Hello all, I just got back from chatting with the local bike shop owner. Was talking about wiring and ABS systems. He recommended just removing the module and wiring instead of chancing the module actually working once I put it all back together. Is it as simple as removing the Abs unit wiring from the module back to the harness? Thanks for any help.

Year and model?

It "doesn't matter" if the ABS doesn't work. With a faulted ABS system you just have normal, non-ABS braking.

No, that's Waterloo, Iowa. Very Happy

1985 does not have ABS. 1988 was the first year for ABS.

Damn, you're right! it's the CONTROL UNIT L-JETRONIC throttle control. I guess I shouldn't remove that! Have to continue with plan on putting it somewhere under the seat. Shoot.
Thanks duck!

Under Profile on the Forum's main page, choose Signature, then add the year and model of your motorpickle, then save it, so no one has to request the info from you when you're asking a question. We assume you have a BMW K bike but would have to look back at your Member's Intro post to see if it's there...


You can also add your favourite silly quote if you like.

Of course if you manage to contract K Pox you end up with a signature like mine.....

For those who actually want to remove ABS from their K100 (ABS 1), it's pretty easy, but no wiring has to be removed (except the sensors and switch wiring). The ABS control unit sits in the tail glovebox, and the wiring is part of the main loom. You can cut it...but expect issues.
You can remove:
- the control unit
- the two pressure modulators
- the pipes and rubber tubes
- the sensors and their bracket
- the switch
- the relay
- and, for the weight intolerants...remove the ABS bulb in the instruments cluster (don't forget to erase the ABS mark!)

and change the rear disc and one front disc for non-ABS discs, without the sensor crown. You can simply remove the front crown, but the ABS disc bowl is different and heavier.
By removing all this, you will save more than 14kg!

So when I looked up the mystery module that was in a cardboard box I thought it was this:
Remove ABS module and wiring? Img_0313

But apparently it’s this:

Remove ABS module and wiring? Img_0314
The modules look similar and there is a sensor that goes into the rear drive that I can’t find on the fiche. Another mystery…

Hi again, here with another question. This switch/sensor plugs into my rear differential (no jokes please) and in the fiche it says it's a Stop Light Switch. What the !$%@# is it and what does it do? Many thanks.

That's the LE Jetronic fuel injection control unit in the upper right corner of the second diagram. The attached diagram answers your last query. I use MaxBMW's parts fiche; it just seems less cumbersome.

The rear wheel speed sensor is the bit that goes into the final drive, and it's shown with the horn in the electrical section (group 62) of BMW parts catalogues like realoem.com, or other. It's known as a 'pulse generator'. The L-Jetronic control unit is the metal 'box' the size of a good book that sits on top of the battery/coolant overflow tank, beneath the seat. That and the small, grey module for the ignition, mounted to the forward part of the main frame, are the only two control units on your model K bike.

You can search BMW part numbers using realoem.com, or other (some like Max BMW's site). BMW part numbers are always 11 numbers (no letters), but you need only the last 7 numbers to search in the catalogue for fitment. The part numbers are often conveniently on a sticker or stamped into the part in your hand while you're sorting out what it is. They supersede a lot but there's often a part number trail you can follow. Drill down into the info as far as you can go for the actual model as BMW overlaps within catalogues between standard, RS & RT, LT, & etc.

Your bike does not have a rear differential, as the drive shaft is motivated by only one side, not out both sides like an automobile's 'differential'. It's simply a final drive. Look at the other post you made for the answer to where your rear wheel speed sensor is shown in the catalogues. Both Laitch and myself posted the required info simultaneously to you. Prolly not necessary to create an entirely new thread for the one question asked twice. I might will join these two threads up to streamline it.

I asked the question in the new thread under Engine and Transmission. Not sure how it got copied into the ‘ABS’ thread. Speed sensor eh? Wish they’d pick a wheel, the speed sensor is on the front wheel of my K1300R. As for the differential, the parts fiche calls it the differential housing.Shocked

The sensor for the speedometre is in the final drive on your K1300R. The sensor you see on left hand side of the Duolever suspension of the K13 is simply the front ABS sensor. The rear sensor in the final drive does speedo, traction control and ABS functions. BMW have used different location over the years on various models. When cables were king the Oilheads used one off the left side of the front wheel. Airheads get their signal through a cable out of the top of the gearbox, & etc.

Your earlier question/comment..."and there is a sensor that goes into the rear drive that I can’t find on the fiche. Another mystery…"is the reason I merged the topics.

I've seen it written as 'Denglish.'

Sho'nuf:
"This mixture of German awash with English expressions and German-English mish-mash is known as "Denglish" and appears to be increasing in popularity - especially with younger people."

I'm not a younger people and glad of it. Smile  Younger people also use like instead of said, replied, answered, and responded. I'm not about to hitch up to that notion, either; besides, Spanglish is my native tongue.

After further reflection, and an epiphany borne by a dream involving a flock of Roseate Spoonbills and a kayak paddle, I would consider Deuglish as suitable. cheers
