SELF-DIAGNOSIS FUNCTION
When an abnormality is detected in one
of the sensors or actuators related to
emission control, the engine warning lamp
(check engine lamp) illuminates as a
warning to the driver.
When an abnormality is detected in one
of the sensors or actuators, a diagnosis
OTHER CONTROL FUNCTIONS
1. Fuel Pump Control

The RAM data inside the engine-ECU that
is related to the sensors and actuators can
be read by means of the MUT-II. In addition,
the actuators can be force-driven under
certain circumstances.
