BATTERY INSPECTION

• Refer to the battery inspection and inspect the battery.

(See BATTERY INSPECTION [MZR 1.5, MZR 1.6].)

(See BATTERY INSPECTION [MZR 2.0, MZR 2.5].)

(See BATTERY INSPECTION [MZR 2.0 DISI i-stop].)

(See BATTERY INSPECTION [SKYACTIV-G 2.0].)

(See BATTERY INSPECTION [MZ-CD 1.6].)

(See BATTERY INSPECTION [MZR-CD 2.2].)

• Is the battery normal?

Yes

Go to the next step.

Replace or charge the battery.

(See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)

FUSE INSPECTION

• Switch the ignition to off.

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

(See BATTERY REMOVAL/INSTALLATION [MZR 2.0, MZR 2.5].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].) (See BATTERY REMOVAL/INSTALLATION [MZ-CD 1.6].) (See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) (See BATTERY REMOVAL/INSTALLATION [MZR 1.5, MZR 1.6].)

• Remove the SAS 15 A fuse.

• Is the fuse normal?

Yes

Go to the next step.

Replace the SAS 15 A fuse.

INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND IG RELAY/IGNITION SWITCH

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.)

(See AIR BAG SYSTEM SERVICE CAUTIONS.)

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

• Disconnect the clock spring connector.

• 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.)

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

• Remove the C-pillar trim. (See C-PILLAR TRIM REMOVAL/INSTALLATION.)

• Disconnect the driver and passenger-side curtain air bag module connector (harness side). (See CURTAIN AIR BAG MODULE REMOVAL/INSTALLATION.)

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

• Disconnect the lap pre-tensioner seat belt connector. (See FRONT SEAT BELT REMOVAL/INSTALLATION.)

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

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

• Disconnect all SAS control module connectors. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)

• Connect the negative battery cable.

• Switch the ignition to ON.

• Measure the voltage of SAS control module connector terminal 3C.

Note

• Measure the voltage while shaking the wiring harness between the SAS control module and IG relay/ignition switch.

• Is the voltage 8.1–15.9 V?

Yes

Go to the next step.

Replace the wiring harness between the SAS control module and the IG relay/ignition switch.

INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND BODY GROUND

• Switch the ignition to off.

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

• Inspect the wiring harness between SAS control module connector terminal 3X and body ground.

Note

• Inspect for continuity while shaking the wiring harness between the SAS control module and body ground.

• Is the wiring harness normal?

Yes

Go to the next step.

Replace the wiring harness between the SAS control module and body ground.

PERFORM SAS CONTROL MODULE DTC INSPECTION

• Reconnect all disconnected connectors.

• Connect the negative battery cable.

• Switch the ignition to ON.

• 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 present?

Yes

Replace the SAS control module.

(See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
