not, then i'll search some other causes...

Cheers, Margus
 
The black socket ( diagnostic socket) pulls out from the blue "plug" -

The blue plug is just a cover/holder - there is nothing electrical in it - if you release it, it will just fall off -

Haven't a clue what the other wires are, the ones attached to the diagnostic socket and the earth attached to the frame .

Others are home-made diagnostics tool :)

I just looked for the pic to find a reseting stuff.

So i must put 20cm wire one end into middle hole of the plug (it has 3 holes) and other end into the ground, then turn igintion on, hold ABS switch on for about 10 sec, release it, and it should work then if it was "reseting-need-error", right?

As good as earth (ground) as possible --

if no faults, that should clear it - sometimes needs doing a couple of times , you'll also hear the relay " double click" when it resets -
 
Where would I find this blue covered plug on an 02 Adv?

you haven't got one - it's only on the 1100 , not 1150 -

you have to look at the round socket attached to your air box for the same type of thing - but it all depends why you wanted to find the "blue" socket ?
 
I want to reset my ABS.
Hasn't been working for about a week (alternate flahing lights). No work done on the bike, but happened after a days turning it off continually trail riding. No crud in there, and gaps are fine.
Hopefully just needs resetting.
(02 Adv, single spark, no servo)
 
Further searching found this:

"Here's a slightly more extensive procedure I found.
I've done it like this and it worked. So I think 1 minute is overdoing it a bit

1) Turn ignition off.
2) Remove the seat.
3) Locate the diagnostics plug behind the battery.
(It's for diagnostics so is not connected to anything).
4) Connect an end of wire to the brown/blue wire pin .
5) Clip the other end firmly to ground.
6) Turn ignition on. Note that the two ABS lights continue flashing alternately.
7) Hold ABS button down for 8 seconds.
The bottom ABS light should stay on, the top one off.
Release the ABS button.
8) If the reset is successful, both ABS lights come on.

If you didn't count to 8 or your ground is not good, then the top ABS light stays off. Start again and/or try pressing the ABS button before turning ignition on."

I also need to look at my brake light, as it appears a defective bulb can bugger up the ABS.

Apologies for not doing an extensive "search" before posting.

;)
 
Steps 1 to 8 above sorted it.

Bet that procedure isn't in the owners manual, thank you internet!
