Retrieve/Clear Continuous DTCs is a functional test of PCM. DTCs can be retrieved or cleared with ignition on and engine off, or engine running. Unlike KOEO and KOER self-tests, which can only be activated on demand, 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. For vehicles with California emissions, DTC P1000 may be only DTC displayed, indicating an incomplete OBD-II drive cycle (more drive time needed). For additional drive cycle information, see DRIVE CYCLE PROCEDURE under ADDITIONAL SYSTEM FUNCTIONS in appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
