I'm looking for some help understanding how to get fault code for abs1 system on a 92 K75S vin# xxxxxxxxxxx153350.

 For some back round this is a new to me bike I got late in the season last year and just could not stop myself from putting a few hundred miles on it before giving it a good going over. It is a low mileage (28,000 miles) well cared for machine. So far I have de-oxed all connectors including grounds, rad flush, all fluids (except brakes), and cleaned and lubed trans input and driveshaft splines. Because the bike is in such nice condition I would like to get the abs working and keep it in original configuration (I'm not sure how valuable abs1 is it terms of safety vs 20+ lbs of mechanicals). The battery holds 12.6 volt static charge and drops < 2 volts when cranking. 

When I turn on the ignition the abs and warning lights both flash and I can hear the relay (abs?) clicking. With an anti-log volt meter - to ground and + to center pin of abs test plug voltage goes from 12 to 2 continuously. When I hit the abs switch the lights will come on steady and the voltage on test plug will go up to 12  for 3 or 4 seconds then drop to 3,4,3,4,3,4,3,4,3,4,3 then back to 12 and the sequence will go on and on. From reading the troubleshooting guides I was expecting to see "dips" from 12 volts.

So, should I interpret this reading of 6 (small) "dips" to a faulty relay?

You would get a better/easier reading if you use a analouge meter.
And yes, you should count the dips.....so it could be code 6.

Search Tosi Tabuki...he is the ABS I guru, a lot of info on his site.
He have helped a whole lot of owners.

This is Tosi Tabuki's site and what he doesn't know about the ABS isn't worth knowing  http://bmwk10075abs1fix.web.fc2.com/

Thanks guys let me look into the stuff you gave me and and will post what I come up with.

Inge K.,
I stated that I used an anti-log meter when in fact I used an analouge meter. I feel like a clod being born and raised in the US and struggle with written English Smile

Sorry guys but this one is going to end in an anticlimactic manor.

On Tosi Tabuki's site (thanks Rick) "If your error is 6 and cannot reset it, Do Deoxit on both pump connector located under the petrol tank.It is blue color connector under both side of the tank."


Since I had already did that , I went ahead and cleared (reset) ECU and it worked!
