Diagnostic Procedure

Step

Inspection

Action
1
INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR NO.1 CONNECTOR
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.
•  Switch the ignition off.
•  Disconnect the negative battery terminal and wait for 1 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)
•  Remove the driver-side B-pillar lower trim. (See B-PILLAR LOWER TRIM REMOVAL/INSTALLATION.)
•  Disconnect the driver-side side air bag sensor No.1 connector. (See SIDE AIR BAG SENSOR NO. 1 REMOVAL/INSTALLATION.)
•  Inspect the driver-side side air bag sensor No.1 connector (wiring harness-side). (Corrosion, damage, and disconnected pins)
•  Is there any malfunction of the driver-side side air bag sensor No.1 connector (wiring harness-side)?
Yes
Replace the malfunctioning part, then go to Step 5.
No
Go to the next step.
2
INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR NO.1 CIRCUIT FOR SHORT TO GROUND
•  Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION.)
•  Disconnect the clock spring connector. (See CLOCK SPRING REMOVAL/INSTALLATION.)
•  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 connectors. (See FRONT SEAT REMOVAL/INSTALLATION.)
•  Remove the headliner. (See HEADLINER REMOVAL/INSTALLATION.)
•  Disconnect the driver and passenger-side curtain air bag module connectors. (See CURTAIN AIR BAG MODULE REMOVAL/INSTALLATION.)
•  Remove the B-pillar lower trim. (See B-PILLAR LOWER TRIM REMOVAL/INSTALLATION.)
•  Disconnect the driver and passenger-side front pre-tensioner seat belt connectors. (See FRONT SEAT BELT REMOVAL/INSTALLATION.)
•  Remove the trunk side trim. (See TRUNK SIDE TRIM REMOVAL/INSTALLATION.)
•  Disconnect the driver and passenger-side rear pre-tensioner seat belt connectors. (See SECOND-ROW SEAT BELT REMOVAL/INSTALLATION.)
•  Remove the selector lever component. (See AUTOMATIC TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION.)
•  Disconnect the all SAS control module connectors. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
?  SAS control module terminal 1AD
?  SAS control module terminal 1AF
Note
•  Inspect for continuity while shaking the wiring harness between the SAS control module and driver-side side air bag sensor 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 driver-side side air bag sensor 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 5.
No
Go to the next step.
3
INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR NO.1 CIRCUIT FOR OPEN CIRCUIT
•  Driver-side side air bag sensor No.1 and SAS control module connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
?  Driver-side side air bag sensor No.1 terminal A—SAS control module terminal 1AD
?  Driver-side side air bag sensor No.1 terminal B—SAS control module terminal 1AF
Note
•  Inspect for continuity while shaking the wiring harness between the SAS control module and driver-side side air bag sensor 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 driver-side side air bag sensor 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 5.
4
INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR NO.1 CIRCUIT FOR SHORT TO POWER SUPPLY
•  Driver-side side air bag sensor No.1 and SAS control module connectors are disconnected.
•  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)
•  Switch the ignition ON (engine off or on).
•  Measure the voltage at the following terminals (wiring harness-side):
?  SAS control module terminal 1AD
?  SAS control module terminal 1AF
Note
•  Measure the voltage while shaking the wiring harness between the SAS control module and driver-side side air bag sensor No.1.
•  Is the voltage 0 V?
Yes
Replace the driver-side side air bag sensor No.1, then go to the next step. (See SIDE AIR BAG SENSOR NO. 1 REMOVAL/INSTALLATION.)
No
Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and driver-side side air bag sensor 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 the next step.
5
PERFORM SAS CONTROL MODULE DTC INSPECTION
•  Switch the ignition off.
•  Disconnect the negative battery terminal and wait for 1 min or more.
•  Connect the SAS control module connectors.
•  Reconnect all disconnected connectors.
•  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL 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].)
•  Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [SAS CONTROL MODULE].)
•  Are the same DTCs displayed?
Yes
Repeat the inspection from Step 1.
•  Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
No
