5.2 Reading Codes
• Reading Codes can be done with the key on engine off (KOEO) or with
the key on engine running (KOER).
• 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 an emission-related fault occurs.
• 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.
