FUEL INJECTION CONTROL
MULTIPOINT FUEL INJECTION (MPI) <4G1>13B-7
FUEL INJECTION CONTROL
M2132003000851
The following control is basically the same as those
of the 4G6-MIVEC engine used in the GRANDIS, the
following improvements have been added.•Fuel pressure control solenoid valve
In accordance with the signal received from the
engine-ECU, the fuel is controlled.

THROTTLE VALVE OPENING ANGLE CONTROL AND IDLE
SPEED CONTROL
M2132003500209
The following control is basically the same as those
of the 4G1-Non-Turbo engine used in the COLT, the
following improvements have been added.
•Clutch monitor switch
The clutch monitor switch inputs the signal into the
engine-ECU to transmit the information about
whether the clutch pedal is depressed or not. By this
signal, the engine-ECU identifies the clutch pedal is
depressed when the transmission is shifted, and per
-
form the following control. When the clutch pedal is
depressed, the throttle valve is automatically closed
and the ignition timing is retarded at the same time.

CENTRAL DOOR LOCKING
•Centre door locking system that locks and
unlocks all doors (including tailgate) via the
driver’s door key cylinder or the driver’s door
inner lock knob has been adopted.
•A child protection is used to prevent the rear
doors from being opened accidentally during driv
-
ing.
•Key-in prevention function has been introduced
for driver's door.
•"P" position shift linked door-unlock function has
been introduced.
•Direct combination key cylinder mechanism has
been adopted to maintain its function at the side
impact and improve theft protection.

KEYLESS ENTRY SYSTEM
M2420010000727
The multimode keyless entry system is installed.
There are the following features.
•Transmitter has two buttons (LOCK/UNLOCK).
•The ETACS-ECU is equipped with the integral
receiver and receiving antenna.
•Up to 4 encrypted codes (4 transmitters) can be
registered using M.U.T.-III.
•Answer-back function has been adopted.
•Using the LOCK/UNLOCK buttons, all doors
(including tailgate) can be locked or unlocked and
door mirrors can be retracted or opened.

• Door lock actuators (lock/unlock)
• Door mirror assembly (unfolding/folding)
• The signal causes the room lamp to flash once when the doors are locked\
, or come on for 15 seconds when unlocked.
• The signal causes the hazard warning lamp to flash once when the doors \
are locked, or flash twice when unlocked.
