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” or

"permanent codes", These codes will cause

the control module to illuminate the (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 MIL. If the fault does not occur within a certain

number of warm-up cycles, the DTC clears from memory.

• Permanent Codes are DTCs that are "confirmed" and

are retained in the non-volatile memory of the vehicle's

on-board computer until the appropriate monitor for

each DTC has determined that the malfunction is no

longer present and is not commanding the MIL on.
