Disassembly and AssemblyNBS003IR
DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separate front suspension member, transmission and front final drive from engine. Refer to EM-243, "
ENGINE ASSEMBLY" .
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use widely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.

Holding ring gear with ring gear stopper (SST).

Loosen mounting bolts diagonally order.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand. CAUTION:
Use engine stand that has a load capacity [approximately 240 kg (529 lb) or more] large enough for
supporting the engine weight.

If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning stand.
13. Piston pin 14. Connecting rod bearing 15. Connecting rod bearing cap
16. Block heater protector 17. Connector cap 18. Cylinder block heater
19. Gasket 20. Main bearing cap 21. Thrust bearing
22. Main bearing 23. Rear plate 24. Crankshaft
25. Pilot converter 26. Drive plate 27. Thrust bearing
28. Side bolt 29. Reinforcement plate 30. Crankshaft position sensor (POS)
31. O-ring 32. Rear oil seal 33. Rear oil seal retainer

POWER WINDOW SERIAL LINK
Power window main switch, front power window switch (passenger side), and BCM transmit and receive the
signal by power window serial link.
The under mentioned signal is transmitted from BCM to power window main switch and front power window
switch (passenger side)

Keyless power window down signal.
The under mentioned signal is transmitted from power window main switch to front power window switch (pas-
senger side)

Front passenger side door window operation signal.

Power window control by key cylinder switch signal.

Power window lock signal.

Retained power operation signal.
POWER WINDOW LOCK
The power window lock is designed to lock operation of all windows except for driver side door window.
When the lock position, ground of the rear power window switches in the power window main switch is discon-
nected. The power window lock signal is transmitted to front power window switch (passenger side) by power
window serial link. This prevents the power window motors from operating.
RETAINED POWER OPERATION
When the ignition switch is turned to the OFF position from ON or START position.
Power is supplied for 45 seconds

through BCM terminal 53

to power window main switch terminal 10

to rear power window switch (LH and RH) terminals 1.
When power and ground are supplied, the BCM continues to be energized, and the power window can be
operated.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to GW-29, "
CONSULT-II Function (BCM)" .
ANTI-PINCH SYSTEM
Power window main switch and front power window switch (passenger side) monitors the power window motor
operation and the power window position (full closed or other) for driver side and passenger side power win-
dow by the signals from encoder and limit switch in front power window motor (driver side and passenger
side).
When power window main switch detects interruption during the following close operation,

automatic close operation when ignition switch is in the “ON” position

automatic close operation during retained power operation

manual close operation during retained power operation
power window main switch or front power window switch (passenger side) controls each power window motor
for open and the power window will be lowered about 150 mm (5.91 in).
POWER WINDOW CONTROL BY THE KEY CYLINDER SWITCH
When ignition key switch is OFF, front power window can be opened or closed by turning the key cylinder
switch UNLOCK / LOCK position more than 1.5 second over condition.

Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.

Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.
The power window DOWN stops when the following operations are carried out.

While performing open / close the window, power window is stopped at the position as the door key cylin-
der is placed on NEUTRAL.

When the ignition switch is turned ON while the power window DOWN is operated.

ACTIVE TEST
WORK SUPPORT
DATE MONITOR
BCM diagnostic test item Check item diagnostic test mode Content RETAINED PWR Work support Changes setting of each function.
Data monitor Displays the input data of BCM in real time.
Active test Gives a drive signal to a load to check the operation.
Test Item Description
RETAINED PWR This test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in “OFF” position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-II screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-II might be stuck if
“RETAINED PWR” is turned to “ON” or “OFF” on CONSULT-II screen when ignition switch is OFF.
Work item Description
RETAINED PWR Rap signal’s power supply period can be changed by mode setting. Selects rap signal’s power
supply period between three steps

MODE1 (45 sec.) / MODE2 (OFF) / MODE 3 (2 min.).
Work item Description
