5.1 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”, which are
fault codes, or trouble codes that have been stored in the
vehicle computer memory because the faults have reoccurred
for more than a specified amount of key-cycles. These codes
will cause the control module to illuminate the malfunction
indicator light (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 Co
des will not turn on the malfunction indicator
light (MIL). If the fault does not occur within a certain
number of warm-up cycles, the code clears from memory.
