Automotive data logger
First Claim
1. A method of logging automotive diagnostic data with a self-contained, hand-held automotive diagnostic tool comprising the steps of:
- a. connecting the automotive diagnostic tool to a programming device;
b. programming the tool to log specified diagnostic data in response to detection of a specified vehicle diagnostic indicator(s);
c. connecting the tool to a vehicle diagnostic port to receive diagnostic data therefrom;
d. detecting the occurrence of the specified vehicle diagnostic indicator(s); and
e. logging diagnostic data for a selectable pre-indicator detection period and a selectable post-indicator detection period.

Abstract
A self-contained, hand held automotive diagnostic tool and method for logging automotive diagnostic data is disclosed. An automotive diagnostic tool is connected to a programming device, at which time the tool is programmed to log specified diagnostic data in response to detection of a selected vehicle diagnostic indicator. The tool is then connected to a vehicle diagnostic port, where diagnostic information is received by the tool. The tool detects the occurrence of the specified vehicle diagnostic indicator and logs diagnostic data for a selectable pre-indicator detection period and a selectable post-indicator detection period.

21. A self-contained, hand held automotive diagnostic tool comprising:
-
a. a vehicle connector port for connecting the automotive diagnostic tool to a vehicle diagnostic port on a vehicle;
b. a detector circuit in communication with the vehicle connector port, the detector circuit being programmable to detect a specified vehicle diagnostic indicator(s) from the diagnostic data received from the vehicle connector port; and
c. a memory circuit in communication with the vehicle connector port and the detector circuit, the memory circuit being operative to temporarily store diagnostic data for a specified period of time, and to log stored diagnostic data in response to the detection of the specified vehicle diagnostic indicator(s), for a specified pre-indicator detection period and a specified post-indicator detection period. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A self-contained, hand held automotive diagnostic tool comprising:
-
a. a vehicle connector port for connecting the automotive diagnostic tool to a vehicle diagnostic port on a vehicle;
b. a memory circuit in communication with the vehicle connector port, the memory circuit being operative to store the diagnostic data received from the vehicle; and
c. a deletion circuit in communication with the memory circuit, the deletion circuit being operative to scan the data within the memory circuit for the specified vehicle diagnostic indicator and delete data not within the selectable pre-indicator detection period or the post-indicator detection period. - View Dependent Claims (35)
