ABSTRACT:
An automotive powertrain assembly testing system comprising an interface module adapted to interconnect between an electronic control module of an automotive vehicle and an on-site computer system capable of accessing a remote database and data interpretation system. The interface module includes a four channel signal input capable of sampling data at a rate of 500,000 samples per second, in the range of zero to 250 volts. The interface module further includes a sample buffer capable of storing 32,768 samples per input channel. Electronic samples received by the interface module are transferred via an electronic connection to the on-site computer system, for real-time display to a system operator, and for transfer via a standard phone line or high-speed data connection to a remote database and data interpretation system. The data interpretation system receives the sampled data, compares it with acceptable data values for the vehicle undergoing diagnosis, and generates a component evaluation report. The component evaluation report is transmitted back to the on-site computer system for display to the operator or technicians, and includes a listing of vehicle components generating signals which are outside acceptable ranges. The data interpretation system further indicates to the operator or technician a repair priority for the failed components to facilitate rapid repair of the automotive vehicle.
