COLUMN SWITCH
GENERAL INFORMATIONM2546100200058
Column switch has a function to ensure the driver's
safety during frontal collision of vehicle..
Function
If the column switch is moved to the front of the vehi-
cle and hit on the instrument panel or meter bezel by
the frontal collision of vehicle, the steering wheel is
moved to the front of the vehicle because the right
and left levers fall down, ensuring the driver's safety.
In addition, the column switch secures the rigidity
that the levers do not fall down by the normal opera
-
tion, however, it cannot be reused after the deforma-
tion.
RADIO AND CD PLAYER
GENERAL INFORMATIONM2544900200218
•Two types of audio, CD player with radio or 6-disk CD
changer with radio, have been established. The audio was
designed to create a uniformity impression with the instru
-
ment panel. Also, a new function automatically corrects the
sound quality and volume during driving.

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.

AUTO-CRUISE CONTROL SYSTEM
ENGINE AND EMISSION CONTROL17-5
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.
BLOCK DIAGRAM
Throttle position sensor (TP sensor)Informs the ECM of the throttle valve opening angle.
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.

SYSTEM FUNCTIONS
.
SET FUNCTION
1. During driving with the vehicle speed range from
approximately 40 to 200 km/h (25 to 125 mph),
press and release the "COAST/SET" switch.
2. The vehicle speed when the "COAST/SET" switch
is released is memorized. Thereafter, the constant
speed driving is performed at that vehicle speed.
3. When the "COAST/SET" switch is operated
during the driving with the vehicle speed of
approximately 200 km/h (125 mph) or more, the
constant speed driving will not be performed.
.
COAST FUNCTION
1. When the "COAST/SET" switch is continuously
pressed for 0.5 seconds or longer during constant
speed driving, the throttle valve becomes fully
closed while the switch is pressed, and the
vehicle is decelerated.
2. When the "COAST/SET" switch is released, the
vehicle speed at that time is now memorized.
Thereafter, the constant speed driving is
performed at that vehicle speed.
3. Also when the "COAST/SET" switch is pressed
for less than 0.5 second, the vehicle is
decelerated 1.6 km/h (1 mph) from the vehicle
speed of constant speed driving, and the
decelerated vehicle speed is now memorized.
Thereafter, the constant speed driving is
performed at that vehicle speed.
4. When the "COAST/SET" switch is continuously
pressed and the vehicle speed is decelerated to
approximately 40 km/h (25 mph) or less, the set
function and coast function are cancelled, and the
constant speed driving is cancelled.
.
RESUME FUNCTION
1. When the "CANCEL" switch is pressed or the
brake pedal is depressed during the constant
speed driving, it cancels the constant speed
driving.
2. Subsequently, when the "ACC/RES" switch is
pressed during driving with the vehicle speed of
approximately 40 km/h (25 mph) or more, the
constant speed driving is performed with the
vehicle speed memorized at the last cancellation
of constant speed driving.
.
ACCEL FUNCTION
1. When the "ACC/RES" switch is continuously
pressed for 0.5 second or more during constant
driving, it accelerates the vehicle with specified
acceleration while the switch is pressed.
2. Then, when the "ACC/RES" switch is released,
the vehicle speed at that time is now memorized.
Thereafter, the constant speed driving is
performed at that vehicle speed.
3. Also, when the "ACC/RES" switch is pressed for
less than 0.5 second, the vehicle is accelerated
1.6 km/h (1 mph) from the vehicle speed of
constant speed driving, and the accelerated
vehicle speed is now memorized. Thereafter, the
constant speed driving is performed at that
vehicle speed.
4. It is possible to keep pressing the "ACC/RES"
switch until the vehicle speed is accelerated to
approximately 200 km/h (125 mph) or above.
However, after the "ACC/RES" switch is released,
the vehicle speed of approximately 200 km/h (125
mph) becomes the newly memorized vehicle
speed. Thereafter, the constant speed driving is
performed at that speed.
.
CANCEL FUNCTION
When any of the following conditions are satisfied,
the constant speed driving will be cancelled.
•The auto-cruise control system is stopped by the
pressing the "ON OFF" switch.
•The "CANCEL" switch is pressed.
•The brake pedal is depressed.
•The clutch pedal is depressed .
•The selector lever is shifted to the "N" position
.
•The vehicle speed becomes approximately 40
km/h (25 mph) or less.
•The vehicle speed is reduced 15 km/h (9 mph) or
more from the speed at which the constant speed
driving was started.
•An abnormality occurs in the vehicle speed sig-
nal.
•The engine coolant temperature becomes abnor-
mally high.
•An abnormality occurs to the ECM.
•An abnormality occurs to the TCM .
•An abnormality occurs to the CAN communica-
tion.
