CIRCUIT OPERATION
⦆
The injector power is supplied from the injector relay
(terminal No. 3).
⦆
The ECM controls the injector by turning the power
transistor in the ECM "ON" and "OFF".
TECHNICAL DESCRIPTION
⦆
The amount of fuel injected by the injector is
controlled by the amount of continuity time the coil
is grounded by the ECM.
DESCRIPTIONS OF MONITOR METHODS
The ECM detects open circuit and short malfunction.
