DIFFERENTIAL BEARING
ADJUSTMENT
True bearing turning torque readings can only be obtained
with the gear train removed from the case.
(1) Remove bearing cup and existing shim from clutc h
housing case.
(2) Press in new bearing cup into bell housing case (or use
a cup that has been ground down on the outer edge
for ease of measurement).
(3) Press in new bearing cup into gear case side.
(4) Lubricate differential bearings with SAE
engine
oil. Install differential assembly in transaxle gear case.
Install clutch bell housing over gear case.

(5) Position transaxle with bell housing facing dow n on work-
bench with C-clamps. Position dial indicator.
(6) Apply a medium load to differential with
and
a T-Handle, in the downward direction. Roll differe ntial
assembly back and forth many times. This will settl e the
bearings. Zero dial indicator. To obtain end play r eadings,
apply a medium load in the upward direction while r olling
differential assembly back and forth. Record end play.
(7) The shim required for proper bearing preload is total of
end play and (constant) preload of 0.18 mm
in.).
(8) Remove case bolts. Remove clutch bell housing d ifferen-
tial bearing cup. Install shim(s) selected in step (7). Then
press the bearing cup into clutch bell housing.
(9) Install and torque case bolts to 26 Nm (19
(lO)Using and an inch-pound torque wrench,
check turning torque of the differential assembly c lockwise
and counterclockwise. The turning torque should be 68
to 136 Ncm (6 to 12
If the turning torque is too
high, install a 0.5 mm in.) thinner shim. If the turning
torque is too low, install a 0.5 mm in.) thicker shim.
(11) Recheck turning torque. Repeat Step (10) until the proper
turning torque is obtained.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL EQUIPPED VEHICLES
WARNING! (1) Improper service or maintenance of any componen t of the
or any component, can lead to personal
injuryordeath inadvertent the inoperative).
(2) Service or maintenance of any component or SRS-related component must be perform ed only at an authorized
MITSUBISHI dealer.
(3)MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP Supplemental Re-
straint System (SRS) and GROUP 00 -Maintenance Serv ice before beginning any service or maintenance of any com-
ponent of the
or any component.
NOTEThe SRS includes the following components: SRS-ECU, SRS warning light, air bag module, clockspring and inte rconnecting wiring.Other SRS-related components (that may have to be removed/installed in connection with SRS service or maintenance) are indi-cated in the table of contents by an asterisk

NOTE
Other diagnostic trouble codes also output as the s ame code numbers as when using the scan tool.
HOW TO ERASE THE DIAGNOSTIC TROUBLE CODES
When using the scan tool
1.Turn the ignition switch to OFF and then back to ON again.
2. Erase the diagnostic trouble codes.
3.Check to be sure that no diagnostic trouble codes e xist.
When using a voltmeter (1) Turn the ignition switch to the OFF position.
(2) After disconnecting the battery cable from the battery
terminal for seconds or more, reconnect the cable.
(3) Turn the ignition switch to the ON position, re ad the diagnostic trouble codes and check that a no rmal code
is output.

Code No. Throttle position sensor system Probable cause
[Comment] of the throttle If the TPS output becomes 4.6 or more at idle, TPS output is excessive, and of connector
trouble code No. 11 is output. If the TPS output be comes 0.2 or less at times other than l of idling, TPS output is insufficient and diagnostic t rouble code No. 12 is output. If the TPS output
and the target value inside the TCM do not match ev en after compensation is carried out while
the engine is idling, the TPS sensor is defective and diagnostic trouble code No. 13 is output.
If the TPS voltage becomes 0.2 or less or 1.2 or more while the engine is idling, the
TPS adjustment is defective and diagnostic trouble code No. 14 is output.

[Comment] If the oil temperature sensor output is 4.4 or higher (oil temperature does not increase) evenafter driving for 10 minutes or more, there is an o pen circuit in the oil temperature sensor
and diagnostic trouble code No. 15 is output.
When the oil temperature sensor output is 0.2 or less (for 1 second or more), it is judgedthat there is a short-circuit in the oil temperatur e sensor and diagnostic trouble code No. 16is output.
