Good Day, so attempted to do rear brakes on the 18 EC, so did the 2 wire and 12v trick to retract one of the caliper. Went in all the way then while trying to switch the pads I realized I had the wrong pads.
So I put everything back in
Go in the cat and now parking brake service required. The side where I retracted the calliper looks like isn't working when I push and release the ebrake
Is there a fuse or something? Or a reset method?

You have likely damaged the system. Refer to a dealer that knows the system, and has qualified mechanics to fix your mistake
