1. Read Codes
- Reading Codes can be done with the key on engine off or with the key on engine running.
- Stored Codes are also known as “hard codes” or “permanent codes”.
These codes cause the control module to illuminate the malfunction indicator light (MIL)
when 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 amp (MIL) If the fault does not occur within a certain number of warm-
up cycles, the code clears from memory.
