2009 CHERY TIGGO check engine

Downloaded from www.Manualslib.com manuals search engine 7.CHECK DTC
• 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
>>The system is now operating properly.

>>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 6.
No
>>Go to the next step.

• Turn the ignition switch on.
• Check power supply between shift solenoid valve 1
(SSV1) E-037, terminal B11 and ground in the A/T
assembly connector E-037.
• Voltage should be more than 12 V.
• Or using the appropriate diagnostic test tool and a digital multimeter perform the following:
• Check the EVS1 solenoid supply voltage between TCM pin 1 and TCM pin 10 when activating the EVS1 sole-
noid and deactivating the EVS1 solenoid.
• Check the shift solenoid control signal. Check the voltage of the shift solenoid in each shift position.
• Check the voltage of the EVS1 solenoid supply circuit between the transaxle assembly electrical connector pin
B3 and pin B11.
