2.4 OBD II DEFINITIONS
Power Control Module (PCM) - OBD II terminology for the on-board
computer that controls the engine and the drive.
Malfunction Indicator Lamp (MIL)- An inscription or pictogram
on the dashboard. This indicator alerts the driver that a malfunction
has occurred in the system that causes the exhaust emission limits
to be exceeded. If the MIL indicator is lit continuously, there is a
problem with the vehicle that requires the car to be brought to service.
There may be a case or type of vehicle where the MI is flashing The
flashing indicates a serious fault and informs the driver not to operate
the vehicle. The MIL display will not be deactivated by the vehicle
diagnostic system until the cause of the fault has been corrected by
repair.
DTC - Diagnostic Trouble Codes (DTCs) identify which part of the
emission control system is malfunctioning.
Snapshots - Recorded Data - When an emission-related error occurs,
the OBD II not only records a DTC, but also takes a snapshot of the
vehicle's operating parameters to identify the problem. This value
parameter, along with operating parameters, helps to identify the
problem. This set of values is called a frozen data set and may contain
important data about the engine, engine speed, airflow, fuel pressure,
coolant temperature and other important parameters
