An engine control system includes a status determination module that determines states of first and second throttle position sensors, wherein a fault state includes when one of the first and second TPSs is one of outside of a predetermined range and out of correlation with the other of the first and second TPSs, for greater than a first predetermined period. The magnification of the variable magnification optical system is changed by changing a distance between the first lens group and the second lens group in the direction of an optical axis. The user interface provides common graphic forms for both inputting the data to the simulator as well as for displaying the resultant data from the simulator. Upon a failure to decode the codeword using the partial subsets, the codeword is re-decoded using the data bits and all parity bits in the input, and using all equations. Once enabled, the loss prevention may be disabled by a predefined message received from the server.
