As you don’t have codes it’s probably not the 190 change. In your case the only thing I would try is to remove the blue wire from the B9 pin and wire it per old instructions taking power from the wire harness and not the JB4 controller. I would however see what BM recommends as the unit you both have is a newer gen that my unit.
