Abstract
A diagnostic tool configured to retrieve mode 6 cylinder misfire data from an engine controller using physical addressing of the engine controller. The mode 6 data is retrieved on a continuous and dynamic basis instead of a snapshot. The retrieved mode 6 data may be displayed on a GUI and may also contain other mode 6 data such as throttle position sensor, engine RPM and mass air flow.
Claims20
A vehicle diagnostic tool, comprising:
- a diagnostic processor configured to execute non-transitory computing instructions;
- a connector interface configured to connect with a connector in a vehicle and retrieve vehicle diagnostic data from the vehicle with the processor, wherein the vehicle diagnostic data is mode 6 cylinder misfire data;
- a display in communication with the processor configured to display vehicle diagnostic data;
- a wireless communication interface in communication with the processor and configured to communicate with a remote device having a vehicle diagnostic database;
- and
- a memory in communication with the processor, the memory containing the non-transitory computing instructions, that when executed by the processor causes the processor to:
- retrieve the vehicle diagnostic data including diagnostic trouble codes (DTCs) and the mode 6 cylinder misfire data, the mode 6 cylinder misfire data is retrieved continuously and dynamically by using physical addressing of an engine controller in the vehicle;
- generate, on the display, a plurality of selectable icons corresponding to individual cylinder misfire data for each supported cylinder of the vehicle;
- indicate on the selectable icons an index number of a cylinder that is misfiring, if any, for each supported cylinder;
- and
- activate a web browser on the remote device to start a repair process.

A non-transitory machine-readable storage medium comprising machine-readable instructions for causing a processor of a diagnostic tool to execute the method of:
- retrieving vehicle diagnostic data including diagnostic trouble codes (DTCs) and mode 6 cylinder misfire data, the mode 6 cylinder misfire data is retrieved continuously and dynamically by using physical addressing of an engine controller in the vehicle;
- generating, on a display of the diagnostic tool, a plurality of selectable icons corresponding to individual cylinder misfire data for each supported cylinder of the vehicle;
- indicating on the selectable icons an index number of a cylinder that is misfiring, if any, for each supported cylinder;
- and
- activating a web browser on a remote device to start a repair process.

A vehicle diagnostic tool, comprising:
- means for processing configured to execute non-transitory computing instructions;
- means for interfacing configured to connect with a connector in a vehicle and retrieve vehicle diagnostic data from the vehicle with the means for processing, wherein the vehicle diagnostic data is mode 6 cylinder misfire data;
- means for displaying in communication with the means for processing configured to display the vehicle diagnostic data;
- means for wireless communication in communication with the means for processing and configured to communicate with a remote device having a vehicle diagnostic database;
- and
- means for storing in communication with the means for processing, the means for storing containing the non-transitory computing instructions, that when executed by the means for processing causes the means for processing to:
- retrieve the vehicle diagnostic data including diagnostic trouble codes (DTCs) and the mode 6 cylinder misfire data, the mode 6 cylinder misfire data is retrieved continuously and dynamically by using physical addressing of an engine controller in the vehicle;
- generate, on the means for displaying, a plurality of selectable icons corresponding to individual cylinder misfire data for each supported cylinder of the vehicle;
- indicate on the selectable icons an index number of a cylinder that is misfiring, if any, for each supported cylinder;
- and
- activate a web browser on the remote device to start a repair process.
