Turn ignition switch from “OFF” to
“ON” position.Drive vehicle.
Turn ignition switch from “ON” to
“OFF” position.Disconnect battery negative cable.
Do not start engine, or check with
engine stopped.Depress brake pedal.
Start engine, or check with engine run-
ning.Release brake pedal.
Apply parking brake. Depress accelerator pedal.
Release parking brake. Release accelerator pedal.
Check after engine is warmed up suffi-
ciently.Pin terminal check for SMJ type ECM
and TCM connectors.
For details regarding the terminal
arrangement, refer to the “ELEC-
TRICAL UNITS” electrical reference
page at the end of the manual. Voltage should be measured with a
voltmeter.
Circuit resistance should be measured
with an ohmmeter.
Current should be measured with an
ammeter.

CYLINDER BLOCK


Main bearing with an oil hole and groove goes on cylinder
block. The one without them goes on lower cylinder block.

Only main bearing (on cylinder block) for No. 3 journal has dif-
ferent specifications.

Before installing main bearings, apply new engine oil to the
bearing surface (inside). Do not apply new engine oil to the
back surface, but thoroughly clean it.

When installing, align main bearing stopper to the notch.

Ensure the oil holes on cylinder block and those on the corre-
sponding bearing are aligned.
4. Install signal plate to crankshaft if removed.
a. Position crankshaft and signal plate using a dowel pin, and
tighten mounting bolts.
b. Remove dowel pin.
CAUTION:
Be sure to remove dowel pin.
NOTE:
Dowel pin of crankshaft and signal plate is provided as a set for
each. If dowel pin is not available (when reusing crankshaft and
signal), use M6 bolt [length 10 mm (0.39 in) or more] as a substi-
tute.
5. Install crankshaft to cylinder block.

While turning crankshaft by hand, make sure that it turns smoothly.
6. Install lower cylinder block with the following procedure:
a. Apply liquid gasket with a tube presser (special service tool:
WS39930000) to lower cylinder block as shown in the figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
After liquid gasket is applied, rear oil seal installation must
be finished within 5 minutes. Therefore, the following pro-
cedure must be performed quickly.
NOTE:
Lower cylinder block cannot be replaced as a single part,
because it is machined together with cylinder block.
b. Tighten lower cylinder block mounting bolts with the following
procedure:
i. Apply new engine oil to threads and seat surfaces of mounting bolts.
ii. Tighten M8 bolts in numerical order from No. 11 to 22 in the fig-
ure.
NOTE:
There are more processes to complete the tightening of mount-
ing bolts. However stop procedure here to install rear oil seal.
c. Install rear oil seal. Refer to EM-65, "
Removal and Installation of Rear Oil Seal" .
d. Restart tightening of lower cylinder block mounting bolts with the following procedure:

ENGINE CONTROL SYSTEM

SYSTEM DESCRIPTION
This system improves engine operation when the air conditioner is used.
Under the following conditions, the air conditioner is turned off.

When the accelerator pedal is fully depressed.

When cranking the engine.

At high engine speeds.

When the engine coolant temperature becomes excessively high.

When operating power steering during low engine speed or low vehicle speed.

When engine speed is excessively low.

When refrigerant pressure is excessively low or high.
Fuel Cut Control (at No Load and High Engine Speed)EBS010LC
INPUT/OUTPUT SIGNAL CHART
*: This signal is sent to the ECM through CAN communication line.
SYSTEM DESCRIPTION
If the engine speed is above 1,800 rpm under no load (for example, the shift position is neutral and engine
speed is over 1,800 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies
based on engine speed.
Fuel cut will be operated until the engine speed reaches 1,500 rpm, then fuel cut will be cancelled.
NOTE:
This function is different from deceleration control listed under Multiport Fuel Injection (MFI) System, EC-34
.
CAN Communication UnitEBS010LD
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.

Method B
1. Remove No. 1 ignition coil.
2. Connect No. 1 ignition coil and No. 1 spark plug with suitable
high-tension wire as shown, and attach timing light clamp to this
wire.
3. Check ignition timing.
Accelerator Pedal Released Position LearningEBS010LF
DESCRIPTION
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accel-
erator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time
harness connector of accelerator pedal position sensor or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.

3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON and wait at least 2 seconds.
5. Turn ignition switch OFF and wait at least 10 seconds.
Throttle Valve Closed Position LearningEBS010LG
DESCRIPTION
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by
monitoring the throttle position sensor output signal. It must be performed each time harness connector of
electric throttle control actuator or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.
Idle Air Volume LearningEBS010LH
DESCRIPTION
Idle Air Volume Learning is an operation to learn the idle air volume that keeps each engine within the specific
range. It must be performed under any of the following conditions:

Each time electric throttle control actuator or ECM is replaced.

Idle speed or ignition timing is out of specification.
PREPARATION
Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.

Battery voltage: More than 12.9V (At idle)

Engine coolant temperature: 70 - 95°C (158 - 203°F)

PNP switch: ON

Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, set lighting switch to the 1st position to light
only small lamps.

Steering wheel: Neutral (Straight-ahead position)

Vehicle speed: Stopped

Transmission: Warmed-up
For A/T models with CONSULT-II, drive vehicle until “FLUID TEMP SE” in “DATA MONITOR” mode of “A/
T” system indicates less than 0.9V.
For A/T models without CONSULT-II and M/T models, drive vehicle for 10 minutes.
OPERATION PROCEDURE
With CONSULT-II
1. Perform EC-45, "Accelerator Pedal Released Position Learning" .
2. Perform EC-46, "
Throttle Valve Closed Position Learning" .
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
5. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode.
