TRANSFER – TRANSFER ASSEMBLYTF–9
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.
2. INSTALL AUTOMATIC TRANSMISSION WITH
TRANSFER
HINT:
(See page AX-167)
3. INSTALL ENGINE AND TRANSAXLE
HINT:
(See page EM-44)
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.
Torque: 49 N*m (500 kgf*cm, 36 ft.*lbf)

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.

(f) 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.
(g) Start the engine.
(h) Using the intelligent tester, perform the speed
sensor signal check in Test Mode.
(i) Drive the vehicle straight forward.
(j) 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.
(k) 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.
• After the ABS warning light goes off and if
vehicle speed exceeds 50 mph (80 km/h), a
signal check code will be stored again.
Decelerate or stop the vehicle before the
speed reaches 50 mph (80 km/h).
• If the signal check has not been completed,
the ABS warning light blinks while driving
and the ABS system does not operate.
HINT:
When the signal check has been completed, the
ABS warning light goes off while driving and blinks
in the Test Mode pattern while stationary.
5. READ DTC
(a) Read the DTC(s) by following the tester screen.
HINT:
• Refer to the intelligent tester operator's manual
for further details.
• See the list of DTC.

TROUBLESHOOTING
HINT:
• Use this procedure to troubleshoot the engine immobiliser
system.
• The intelligent tester should be used in steps 4, 5 and 7.

NEXT
(a) Check for DTCs and note any codes that are output.
(b) Delete the DTC.
(c) Recheck for DTCs. Try to prompt the DTC (SFI system
and engine immobiliser system) by simulating the
original activity that the DTC suggested.
(1) If the DTC does not reoccur, proceed to A.
(2) If the DTC (SFI system) reoccurs, proceed to B.
(3) If the DTC (engine immobiliser system) reoccurs,
proceed to C.
