Abstract

A method and apparatus are provided that allow an off-the-shelf USB flash memory device to used with a scan tool. The USB flash memory device can have a different operating system then the proprietary operating system of the scan tool. The method and apparatus allows the scan tool to read from and write on the USB flash memory device regardless of the formatted operating system on the device.

Claims

1. A computer product for use by a vehicle diagnostic scan tool, the product comprising a non-transitory computer-readable storage medium in which program instructions are stored, which instructions, when read by the diagnostic scan tool, cause the diagnostic scan tool to perform the steps comprising:

detecting a USB flash memory device that is formatted for an operating system that is different from an operating system used by the vehicle diagnostic scan tool that is coupled to the vehicle diagnostic scan tool;

collecting diagnostic information from a vehicle that is coupled to the vehicle diagnostic scan tool; and

writing the diagnostic information on the USB flash memory device that is formatted for an operating system that is different from the operating system used by the vehicle diagnostic scan tool at a sector level,

wherein writing the diagnostic information on the USB flash memory device comprises writing on a sector by sector level; and

wherein writing the diagnostic information on the USB flash memory device further comprises writing without using a file system.

2. The computer product of claim 1 further comprising saving diagnostic information on an internal memory of the vehicle diagnostic scan tool.

3. The computer product of claim 1 further comprising displaying a counter on a display of the vehicle diagnostic scan tool.

4. The computer product of claim 1 further comprising determining if a predetermined number of frames have been captured.

5. The computer product of claim 4, wherein the number of frames is between about 1-1000.

6. The computer of product of claim 4, wherein a file is closed when the predetermined number of frames have been captured.

7. The computer product of claim 1 further comprising communicating with a driver of the USB flash memory device in order to determine if the USB flash memory device is attached to the vehicle diagnostic scan tool.

8. The computer product of claim 1, wherein writing the diagnostic information on the USB flash memory device comprises writing without using a DOS FAT 16 or FAT 32 file system.
