So im here to hopefully help. I found this forum after I experienced the same issue after a brake and rotor change out at 50,000 miles. I put my emergency brake into service mode. Did the brake change out. Started my truck and the check engine, abs, trac control, parking brake were on, as well as a warning for limp mode. So i unhooked my negative terminal for 45 mins, hooked it back up and everything cleares up and pad life indicator reset itself.
SIDE NOTE: I have a 2022 Chevy trail boss LT.
