Diagnostic Procedure

Step

Inspection

Action

1
INSPECT PASSENGER-SIDE SIDE AIR BAG SENSOR
Warning
•  Handling the component parts improperly can accidentally operate (deploy) the air bag modules and pre-tensioner seat belts, 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 cable and wait for 1 min or more.
•  Verify that the passenger-side side air bag sensor is correctly installed.
•  Is the passenger-side side air bag sensor correctly installed?
Yes
Go to the next step.
No
Correctly install the passenger-side side air bag sensor.
Then go to the next step.
2
INSPECT PASSENGER-SIDE SIDE AIR BAG SENSOR CONNECTOR
•  Switch the ignition off.
•  Disconnect the negative battery cable and wait for 1 min or more.
•  Remove the passenger-side B-pillar lower trim.
•  Disconnect the passenger-side side air bag sensor connector.
•  Inspect the passenger-side side air bag sensor connector. (Corrosion, damage, and disconnected pins)
•  Is there any malfunction of the passenger-side side air bag sensor connector?
Yes
Replace the malfunctioning part, then go to Step 6.
No
Go to the next step.
3
INSPECT PASSENGER-SIDE SIDE AIR BAG SENSOR CIRCUIT FOR SHORT TO GROUND
•  Remove the column cover.
•  Disconnect the clock spring connector.
•  Remove the glove compartment.
•  Disconnect the passenger-side air bag module connector.
•  Disconnect the driver and passenger-side front seat connectors.
•  Remove the B-pillar lower trim.
•  Disconnect the driver and passenger-side pre-tensioner seat belt connectors.
•  Remove the headliner.
•  Disconnect the driver and passenger-side curtain air bag module connectors.
•  Disconnect the all SAS control module connectors.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  SAS control module terminal 1P
―  SAS control module terminal 1R
Note
•  Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side side air bag 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 passenger-side side air bag 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 6.
No
Go to the next step.
4
INSPECT PASSENGER-SIDE SIDE AIR BAG SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Passenger-side side air bag sensor and SAS control module connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Passenger-side side air bag sensor terminal A—SAS control module terminal 1P
―  Passenger-side side air bag sensor terminal B—SAS control module terminal 1R
Note
•  Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side side air bag 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 passenger-side side air bag 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 6.
5
INSPECT PASSENGER-SIDE SIDE AIR BAG SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY
•  Passenger-side side air bag sensor and SAS control module connectors are disconnected.
•  Connect the negative battery cable.
•  Switch the ignition ON (engine off or on).
•  Measure the voltage at the following terminals (wiring harness-side):
―  SAS control module terminal 1P
―  SAS control module terminal 1R
Note
•  Measure the voltage while shaking the wiring harness between the SAS control module and passenger-side side air bag sensor.
•  Is the voltage 0 V?
Yes
Replace the passenger-side side air bag sensor, then 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 side air bag 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.
6
PERFORM SAS CONTROL MODULE DTC INSPECTION
•  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.
•  Switch the ignition ON (engine off or on).
•  Clear the DTC for the SAS control module using the M-MDS.
•  Perform the DTC inspection for the SAS control module using the M-MDS.
•  Are the same DTCs present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the SAS control module.
No
DTC troubleshooting completed.
