Retrieve/CMDTCs is a functional test of the PCM. DTCs can be retrieved or cleared with the key on and the engine off or running. Unlike KOEO and KOER self-tests, which can only be activated on demand, the Continuous monitor is always active in monitoring the system. When a fault is detected, a DTC will be stored in memory to be retrieved at a later date, making it possible to diagnose intermittent faults. A P1000 DTC may be the only DTC displayed, indicating an incomplete OBD drive cycle (more drive time needed). The fuel injection control module (FICM) monitors the injector circuits for a fault continuously. The FICM sends failure information via CAN communications and a PCM DTC is set. CMDTCs indicate the injector electrical system failure.
