Crankcase Ventilation SystemEBS011X4
DESCRIPTION
In this system, blow-by gas is sucked into the air duct after oil separation by oil separator in the rocker cover.
INSPECTION
Ventilation Hose
1. Check hoses and hose connections for leaks.
2. Disconnect all hoses and clean with compressed air. If any hose
cannot be freed of obstructions, replace.
CAN CommunicationEBS01H7B
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN COMMUNICATION UNIT
Go to CAN system, when selecting your CAN system type from the following table.

REMOVAL
WARNING:
Be sure to read “General Precautions” when working on the fuel system. Refer to FL-3, "
General Pre-
cautions" .
1. Perform the steps 1 to 7 of “REMOVAL” in “ FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL
PUMP ASSEMBLY”. Refer to FL-4, "
REMOVAL" .
2. Drain fuel more from fuel tank if necessary.
CAUTION:
Because fuel tank forwardly inclines and becomes unstable when installing/removing, fuel should
be drained if found the remaining quantity.
3. Remove exhaust center tube and insulator. Refer to EX-2, "
EXHAUST SYSTEM" .
4. Remove propeller shaft. (4WD models) Refer to PR-3, "
REAR PROPELLER SHAFT" .

5. Using a transmission jack, support the bottom of final drive
assembly (4WD models) or rear suspension member (2WD
models).
6. Remove mounting nuts on rear suspension member, and lower
the transmission jack carefully until just before rear suspension
member is removed from stud bolts on the vehicle. Refer to
RSU-5, "
REAR SUSPENSION ASSEMBLY" .
7. Disconnect fuel filler hose, EVAP hose and vent hose at fuel
tank side.

For disconnection procedure of quick connector on EVAP
hose, refer to FL-4, "
FUEL LEVEL SENSOR UNIT, FUEL FIL-
TER AND FUEL PUMP ASSEMBLY" .
8. Remove fuel tank protector.
9. Remove fuel tank band mounting bolts while supporting fuel
tank.
CAUTION:
Sustain the bottom of fuel tank by using plate or anything
same.
10. Remove fuel tank.

After lifting down the front portion of fuel tank, remove fuel
tank by pulling it from the upper front of final drive assembly,
so that fuel tank can move forwardly.
CAUTION:
Pay attention not to fall fuel tank because it forwardly
inclines and becomes unstable.
NOTE:
It is desirable that more than two technicians work together.
INSTALLATION
Note the following, and install in the reverse order of removal.

Surely clamp fuel hoses and insert hose to the length below.

Be sure hose clamp is not placed on swelled area of fuel tube.

Tighten fuel hose clamp so that the remaining length of screw thread becomes to the following.

Fit fuel tank band pin to the vehicle side securely.

Before fixing fuel tank, temporarily install fuel filler tube.
