• Disconnect TCM connector.
• Check for harness continuity between the following terminals:
A/T ASSEMBLY
TERMINAL TCM
CONNECTOR TERMINAL CONTINUITY
51
4Yes
• Check the harness for short to power and short to ground.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace the circuit for an open or short to power or short to ground.

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.
DIAGNOSIS & TESTING

08–207Chery Automobile Co., Ltd.

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:

Is DTC 22 or 23 present?
Ye s>>If DTC 22 present, see diagnostic procedure for DTC 22 in 08 - Transaxle & Transfer Case.
If DTC 23 present, see diagnostic procedure for DTC 23 in 08 - Transaxle & Transfer Case.
No
