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.
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start the engine and warm it to normal operating temperature.
• Try to operate the shifter selector.
• 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).
• If using the appropriate diagnostic test tool, you can diagnose the TCM harness while the TCM is still con-
nected.
• Using the appropriate diagnostic test tool in this way will help prevent electrical connector terminal damage.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK SHIFT LOCK SOLENOID VALVE 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 and DTC not present?
Ye s>>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?
Ye s>>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?
Ye s>>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 7.
If the solenoid can’t be heard, go to the next step.
No
