Function Descriptions
This section describes the various functions of each diagnostic option:
DTC & FFD
When this function is selected, the screen displays a list of Stored Codes and Pending
Codes. When the Freeze Frame data of certain DTCs are available for viewing, a
snowflake icon will display on the right side of the DTC item. The Erase Codes function
can be applied by tapping the function button at the lower bottom of the screen.

Stored Codes
Stored codes are the current emission related DTCs from the ECM of the vehicle. OBDII
/EOBD Codes have a priority according to their emission severity, with higher priority
codes overwriting lower priority codes. The priority of the code determines the
illumination of the MIL and the codes erase procedure. Manufacturers rank codes
differently, so expect to see differences between makes.
