Abstract
A compressed air operable wheeled trailer braking system includes a braking electronic control unit (ECU) having an electronically operable control valve which derives suitably proportioned load and vehicle speed dependent service brake pressure for brake chambers of the trailer wheeled. The braking ECU has a data memory storing specific braking parameters normally installed therein prior to commissioning the trailer. The trailer has a further diagnostic ECU responsive to vehicle operational sensors, the further ECU also having memory capacity. The specific braking parameters are stored via a communication link consequent upon installation thereof to the braking ECU. Upon recognizing installation of a replacement braking control unit, the parameters from the further ECU are installed in the replacement ECU.
