CONSTRUCTION DESCRIPTION
FOUR-WHEEL ANTI-LOCK BRAKE SYSTEM (4ABS)35B-11
NOTE: .
•*1 This diagnostic trouble code is not set within
the vehicle speed of 20 km/h (12 mph) or less.
•*2 Turns ON when two or more wheels are faulty.
•*3 Stays ON until the vehicle speed reaches 10
km/h (6 mph) when the ignition switch is turned to
ON next time.
DIAGNOSTIC FUNCTION
ABS-ECU has the following functions for easier sys-
tem checks. The following items can be diagnosed
using scan tool.
•Diagnostic trouble code set
•Service data output
•Actuator test.
DIAGNOSTIC TROUBLE CODE SET
There are 43 diagnosis items. Since all the diagnos-
tic results are recorded in volatile memory
(EEPROM*), 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 diagnosis item, refer to Service Manual.
.
SERVICE DATA OUTPUT
Using scan tool, the input data sent from the sensors
and switches can be read.
NOTE: For service data items, refer to Service Man-
ual.

ACTUATOR TEST
Using scan tool, the actuators can be forcibly oper-
ated.
NOTE: .
•When ABS-ECU is disabled, the actuator test
cannot be performed.
•The actuator test can be performed only when
the vehicle is stationary. When the vehicle speed
reaches 10 km/h (6 mph), the forcible actuator
operation is disabled.
•During actuator test, the ABS warning light
flashes in 2Hz, and ABS control is prohibited.
•For the actuator test specification, refer to Ser-
vice Manual.

GENERAL INFORMATION
REAR SUSPENSION34-2
GENERAL INFORMATIONM2340000100977
The trailing arm type multi-link suspension is
adopted.
.
MAIN FEATURES
•The wheel tread is increased to improve corner-
ing ability.
•The roll center height is modified to improve the
steering ability.
•A double crossmember is adopted and the upper
arm, lower arm, toe control arm are joined to the
crossmember to improve suspension alignment
accuracy and maintenance performance.
•Improvement of arms installation accuracy elimi-
nates the camber adjustment to improve mainte-
nance performance.
•The trailing arm bushings are installed in the
upper position to improve the movement of the
suspension when the vehicle negotiates bumps
and increase riding comfort.
•Twin tube type shock absorber is adopted to
secure optimum rolling rigidity and improve the
steering ability.
•A high efficiency ball joint type stabilizer link is
adopted to improve steering ability.
•The toe control arm is installed in the lower posi-
tion to increase toe and camber rigidity and
improve steering ability.

GENERAL INFORMATION
REAR AXLE27-2
GENERAL INFORMATIONM2270000100478
The rear axle has the following features:
•The wheel bearing is a unit ball bearing (dou-
ble-row angular contact ball bearing) which incor-
porates the oil seals and is highly resistant to
thrust loads.
•The number of parts has been reduced by inte-
grating the magnetic encoder for ABS wheel
speed detection into the wheel bearing. -

GENERAL INFORMATION
POWER STEERING37-2
GENERAL INFORMATIONM2370000101003
FEATURES
A hydraulic power steering system has been adopted
to all models.
This steering system offers the following features:
•The support method of the steering gear to the
crossmember is realised by the left and right
internal bushings with inner cylinders. This sup
-
port method achieves higher rigidity of the steer-
ing gear and improves the steering feeling.
•Configuring the optimum flow characteristics and
gear valve feature improves the handling stability.
•Appropriate application of friction to the steering
gear cuts off the disturbance from the road sur
-
face and improves the stability during the
straight-ahead driving.
•Optimisation of the flexible tube in the high pres-
sure hose reduces the pump noise.

IMPACT-ABSORBING MECHANISM
.
Primary collision
If the vehicle is involved in a crash and impact energy is trans-
mitted to the lower shaft from the gearbox side, the intermedi-
ate shaft (A) will be pushed into intermediate shaft (B) to
absorb impact energy. Thus, the steering column will not be
projected into the passenger compartment.
