Subaru Crosstrek Service Manual: Dtc c2511 torque sensor main

Trouble symptom:

• The steering wheel operation feels heavy.

• STEERING warning light illuminates.

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 C2511 TORQUE SENSOR MAIN">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 connectors (B450, B451).

3) Using a tester and test harness, check the internal resistance of the harness terminals.

Repair or replace the harness.

3.CHECK POWER STEERING CONTROL MODULE.

1) Connect the connector (B450) to the power steering control module.

2) Turn the ignition switch to ON.

3) Short the circuit between connector (B451) terminals.

No. 4 — No. 3:

No. 4 — No. 5:

4) Using the Subaru Select Monitor, check the voltages of «Torque sensor main output» and «Torque sensor sub output».

Are the voltages of «Torque sensor main output» and «Torque sensor sub output» before you short the circuit 0±0.1 V?
Are the voltages of «Torque sensor main output» and «Torque sensor sub output» after you short the circuit 3±0.1 V?
