GENERAL INFORMATION
MULTIPOINT FUEL INJECTION (MPI) <4G1>13B-6
Camshaft position sensorThis sensor detects the top-dead-center (TDC) of the
compression stroke of each cylinder.
Crank angle sensorThis sensor detects the crank angle and inputs it into
the engine-ECU. The engine-ECU effects injector
control and other controls in accordance with the
signals received from this sensor.
Detonation sensorThis sensor, which contains a piezoelectric element,
detects the vibration of the cylinder block that results
from knocking. The engine-ECU detects only the
knocking of the engine from these vibrations, in order
to retard the ignition timing in accordance with the
strength of the knocks.
Alternator FR terminalThis terminal is used for detecting the duty cycle ratio
that energizes the alternator field coil.
Stop lamp switchThis is a contact point type switch that detects how
the brake pedal is depressed.
Actuators
Engine control relayThis relay turns ON and OFF the engine-ECU power
circuit.
Throttle valve control servo relayThis relay turns ON and OFF the actuation power
circuit for the throttle valve control servo in the
engine-ECU.
InjectorThe injectors inject fuel in accordance with the
injection signals received from the engine-ECU.
Ignition coil (with power transistor)Applies ignition coil primary current intermittently in
accordance with the ignition signals received from
the engine-ECU, in order to generate high voltage for
ignition.
Fuel pump relayControls the power supplied to the fuel pump in
accordance with the signals received from the
engine-ECU.
A/C compressor relayControls the operation of the A/C compressor in
accordance with the signals received from the
engine-ECU.
Purge control solenoid valveControls the flow rate of the purge air introduced into
the inlet manifold in accordance with the signals
received from the engine-ECU.
Alternator G terminalControls the amount of current generated by the
alternator in accordance with the signals received
from the engine-ECU.
Cooling fan control relayControls the speed of the cooling fan in accordance
with the signals received from the engine-ECU.
Throttle valve control servoControls the throttle valve position in accordance with
the signals received from the engine-ECU.

side impact.
•Direct combination key cylinder and inside lock
cables for the front doors have been adopted to
improve safety upon impact.
IMPROVEMENTS IN OPERATION
QUALITY
•The central door locking system, which
locks/unlocks all the doors and the tailgate, is
adopted.
•"P" position shift linked door-unlock function has
been introduced to the central door locking sys
-
tem(F1C1A).
IMPROVEMENTS OF PRODUCT
PACKAGE AND APPEARANCE

DESCRIPTION OF STRUCTURE AND
OPERATION
CENTRAL DOOR LOCKING
•When the driver's door inner lock knob is oper-
ated to the lock position with all doors closed, all
the doors (including tailgate) will lock.
•The driver’s door can be opened by pulling the
driver’s door inner handle even when the driver’s
door inner lock knob is in the lock position. This
function is called "Override function". All doors
and tailgate can be unlocked at the same time
that the driver's door is opened.
KEY-IN PREVENTION FUNCTION
If the driver’s door remained open, it cannot be
locked even though the driver’s door key cylinder or
driver’s side inside lock knob is pushed. This pre
-
vents the ignition key from being left in the passenger
compartment.
"P" POSITION SHIFT LINKED
DOOR-UNLOCK FUNCTION
When the selector lever is shifted to the "P" (parking)
position, all the doors (including tailgate) will unlock,
improving passengers' conv enience during alighting.
Using an adjustment function*, "P" position shift
linked door-unlock function can be changed to
"Active", or "Inactive". The initial setting at factory is
"Inactive".
NOTE: *: "P" position shift linked door-unlock func-
tion can be changed as a customise function. Refer
to GROUP 54B, Customise Function
