STEP

INSPECTION

ACTION

1

• Perform the instrument cluster DTC inspection using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].)

• Are any DTCs present?

Yes

Perform the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].)

No

Go to the next step.

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 [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 column cover. (See COLUMN COVER REMOVAL/INSTALLATION.)

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

• Remove the passenger-side lower panel.

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

• Disconnect the passenger-side air bag module connector.

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

• Disconnect the driver and passenger-side seat connectors.

  (See SEAT REMOVAL/INSTALLATION.)

• Remove the back trim.

  (See BACK TRIM REMOVAL/INSTALLATION.)

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

  (See SEAT BELT 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 the SAS control module connector terminal for poor connection (such as damaged/pulled-out pins, and corrosion).

• Is there any malfunction?

Yes

Replace the malfunctioning part, then go to the next step.

No

Go to the next step.

3

• Disconnect the instrument cluster connectors. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

• Inspect the instrument cluster terminal for poor connection (such as damaged/pulled-out pins, and corrosion).

• Is there any malfunction?

Yes

Replace the malfunctioning part, then go to Step 7.

No

Go to the next step.

4

• Instrument cluster and SAS control module connectors are disconnected.

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

• SAS control module terminal 3Q

• SAS control module terminal 3S

NOTE:

• Inspect for continuity while shaking the wiring harness between the SAS control module and instrument cluster.

• 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 instrument cluster 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 7.

No

Go to the next step.

5

• Instrument cluster and SAS control module connectors are disconnected.

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

• Instrument cluster terminal B???SAS control module terminal 3Q

• Instrument cluster terminal D???SAS control module terminal 3S

NOTE:

• Inspect for continuity while shaking the wiring harness between the SAS control module and instrument cluster.

• 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 instrument cluster 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 7.

6

• Instrument cluster 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 3Q

• SAS control module terminal 3S

NOTE:

• Measure the voltage while shaking the wiring harness between the SAS control module and instrument cluster.

• 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 instrument cluster 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.

7

• 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.)

• 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

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

No
