I replaced the brakes pads on a 2018 CX5. I did not realize you had to put it into maintenance Mode. Once I got resistance while collapsing the piston I searched the problem and put it in maintenance mode. I must have broke the connector on the actuator so I ordered a new one and put it on. Now I can't get it out of maintenance mode and the parking brake light is flashing. I am getting no power to the actuator. I checked the fuses and they are good. Any idea where to locate the brake controller? Is there something I am missing?
