Fault code reader?

bacn5 · 11-17-2009, 04:27 PM

Can someone help me find the link to the Motronic 2.4 jumper wire that allows you to read fault codes with an analog volt meter or LED? I know I seen it somewhere here in the past, but can't find it now.

It was a link to some European web site if I remember correctly. I don't need the ABS one.

Thanks in advance for the help.

I would like to know that as well. Could be real useful. Beats the 500 they want for a reader.

I have the procedure to clear a fault code at home!
I can post it later today.
But I do not know of anyway of reading the fault
without a reader!

I have the GS-911, and it allows you to read and reset all fault codes from about any BMW. $299 from The Beemershop in the US.

TM, are you happy with the GS-911? Does it work well and such? Any input would be welcomed!!

TM, have you had the opportunity to "park" the stepper motors yet when doing a throttle synch?
I've read that on the Hexheads, GS-911 will do that.

This link showed photos indicating the proper pin to wire directly to on the Motronic 2.4. (It was something like pin #18) The pin spot is currently empty on the R1100S connector.

The author runs a wire to the empty pin and connects it to a new female pin prong. The other end of the wire terminates back by the standard connection area under the seat.

To read fault codes first you connect an analog VOM meter, or LED light, to this wire. Next you ground it for a few seconds. The VOM meter or LED will move or flash indicating a fault code number.

This will read faults in the sensors and what not connected to the Motronic.

This is a link to a similar site outlining the Motronic 2.2. It mentions some guy in Holland who did it on the 2.4.

I don't have a hexie and I have my K for too short to have done maintenance on it, so I couldn't tell you about that. All options/features are available on the site I linked to though.

Yes, it is extremely easy to operate. Just plug it in, start the software, pick your bike model and of you go. On my R11S non-ABS options are a bit limited for obvious reasons, as the only thing there is look at is the Motronic. On the K though, I can see just about every electronic system there is and if it is doing the right thing. It even tells me when the valves need to be checked. Very useful when doing your own maintenance. Its very easy to trigger an ABS fault for instance when flushing and bleeding the brakes and instead of going to the dealer, just reset the fault and go. You can also read all sensor and operating parameters when the engine is running, which can be useful for diagnostics.

Main reason for me was to be able to read and clear faults though.

Do you mean it tells you when a certain mileage has been reached for valve adjustment or is it more intuitive than that? 300 is not as bad as I thought. Will it do the HP2S.

Found a similar post... Scan down until you see the post with photos:

Now we just need to find a source for new female crimp pins.

It will just plainly tell you at which odometer reading a valve adjustment/check is required. No room for misinterpretation. This information sits in the ECU. I have no idea however how it is updated, as it is not part of the service information section.

Service information is cool too, if the bike supports it (HP2S should). You can set an odometer and/or date at which the display of your bike will tell you it needs service. This can be set by the GS911, so if you do your own maintenance you just set it to your next planned service and the bike will tell you when it is that time again.

Of course nothing you can't keep track of in your good old logbook, but still.

I just bought a GS-911, the "enthusiast blue tooth model". So far, I can't get the Blackberry to stay synched with the unit, so I am relying on direct USB connection. I'm sure I'll get it figured out, but haven't put in the time. I need to do the stepper motor idle adjust tonight and will let you know how it goes. The documentation is pretty skimpy, but so far it's pretty easy to figure out (Bluetooth aside). I think you don't actually synchronize the throttles in the normal sense. It's just a command to send the stepper motors through their full range to figure out where "closed" is.

And yes, they're advertised to work on the HP2S.

Well, that was easy. I finally figured out the bluetooth too. Not all the functionality is available from the BB app, but some real-time data is available. It looks to mostly be good for fault diagnosis on the road, but if you have a small notebook you carry anyway, I wouldn't bother with blue tooth.
The PC interface, on the other hand is slick! The idle synch was just what I thought, it puts the steppers through their range of motion to hit the stops and determine where fully closed is. Not sure if the factory interface actually does more?

And it does have the settings listed for the HP2S.
