System malfunction location

• Seat weight sensor collision detection

Detection condition

WARNING:

• Detection conditions are for understanding the DTC outline before performing an inspection. Performing an inspection according to only the detection conditions may cause injury due to an operating error, or damage the system. When performing an inspection, always follow the inspection procedure.

• The pressure from the seat weight sensor is not within specification

Fail-safe

Not applicable

Possible cause

• Seat weight sensor calibration setting not implemented

• Seat weight sensor calibration setting invalid

• Seat weight sensor deformation or malfunction

• Foreign object under seat causing load on or deformation of the seat belt rail

• Front passenger-side seat under-bracket or frame deformed

• Weight acting on front passenger-side seat during calibration

• Front passenger-side seat part improperly installed at time of calibration

• Floor deformed where front passenger-side seat attached

• Seat weight sensor control module malfunction

• SAS control module malfunction

Step

Inspection

Action

1

• Visually inspect the passenger-side front seat for the following:

• Seat under-bracket deformation

• Seat frame deformation

• Seat weight sensor deformation

• Foreign objects stuck under seat

• Are any of the parts deformed or are any foreign objects stuck under the seat?

Yes

Replace any deformed parts or remove any foreign objects, then go to the next step.

No

Go to the next step.

2

• Visually inspect the installation parts of the front passenger-side seat for the following:

• Abnormal floor deformation

• Installation hole of front passenger-side seat is improperly positioned

• Is the floor normal?

Yes

Go to the next step.

No

Repair floor deformation, then go to the next step.

3

• Install the passenger-side front seat. (See FRONT SEAT REMOVAL/INSTALLATION.)

• Reconnect the disconnected connectors.

• Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

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

• Perform seat weight sensor calibration. (See SEAT WEIGHT SENSOR CALIBRATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

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

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

• Is the same DTCs present?

Yes

• Replace the seat weight sensor control module. (See SEAT WEIGHT SENSOR CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

• Perform seat weight sensor calibration. (See SEAT WEIGHT SENSOR CALIBRATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

• Go to the next step.

No

DTC troubleshooting completed.

4

• Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

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

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

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

• Is the same DTCs present?

Yes

Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

No

DTC troubleshooting completed.
