1. A vehicle data recorder, comprising:
- a first connector that communicates with the vehicle'"'"'s computer and relays data to and from a vehicle;
a processor that controls the vehicle data recorder functions;
a memory in communication with the processor to store recorded data;
at least one communication protocol controller, wherein the at least one communication protocol controller includes a CAN controller for CAN protocol communication with the vehicle'"'"'s computer; and
a second connector that communicates with a host workstation to transfer the recorded data from the vehicle data recorder to the host workstation.

Abstract
An apparatus and method is provided that allows a user to record events in a vehicle via a vehicle data recorder in the latest communication protocols, such as Controller Area Network. The vehicle data recorder can record data from the event when a trigger button is actuated by the user and the CAN communication can be controlled by the CAN controller. After the data is recorded, it can transferred to a host workstation, where the user can analyze the data from the event and diagnose the problem causing the event.
