Conditions For Cleaning MIL/DTC

PCM will switch the MIL OFF on the third consecutive trip cycle in which the diagnostic has been run and the fault condition is no longer present.
A history DTC P0300 will clear after 40 consecutive warm-up cycles occur without a fault.
DTC P0300 can be cleared by using the TECH 2 CLEAR INFO function or by disconnecting the PCM battery feed.
