ABS I Question

[MCRyder]

I've been contacting other BMW forums about this problem I'm having with my '93 K11RS w/32K miles. My ABS lights began flashing on a recent trip, just as I was exiting an interstate at 65 mph. I stopped, shut off the ignition and restarted the bike. The lights still flashed. I've done the DIY diagnostic and got a Fault Code #1, front pressure modulator. I checked the blue plugs under the tank, no problems. The battery is fully charged. I cleaned the ABS C/U plug and reseated it. Checked the grounds on the modulators, they're OK. Tried the clear the fault with the DIY method, didn't work. I've downloaded all the info that Brian Curry has on the IBMWR and the info found on the K11 Owners Group site and used the procedures detailed. I've tested the system with an Ohm meter, it showed an open which means bad modulator. But I also tested the rear modulator and got the same exact readings. I contacted Paul Glaves and Mick on the K11OG page about that and they both say that is unusual for both modulators to go out at the same time.

Has anyone else had this situation come up on their ABS I and found the solution was something other than replacing the modulators ($$$)? Appreciate any feedback.

I've been through hell with my '92 K75RT ABS system & you're doing the right thing following the lead of Brian, Mick & Don. Something that might give you an indication if it's really the modulator is to swap the input plugs front/back and see if you get a fault code for "rear modulator". The modulators themselves are identical, I believe, so this might work to give you confidence to go shopping for a replacement. I got mine from Mike F. at Beemer Boneyard and found him to be really good--he sent a second one immediately when the first turned out to have a problem.

Others chime in if this isn't a good idea.....
