Lets start by checking fuse #35 in the passenger fuse box.
If you need further assistance, just let me know.
Has it worked before?,,,are you the original owner?
Here is some info on the system for you.
Thank you very much,
Most likely the problem is in the ABS ECU ,,,,,basically the computer for the brake system.
Unfortunatly its going to require a factory level scanner to hook to the computer and monitor the function when tryong to apply the switch,,,,,sorry, i sure do wish i could give you the silver bullet to correct this, but its impossible without that scan tool. Dont worry about the accept if you dont want to,,,i just cant go any further :-(
Best of luck my friend!
