By failing to monitor the catalytic converter, the evaporative system for leaks, and
the presence of engine misfire, OBD-I did not do enough to lower automotive
emissions. In addition, the ... functions. OBD-II diagnostic tests Depending on the
OBD-II system, the Diagnostic Executive (usually referred to as the Executive)
performs tests on up to seven emission systems Malfunction Indicator Lamp (MIL
): A type of OBD test result that lights to alert the driver of a faulty automotive
circuit.

SAE J1979/ISO 15031-5 specified a set of nine standard messages (diagnostic
test modes, also known as diagnostic services) that can be used by scan tools to
obtain OBD-II data from a vehicle. (Modes $01 to $09). Diagnostic tests modes (
or services) are simply sequential numbers assigned to various generic scan tool
functions ... Service technicians can use the data to troubleshoot control systems,
sensors and actuators, check OBD-II monitor completion status, MIL status, etc.

Some of the required OBD-II diagnostic tests appear to be very difficult to
implement with a high degree of reliability. Though processes for robust design
and complete validation of all the production versions of the diagnostics will be
employed, there are concerns that false indications will occur once the system is
in the field. These will ... Extra Oxygen Sensors: The OBD-II Catalyst Efficiency
Monitor requirements imply an additional oxygen sensor at the outlet of the
