Can a PCM monitor be set as ready?
Once a monitor is set as Ready or Complete it will remain in this state unless diagnostic trouble codes (DTCs) are cleared by a scan tool or if the PCM’s short term memory is erased by a power failure (i.e., disconnecting the battery). Since the three continuous monitors are constantly evaluating, they will be reported as Ready all of the time.
How many monitors do you need for readiness monitoring?
