TF
INSTALLATION
1. INSTALL TRANSFER ASSEMBLY
(a) Apply sealant 1281 to the transaxle assembly and
transfer assembly in continuous beaded from of 1.2
mm diameter as shown in the illustration.
NOTICE:
• Wipe any grease off from the attaching
surfaces.
• Install it within 10 minutes after applying the
sealant.
• Sealant stuck on the gasket, case oil seal and
driving plug may cause oil leakage and
seizure due to oil shortage. Care must be
taken.
(b) Install the transfer assembly to the transaxle
assembly with the 2 bolts and 6 nuts.
Torque: 69 N*m (700 kgf*cm, 51 ft.*lbf)
NOTICE:
• Check that the gasket is installed to the
transfer assembly before installing them to
the transaxle assembly.
• Install the transfer assembly to the transaxle
assembly without tilting.
• When moving the transfer assembly, do not
hold the oil seal on the both sides.

4. INSTALL TRANSFER DRAIN PLUG
(a) Install the transfer drain plug with a new drain
gasket.
Torque: 49 N*m (500 kgf*cm, 36 ft.*lbf)
5. INSTALL NO. 2 TRANSFER CASE PLUG
(a) Install the No. 2 transfer case plug with a new No. 2
gasket.

TEST MODE PROCEDURE
1. SPEED SENSOR SIGNAL CHECK (WHEN USING SST
CHECK WIRE):
HINT:
• If the ignition switch is turned from the ON to the ACC
or LOCK position during Test Mode, the DTCs of the
signal check function will be erased.
(a) Turn the ignition switch off.
(b) Check that the steering wheel is in the straight-
ahead position and move the shift lever to the P
position (Automatic Transmission) or apply the
parking brake (Manual Transmission).
(c) Using SST, connect terminals TS and CG of the
DLC3.
SST 09843-18040
(d) Turn the ignition switch to the ON position.
(e) Check that the ABS warning light is blinking in the
Test Mode.
HINT:
If the ABS warning light does not blink, inspect the
TS and CG terminal circuit and the ABS warning
light circuit.
(f) Start the engine.
(g) Using SST, perform the speed sensor signal check
in Test Mode.
SST 09843-18040
(h) Drive the vehicle straight forward.
(i) Accelerate the vehicle to a speed of 28 mph (45 km/
h) or higher for several seconds and check that the
ABS warning light goes off.
HINT:
The signal check may not be completed if the
vehicle has its wheels spun.
(j) Stop the vehicle.
NOTICE:
• The speed sensor signal check may not be
completed if the steering wheel is turned or
the wheels are spun during the check.

• Vehicle was driven in the city area (or on free-
way) for 10 minutes or more.
(b) Monitor Conditions
(1) Turn the ignition switch off and wait for 6 hours.
HINT:
Do not start the engine until checking Readiness
Monitor status. If the engine is started, the step
described above must be repeated.
(c) Monitor Status
(1) Connect an intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Turn the tester or scan tool ON.
(4) Check the Readiness Monitor status displayed
on the tester or scan tool.
If the status does not switch to COMPL
(complete), restart the engine, make sure that
the preconditions have been met, and then
perform the Monitor Conditions again.
4. A/F SENSOR AND HO2S MONITORS
(a) Preconditions
The monitor will not run unless:
• 2 minutes or more have elapsed since the engine
was started.
• The Engine Coolant Temperature (ECT) is 75
C
(167
F) or more.
• Cumulative driving time at a vehicle speed of 30
mph (48 km/h) or more exceeds 6 minutes.
• Air-fuel ratio feedback control is performed.
• Fuel-cut control is performed for 8 seconds or
more (for the Rear HO2 Sensor Monitor).
(b) Drive Pattern for front A/F sensor and HO2 sensor.
(1) Connect an intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Turn the tester ON.
(4) Clear the DTCs.
(5) Start the engine, and warm it up until the ECT
reaches 75
C (167F) or higher.
(6) Drive the vehicle at 38 mph (60 km/h) or more
for at least 10 minutes.
(7) Change the transmission to the 2nd gear.
(8) Accelerate the vehicle to 40 mph (64 km/h) or
more by depressing the accelerator pedal for at
least 10 seconds (Procedure "A").
(9) Soon after performing procedure "A" above,
release the accelerator pedal for at least 4
seconds without depressing the brake pedal, in
order to execute fuel-cut control (Procedure "B").
(10) Allow the vehicle to decelerate until the vehicle
speed declines to less than 6 mph (10 km/h)
(Procedure "C").
(11) Repeat procedures from "A" through "C" above
at least 3 times in one driving cycle.

ES–422GR-FE ENGINE CONTROL SYSTEM – SFI SYSTEM
ES
In order to enhance OBD function on vehicles and
develop the Off-Board diagnosis system, CAN
communication is introduced in this system (CAN:
Controller Area Network). It minimizes a gap
between technician skills and vehicle technology.
CAN is a network, which uses a pair of data
transmission lines, spanning multiple computers
and sensors. It allows a high speed communication
between the systems and to simplify the wire
harness connection.
Since this system is equipped with the CAN
communication, connecting the CAN VIM (VIM:
Vehicle Interface Module) with an intelligent tester is
necessary to display any information from the ECM.
(Also the communication between the intelligent
tester and the ECM uses CAN communication
signal.) When confirming the DTCs and any data of
the ECM, connect the CAN VIM between the DLC3
and the intelligent tester.
2. NORMAL MODE AND CHECK MODE
(a) The diagnosis system operates in normal mode
during normal vehicle use. In normal mode, 2 trip
detection logic is used to ensure accurate detection
of malfunctions. Check mode is also available as an
option for technicians. In check mode, 1 trip
detection logic is used for simulating malfunction
symptoms and increasing the system's ability to
detect malfunctions, including intermittent problems
(intelligent tester only) (See page ES-43).
3. 2 TRIP DETECTION LOGIC
(a) When a malfunction is first detected, the
malfunction is temporarily stored in the ECM
memory (1st trip). If the same malfunction is
detected during the next subsequent drive cycle, the
MIL is illuminated (2nd trip).
4. FREEZE FRAME DATA
(a) The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC
is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle
was running or stopped, whether the engine was
warmed up or not, whether the air-fuel ratio was
lean or rich, as well as other data recorded at the
time of a malfunction.
