CAUTION
When the connector is disconnected, it is normal
for short-circuiting to occur between the connec
-
tor terminals.
•The diagnosis spring is assembled on the
SRS-ECU wiring harness-side connector. When
the ECU-side connector is connected to the
SRS-ECU wiring harness-side connector, the
diagnosis spring is disengaged from the terminal
to short the circuit between the ECU-side con
-
nector terminals. The connector engagement is
detected electrically by flowing the monitor cur
-
rent to this circuit.
•This mechanism automatically short-circuits the
power supply side terminal and earth side termi
-
nal of the air bag when the connector is discon-
nected. A short spring is incorporated in the
connector to short-circuit the power supply side
terminal and earth side terminal of the air bag (no
potential difference between the two terminals)
and prevent flow of current by static electricity to
the squib.

GENERAL
ACTIVE STABILITY CONTROL SYSTEM (ASC)35C-2
GENERAL
M2357000200040
The active stability control system (ASC) has been
installed to the M/T vehicle.
•The active stability control system (ASC) has the
stability control and the traction control (TCL)
functions. By the integrated control with the
anti-lock brake system, the system stabilises the
vehicle attitude and at the same time secures the
driving force.
•When the stability control function determines
that the vehicle is in a dangerous condition, it
reduces the engine output and applies brake
force to four wheels independently to control the
vehicle behaviour, avoiding the critical state.
•The traction control (TCL) function prevents the
driving wheel slip on a slippery road surface,
ensuring easy startup, and at the same time,
secures proper driving force and improves steer
-
ing performance during cornering acceleration.
•Fail-safe function assures the security.
•Serviceability improvement
•For wiring harness saving and secure data com-
munication, the CAN* communication has been
adopted as a tool of communication with another
ECU.
NOTE: .
•*For more information about CAN (Controller
Area Network), refer to GROUP 54C
P.54C-2.
•ABS and ASC are controlled by ASC-ECU.

GENERAL INFORMATION
BASIC BRAKE SYSTEM35A-2
GENERAL INFORMATION
M2350000100848
FEATURES
Brake system with high reliability and durability have
achieved distinguished braking performance.
BRAKING PERFORMANCE
•Brake booster with 9-inch variable amplification
ratio mechanism by which greater braking force
can be obtained with a less pedal pressure has
been installed (with brake assist function).
•14-inch disc brake is installed on the front
wheels.
•15-inch disc brake is installed on the front
wheels.
•8-inch leading trailing type drum brake is installed
on the rear wheels.
•14-inch disc brake is installed on the rear wheels.

STABILITY
•4-wheel anti-lock braking system (4ABS) is
adopted to prevent slipping caused by the vehicle
wheels locking up, in order to maintain appropri
-
ate braking distance, and also to maintain vehicle
stability and steering function.
•Electronic brake-force distribution (EBD) is
adopted to maintain the maximum amount of rear
braking force even when the vehicle's load is var
-
ied.
•Diagonal split (X-type) brake fluid line is adopted.
•Ventilated discs have been adopted to front
brakes to improve anti-fading performance.
•A brake pedal retraction suppression structure
that restrains the retraction of the brake pedal
and reduces the shock to the feet of the driver in
the event of a frontal collision has been adopted.
SERVICEABILITY
•Diagnosis function is adopted for the ABS system
in order to make inspection easier.
•For the front disc brakes, brake disc separated
front hub is adapted to make removal and instal
-
lation easier.
•ABS-ECU and hydraulic unit have been inte-
grated to make them more compact and lighter.

CVT
CONTINUOUSLY VARIABLE TRANSMISSION (CVT)23-2
CVT
GENERAL INFORMATIONM2231000100165
The F1C1A transmission is adopted for the CVT.
This transmission is basically the same as conven
-
tional transmission.
The ATF warmer (ATF cooler) is adopted.

GENERAL INFORMATIONM2232000100447
•A smart shift type selector lever has been
adopted in order to facilitate walkthrough
between the seats.
•A gun grip type selector lever knob has been
adopted for better operation and easier visual
recognition of the switches arranged in the centre
panel.
•The selector lever assembly has been a single
unit made by aluminium die casting for better
accuracy and fewer parts, resulting in the light
-
weight and compact structure.
•The selector lever has been designed to be com-
pact and appropriately configured not to interfere
with the energy absorbing mechanism on the
steering column upon impact of the vehicle.
•In order to prevent abrupt start by erroneous
operation of selector lever, a CVT erroneous
operation prevention mechanism (the shiftlock
mechanism and key interlock mechanism) has
been adopted.

Operation
1.Whe n the sele ctor leve r is in th e P positio n, the
det ent pin is enga ged with the lock cam. Whe n
the push button on the selecto r lever is pressed ,
the detent pin moves in the d i rection A as illu s
-
trated in the figure to rot a te the lock cam.
2.Whe n the d e tent p i n rot a te s the lock cam t o dis-
engage, th e se lector lever can go over the pro-
truding p a rt of the d e tent b l ock. Th is e nables
sh
if ting the selector lever .

Only when the following two conditions are satisfied,
the selector lever can be shifted from the P position
to another position:•When the brake pedal is depressed
•When the ignition key is in other than the LOCK
(OFF) position
