Data Recorder for Automotive Diagnosis 910040

A data recording system which is useful for malfunction diagnosis of ECUs (Electronic Control Units), such as those for engine control, has been developed.
It has thirty-four input channels (21-digital, 8-analog, 2-event, 3-interval) and features independent direct recording of ECU output signals and sensor signals. Since this recorder is designed to memorize these signals in two time domains as before and after a malfunction occurs, the source(s) of failure can be shot easily by analyzing the recorded data. The input data can be recorded over long periods of time, because this system uses memory card(s). A system with these functions will prove an invaluable aid for failure shooting of ever more complicated electronic units in the future.
