ENGINE CONTROL SYSTEM
Crankcase Ventilation System
EBS0036K
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 CommunicationEBS00NBH
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.

When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA-27,
"Changing Engine Coolant" . Also, replace the engine oil.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-18, "
Engine Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS004QV
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-1511,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1511,
"Diagnostic Procedure" .
3. Turn ignition switch “ON”.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II and make sure that cooling fans operate when touching
“HIGH” or “LOW”.
If NG, go to EC-1511, "
Diagnostic Procedure" .

FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY
3. Separate the fuel filter and fuel level sensor unit.
a. Fit a used O-ring into space between fuel level sensor unit and
fuel filter. Undo catches and separate fuel level sensor unit and
fuel filter.
●For reference when reassembling, put a mating mark on outer
edges of fuel level sensor unit and fuel filter with some means
which cannot be erased by fuel.
b. Insert blade end screwdriver to the gap between the fuel filter
and fuel level sensor unit to separate them.
CAUTION:
Put cloth or similar one on the edge of screwdriver not to
damage the inserted portion.
4. Remove pressure regulator from fuel filter.
a. Open and remove the clip.
b. Pull the pressure regulator straight out during removal.
CAUTION:
●Avoid impacts such as falling during removal.
●Do not disassemble or adjust.
ASSEMBLY
Install in the reverse order of removal paying attention to the following.
●Install the fuel filter and fuel pump with the tabs aligned, Make sure a click sound of secure engagement is
heard.
●Securely connect the harness connector of the fuel pump.
●Install the pressure regulator O-ring as follows.
CAUTION:
●When replacing, always use a new O-ring.
●Handle it with bare hands. (Do not use gloves.)
●Visually check the O-ring, mounting parts and mating parts for foreign materials and flaws.
●Before installing, apply new engine oil.
●To avid damage, do not apply an excessive force (pulling or starching).
●Install the pressure regulator as follows.
1. Insert the clip to the groove of the pressure regulator.
2. With the clip installed, insert the pressure regulator straight by
matching the fuel filter protrusion and the clip notch.
3. Make sure that the fuel filter protrusion and clip notch are
securely engaged.

CautionECS008BM
●Do not reuse transaxle oil, once it has been drained.
●Check oil level or replace oil with vehicle on level ground.
●During removal or installation, keep inside of transaxle clear of dust or dirt.
●Check for the correct installation status prior to removal or disassembly. If mating marks are required, be
certain they do not interfere with the function of the parts they are applied to.
●In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
●Be careful not to damage sliding surfaces and mating surfaces.
