Diagnostic Procedure

Step

Inspection

Action

1

VERIFY VEHICLE COLLISION

•  Explain to the customer that the vehicle was hit.

•  Has the vehicle been hit?

Yes

•  Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)

No

Go to the next step.

2

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

•  Reconnect all the disconnected connectors.

•  Reconnect the disconnected negative battery cable.
(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].)

(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].)

•  Clear the DTC for the SAS control module using the M-MDS.
(See CLEARING DTC.)

•  Perform the DTC inspection for the SAS control module using the M-MDS.
(See DTC INSPECTION.)

•  Are the same DTCs displayed?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the SAS control module, then go to the next step.
(See SAS CONTROL MODULE REMOVAL/INSTALLATION.)

No

Go to the next step.

3

VERIFY IF OTHER DTCs DISPLAYED

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning part according to the applicable DTC troubleshooting.

(See DTC TABLE.)

No

DTC troubleshooting completed.
