1.8 Reading Codes
(1) Reading Codes can be done with the key on engine off (KOEO) or with the key on engine running
(KOER)
(2)Stored Codes are also known as "hard codes'' or "permanent codes". These codes cause the
control module to illuminate the malfunction indicator lamp (MIL) when emission-related fault
occurs.
(3)Pending Codes are also referred to as ''maturing codes'' or ''continuous monitor codes''. They
indicate problems that the control module has detected during the current or last driving cycle but
are not considered serious yet. Pending Codes will not turn on the malfunction indicator lamp (MIL).
If the fault does not occur within a certain number of warm-up cycles, the code clears from memory.
