  (See AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM].) (See AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP 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.)

• Remove the passenger-side lower panel.

  (See PASSENGER-SIDE LOWER PANEL REMOVAL/INSTALLATION.)

• Disconnect the passenger-side air bag module (inflator No.1) connector.

  (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

• Inspect the passenger-side air bag module (inflator No.1) connector. (Corrosion, damage, and disconnected pins)

• Is there any malfunction of the passenger-side air bag module (inflator No.1) connector?

Yes

Replace the malfunctioning part, then go to Step 6.

No

Go to the next step.

2

• Remove the column cover.

  (See COLUMN COVER REMOVAL/INSTALLATION.)

• Disconnect the driver and passenger-side lap pre-tensioner seat belt connectors.

  (See SEAT BELT REMOVAL/INSTALLATION.)

• Disconnect the all SAS control module connectors.

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

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

• SAS control module terminal 3K

• SAS control module terminal 3N

NOTE:

• Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module (inflator No.1).

• 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 passenger-side air bag module (inflator No.1) 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 6.

No

Go to the next step.

3

• Passenger-side air bag module (No.1)and SAS control module connectors are disconnected.

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

• Passenger-side air bag module (inflator No.1) terminal 1A—SAS control module terminal 3K

• Passenger-side air bag module (inflator No.1) terminal 1B—SAS control module terminal 3N

NOTE:

• Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module (inflator No.1).

• 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 passenger-side air bag module (inflator No.1) 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 6.

4

• Passenger-side air bag module (inflator No.1) and SAS control module connectors are disconnected.

• Connect the negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

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

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

• SAS control module terminal 3K

• SAS control module terminal 3N

NOTE:

• Measure the voltage while shaking the wiring harness between the SAS control module and passenger-side air bag module (inflator No.1).

• Is the voltage 0 V?

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 passenger-side air bag module (inflator No.1) 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 Step 6.

5

• Switch the ignition off.

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

• Connect the SAS control module connectors.

• Except for the passenger-side air bag module (inflator No.1) connector, reconnect all disconnected connectors.

• Connect the SST (Fuel and thermometer checker) or apply 2 ohms resistance to the passenger-side air bag module (inflator No.1) connector terminals 1A and 1B.

• Set the SST (Fuel and thermometer checker) to 2 ohms.

• Connect the negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

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

• Clear the DTC for the SAS control module using the M-MDS.

  (See CLEARING DTC [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

• Perform the DTC inspection for the SAS control module using the M-MDS.

  (See DTC INSPECTION [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

• Are the same DTCs present?

Yes

Go to the next step.

No

Replace the passenger-side air bag module (inflator No.1).

(See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

Then go to the next step.

6

• Switch the ignition off.
