VERIFY EPS CONTROL MODULE DTC

•  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, go to the next step.

No

Go to Step5.

3

VERIFY INSTRUMENT CLUSTER DTC
