Diagnostic Procedure

Step	Inspection		Action
1	INSPECT TORQUE SENSOR USING M-MDS •  Connect the M-MDS to the DLC-2. •  Switch the ignition to ON (engine OFF). •  Access “SS_TRQ1” and “SS_TRQ2” PIDs. (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.) •  Verify that the data monitor value changes when the steering wheel is turned. ―  Left: 0—positive ―  Right: 0— negative •  Do the torque sensor signal values change in the same way?	Yes	Malfunction may be temporary. Go to step 6.
		No	Go to the next step.
2	INSPECT WHETHER MALFUNCTION IS CAUSED BY POOR CONNECTION OF EPS CM OR PIN DEFORMATION •  Switch the ignition to off. •  Inspect connection of the EPS control module and wiring harness. •  Disconnect the EPS control module connector. •  Inspect whether malfunction is caused by bent or poorly connected EPS control module connector pin. •   Are the connector connection, connector pins, and wiring harness normal?	Yes	Go to the next step.
		No	Repair or replace the faulty connector wiring harness, then go to Step 6.
3	IINSPECT TORQUE SENSOR CIRCUIT FOR OPEN CIRCUIT •  Inspect for continuity between the EPS control module terminals and torque sensor terminals. ―  EPS control module terminal 3A—torque sensor terminal C ―  EPS control module terminal 3C—torque sensor terminal B ―  EPS control module terminal 3D—torque sensor terminal A •  Is there continuity?	Yes	Go to the next step.
		No	Repair or replace the wiring harness for open circuit between the EPS control module and torque sensor, then go to Step 6.
4	INSPECT TORQUE SENSOR CIRCUIT FOR SHORT TO POWER •  Measure the voltage between the torque sensor terminals and ground. ―  Torque sensor terminal A—ground ―  Torque sensor terminal B—ground ―  Torque sensor terminal C—ground •  Is there any B+?	Yes	Repair or replace the wiring harness for short to power between the EPS control module and torque sensor, then go to Step 6.
		No	Go to the next step.
5	INSPECT TORQUE SENSOR CIRCUIT FOR SHORT TO GROUND •  Inspect for continuity between the torque sensor terminals and ground. ―  Torque sensor terminal A—ground ―  Torque sensor terminal B—ground ―  Torque sensor terminal C—ground •  Is there continuity?	Yes	Repair or replace the wiring harness for short to ground between the EPS control module and torque sensor, then go to the next step.
		No	Replace the steering gear and linkage (torque sensor), then go to the next step. (See STEERING GEAR AND LINKAGE REMOVAL/INSTALLATION [L.H.D.].) (See STEERING GEAR AND LINKAGE REMOVAL/INSTALLATION [R.H.D.].)
6	VERIFY THAT SAME DTC IS NOT PRESENT •  Make sure to reconnect all disconnected connectors. •  Clear the DTC from the memory. (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.) •  Is the same DTC present? (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the EPS control module. (See EPS CONTROL MODULE REMOVAL/INSTALLATION.)
		No	Go to the next step.
7	VERIFY THAT NO OTHER DTCs ARE PRESENT •  Are any other DTCs output? (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)	Yes	Go to the applicable DTC inspection. (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)
		No	DTC troubleshooting completed.
