1994 850 a/t Code 122 & 211

[Samus850]

Hello all, I am a new member here and new owner of a 94 850 wagon, it's a non-turbo with automatic.
I have owned the car 1 week and have already logged 400 miles.
Today while letting the car idle and trying to recharge my a/c system, I hopped in the car and noticed the flashing arrow. I limped the car home 10 miles and checked for faults when I got there.
There are actually 11 separate codes stored! I reset them but A1 and B2 both have 122 and will not reset, in fact, A1 glows dimly as soon as it is plugged in.
I have read about the PNP switch and tomorrow will attempt to remove, inspect and clean it while checking all connections and wires.
Also, since resetting the codes, the ABS light is on and cannot be reset. I have been scanning the forum and will post as soon as progress is made, but in the meantime would greatly appreciate any advise!

Thanks,
Michael
