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.
• 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.
• 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).
DIAGNOSIS & TESTING

08–51Chery Automobile Co., Ltd.

Downloaded from www.Manualslib.com manuals search engine 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 and it will be necessary to overhaul the transaxle.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK FLUID QUALITY, FLUID LEVEL AND DTC
• Drive the vehicle until the TFT reaches working temperature (70° - 80°C).
• Park the vehicle on level ground.
• Shift the gear selector lever to all gear positions once, stay in one gear about 5 seconds, then shift to gear
“N”.
• Clean and check the outside of 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:

• Preheat the transaxle fluid to 80° - 100°C.
• Lift the vehicle until the wheels can rotate freely.
• Connect the special fluid pressure gage onto the
fluid pressure measurement port as (3).

• In accordance with the shown status of standard fluid pressure measurement table, measure the fluid pressure
of measurement port. The measurement of 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.

3.CHECK VALVE BODY ASSEMBLY AND FLUID PUMP AND PIPELINE
• Turn the ignition switch off.
• Remove and disassemble the DP0 Automatic Transaxle Assembly (See Automatic Transaxle Removal & Instal-
lation 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 the damaged components as needed.

• 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: Low speed clutch piston should be active and maintain pressure when
compressed air is applied to the fluid hole.

• Assemble all the disassembled components.
• Install the Automatic Transaxle Assembly (See Automatic Transaxle Removal & Installation in Section 08 Trans-
axle & Transfer Case).
• Fill with new ATF.
• Fill the ATF from the refilling tube.
• Refit the hose connector disassembled in step 1 and refit the dipstick (clean the dipstick before refit).
• Shift the gear selector lever to each gear position and then shift to gear “N”.
• Drive the vehicle until the ATF reached working temperature (70° - 80°C) and re-check the fluid level. The fluid
level must be within the HOT range of dipstick.
• Refit the checking dipstick of transaxle.
• With the X-431 scan tool, read TCM DTCs.
• Refer to DTC Confirmation Procedure.
Is DTC P0730 still present?
Ye s>>Replace the TCM.
No
