Chery Tiggo. Manual — part 263
• #: Operating solenoid
Is the check result normal and DTC not present?
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.
• Watch, listen and monitor the shift lock solenoid condition and verify the shift lock solenoid works correctly and
the solenoid should be heard when actuate shift lock solenoid valve.
Is the check result normal?
Yes
>>
Go to step 7.
No
>>
Go to the next step.
3.
CHECK SHIFT LOCK SOLENOID VALVE RESISTANCE
• Turn the ignition switch off.
• Disconnect shift lock solenoid valve connector C-027.
• Check shift lock solenoid valve resistance as shown in the following table:
SHIFT LOCK SOLENOID VALVE RESISTANCE
BASED ON TRANSAXLE TEMPERATURE
Temperature
Resistance
23°C
36 - 44
⍀
Is the check result normal?
Yes
>>
Replace the shift lock solenoid valve with a known good one.
With X-431, perform the solenoid actuate test.
− If the solenoid can be heard, go to step 7.
− If the solenoid can’t be heard, go to the next step.
No
>>
Replace the shift lock solenoid for a mechanical problem.
DIAGNOSIS & TESTING
4.
CHECK SHIFT LOCK SOLENOID VALVE POWER SUPPLY
• Turn ignition switch on.
• Check the shift lock solenoid valve power supply.
• Battery voltage should exist.
Is the check result normal?
Yes
>>
Go to the next step.
No
>>
Repair or replace open circuit or short to
ground in harness or connectors.
5.
CHECK SHIFT LOCK SOLENOID VALVE CONTROL CIRCUIT
• Turn the ignition switch on.
• Check the shift lock solenoid control signal voltage of the shift lock solenoid when pressing the brake pedal.
• Check power supply between shift lock solenoid valve terminal 4 and 5 in the shifter selector connector C-027.

• Check the harness for short to power supply.
Is the check result normal?
Yes
>>
Go to the next step.
No
>>
Repair or replace the circuit for short to power supply in harness or connectors.
7.
CHECK DTC
• With the X-431 scan tool, read TCM DTCs.
• Refer to ⬙DTC Confirmation Procedure⬙.
Is DTC P1928 present?
Yes
>>
Replace the TCM.
No
>>
The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
