So I am guessing I must replace re abs module. Anybody else have this code an it be something else? Just curious of those with same problem.

This comes on randomly and is not all the time. For some reason everytime it rains or high moisture I get the code.

Last time you changed brake fluid and put the ABS into action to clean it out?

If not done do it now for the cost of brake fluid, water down your road at home and slam the brakes on a few times to activate the ABS. Follow the manual when changing brake fluid by doing each wheel in the right order, and verify the ABS.

It may save you replacing the module.

I have done two flushes. Just by usin the bleeders in the correct sequence. Buy never actuated the abs during. Is there a way to do so. Or you just saying. Engage abs a few time to kinda get the new fluid in there?

Yes, engaging the ABS intentionally will dilute the fluid in there with new fluid. Just find an empty parking lot, get up to 20 mph or so, and stand on the brakes a few times.

The ABS needs to be activated and while this takes place your foot is on the peddle and force withing the brake lines pushes against the wheel cylinder, the calipers and the ABS valves that may or may not have a build up of fine particulate that may release into the brake fluid and travel along and eventually be removed as you do your 2-3 year bleed.

To give you an idea of how dirty it can get take the screen out of the M/C and look in the bottom. That dirt should be sucked out before a bleed or it will be sent down and through the system and ABS where you may get a valve lock up or partial lock up.
