The problem is if you are not paying attention when replacing calipers or brake lines and you let the brake fluid gravity bleed out you get air in the ABS module. The only way to purge the air is to get to a dealer and have them hook up a Tech2 and cycle the ABS module until the air is out. The other is to drive the vehicle and lock the brakes so the ABS activates(on snow or dirt). This worked in my case, but you have to do it several times to fully purge the system of air. Involves braking then pulling your wheels bleeding then repeating.
Enough people have had this problem, from what I have read on various forums, that it would be nice to have a way to activate the ABS at home.
A good Tech2 device cost $1000 or more although there Chinese knockoffs around for under $500 but with poor reviews.
Anyways I thought I would throw this question out on this forum since there are some pretty sharp people here who might have some ideas.
Thanks for the reply
