TCM terminals data are reference values, measured between each terminal and ground.
Diagnostic ProcedureUCS0063O
1. CHECK INPUT SIGNALS
With CONSULT-II
1. Start engine.
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “TRANSMISSION” with CONSULT-II.
3. Start vehicle and read out the value of “STM STEP”, “SMCOIL
A”, “SMCOIL B”, “SMCOIL C”, and “SMCOIL D”.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
2. CHECK HARNESS BETWEEN TCM AND STEP MOTOR
1. Turn ignition switch OFF.
2. Disconnect CVT unit connector and TCM connector.
3. Check continuity between TCM connector terminals and CVT
unit harness connector terminals.
4. If OK, check harness for short to ground and short to power.
5. If OK, check continuity between body ground and CVT assembly.
6. Reinstall any part removed.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.

TRANSAXLE ASSEMBLY
Revision: June 20062007 Versa
4. Remove the four drive plate to torque converter nuts.
NOTE:
Rotate the crankshaft clockwise as viewed from front of engine
for access to drive plate to torque converter nuts.
5. Put matching marks on the drive plate and torque converter alignment stud.
CAUTION:
For matching marks, use paint. Never damage the drive plate or torque converter.
6. Remove the transaxle to engine and engine to transaxle bolts.
7. Separate the transaxle from the engine.
8. If necessary, remove the following from the transaxle:

CVT fluid charging pipe

Engine mounting bracket (LH)

Fluid cooler tubes

Air breather hose

Any necessary brackets
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:

When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.

Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.

Do not reuse O-rings and copper washers.

When turning crankshaft, turn it clockwise as viewed from the front of the engine.

When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be
sure to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-37, "
TIMING
CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.

When installing the torque converter to the transaxle measure
distance A.

PrecautionUBS00QB5

Always use a 12 volt battery as power source.

Do not attempt to disconnect battery cables while engine is
running.

Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative
battery cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned OFF.

Before removing parts, turn ignition switch OFF and then
disconnect negative battery cable.

Do not disassemble ECM.

If battery cable is disconnected, the memory will return to
the initial ECM values.
The ECM will now start to self-control at its initial values.
Engine operation can vary slightly when the cable is dis-
connected. However, this is not an indication of a malfunc-
tion. Do not replace parts because of a slight variation.

If the battery is disconnected, the following emission-
related diagnostic information will be lost within 24 hours.
–Diagnostic trouble codes
–1st trip diagnostic trouble codes
–Freeze frame data
–1st trip freeze frame data
–System readiness test (SRT) codes
–Test values

When connecting ECM harness connector, fasten (B) it
securely with a lever (1) as far as it will go as shown in the
figure.
–ECM (2)
–Loosen (A)

When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.

Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to ICs.

Keep engine control system harness at least 10 cm (4 in)
away from adjacent harness, to prevent engine control sys-
tem malfunctions due to receiving external noise, degraded
operation of ICs, etc.

Keep engine control system parts and harness dry.
