should be replaced before performing any tests.

being performed, and indicate if the code being received is
a KOEO, KOER or CM code:
O = Key On Engine Off (KOEO) Test/code
R = Key On Engine Running (KOER) Test/code
C = Continuos Memory (CM) code
These icons also identify the "code type" when viewing
Diagnostic Trouble Codes that are saved in the Code
