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.

GENERAL INFORMATION
M2551000100759
For the heater and A/C system, the heater, the
blower and the cooling unit are integrated as one unit
to reduce weight and size. For A/C system, the man
-
ual A/C has been adopted.
FEATURES
IMPROVEMENTS IN COMFORT
•Adoption of low noise, large air volume heater
and A/C system
•Adoption of smaller air intake box for larger pas-
senger leg space.
•Optimising the areas of the outside air induction
hole and the air outlet improves ventilation per
-
formance as well as the quietness of the room
•Adoption of clean air filter with deodorant function
for cleaner air in the compartment.
IMPROVEMENTS IN OPERATION
PERFORMANCE
•Inside/outside air selection switch has been
changed to a pushbutton switch.
•Improved operation ability by the enlarged tab on
the dial knob
•Air amount and temperature only are controlled
automatically for easier operation. automatic A/C>
RELIABLE VISUAL FIELD
(IMPROVEMENT IN SAFETY)
•Current type defroster nozzle has been adopted
to improve defogging performance (Shortens
windshield fogging time).
•Defroster vents have been integrated to secure
better defogging pattern.
•Black coin drop prevention ribs are used on the
defroster to prevent its reflection on the wind
-
shield, providing sufficient field of vision for safety
IMPROVEMENTS IN FUEL ECONOMY
•Wider condenser area reduces load to the A/C
and improves fuel consumption.
•Energy conservation control using outside air
temperature sensor is adopted for vehicles with
manual A/C as well.
•A small-size, highly-efficient compressor has
been adopted.
•Simpler wiring and weight reduction are achieved
by installation of CAN communication system
GLOBAL ENVIRONMENT PROTECTION
Adoption of HFC134a for refrigerant.
IMPROVEMENTS IN SERVICE QUALITY
•Reduction of refrigerant gas leakage and
improvement in serviceability by incorporating
condenser and receiver
•The layout of refrigerant line for better workability
is adopted.
RESPONSIBILITY IMPROVEMENT
Reliable information transmission is achieved by
connecting A/C-ECU and each ECU via CAN com
-
munication.

COMMUNICATION
The A/C receives the following kinds of signals
through CAN communication.
