WARNING:

• Handling the component parts improperly can accidentally operate (deploy) the air bag module, which may seriously injure you. Read the service warnings/cautions and the workshop manual before handling the air bag system components.

  (See AIR BAG SYSTEM SERVICE WARNINGS [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See AIR BAG SYSTEM SERVICE CAUTIONS [STANDARD DEPLOYMENT CONTROL SYSTEM].)

• 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 front bumper. (See FRONT BUMPER REMOVAL/INSTALLATION.)

• Disconnect the crash zone sensor connector. (See CRASH ZONE SENSOR REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

• Inspect the crash zone sensor connector. (Corrosion, damage, and disconnected pins)

• Is there any malfunction of the crash zone sensor connector?

Yes

Replace the malfunctioning part, then go to Step 5.

No

Go to the next step.

2

• Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION.)

• Disconnect the clock spring connector. (See CLOCK SPRING REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

• Remove the glove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

• Disconnect the passenger-side air bag module connector. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

• Disconnect the driver and passenger-side front seat connector. (See FRONT SEAT REMOVAL/INSTALLATION.)

• Remove the headliner. (See HEADLINER REMOVAL/INSTALLATION.)

• Disconnect the driver and passenger-side curtain air bag module connector. (See CURTAIN AIR BAG MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

• Remove the B-pillar lower trim. (See B-PILLAR LOWER TRIM REMOVAL/INSTALLATION.)

• Disconnect the driver and passenger-side pre-tensioner seat belt connector. (See FRONT SEAT BELT REMOVAL/INSTALLATION.)

• Remove the rear console. (See REAR CONSOLE REMOVAL/INSTALLATION.)

• Disconnect the all SAS control module connectors. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

• Inspect for continuity between the following terminals (wiring harness-side) and body ground:

• SAS control module terminal 3O

• SAS control module terminal 3N

NOTE:

• Inspect for continuity while shaking the wiring harness between the SAS control module and crash zone sensor.

• Is there continuity?

Yes

Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and crash zone sensor terminal.

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.

• Replace the malfunctioning part.

If there is no common connector:

• Replace the wiring harness which has a short to ground.

Go to Step 5.

No

Go to the next step.

3

• Crash zone sensor and SAS control module connectors are disconnected.

• Inspect for continuity between the following terminals (wiring harness-side):

• Crash zone sensor terminal A—SAS control module terminal 3O

• Crash zone sensor terminal B—SAS control module terminal 3N

NOTE:

• Inspect for continuity while shaking the wiring harness between the SAS control module and crash zone sensor.

• Is there continuity?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and crash zone sensor terminal.

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

• Replace the malfunctioning part.

If there is no common connector:

• Replace the wiring harness which has an open circuit.

Go to Step 5.

4

• Crash zone sensor and SAS control module connectors are disconnected.

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

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

• Measure the voltage at the following terminals (wiring harness-side):

• SAS control module terminal 3O

• SAS control module terminal 3N

NOTE:

• Measure the voltage while shaking the wiring harness between the SAS control module and crash zone sensor.

• Is the voltage 0 V?

Yes

Replace the crash zone sensor, then go to the next step. (See CRASH ZONE SENSOR REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

No

Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and crash zone sensor terminal.

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.

• Replace the malfunctioning part.

If there is no common connector:

• Replace the wiring harness which has a short to power supply.

Go to the next step.

5

• Switch the ignition off.

• Disconnect the negative battery cable and wait for 1 min or more.

• Connect the SAS control module connectors.

• Reconnect all 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).

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

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

• Are the same DTCs present?

Yes

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

No
