SYMPTOM:
Unbalance steering wheel turning force and return between right and left, while driving.
DIAGNOSTIC PROCEDURE
1.CHECK EPS WARNING LAMP
Confirm EPS warning lamp during engine running.
Does EPS warning lamp turn OFF?
YES >> GO TO 2.
NO >> Go to STC-31, "
Diagnosis Procedure".
2.CHECK WHEEL ALIGNMENT
Check wheel alignment. Refer to FSU-6, "
Wheel Alignment Inspection".
OK or NG
OK >> GO TO 3.
NG >> Adjust wheel alignment. Refer to FSU-6, "
Wheel Alignment Inspection".
3.CHECK EPS CONTROL UNIT
Check EPS control unit input/output signal. Refer to STC-22, "
EPS Control Unit Input/Output Signal Reference
Va l u e".
OK or NG
OK >> GO TO 4.
NG >> Check EPS control unit pin terminals for damage or loose connection with harness connector. If
any items are damaged, repair or replace damaged parts.
4.SYMPTOM CHECK
Check again.
OK or NG
OK >>INSPECTION END
NG >> Check the steering wheel turning force because there may be mechanical malfunction. Refer to
ST-6, "
On-Vehicle Inspection and Service".

 Check if the connection of steering column assembly and steering gear assembly is proper (there is
not looseness of mounting bolts, damage of rods, boots or sealants, and leakage of grease, etc).
 Check if the wheel alignment is adjusted properly.
 Check if there is any damage or modification to suspension or body resulting in increased weight or
altered ground clearance.
 Check if installation conditions of each link and suspension are proper.
 Check if the battery voltage is proper
 Check connection conditions of each connector are proper.
 Before connecting or disconnecting the EPS control unit har-
ness connector, turn ignition switch “OFF” and disconnect
battery ground cable. Because battery voltage is applied to
EPS control unit even if ignition switch is turned “OFF”.
 When connecting or disconnecting pin connectors into or
from EPS control unit, take care not to damage pin terminals
(bend or break).
When connecting pin connectors, make sure that there are no
bends or breaks on EPS control unit pin terminal.
 Before replacing EPS control unit, perform EPS control unit
input/output signal inspection and make sure whether EPS
control unit functions properly or not. Refer to STC-22, "
EPS
Control Unit Input/Output Signal Reference Value".

< REMOVAL AND INSTALLATION >[TYPE 1 (4AT: RE4F03B)]
TRANSAXLE ASSEMBLY
When installing the torque converter to the transaxle measure dis-
tance A.
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. Refer to TM-210, "
Exploded View".
 When turning crankshaft, turn it clockwise as viewed from the front of the engine.
 When tightening the bolts 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-50, "
Removal and Installa-
tion".
 After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.
 When installing the transaxle to the engine, align the matching mark on the drive plate with the matching
mark on the torque converter.
 When securing the transaxle assembly to the engine, attach the
bolts in accordance with the following standard.
(A): A/T to engine
(B): Engine to A/T
 Align the positions for the bolts on drive plate with those of the
torque converter, and temporarily tighten bolts. Then, tighten bolts
to the specified torque.
 After completing installation, check for A/T fluid leakage, A/T fluid
level and A/T positions. Refer to TM-171, "
Checking A/T Fluid" and
TM-204, "
Checking of A/T Position". Dimension A: 16.2 mm (0.638 in) or more
