TRANSAXLE ASSEMBLY
 When using the drive plate location guide (commercial service tool:
31197CA000) (A), set it to the stud bolts which is used to install it
to the torque converter.
 When not using drive plate location guide, rotate torque converter
so that the stud bolt (B) for mounting the drive plate location guide
of torque converter aligns with the mounting position of service
hole.
 Rotate crankshaft so that the hole (A) for inserting drive plate loca-
tion guide of drive plate aligns with the service hole (B).
NOTE:
When not using drive plate location guide, insert stud bolt of torque
converter into the hole (C) of drive plate, aligning the drive plate
hole position and torque converter.
CAUTION:
Be careful not to strike the drive plate when installing the
torque converter stud bolt.
 Align the position of tightening nuts ( ) for drive plate with those
of the torque converter, and temporarily tighten the nuts. Then,
tighten the bolts to the specified torque.
CAUTION:
 When turning crankshaft, turn it clockwise as viewed from the
front of the engine.
 When tightening the nuts for the torque converter after fixing
the crankshaft pulley bolts, confirm the tightening torque of
the crankshaft pulley mounting bolts. Refer to EM-79,
"Exploded View".
 Rotate crankshaft several turns and check that transaxle rotates freely without binding after con-
verter is installed to drive plate.
 Never reuse O-ring.
 Apply petroleum jelly to O-ring.

DIAGNOSIS AND REPAIR WORK FLOW
BASIC INSPECTION
DIAGNOSIS AND REPAIR WORK FLOW
Work FlowINFOID:0000000003806344
INTRODUCTION
The TCM receives signals from the vehicle speed sensor and PNP switch. Then it provides shift control or
lock-up control via CVT solenoid valves.
The TCM also communicates with the ECM by means of signals
sent from sensing elements used with the OBD-related parts of the
CVT system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose a malfunction that occurs inter-
mittently rather than continuously. Most intermittent malfunctions are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace-
ment of good parts.
A visual check only may not find the cause of the malfunctions. A
road test with CONSULT-III (or GST) or a circuit tester connected
should be performed. Follow the “DETAILED FLOW”.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such malfunctions, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A “Diagnostic Work Sheet” as
shown on the example (Refer to TM-177
) should be used.
Start your diagnosis by looking for “conventional” malfunctions first.
This will help troubleshoot driveability malfunctions on an electroni-
cally controlled engine vehicle.
Also check related Service Bulletins.
