(d) Using SST, turn the differential assembly right and
left 2 or 3 times to allow the bearing to settle.
SST 09564-32011
(e) Using SST and a torque wrench, measure the
turning torque of the differential.
SST 09564-32011
Torque: Standard turning torque at 60 rpm
0.20 to 0.69 N*m (2.0 to 7.0 kgf*cm, 1.8
to 6.1 in.*lbf)
HINT:
If the turning torque is not within the specified value,
refer to the table below and select a thrust washer
so that the turning torque is within the specified
value.

(f) Remove the 16 bolts and the transaxle housing.
(g) Remove the differential assembly.
7. INSTALL FRONT DIFFERENTIAL RING GEAR
(a) Using ATF and a heater, heat the front differential
ring gear to 90 to 110
C (194.0 to 230.0F).
NOTICE:
Do not overheat the ring gear to 110
C (230.0F)
or more.
(b) Clean the contract surface of the front differential
case.
(c) Align the matchmarks, and install the front
differential ring gear case quickly.
NOTICE:
• Check the position and number of the
grooves on each end face of the differential
ring gear.
• Do not install the bolts while the ring gear is
hot.
(d) Tighten the 14 bolts.
Torque: 95 N*m (969 kgf*cm, 70 ft.*lbf)
NOTICE:
Tighten the bolts a little at a time in diagonal
order.

DEFINITION OF TERMS
Te r m D e f i n i t i o n
Monitor description Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCs Diagnostic code.
Typical enabling conditionPreconditions that allow the ECM to detect malfunctions.
With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the
malfunction threshold(s).
Sequence of operationThe priority order that is applied to monitoring, if multiple sensors and components are used to detect the
malfunction.
While another sensor is being monitored, the next sensor or component will not be monitored.
Required sensor/Components The sensors and components that are used by the ECM to detect malfunctions.
Frequency of operationThe number of times that the ECM checks for malfunctions per driving cycle.
"Once per driving cycle" means that the ECM detects malfunction only 1 time during a single driving cycle.
"Continuous" means that the ECM detects a malfunction every time the enabling condition is met.
DurationThe minimum time that the ECM must sense a continuous deviation in the monitored value(s) before
setting a DTC. This timing begins after the "typical enabling conditions" are met.
Malfunction thresholds Beyond this value, the ECM will conclude that there is a malfunction and set a DTC.
MIL operationMIL illumination timing after a defect is detected.
"Immediate" means that the ECM illuminates the MIL the instant the ECM determines that there is a
malfunction.
"2 driving cycle" means that the ECM illuminates the MIL if the same malfunction is detected again in the
2nd driving cycle.
Component operating rangeNormal operation range of sensors and solenoids under normal driving conditions.
Use these ranges as a reference.
They cannot be used to judge if a sensor or solenoid is defective or not.

AX
INSPECTION
1. INSPECT UNDERDRIVE PACK CLEARANCE
(a) Install the underdrive clutch to the transaxle case.
NOTICE:
Be careful not to damage the oil seal rings.
(b) Install a dial indicator as shown in the illustration.
(c) Measure the underdrive clutch pack clearance while
applying and releasing compressed air (392 kPa,
4.0 kgf/cm
2, 57 psi).
Standard pack clearance:
1.51 to 1.90 mm (0.0594 to 0.0748 in.)
If the pack clearance is not as specified, inspect the
discs, plates and flange.
2. INSPECT NO. 1 UNDERDRIVE CLUTCH DISC
(a) Check to see if the sliding surface of the disc, plate
and flange are worn or burnt. If necessary, replace
them.
HINT:
• If the lining of the disc is peeling off or discolored,
or even if a part of the printed mark is defaced,
replace all discs.
• Before assembling new discs, soak them in ATF
for at least 15 minutes.
3. INSPECT UNDERDRIVE CLUTCH RETURN SPRING
SUB-ASSEMBLY
(a) Using a vernier caliper, measure the free length of
