Diagnostic Procedure

Step

Inspection

Action

1

PERFORM SAS CONTROL MODULE DTC INSPECTION

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

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

•  Is the DTC B1193:00 displayed?

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

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

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

•  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 [SAS CONTROL MODULE].)

No

DTC troubleshooting completed.
