DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• After connection, press POWER key to start X-431.
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start engine then select Dposition.
• Drive the vehicle.
• 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.
Diagnostic Procedure
1.CHECK BRAKE PEDAL POSITION SWITCH SIGNAL
• With the scan tool, select view DTC and data stream for A/T.
• Start vehicle and read out the value of STOP LAMP SWITCH.

• In accordance with the shown status of standard fluid pressure measurement table, measure the fluid pressure
of each measurement port. The measurement of each port should be within the standard range.
• If some measurement values is beyond the standard range, please refer to the fluid pressure measurement and
diagnosis table for causes.
Is the check result normal?
Ye s>>Go to step 5 for disc or plate abrasion.
No
>>Go to the next step.
3.CHECK VALVE BODY ASSEMBLY AND FLUID PUMP AND PIPELINE
• Turn the ignition switch off.
• Disassemble and repair F4A4 automatic transaxle assembly (See Automatic Transaxle Removal & Installation in
Section 08 Transaxle & Transfer Case).
• Check valve body and fluid pump and pipeline.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace damaged components and low speed clutch and reverse/low brake clutch for low pressure
burned.
4.COMPRESSED AIR TEST
• Check low speed clutch system: Low speed clutch piston should be active and maintain pressure when com-
pressed air is applied to the fluid hole.
• Check reverse/low brake clutch system: Reverse/low brake clutch piston should be active and maintain pressure
when compressed air is applied to the fluid hole.
Is the check result normal?
Ye s>>Go to the next step for disc or plate abrasion.
No
>>Replace damaged components and low speed clutch and reverse/low brake clutch for low pressure
burned.

Snap ring
Clutch reaction disc
D-Ring
Spring retainer
Low speed clutch piston
Low speed clutch drum
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace the damaged components.
6.CHECK REVERSE/LOW BRAKE SYSTEM
• Check reverse/low brake system:
Check reverse/low brake plate
Check reverse/low brake disc
Central support
Snap ring
Clutch reaction disc
Spring retainer
Reverse/low brake piston
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace the damaged components.
7.CHECK DTC
• Assemble all disassembled components.
• Install the transaxle assembly (See Automatic Transaxle Removal & Installation in Section 08 Transaxle &
Transfer Case).
• Fill the transaxle with new ATF:
Fill the ATF from the fill tube.
Reinstall the hose connector disassembled in step 1 and reinstall the dipstick (clean the dipstick before
installing).
Shift the gear selector lever to each gear position and then shift to gear “N”.
Drive the vehicle until the ATF reaches operating temperature (70° - 80°C) and re-check the fluid level. The fluid level must be within the HOT range of dipstick.
Reinstall the dipstick into the transaxle.
With the X-431 scan tool, read TCM DTCs.
Refer to DTC Confirmation Procedure.
Is DTC 41 still present?
Ye s>>Replace the TCM.
No
>>The system is now operating properly.
