Description
The transaxle gear train is comprised of two rows of planetary gear set, one one-way clutch and five actuators (three
composite disc clutches and two composite disc brakes.
It is controlled with adaptive electronic controls and monitors. The hydraulic system of the transaxle consists of the
transaxle fluid, fluid passages, hydraulic valves, fluid pump, and various line pressure control components.
The Transaxle Control Module (TCM) is the heart of the electronic control system and relies on information from
various direct and indirect inputs (sensors, switches, etc.) to determine driver demand and vehicle operating condi-
tions. With this information, the ECM/TCM can calculate and perform timely and quality shifts through various output
or control devices.
The TCM also performs certain self-diagnostic functions and provides comprehensive information (sensor data,
DTCs, etc.) which is helpful in proper diagnosis and repair. This information can be viewed with the X-431 scan tool.

•Self-diagnosis detection logic.
DTC NO. DTC DEFINITION DTC DETECTION
CONDITION DTC SET
CONDITION POSSIBLE CAUSES
22 Input speed sensor Vehicle is driving •
The Transaxle
Control Module
(TCM) will set this
DTC when the TCM
didn’t received pulse
signal from the input
shaft speed sensor
for above 1 seconds
when the vehicle is
driving for 30 km/h
at 3 or 4 gear.
• If the DTC was
set for 4 times, then
the A/T will be
locked in 3rd gear
(D gear) or shifted
to low gear when in
sports mode. •
Input shaft speed
sensor
• The retainer of
deceleration clutch
• Harness or
connectors (The
sensor circuit is open
or shorted)
• TCM
DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start the engine and warm it to normal operating temperature.
• Drive the vehicle up to 10 km/h or more.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 08 Transaxle & Transfer Case for more information).
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.

• Connect the TCM and sensor electrical connector.
• Start the vehicle and perform the following:
Engine: 2000 RPM
Vehicle: 50 km/h
Gear: 3
• Check sensor signal between sensor terminal 2 and ground in the sensor electrical connector E-088 with the
X-431 or oscilloscope.
• Make sure the wave shape is normal and signal voltage is fluctuating from0-5V.
Is the check result normal?
Ye s>>Go to step 9.
No
>>Go to the next step.
7.CHECK INPUT SHAFT SPEED SENSOR
• Perform the following:
Loosen the bolt of the sensor.
Remove the sensor.
Visually inspect the sensor for missing or chipped teeth.
Is the check result normal?
Ye s>>Replace the input speed sensor.
Monitor the input speed sensor signal on the X-431 or oscilloscope.
If the input speed sensor signals were normal, the system is OK.
If the input speed sensor signals were still irregular or missing, go to step 8.
No
>>Replace input speed sensor.
8.CHECK THE RETAINER OF DECELERATION CLUTCH
• Disassemble and inspect the A/T and replace the retainer for the deceleration clutch.
• Check for a chipped and damaged signal retainer for the deceleration clutch.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace the retainer for the deceleration clutch.
Monitor the input speed sensor signal on the X-431 or oscilloscope.
If the signal pulse is not normal, repair the noise interference.
9.CHECK DTC
• With the X-431 scan tool, read TCM DTCs.
• Refer to DTC Confirmation Procedure.
Is the check result normal?
Ye s>>The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
No
>>Replace the TCM.

Transfer Case).
No
>>Go to the next step.
2.ACTUATE TEST
• With X-431, perform the solenoid actuate test.
• The solenoid should be heard.
Is the check result normal?
Ye s>>Go to step 7.
No
>>Go to the next step.
3.CHECK REVERSE/LOW GEAR ELECTRO-MAGNETIC VALVE
• Turn the ignition switch off.
• Disconnect A/T assembly connector.
