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.

1.725 mm (0.0679 in.)
1.825 mm (0.0719 in.)
REASSEMBLY
1. INSTALL FRONT DIFFERENTIAL SIDE GEAR
(a) Coat the 2 front differential side gears, 2 side gear
thrust washers, 2 front differential pinions and 2
pinion thrust washers with ATF and install them to
the differential case.
2. INSTALL NO. 1 FRONT DIFFERENTIAL PINION
SHAFT
(a) Coat the No. 1 front differential pinion shaft with
ATF, and install it to the differential case.

3. INSTALL FRONT DIFFERENTIAL PINION SHAFT
STRAIGHT PIN
(a) Using a pin punch and a hammer, tap in the pinion
shaft straight pin.
(b) Using a chisel and a hammer, stake the differential
case.
NOTICE:
Stake it after adjusting the backlash.
4. INSTALL FRONT DIFFERENTIAL CASE REAR
TAPERED ROLLER BEARING
(a) Using SST and a press, press in the front differential
case rear tapered roller bearing to the differential
case.
