Abstract:
1. A universal translator for vehicle information systems comprising: a tool interface that receives requests and provides responses; a communication circuitry that selectively converts requests and responses from one or more translator protocols into a microprocessor readable format and that selectively converts microprocessor format requests and responses into the one or more translator protocols; a vehicle interface that provides requests and receives responses; a microprocessor that controls the communication circuitry to translate received tool interface requests from a tool protocol to a vehicle protocol, that provides the translated requests to the vehicle interface, that translates received vehicle interface responses from the vehicle protocol to the tool protocol, and that provides the translated responses to the tool interface; a non-volatile memory coupled to the microprocessor, wherein the non-volatile memory stores operating code for the microprocessor; and a data port coupled to the non-volatile memory, wherein the data port is operable to receive external data that alters the operating code stored within the non-volatile memory, wherein the data port is further coupled to a memory unit, wherein the microprocessor stores diagnostic requests and diagnostic responses in the memory unit and the stored diagnostic requests and the stored diagnostic responses are retrievable via the data port from the memory unit.
