Diagnostic Procedure

Step

Inspection

Action
1
INSPECT TORQUE SENSOR
•  Using the M-MDS, perform the PID inspection for torque sensor.
?  STR_TRQ_S_M
?  STR_TRQ_S_S
•  Do the PIDs indicate as followings?
?  Steered left: Changes to 0 Nm—positive
?  Steered right: Changes to 0 Nm—negative
Yes
Go to the next step.
No
Replace the steering column, then go to the next step.
(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.)
2
VERIFY DTC TROUBLESHOOTING COMPLETED
•  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 DTC present?
Yes
Repeat the inspection from Step1.
If the malfunction recurs, replace the EPS control module, then go to the next step.
(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.)
No
Go to the next step.
3
VERIFY NO DTC IS PRESENT
•  Are any DTCs present?
Yes
Go to applicable DTC inspection.
(See DTC TABLE [ELECTRIC POWER STEERING (EPS)].)
No
DTC troubleshooting completed.
