GENERAL DESCRIPTION
ENGINE LUBRICATION12-2
GENERAL DESCRIPTIONM2120000100249
The lubrication system is a full-flow, filter pumping
system.
The engine oil that accumulates in the oil pan is
drawn and discharged by the oil pump. After its pres
-
sure is regulated by the relief valve, the oil passes
through the oil filter. Then, it flows from the oil pas
-
sage in the cylinder block to the individual crankshaft
journals and the cylinder head.
After the oil is pumped to the individual crankshaft
journals, it passes through a passage in the crank
-
shaft and is fed to the pins. After the oil is pumped to
the cylinder head, it flows to the camshaft journals
and the engine oil control valves.

GENERAL INFORMATION
FRONT AXLE26-2
GENERAL INFORMATIONM2260000100819
For the front axle, a double-row angular contact ball
bearing with an integral oil seal is adopted as a
wheel bearing, and EBJ-ETJ type constant velocity
joint as a driveshaft.
It has the following features:
•The driveshaft incorporates lightweight and com-
pact EBJ-ETJ type constant velocity joints.
•Lead-free grease for the constant velocity joint is
adopted.
•Hexavalent chromium is eliminated from the dust
cover material.
•The number of parts is reduced by integrating the
magnetic encoder for ABS wheel speed detection
into the wheel bearing.
NOTE: .
ETJ (High Efficiency Compact Tripod Joint): the
lighter and smaller constant velocity joint com
-
pared with the conventional TJ has been
installed.
EBJ (High Efficiency Compact Birfield Joint): the
lighter and smaller constant velocity joint com
-
pared with the conventional BJ has been
achieved by adopting the eight small balls.

NOTE: *: Indicates the distance between each joint
center.

CONSTRUCTION DESCRIPTION
SENSORM2351001000494
Wheel speed sensor
The wheel speed sensor is a kind of a pulse genera-
tor. It consists of the magnetic encoder for wheel
speed detection (a plate on which north and south
pole sides of the magnets are arranged alternately)
which rotates at the same speed of the wheel and
the wheel speed sensor (semiconductor sensor).
This sensor outputs frequency pulse signals in pro
-
portion to the wheel speed.
The front wheel speed sensor consists of the front
wheel speed sensor mounted on the knuckle and the
magnetic encoder for wheel speed detection which is
press-fitted together with the oil seal to the front
wheel bearing. The rear wheel speed sensor con
-
sists of the rear wheel speed sensor mounted on the
trailing arm assembly and the magnetic encoder for
wheel speed detection which is press-fitted together
with the oil seal to the rear wheel bearing.
ACTUATORSM2351002000356
ABS warning light, Brake warning light
The ABS system informs the driver of the ABS sys-
tem status by illuminating, extinguishing, or flashing
the ABS warning light and brake warning light as fol
-
lows.
ABS warning light
•Turns ON when a system malfunction occurs.
Brake warning light
•Turns ON when an EBD system malfunction
occurs.
NOTE: .
•Turns ON when the brake fluid level in the
reservoir tank becomes the specified value or
lower.
•Turns ON when the parking brake lever is
pulled and the brake is activated.

NOTE: *:ABS and brake warning lights remain illumi-
nated until the ignition is switched off.

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.

The MacPherson strut type 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.
•Increased suspension stroke improves road hold-
ing quality, and secures good adhesion even on
bumpy-rough roads to reduce shocks received
when the vehicle negotiates bumps.
•The fully flattened crossmember improves the
left/right direction rigidity of installation points of
the lower arms for high steering ability.
•Tuning of the lower arm bushes improves the
steering ability and riding comfort.
•The stabilizer bar is joined to the strut for high
efficiency to secure the optimum rolling rigidity,
and improves the steering ability.
