Conditions for Clearing The MIL/DTC

The ECM will turn the MIL "OFF" on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
A history DTC P0601 will clear after 40 consecutive warm-up cycles have occurred without a fault.
DTC P0601 can be cleared by using the Tech 2 "Clear Info" function or by disconnecting the ECM battery feed.
