Diagnostic Procedure

Step

Inspection

Action
1
INSPECT TORQUE SENSOR USING M-MDS
•  Connect the M-MDS to the DLC-2.
•  Switch the ignition ON (engine off).
•  Access “STR_TRQ_S_M” and “STR_TRQ_S_S” PIDs.
•  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
Go to the next step.
No
Replace the steering column (torque sensor), then go to the next step.
(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.)
2
VERIFY THAT SAME DTC IS NOT PRESENT
•  Using the M-MDS, clear the DTC from the EPS control module.
•  Using the M-MDS, perform the EPS control module DTC inspection.
•  Is the same Pending DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the EPS control module, then go to the next step.
No
Go to the next step.
3
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any other DTCs output?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [ELECTRIC POWER STEERING (EPS) CONTROL MODULE].)
No
DTC troubleshooting completed.
