BMW Service - Clearing a fault from BMW ABS I & ABS II systems

How to clear a fault from your BMW motorcycle with ABS I or ABS II. Affordable Beemer Services LLC Manchester, New Hampshire USA

Also one more tip for ABS1 and ABS2 - You can put an oscilloscope or a LED+resistor(8k+) (EDIT: I use a ~50k resistor - a dim LED, but it works) setup (Don't use a lower resistance, or 12V bulbs - too much current) across that middle pin and battery ground to read the fault codes - the 'code' is basically the number of blinks you get between long pauses.

For example, my K bike blinked 5 times, stopped blinking for ~6 seconds, blinked 5 times and so on. 5 blinks is code for low battery - I charged it up, cleared the code and my ABS works since.

You can google the codes, but for completion's sake I'll just copy some here:

1 No response from Front pressure modulator
2 No response from Rear pressure modulator
3 Open circuit between the brain and Front speed sensor
4 Open circuit between the brain and Rear speed sensor
5 Low battery voltage
6 Defective ABS relay (weak battery can cause this error)
7 Internal brain defective (weak battery can cause this error)
8 Front and/or Rear Speed sensor gap incorrect
9 ? Is reported to happen, but it's unknown
16 Failed plunger test, persistent

This video saves you a lot of money, because resetting at BMW cost a lot. Thank you Chris for this. Interesting that there is not much on the www to this. Greetings from Munich

Thank you for posting this helpful as mate ..93 K1 owner ..no abs issue anymore

[ChrisR.Harris]

Someone apparently did not know what it was and cut it off! No need to 'hook it back up' as it is a dead end connector. Just use the brown wire to ground for 10 seconds and clear the fault. Good luck, Chris

[edwardjones]

Great INFO!! Thanks Chris. I love how you use tools found around most nice home shops. I sure BMW sells a "special" tool to ground the center pin for $100. :)

When I bought my used K1100 LTA, I had to constantly clear an ABS fault, until I got around to replacing the aged rubber brake lines with new stainless steel lines. It was the rear line that was at fault.

[musikvgen]

many thanks from Patras, Greece!
thanks!

Worked a treat! Payed €50 last time, took me 5 minutes now :D

Hey Chris. Great videos. Been studying them. Wondering about clearing ABS fault codes on a 2004 R1100s with the IABS "whizzy" system. My code reader is the round version with 5 wires. Thanks for all the help. Glenn

[menfromglen]

Just wanted to say thanks for this video! You saved me probably a couple hundred from the dealership.

[jczeduke]

Try this today, it totally worked ! Thanks for this trick !

I just did this on an R1100R year 2, 000. It worked perfectly to clear the fault.
I wonder what caused the fault and if I'll have to send the ABS module to have it rebuilt soon.
Hey Chris, Thanks for the video.

[himashmountain]

Still a good video! RE-set my Beemer today after swapping the faultje sensor for a new one.

I just cleared my ABS fault on R1100R OK. When get up to speed the ABS makes the clunk noise. Unfortunately right after the clunk noise, I get the ABS fault again. I'm planning on send to ABS unit to Module Master. They charge $350 to rebuild it. While I got the ABS unit removed, I will also replace the alternator. The R1100R has a 50 Amp BOSCH. I will upgrade to the 60 Amp that came with the R1150R with BOSCH generic.

Would love to see an ABS modulator removal for BMW K75! thanks in advanced!

Dear Chris, about 9 years from now you will make a video from somewhere up north, Maine?
At that time I will see a vid you made 10 months ago near Christmas.
I am hoping your life can move forward, your knowledge and skills with cycles will not go to waste.
I would imagine if you wanted to work on cycles you could just say so and people would ride to you for your expertise, without a shiny shop.
Put your hands back to work please.
Forgive me for saying this.
Please
