Stored codes are the current emission related DTCs from the ECM of
the vehicle. OBD II/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.
Erase Codes
This option is used to clear all emission related diagnostic data
such as, DTCs, freeze frame data and manufacturer specific
enhanced data from the vehicle’s ECM.
A confirmation screen displays when the clear codes option is
selected to prevent accidental loss of data. Select Yes on the
confirmation screen to continue or No to exit.
