Diagnostic Procedure

Step

Inspection

Action

1

INSPECT TORQUE SENSOR

•  Using the M-MDS, perform the PID inspection for torque sensor.
(See PID/DATA MONITOR INSPECTION [EPS CONTROL MODULE].)

―  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.
(See CLEARING DTC [EPS CONTROL MODULE].)

•  Using the M-MDS, perform the EPS control module DTC inspection.
(See DTC INSPECTION [EPS CONTROL MODULE].)

•  Is the same DTC present?

Yes

Repeat the inspection from Step1.

If the malfunction recurs, replace the steering column, 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 [EPS CONTROL MODULE].)

No

DTC troubleshooting completed.
