ABSTRACT:
In data transmission between the unlike signal-processing devices in a motor vehicle, distortion of transmitted data may occur because of sources of disturbance internal and external to the vehicle due to super position of high frequency disturbances in transmitted data as well as due to short circuits or disconnections occurring in the system. To detect such conditions the level of transmitted data messages is compared with predetermined reference-level limits which may lie within and/or without the useful signal level range, e.g., "0" to "1". Detection of error conditions as well as determination of their cause is possible by use of the method.
