CONSTRUCTION DESCRIPTION
ANTI-SKID BRAKE SYSTEM (ABS)35B-10
NOTE: .
•*: If any trouble occurs in CAN communication,
the brake warning lamp and ABS warning lamp
on the combination meter turns ON.
•Prohibit: Any controls are not performed until the
ignition switch is turned OFF.
•System shut-down: Control will be disabled until
valve power supply is turned off, and then ignition
switch is turned to the OFF position.
•Wait: ABS control is restarted when the normal
condition is resumed even though the ignition
switch is not turned OFF.
DIAGNOSTIC FUNCTION
ABS-ECU has the following functions for easier sys-
tem checks. The following items can be diagnosed
using the M.U.T.-III (ABS warning lamp illuminates
and ABS control is prohibited while the ABS-ECU
communicates with the M.U.T.-III).
•Diagnosis code set
•Service data output
•Actuator test
DIAGNOSIS CODE SET
There are 28 diagnostic items. Since all the diagnos-
tic results are recorded in volatile memory (EEP-
ROM*), they are stored in the memory even though
the battery terminals are disconnected.
NOTE: .
•*EEPROM (Electrical Erasable &;Programmable
ROM): Special type of memory that can be pro
-
grammed or erased electrically
•For each diagnostic item, refer to Fail-safe Func-
tion.

Employment of the parking brake pedal clears front
centre space to allow a walk through design.
PUSH-ON/PUSH-RELEASE type pedal has been
installed for easier operation.
The parking brake pedal retreat suppression mecha-
nism that restraints the retraction of the brake pedal
during collision has been adopted in order to reduce
the shock to the driver's feet. The mechanism of the
parking brake pedal is basically the same as that of
the brake pedal.

IMPROVED SERVICEABILITY
•Employment of an automatic hydraulic timing belt
tensioner offers timing belt reliability, reduced
operating noise, and better serviceability. <4G1>
•Wiring harness section of the crank angle sensor
has been moulded integrally with the timing belt
cover, improving serviceability and reliability.
<4G1>
•Due to the adoption of the timing chain and the
timing chain tensioner, maintenance-free and reli
-
ability have been improved. <4A9>
•Since adoption of unvolatile memory (EEPROM*)
helps the learned value not to be initialised when
the battery terminal or connector of the control
unit is disconnected, maintainability can be
improved.
NOTE: *EEPROM: Electrical Erasable Programma-
ble ROM (information to be memorised can be
electronically written into and erased from ROM)
•Since the adoption of electric power steering
makes hydraulic pipes and oil pumps unneces
-
sary, maintainability can be improved.
•Employment of operative A/C piping layout and
refrigerant leak detection system enhances serv
-
iceability.

CUSTOMISE FUNCTION
M2541006000243
Using M.U.T.-III adjusts the following function. The
programmed information is held even when the bat
-
tery is disconnected.
•Vehicle speed-dependent wiper function
With the windshield wiper switch in the intermittent
position, the intermittent duration changes
depending on the intermittent adjusting knob
position and the vehicle speed.
•The selector "P" position-linked central door
unlocking function
When the selector lever is shifted to the "P" position,
all the doors unlock.
•Turn-signal lamp operation sound function
Synchronized with the hazard lamp and the turn sig-
nal lamp, the buzzer sounds.
•Dimmer interior lamp control duration
When the door is closed with the ignition switch
LOCK (OFF), the interior lamp is turned OFF
automatically in the specified time.
•Timer lock time after executing the keyless entry
unlock
If any door including a tailgate is not opened after
being unlocked with the keyless transmitter,
doors are locked automatically within the speci
-
fied time.
•Door-ajar warning function
Driving with any door, including a tailgate, not prop-
erly closed sounds the buzzer to let the driver
know the door-ajar state.
•Rear wiper intermittent duration
When the rear wiper switch is turned ON, the rear
wiper operates in the intermittent action. When
the rear wiper switch is turned from OFF to ON
two cycles, the rear wiper makes continuous
operation regardless of the intermittent operation
duration setting.
•Wiper linked with washer function
When this function is active, the windshield wiper
operates if the washer switch is turned ON.
•Hazard answer back function of the keyless entry
system
When lock/unlock is operated with the keyless entry
transmitter, the horn sounds so that the driver can
recognize the lock/unlock status of the vehicle
even if the driver is away from it.
•Initialising all functions (Returning to the initial
condition)
All adjusting functions are returned to the settings at
the time of factory shipment.
