Replace OEM LHS TC/ABS switch BMW S1000RR

[senator8]

I'm on my second OEM switch block on a 2010 and it's gone again. Can't justify the expense of the aftermarket alpha/stm switchs etc.

So I thought that given the constant OEM failures and high cost of prewired aftermarket solutions that it might be of interest to any race/track bike owners not requiring the other switches (blinker, headlights, horn etc) or even if you want to remove the switch for safe keeping in case of a crash at the track. Or if like happened to me at a race meeting, you're at the track and your switch fails and you want to be able to switch TC/ABS on/off and nobody has a spare.

I've stationary tested it and works fine. No warning lights or faults. I won't get a chance to double check everything and ride the bike for another month or so.

The below photos show the plug and the pins within the plug that operate the TC/ABS button.

The wires if you wish to splice into them are brown/blue & brown/black.

The end result is this complicated piece is removed and goes:

To this - single round black momentary switch allows switching of the Traction Control and ABS if you have it connected.

Hi Rick, So the two wires you joined together do traction and ABS ? Do you have your abs on the bike or is it removed ? My ABS pump has been removed, just wondering if that would trigger a fault code or something silly. Nice work man, get rid of all that crap on the left bar. Cheers

Very tidy! Nice work, Rick.

Hey Steve,
I just used the wire in the photo to show which pins. It's normally open circuit and you just need a momentary switch to close it (same as OEM)
My ABS is also removed. There are no codes coming up and as far as I can tell from the original switch block it is just a switch, albeit a complicated one.
I can't be 100% sure until I can ride it and the bike goes through the TC self test. I'd ride it up the road if I didn't live opposite a highway patrolman.
It's a good way to go to get rid of those vulnerable plastics even just to take the oem switch off for safe keeping

Rick , the bit you removed with the blue buttons looks like something that controls the tardis ..
