Self-diagnostic lets you manually activate system tests that check for DTCs.
Usually it includes a KOEO (Key-on, engine-off) test and a KOER (key-on,
engine-running) test.
To read codes from a vehicle:
1. Press Read Codes from Select Diagnostic Function menu. A code list
including code number and its description displays. The red icon
means there is help information available for the code. The green icon
means there is freeze frame available.

● Freeze Frame - select one fault code from the code list and click Freeze
Frame button at the bottom bar. The screen will display freeze frame detail
data, a snapshot of critical vehicle operating conditions automatically
recorded by the on-board computer at the time of the DTC set. It is a good
function to help determine what caused the fault.
