HEATER CONTROLLER
.
The features of the heater controller described below
have been designed for better appearance, easier
operation, and enhanced visibility.
•Each dial for the air outlet switching, fan volume
control, and temperature adjustment has been
enlarged to enhance operability.
•Ring lights have been adopted to inside the dials
to enhance appearance during nighttime. -
cles with automatic A/C>
•AUTO and OFF positions of the fan volume con-
trol dial have been exchenged with one another.
This change prevents the dial to pass the AUTO
position when the fan volume control is turned
OFF, and eliminates the necessity of manual
reselection when switching the inside/outside air
selection manually, thus enhancing the operabil
-
ity.
•When the air outlet switching dial and fan volume
control dial are turned to the AUTO position, the
A/C switch has been made to automatically turn
ON to enhance convenience. (Using the custom
-
ize function, this function can be cancelled. Refer
to
P.55-7.)

CYLINDER HEAD
A cylinder head made of an aluminum alloy, which is
lightweight and offers a high level of cooling effi
-
ciency, has been adopted. A pentroof combustion
chamber with a center spark plug has been adopted.
It has a small valve compound angle to realize a
compact chamber.
Cross-flow type intake and exhaust ports have been
adopted. Two intake ports and two exhaust ports are
provided independently on the right and left sides.
Five camshaft bearings are provided at the intake
and exhaust sides, respectively. The No. 4 bearing
sustains the thrust load of the camshaft. Only the No.
1 bearing uses a bearing cap that integrates both the
intake and exhaust sides.
VA LV E S E AT S
Sintered alloy valve seats have been adopted.The oversized (0.3 mm) service parts are available.
VA LV E G U I D E S
Valve guides that are common to both the intake and

COMPONENTS AND FUNCTIONS
ComponentFunction
Accelerator pedal position sensor (APP sensor)Informs the ECM of the accelerator pedal
depression.
Auto-cruise control switch"ON/OFF" switchPower switch for auto-cruise control system.
"ACC/RES" switchVehicle speed is set with the "ACC/RES" switch and
"COAST/SET" switch.
"COAST/SET" switch
"CANCEL" switchCancels the cruise speed setting.
Cancel systemClutch switch Because the constant speed driving is cancelled by
the clutch operation, the clutch pedal status is
detected.
Stoplight switch•Because the constant speed driving is canceled
by the brake operation, it detects the brake pedal
status.
•As for the stoplight switch, two built-in switches,
the stoplight switch which is also used for the
stoplight illumination and the brake switch which
is used exclusively for the auto-cruise control, are
integrated, and thus the reliability is enhanced.
Transmission range
switch Because the constant speed driving is cancelled by
the selector lever operation, it detects the "N"
position.
"CRUISE" indicator lightThe light is included in the combination meter and
illuminates when the "ON/OFF" switch is pressed
(auto-cruise control system: ON).
Data link connectorIf the M.U.T.-III scan tool is connected, the input
check code from the ECM can be read.
Engine control module (ECM)•Based on the input signal from each sensor and
switch, it outputs the throttle opening instruction
signal to the TAC motor.
•Based on the input signal from each sensor and
switch, it outputs the transaxle control signal to
the TCM .
•Based on the vehicle speed signal from the
vehicle speed sensor, it calculates the vehicle
speed .
•Based on the secondary pulley speed sensor
signal from the TCM, it calculates the vehicle
speed .
•Based on the selector lever "N" position signal of
the transmission range switch from the ECM, it
cancels constant speed driving. .
•Outputs the ON/OFF signals of "CRUISE"
indicator light and auto-cruise control system.
•The diagnostic trouble code signal is sent to the
"CRUISE" indicator light.
•The input check code is sent to the data link
connector.
Throttle actuator control motor (TAC motor)The throttle valve opens and closes in response to
the throttle angle signal from the ECM.

CONSTRUCTION AND OPERATIONM2170002000232
SYSTEM OUTLINE
The ECM calculates the auto-cruise control system
operation status when the ECM receives input sig
-
nals from the auto-cruise control switch, vehicle
speed and cancel system [stoplight switch and clutch
switch or transmission range switch ]. The engine control section sends the target acceler
-
ator pedal opening angle value for auto-cruise con-
trol system, the TCM issues a command to transaxle
control , and the gauge issues an ON/OFF
command for the "CRUISE" indicator light.
In the engine control section, the target throttle valve
opening angle value is calculated from the target
accelerator pedal opening angle value for
auto-cruise control system and the actual accelerator
angle value.The vehicle speed is then controlled by
applying the TAC motor.

Transaxle control module (TCM) •Based on the transaxle control signal from the
ECM, it controls the transaxle.
•Outputs the signal from the secondary pulley
speed sensor to the ECM.
•Transmits the selector lever "N" position signal
from the transmission range switch to the ECM.
Vehicle speed sensor Transmits the vehicle speed signal proportional to
the vehicle speed to the ECM.

FAIL-SAFE FUNCTION
When any of the following conditions are satisfied,
the auto-cruise control system function is stopped
until the system returns to normal. Also, when any of
the conditions are satisfied during the constant
speed driving, the constant speed driving is can
-
celled immediately.
•An abnormality occurs to the auto-cruise control
switch.
•An abnormality occurs to the stoplight switch.
When any of the following conditions are satisfied,
stop the vehicle once and turn the ignition switch to
"LOCK" (OFF). Otherwise, even when the system
returns to normal, the auto-cruise control system
function will continue to be stopped. Also, when any
of the conditions are satisfied during the constant
speed driving, the constant speed driving is can
-
celled immediately.
•ECM abnormality
•TP sensor abnormality
•APP sensor abnormality
.
DIAGNOSIS FUNCTION
•The diagnostic trouble code check is possible
with the "CRUISE" indicator light.
•To facilitate the system check, check the service
data output with the M.U.T.-III.
NOTE: For diagnostic items, service data output
items, and check method, refer to the Service Man
-
ual.

MULTIPORT FUEL SYSTEM (MFI)13A-22
GENERATOR L TERMINAL
After turning on the ignition switch, the current is input by the
ECM to the generator L terminal. This allows the IC regulator to
be on and the field coil to be excited. When the generator
rotates in this situation, the voltage is excited in the stator coil
and the current is output from B-terminal through the commuta
-
tion diode. Also the generated voltage is input to the voltage
regulator through the commutation diode. After the electric gen
-
eration begins, the current is supplied to the field coil from this
circuit. In addition, the generated voltage is output from the
generator L terminal to the ECM. This allows the ECM to detect
that the electric generation begins. The ECM outputs the ON
signal to the combination meter through the CAN and then
turns off the generator malfunction light.

EVAPORATIVE EMISSION VENTILATION
SOLENOID
The evaporative emission ventilation solenoid, an ON/OFF
type solenoid valve, is integrated in the evaporative canis
-
ter.The evaporative emission ventilation solenoid is installed
between the evaporative canister and the air-releasing end,
where the evaporative emission ventilation solenoid takes or
shuts off air.When the current is not flowing through the coil, the
air flows between the nipples, "A" and "B", and through the
evaporative canister.When the current is flowing through the
coil, the air is sealed in the nipple "A" and the air through the
evaporative canister is shut off.When monitoring the evapora
-
tive leak, the ECM turns the evaporative emission ventilation
solenoid on to create the slight vacuum condition in the evapo
-
rative emission control system. The ECM shuts off the air flow-
ing through the evaporative canister to maintain the vacuum
condition necessary for monitoring.
