Warm-Up Cycle
The
PCM uses warm-up cycles to run some diagnostics, and to clear any Diagnostic Trouble Codes
(DTCs). A warm-up cycle occurs when the engine coolant temperature raises
22°C (40°F) from start-up. The engine coolant must also achieve a minimum temperature of
71°C (160°F). The PCM counts the number of warm-up cycles in order to clear the Malfunction Indicator Lamp
(MIL). The PCM will clear the DTCs when 40 consecutive warm-up cycles occur without a malfunction.
