A controller area network (CAN) controller and transceiver device implementing an output CAN network as a mirror of an adjacent connected input CAN network, the output CAN network and the input can network both comprising at least first data wires. The system includes a first diode device interposing the input and output CAN networks such that a signal on the first data wire of the input CAN network can propagate to the first data wire of the output CAN network but not vice versa.

Security data diode

A system and method to preserve the integrity of data being extracted from an electronic data recorder ('EDR') of an electronic control module ('ECM') makes use of a forensic link adapter () and, optionally, a sensor simulator () (when the ECM is out of the vehicle). The forensic link adapter () has one or more first microprocessors () and associated first software which prevent any message being sent by an external network from corrupting the previously recorded data measurements. The data measurements are then extracted, verified, and stored in a separate file. The sensor simulator () has one or more second microprocessors (), associated second software, and a bank of resistors () that mimic sensors normally in communication with the ECM. The simulator 'tricks' the ECM into thinking it is still in the vehicle by using the replicating vehicle system values the ECM normally sees when in the vehicle.
