R 1150 GS MJ99 GS911 USB Gen2// No connection to ABS

[h_c_82]

Hey,

I just purchased a GS911 USB (the red one). I cannot get a connection to my ABS and thus cannot read or clear faults. The Bike is a 99 R1150GS. It is advertised that this features are available (actually the reason why I bought it). Can anyone elaborate on this?

Further more I have a question about the idle position switch. It turns out that the switch is set "on" only when I lift the throttle and "off" when the throttle is closed (at 0,64°). In my logic it should be the other way round. Am I missing something here or is this normal?

GS911 Software Version is 1711.3 (Data Version 9.30)

Thank you in advance for any help!

Holger

Ah, and I will post the Autoscan as soon as I get back to the workshop. I left the tool there.

Hi h_h_82, and welcome.

The first question I have to ask is whether the ABS on your bike is actually functioning as it should.  From your first post it would appear that it is non-functional, thus the purchase of the GS911.  If it is non-functional, it is possible that the controller has burned out, in which case you will not be able to connect to it.

The idle switch is a bit of a catch 22.  For it to be adjusted, the switch needs to be on.  However, when it is out of adjustment, the switch is off.  I will be doing a short "How To" to show to set up the throttle body and switch in the near future.  In the meantime, just follow these steps.

Back out the butterfly stop screw on the LHS TB until the butterfly is completely closed and the butterfly stop is not in contact with the screw. 
Connect a multimeter to pins 1 and 4 of the TPS
Adjust TPS to give 0.25V on the MM and tighten the screws, ensuring that you maintain the 0.25V. 
Now turn the butterfly stop screw in until you achieve 0.36V on the MM.
Lock the butterfly stop screw.

If you now hook up the GS911 you will see that the idle switch is on and the switch is correctly adjusted.

Thank you for your reply.

It actually is non functioning. I took it apart in the meantime and found that the clutches were sticking (8,5Amps Current drawn while activating the motor). I fixed that and am now reaassembling the ABS unit. I doubt that the controller (you mean the ECU of the unit?) has burned out since I am able to delete faults via the diagnostic pins (grounding pin 2) and it worked actually fine until last week when the self test failed (most likely due to the sticking clutches).

regarding the TPS. It was already set the way you explained it to me. I did that already. When I do the TPS test it is also in the green range, So I assume that the TPS is set correctly. It is just when the engine is running that the switch turns off and goes on when I open the throttle. Very strange.

As said Autoscan report will be attached throughout the day.

Thanks

And I am of course using a OBD2 to 10pin Adapter cable. Can this be the reason why I dont get connection to the ABS?

Hello Holger

I think the reason will be the communication to this ECU.
Engine > K-line
ABS uses blinkcode and needs the "3-pin" adapter to communicate

[h_c_82]

Really? I thougt only the r1100 with 2.2 Motronic have this 3 pin connector. I can delete ABS faults with grounding Pin 2 on the diagnostics pin.

Any of the guys from Hexcode on this forum that can give me an answer?

OK, you have the pre-servo assisted pump.

Yes, if the clutches get stuck the unit will not initialize and you will not be able to talk to it.

And you are correct.  The older 1100s use the 3 pin connector.  Your bike does not have one.

 "I can delete ABS faults with grounding Pin 2 on the diagnostics pin."

If that is possible, you also can read the blinkcode : http://www.powerboxer.de/bremsen/540-4v1-abs-ii-fehlerspeicher-auslesen

ABS with K-Line diagnosis will never delete faults by connecting PIN2 with ground.

[h_c_82]

Well mine does. At least with the procedure grounding pin 2 pressing abs button ignition on etc etc...as described on Powerboxer.
And yes I know that procedure to read the blink codes also. But I bought a GS911 because it was advertised that it can diagnose my ABS. But it obviously can't at least not until now. Thats why I am asking for help here.


So Jughead, what you are basically saying is that you cannot connect to the ABS while it has not initilaized (when does it initilialize?). And it does not initialize while it has a fault. So you cannot connect and clear that fault because it has the fault. If that is really the case then the GS911 is useless at least for the ABS because the only time you really need it is when you have a fault and want to read it and clear it.
I find that hard to believe...

[Jughead]

Compare it to not being able to find your spectacles because you cannot see without them.

The ABS ecu must be alive and able to give you the fault code.  If it is not alive you cannot communicate with it.  Try running an Autoscan on your bike with the ignition switched off, or with a completely dead battery. Same thing.  Your GS911 is completely useless without something to talk to.

[h_c_82]

  Good comparison. I see what you mean but when the ABS lights are blinking fault there must be something (In that case obviously the ABS ECU) to tell them to blink. So it cant be dead. Who else would get the lights to blink.

Anyway. I repaired the ABS unit (hopefully) and get it back into the bike. Clear the fault "manually" and start it up as usual and try it again. Then we will see.

[h_c_82]

ABS is ok now. Cleared the fault "manually". Self check passed. Still no connection to the ABS. So this was not the problem. I am beginning to think that my Adapter Cable is the problem because it obviously isnt the ABS or the diagnostics pin on the bike and I doubt that it is the GS911. Only thing in between is the Adapter cable.

Is your adapter cable one you made up, or the one Hexcode sell?
