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 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.
Permanent Codes are DTCs that are "confirmed" and are
retained in the non-volatile memory of the computer until an
appropriate monitor for each DTC has determined that the
malfunction is no longer present and is not commanding the
MIL on. Permanent DTC shall be stored in non-volatile
memory and may not be erased by any diagnostic services or
by disconnecting the power supply for ECU
