Abstract: A vehicle diagnostic device comprises a first mode of operation in which a user can perform vehicle diagnostics on an actual vehicle that is physically connected to the vehicle diagnostic device. The vehicle diagnostic device also comprises a second mode of operation in which a user can demonstrate vehicle diagnostics on a virtual vehicle without an actual vehicle having to be physically connected to the vehicle diagnostic device.

Abstract: Electronic control apparatus for a vehicle, in particular a heavy goods vehicle, which apparatus includes an electronic control unit (ECU) adapted to control actuation of vehicle brakes. The ECU has a non volatile storage memory for storing braking related control parameters particular to the vehicle and a discretely programmable storage device to carry operating data for one or more auxiliary functions of the vehicle. The ECU is operable to check one or more incoming and outgoing variables and control algorithms against a predefined list such as to safeguard the braking function against error modes.
