Conditions for Clearing MIL/DTC

PCM 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 P1650 will clear after 40 consecutive warm-up cycles have occurred without a fault.
DTC P1650 can be cleared by using the TECH 2 CLEAR INFO function or by disconnecting the PCM battery feed.
