0 - MIL is not triggered with this fault
1 - MIL is on and Freeze Frame is stored in memory
2 - MIL is on and a previous Freeze Frame is overridden
3 - MIL is blinking and a previous Freeze Frame is overridden

NOTE: In order to ensure that a fault is no longer present after a repair or after the fault memory has been erased, the vehicle road test should be ended only when a trip has been reached. This is the only way of ensuring that all diagnosis routines are carried out by the ECM.
