1. When connecting the vacuum hoses, they should be
securely inserted onto the nipples.
2. Connect the hoses correctly, using the VACUUM HOSE
ROUTING diagram as a guide.

VACUUM HOSE CHECKM1173007300171
1. Using the VACUUM HOSE ROUTING diagram as a guide,
check that the vacuum hoses are correctly connected.
2. Check the connection of the vacuum hoses, (removed,
loose, etc.) and confirm that there are no sharp bends or
damage.
POSITIVE CRANKCASE VENTILATION SYSTEM
GENERAL DESCRIPTION (POSITIVE CRANKCASE VENTILATION SYSTEM)M1173005000293
The positive crankcase ventilation (PCV) system pre-
vents the escape of blow-by gases from inside the
crankcase into the atmosphere.
Fresh air is sent from the air cleaner into the crank-
case through the breather hose to be mixed with the
blow-by gas inside the crankcase.
The blow-by gas inside the crankcase is drawn into
the intake manifold through the PCV valve.The PCV valve is designed to lift the plunger accord-
ing to the intake manifold vacuum so as to regulate
the flow of blow-by gas properly.
In other words, the blow-by gas flow is regulated dur-
ing low load engine operation to maintain engine sta-
bility, while the flow is increased during high load
operation to improve the ventilation performance.

EVAPORATIVE EMISSION CONTROL SYSTEM
GENERAL DESCRIPTION (EVAPORATIVE EMISSION SYSTEM)M1173005100706
The evaporative emission (EVAP) system prevents
fuel vapors generated in the fuel tank from escaping
into the atmosphere.
Fuel vapors from the fuel tank flow through the vapor
pipe/hose to be stored temporarily in the EVAP can-
ister.
When the vehicle is in operation, fuel vapors stored
in the EVAP canister flow through the EVAP purge
solenoid, purge port and intake manifold plenum to
the combustion chamber.When the engine coolant temperature is low or when
the intake air quantity is small (when the engine is at
idle, for example), the Engine-ECU brings the EVAP
purge solenoid into the OFF state to shut off the fuel
vapor flow to the intake manifold plenum. This
ensures driveability when the engine is cold or run-
ning under low load and also stabilizes the emission
level.

GENERAL DESCRIPTION
FRONT AXLE26-2
GENERAL DESCRIPTIONM1261000100370
The front axle consists of front hubs, knuckles, wheel
bearings and drive shafts, and has the following fea-
tures:
The wheel bearing incorporates double-row
angular contact ball bearing for reduced friction.
The front wheel hub assembly combines the hub,
wheel bearing, and oil seal in a single unit for
fewer parts, better durability, improved assembly
precision, and better structural organization.
The driveshaft incorporates BJ-PTJ type constant
velocity joints with high transmission efficiency for
low vibration and noise.
Due to the use of the inner shaft and bracket
assembly, the right and left drive shafts are
approximately the same in length. This reduces
noise, vibration and torque steer.L-RH>
The dynamic damper is mounted on the LH drive-
shaft.
ABS rotor for detecting the wheel speed is
press-fitted to the BJ.

TROUBLESHOOTING STRATEGYM1261005600240
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find a front axle fault.
1. Gather information from the customer.

GENERAL DESCRIPTION
REAR AXLE27-2
GENERAL DESCRIPTIONM1271000100326
The rear axle has the following features:
The wheel bearing incorporates a unit ball bear-
ing (double-row angular contact ball bearing) for
reduced friction.
The rear wheel hub assembly combines the hub,
wheel bearing, and oil seal in a single unit for
fewer parts, better durability, improved assembly
precision, and better structural organization.
ABS rotor for detecting the wheel speeds is
press-fitted to the rear hub.

DIAGNOSTIC TROUBLE CODE PROCEDURES
(P0713): Transmission Fluid Temperature Sensor System (Open Circuit)
.
CIRCUIT OPERATION
The A/T-ECU connector B-22 (terminal 6) applies
5 volts to the transmission fluid temperature sen-
sor output terminal (terminal 1).
The transmission fluid temperature sensor circuit
is grounded to the A/T-ECU connector B-22 (ter-
minal 12).
When the transmission fluid temperature is cold,
the transmission fluid temperature sensor resis-
tance is high. When the transmission fluid tem-
perature is hot, the transmission fluid
temperature sensor resistance is low.
.
DTC SET CONDITIONS
Check Conditions
Engine speed: 1,000 r/min or more.
Output speed: 1,000 r/min or more.
Accumulated time in above condition: 10 min-
utes.
Judgement Criteria
Transmission fluid temperature sensor voltage:
4.5 volts or more. (1 second)
.
OBD-II DRIVE CYCLE PATTERN
Start the engine, drive at 60 km/h or more for 15 min-
utes in total.
