Chery Tiggo. Manual — part 251
Diagnostic Procedure
1.
CHECK A/T SOLENOID SIGNAL
• 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 the check result normal?
Yes
>>
The condition that caused this DTC is intermittent (See Diagnostic Help in Section 08 Transaxle &
Transfer Case).
No
>>
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?
Yes
>>
Go to step 6.
No
>>
Go to the next step.

Is the check result normal?
Yes
>>
Replace the valve with a known good one.
With X-431, perform the solenoid actuate test.
− If the solenoid can be heard, Go to step 6.
− If the solenoid can’t be heard, Go to the next step.
No
>>
Replace the damaged solenoid valve.

4.
CHECK SHIFT SOLENOID VALVE 1 (SSV1) POWER SUPPLY
• 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.

CHECK SHIFT SOLENOID VALVE 1 (SSV1) CONTROL CIRCUIT
• Turn the ignition switch off.
• Disconnect TCM connector.
• Disconnect A/T assembly connector.
• Turn the ignition switch on.
• Check harness for short to power supply.
