System malfunction location

• Seat weight sensor calibration setting invalid

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.

• Calibration set value not within valid range.

Fail-safe

Not applicable

Possible cause

• Seat weight sensor deformed or malfunction

• Load to or deformation of the seat belt rail

• Deformed front passenger-side seat under-bracket or frame

• Weight acting on front passenger-side seat during calibration

• Improperly installed front passenger-side seat part at time of calibration

• Deformed floor where attached to front passenger-side seat

• Seat weight sensor control module malfunction

• SAS control module malfunction

Step

Inspection

Action

1

• Perform the SAS control module configuration using the M-MDS. (See SAS CONTROL MODULE CONFIGURATION (USING AS-BUILT DATA) [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 DTC present?

Yes

Go to the next step.

No

DTC troubleshooting completed.

2

• Switch the ignition off.

• Disconnect the negative battery cable and wait for 1 min or more. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

• Remove the passenger-side seat and visually inspect for the following:

• Seat under-bracket deformation

• Seat frame deformation

• Seat weight sensor deformation

• Foreign objects stuck in seat

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

Yes

Replace any deformed parts or remove any foreign objects.

• After replacement, perform seat weight sensor calibration and reperform the DTC inspection. If the DTC is displayed, go to the next step. (See SEAT WEIGHT SENSOR CALIBRATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

No

Go to the next step.

3

• 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.

• After repair, perform seat weight sensor calibration and reperform the DTC inspection. If the DTC is displayed even though the floor has been repaired, go to the next step. (See SEAT WEIGHT SENSOR CALIBRATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

4

• Replace the seat weight sensor.

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

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

• After replacement, perform seat weight sensor calibration. (See SEAT WEIGHT SENSOR CALIBRATION [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 DTC present?

Yes

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

• After replacement, perform seat weight sensor calibration and reperform the DTC inspection. If the DTC is displayed even though the seat weight sensor control module has been replaced, replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

No

DTC troubleshooting completed.
