Downloaded from www.Manualslib.com manuals search engine •Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start engine and warm it to normal operating temperature, then select Dposition.
• Drive the vehicle in 1st, 2nd, 3rd and 4th gears.
• 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 :
Checking the automatic transaxle fluid quality and fluid level is the most basic check of the automatic transaxle. The
fluid check is also an important inspection to determine if the transaxle will need to be disassembled.
CAUTION:
The burnt scent of ATF fluid indicates that the transaxle fluid is contaminated. The tiny particles in
the fluid pan indicate that the transaxle is worn out and it will be necessary to overhaul the trans-
axle.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK FLUID QUALITY AND FLUID LEVEL AND DTC
• Drive the vehicle, until the ATF reaches operating temperature (70° - 80°C).
• Park the vehicle on level ground.
• Shift the gear selector lever to all gear positions once, then shift to gear “N”.
• Clean and check the outside of the dipstick and remove the dipstick to check the fluid level.
• With the scan tool, select view DTC and data stream for A/T.
• Start the engine.
• Monitor the value of the gear position as indicated in the following table while driving:

• 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.

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

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.
