DISCUSSION:
The On Board Diagnostic (OBDII) system includes a monitor called readiness codes. The readiness codes indicate that all OBDII diagnostic tests have
been performed and that diagnostic trouble codes (DTC's) can be read. It has been determined that the readiness codes may be cleared upon ignition key
"OFF" cycles. Absence of readiness codes may cause owners to fail their emission inspection. To correct this condition, the Powertrain Control Module
(PCM) must be reprogrammed.
