Chery Tiggo. Manual — part 254
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.

3.
CHECK SHIFT SOLENOID VALVE 3 (SSV3) RESISTANCE
• Check SSV3 resistance as follows:

VALVE 1 (SSV1)
B11 - B3
VALVE 2 (SSV2)
B8 - B3

VALVE 6 (SSV6)
B2 - B3
RESISTANCE (23°C)
38 - 42 (
⍀)
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 3 (SSV3) POWER SUPPLY
• Turn the ignition switch on.
• Check power supply between SSV3 E-037 terminal
B10 and ground in the A/T assembly connector
E-037.
• Battery voltage should exist.
• Or using the appropriate diagnostic test tool and a digital multimeter perform the following:
• Check the EVS3 solenoid supply voltage between TCM pin 1 and TCM pin 7 when activating the EVS3 sole-
noid and deactivating the EVS3 solenoid.
• Check the shift solenoid control signal. Check the voltage of the shift solenoid in each shift position.
• Check the voltage of the EVS3 solenoid supply circuit between the transaxle assembly electrical connector pin
B3 and pin B10.

CHECK SHIFT SOLENOID VALVE 3 (SSV3) 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.
