P0606

CIRCUIT DESCRIPTION

This diagnostic indicates that the PCM detects an internal microprocessor integrity fault.


CONDITIONS FOR SETTING THE DTC

The PCM detects an internal microprocessor integrity fault.


ACTION TAKEN WHEN THE DTC SETS

^ The PCM illuminates the Malfunction Indicator Lamp (MIL) when the diagnostic runs and fails.

^ The PCM records the operating conditions at the time the diagnostic fails. The PCM stores this information in the Freeze Frame and/or the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC

^ The PCM turns the MIL OFF after three consecutive drive trips that the diagnostic runs and does not fail.

^ A last test failed (current DTC) clears when the diagnostic runs and does not fail.

^ A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.

^ The PCM battery voltage is interrupted.

^ Use a scan tool in order to clear the MIL/DTC.
