 Posted: Sun Oct 01, 2006 10:43 am Post subject: Code Fault 1111 |
 |
|
I made diagnosis box for Motronic. Today, I checked for Motronic on my K1100LT. But I encoutered the following code. 
| Quote: | | 1111 CO potentiometer not detected with Oxygen sensor disconnected |
I guess that...
"CO potentiometer does not work" or "Each connector has loose connection" Is this correct ? Any comment?
My K1100LT ('92) is Non-Catalyser model.

If you have a NON-CAT model, you should have the CO potentiometer connected. You can disconnect it and check the resistance of the pot.

Today, I have checked the resistant of the pot. Then I found it out the pot does not work fine.
Each value is as follows.
A-C 1.051K ohm / A-B 1.051K ohm / B-C 0.002 ohm
I deduced that pot has loose connection. And I tried turn and re-turn pot. After do that, the digital multi-meter shows correct value A-B 640 ohm and B-C 409 ohm. I hope these values is non problem.

It appears that B & C are shorted together.
Try rotating the pot to one end, take your readings, then rotate the pot fully to the other end and do your readings again.
Effectively the total resistance should be seen across A-C.
(in this case 1.051K)
B will return a reading proportional to how far it has travelled between A & C. (EG, if the pot was set so that B was about half way thru it's travel, you would expect approx 500 Ohms between B and the either A or C.
Obviously if B is wound to one extreme or the other, you would expect zero Ohms, or there abouts Between B one of the others and the total resistance between B and the other.

This is not a genuine BMW Tester. It probably does what it states however I believe it should read....
"Check and YOU CAN adjust the throttle flap potentiometer"
for a cost of $5 Aus, you can build your own with the info mentioned above.
You don't need an expert to do it either

John,
Looks to me like someone is making a lot of money putting my LED in a plastic box with a switch.

The key word here is "Genuine" I guess it is genuine because he made it himself, and the fact that BMW don't make that exact item, he can call it that. but I wonder how long it will be before the BMW Nasties begin to swoop.

I was told by my trusty wrench that I had a Fault code 7 on my 96RS. That the control unit would have to be replaced for 2K. This happened as a result of me not seeing a slick wet spot in a parking lot. My 95RS has been done harder and no problem. Is there any way around me this.

IF you really have a solid Code 7, you can try to find a Hydro Unit with a mechanical failure and just swap the Control board from that one to yours.
Have you verified his diagnostics?

Hi Mick
A BIG thanks from Sweden too.
Just what I neededm has a -94 K11LT that will not rew abowe 3krpm, regardless of gear and torque.
Was wery close to ask it there are any adepter to OBD II, but there are no need for it now. Or are there any adepter to OBD II?
Even if I can't ride it at the moment ( no spiketyres ), I can always check the codes.
/All the best

Sven-Erik,
That sounds a lot like low fuel pressure. Does it idle OK?
Can't hurt to check the codes.

First, thanks so much for collating the info in the OP - marvellous stuff.
Just to be clear (and please forgive my ignorance), to get a fault code for ABSII, I need to ground pin#2 of the diagnostic plug, turn on the ignition and count the flashes on the temp light below the tacho? Or am I missing something?

Rob,
Go back to page one and read it carefully. You need the test LED to read-out the ABS faoults. The temp lamp only displays Motronic faults on K-bikes.

Thanks Mick. Late reply but I was just referring someone else to this thread and remembered. I did read it carefully. It is a bit (tiny bit) hard to follow as you aren't sure whether you are reading ABSI or ABSII instructions but the best thing is to just try it. It works! That's the main thing. I have rarely felt such joy as waiting those 30 seconds of re-set. Firing up and seeing (and hearing) everything work just fine. Who'd have thought ABSII hydro relays would unstick themselves?
