Stored Codes is also known as Hard Codes or Permanent Codes which cause the
control module to illuminate the Malfunction Indicator Lamp (MIL) when mission-related
fault occurs.
Pending Codes is referred to 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 will be cleared from memory.
Note: Reading Codes can be done with the key on engine off (KOEO) or with the key
on engine running (KOER).
