STEP | CHECK | YES | NO |
1.CHECK TORQUE SENSOR SIGNAL.
1) Display the current data of the power steering control module using the Subaru Select Monitor.
2) Check the voltage of «Torque sensor main output», «Torque sensor sub output», «Torque sensor reference voltage» and «Torque sensor power supply voltage».
Are the voltage of «Torque sensor main output» and «Torque sensor sub output» 2.5±0.1 V?
Is the voltage of «Torque sensor reference voltage» 3±0.1 V?
Is the voltage of «Torque sensor power supply voltage» 8±0.4 V?
Check for poor contact of the connector, and check the conditions again. If the condition recur, go to the next step. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C2514 TORQUE SENSOR POWER SUPPLY">Go to Step 2.
If it does not recur, complete the inspection.

2.CHECK HARNESS.
1) Turn the ignition switch to OFF.
2) Disconnect the connector (B451).
3) Using a tester and test harness, check the internal resistance of the harness terminals.
