Diagnostic Procedure

Step

Inspection

Action

1

RECORD THE CAR CONFIGURATION DATA

•  Switch the ignition off.

•  Switch the ignition ON (engine off or on), and maintain this condition for approx. 1 min.

•  Switch the ignition off, and maintain this condition for approx. 3 s.

•  Switch the ignition ON (engine off or on).

—

Go to the next step.

2

VERIFY THAT THE SAME DTC IS NOT PRESENT

•  Using the M-MDS, clear the DTC from the EPS control module.
(See CLEARING DTC [ELECTRIC POWER STEERING (EPS) CONTROL MODULE].)

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

•  Is the same Pending DTC present?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, go to the next step.

No

Go to Step 5.

3

INSPECT FOR INSTRUMENT CLUSTER MALFUNCTION

•  Switch the ignition OFF.

•  Using the M-MDS, perform the DTC inspection for the instrument cluster.
(See DTC INSPECTION [INSTRUMENT CLUSTER].)

•  Are any DTCs detected?

Yes

Go to applicable DTC inspection.

(See DTC TABLE [INSTRUMENT CLUSTER].)

After repairing the instrument cluster, perform the “INSTRUMENT CLUSTER CONFIGURATION”, then go to the next step.

(See INSTRUMENT CLUSTER CONFIGURATION (USING READ/WRITE FUNCTION).)

(See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)

No

Go to the next step.

4

VERIFY THAT THE SAME DTC IS NOT PRESENT

•  Using the M-MDS, clear the DTC from the EPS control module.
(See CLEARING DTC [ELECTRIC POWER STEERING (EPS) CONTROL MODULE].)

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

•  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.
(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.)

No

Go to the next step.

5

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.
