I wired a ON/OFF rocker switch into the rear brake ABS sensor circuit. When switched off this basically causes the ABS to fault and turn off.

Now when off road I flip the switch to the OFF position the ABS stays off until I want it on again. No need to touch the factory ABS switch.

All it cost me was:

1) On/Off rocker switch
2) 2 male / 4 female wire connectors
3) about 8 feet/2.5 meters 16 ga. wire
4) 1 hour of my time

I had all this stuff lying around so it was free for me, might cost $10-$15 if you had to buy it.

The first step is to follow the glossy black wire from the rear ABS sensor pickup, you will find it ends under the seat above the rear shock.

I stripped about 40-50mm of the insulating cover off the wire leading into the female side of the connector. I cut one (doesn't matter which one ) of the wires and added wire connectors and then ran two wires along the frame rails to my switch on the dash.

When the switch is flipped OFF the signal from the rear ABS sensor is interrupted causing the system to detect a fault and turn off.

Here is a picture of the factory connector under the seat and my "splice" into it. The black stuff you see on my connectors is "liquid tape" for some additional water proofing. ( sorry, the pic could be be better, but you get the idea )



Here is a pic of the dash switch. I got this switch from Radio Shack for $3.

To turn the ABS back on just flip the switch back to ON and restart the bike.

You could also tap into the front ABS sensor and accomplish the same thing ( speedo/odo won't work though ).

Brilliant! I'll be into this on the weekend, including the handlebar switch.

So I have a question for rgmax or anyone else that's done this:

When the rocker switch is "off" does the factory ABS light still blink as an error? It'd be nice if it does, I'd like having it there reminding me to flip the switch "on" when I get back to pavement.

Strange thing happened this sunday. I started the bike and b4 the ABS light went out, I pressed it to deactivate it. This did not work, and I could no longer deactivate it. However, I did not turn the bike off and restart to see if it was really screwed up.

Request for a little update (still haven't started to put the switch on my bike ): Do you know if it generates errors that the dealer can see if he hooks the bike up to the computer?

By "red handlebar switch" do you mean the main switch on the right hand switch unit?
So do you replace OEM wiring into this red handlebar switch?

Sorry English is not my native language.

No, he actually added a new pushswitch to the left hand side unit, pics are not showing anymore for some reason (on my pc )...

So in theory he fakes a shortcircuit in the sensor which disables the ABS on the fly.
Should not hurt anything but I wonder if the CDI logs errors about this...

Is it Triwi avoids cuting the OEM wires? Seems the same to me. Or is it yours doesn't produce error signals? Pls enlighten me. Cheers.

P.S. Pictures are not attached any more because we need to host them on a pay host somehow. My "masterpiece" study on slave cylinder failure is crippled. Oh! what the hell?

I don't have a solution yet... But I think I will try Triwi's this winter.

But this is Triwi's:

Whenever the ignition is switched on the ABS automatically resets. No need for a rocker type switch which has to be manually switched which is needed if you loop just one side of the circuit to the bar switch.
Have to say I did querie the sparky about apparently introducing a short circuit by doing it this way but he just smiled and said No. Before doing the 990 I alterred my 650 Dakar and have been running it for a month. Works perfectly. No ill effects whatsoever plus the bonus of automatic reset every startup.
cheers

Maybe if he sees these questions, he will post the pics again

The only difference between Triwi's version and rgmax's version is the switch. Both require cutting into the rear ABS sensor wires. Triwi's version uses a temporary interrupt button which disables the ABS as long as the bike remains on. Same as the stock button, but no 3 second holding period, and also works while the bike is moving. If you turn the bike off and turn it back on the ABS will be active again. rgmax's version uses a permanent interrupt switch which disables the ABS as long as the switch is flipped. If you turn the bike off and turn it back on the ABS will still be deactivated unless you flip the switch back before you turn the bike back on.

I prefer the permanent switch because I don't want to have to remember to turn the ABS off everytime I restart the bike offroad. ABS on dirt is SCARY. This comes with the downside of forgetting to enable the ABS on the road. Much less of an issue. I've ridden plenty of other bikes on the street without ABS.

It really comes down to personal preference. Do which ever works best for you.

What I did while riding off road for the weekend was just put a couple washers between the sensor and the housing onthe rear wheel. Moving the sensor away from the ring by just that small amount made the signal unreadable and the ABS was off.

To under just remove the screw and put the washers on the other side outside of the sensor and your done.

No cutting into the wiring harness and takes only couple secs to do.

The really cheap penny trick.

Then it's off permanently, and so, can not be activated again easily/fast when riding home on the road... But I like the idea for a 2 week offroad trip though

Like I said the REALLY CHEAP (Like KLR Cheap) penny tech.
