+For instance, in a modern car there will be no mechanical linkage from the pedal to the engine, instead the throttle pedal will be linked to a sensor to determine how
+far the pedal is pressed. 
+This sensor will be read by a micro-controller, and passed, via CANbus, to the Engine Control Unit (ECU)
 which will use that information (along with information from other sensors) to adjust the power required from the engine.
+This adjustment could be direct, or could  be another CANbus message passed to a micro-controller regulating engine function.
 In terms of FMEA, see figure~\ref{fig:distcon}, our reasoning path spans four interface layers of electronics to software.
 Traditional FMEA does not cater for the software hardware interface, and here we have the addition complications
