Checking Fuel LinesEBS00KOS
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration.
If necessary, repair or replace damaged parts.
General PrecautionsEBS011T7
WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: INFLAMMABLE” sign in the workshop.
Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:
Before removing fuel line parts, perform the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-48, "FUEL PRESSURE RELEASE" (WITH
EURO-OBD) or EC-510, "
FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
–Disconnect negative battery terminal.
Always replace O-rings and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Do not tighten hose clamps excessively to avoid damaging hoses.
After connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.
After installing tubes, check if there are no fuel leaks at con-
nections in the following steps.
–Apply fuel pressure to fuel lines with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.
–Start engine and rev it up and check for fuel leaks at con-
nections.
For servicing “Evaporative Emission System” parts, refer to
EC-473, "
EVAPORATIVE EMISSION SYSTEM" (WITH EURO-
ODB) or EC-865, "
EVAPORATIVE EMISSION SYSTEM"
(WITHOUT EURO-OBD).

FUEL FILTER
Air BleedingEBS00BLB
After fuel filter is replaced and after fuel system components are
removed/installed, bleed air from fuel line as follows:
Move priming pump up and down to bleed air from fuel path.
When air is bled, pumping of priming pump becomes heavy stop
operation at that time.
Crank engine until it starts. Do not crank engine for more than
30 seconds.
If engine does not start, stop cranking and repeat step 1 above.
If engine does not operate smoothly after it has started, race it
two or three times.
If air cannot be bled easily (pumping of priming pump does not
become heavy), disconnect feed-side of hose between fuel filter and electronically controlled fuel pump.
After that, operate priming pump and confirm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine
mounting insulator.
Draining Water from Fuel FilterEBS00MRU
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:
Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.
Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mounting insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-18, "
Air Bleeding" .
5. Start engine and make sure there is no fuel leakage.

Checking A/T FluidECS004Q7
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50°C (86 to 122°F) using “COLD” range on A/
T fluid level gauge.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and note reading. If level is at low
side of either range, and A/T fluid to the A/T fluid charging pipe.
CAUTION:
When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far
as it will go.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using a stopper attached.
f. Remove A/T fluid level gauge and note reading. If reading is at
low side of range, add A/T fluid to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Recheck A/T fluid level at A/T fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on A/T
fluid level gauge.
CAUTION:
When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.
Firmly fix the A/T fluid level gauge to the A/T fluid charging pipe using a stopper attached.

OVERALL SYSTEM
Input/Output Signal of TCMECS00CTC
*1: Spare for vehicle speed sensor·A/T (revolution sensor)
*2: Spare for accelerator pedal position signal
*3: If these input and output signals are different, the TCM triggers the fail-safe function.
*4: Used as a condition for starting self-diagnostics; if self-diagnostics are not started, it is judged that there is some kind of error.
*5: Input by CAN communications.
*6: Output by CAN communications.
Line Pressure ControlECS004QF
TCM has various line pressure control characteristics to match the driving conditions.
An ON-OFF duty signal is sent to the line pressure solenoid valve based on TCM characteristics.
Hydraulic pressure on the clutch and brake is electronically controlled through the line pressure solenoid
valve to accommodate engine torque. This results in smooth shift operation.
NORMAL CONTROL
The line pressure to throttle opening characteristics is set for suitable
clutch operation.
