---|---|---|---|
1
|
INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR NO.2) CONNECTOR
• Turn the ignition switch to the LOCK position.
• Disconnect the negative battery cable and wait for 1 min or more.
• Remove the glove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)
• Disconnect the passenger-side air bag module (inflator No.2) connector. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.)
• Inspect the passenger-side air bag module (inflator No.2) connector. (Corrosion, damage, and disconnected pins)
• Is there any malfunction of the passenger-side air bag module (inflator No.2) connector?
|
Yes
|
Replace the passenger-side air bag module (inflator No.2) wiring harness.
|
No
|
Go to the next step.

|
INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR NO.2)
• Connect the SST (Fuel and thermometer checker) or apply 2-ohm resistance to the passenger-side air bag module (inflator No.2) connector terminals A—B.
• Set the SST (fuel and thermometer checker) to 2 ohm.
• Connect the negative battery cable.
• Perform the DTC inspection for the SAS control module using the M-MDS.
• (See DTC DISPLAY.)
• Are DTCs B2229, B2231, B2233 and/or B2235 displayed.
|
Yes
|
Go to the next step.
|
No
|
Replace the passenger-side air bag module.

INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND PASSENGER-SIDE AIR BAG MODULE (INFLATOR NO.2)
• Turn the ignition switch to the LOCK position.
• Disconnect the negative battery cable and wait for 1 min or more.
• Disconnect the SST (fuel and thermometer checker) or 2 ohm resistance.
• Disconnect all SAS control module connectors.
• Inspect the wiring harnesses between SAS control module connector terminal 1D and passenger-side air bag module (inflator No.2) connector terminal A, and SAS control module connector terminal 1A and passenger-side air bag module (inflator No.2) connector terminal B for the following:
• Is the wiring harness normal?
|
Yes
|
Go to the next step.
|
No
|
Replace the wiring harness between the SAS control module and the passenger-side air bag module (inflator No.2).
|

4
|
INSPECT THE WIRING HARNESS BETWEEN THE SAS CONTROL MODULE AND PASSENGER-SIDE AIR BAG MODULE (INFLATOR NO.2) FOR A SHORT CIRCUIT TO THE POWER SUPPLY
• Connect the negative battery cable.
• Turn the ignition switch to the ON position.
• Measure the voltage of SAS control module connector terminals 1D and 1A.
• Is the voltage measured?
|
Yes
|
Replace the wiring harness between the SAS control module and the passenger-side air bag module (inflator No.2).
|
No
|
Go to the next step.

|
INSPECT DTCs
• Disconnect the negative battery cable and wait for 1 min or more.
• Connect the disconnected connector.
• Connect the negative battery cable.
• Clear DTCs using the M-MDS.
(See CLEARING DTC.)
• Verify DTCs using the M-MDS.
(See DTC DISPLAY.)
• Is DTC B2229, B2231, B2233 and/or B2235 displayed again?
• Are there other DTCs output?
|
Yes
|
Replace the SAS control module.
|
No
|
DTC troubleshooting completed.
