Diagnostic Procedure

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
Step Inspection Action
1 INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR NO. 2) 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 Service Information before handling the air bag system components.

    (See AIR BAG SYSTEM SERVICE WARNINGS .)

    (See AIR BAG SYSTEM SERVICE CAUTIONS .)


  • Switch the ignition to off
  • 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.
2 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 1C-1D
  • Set the SST  (fuel and thermometer checker) to 2 ohm  .
  • Connect the negative battery cable
  • Switch the ignition to ON
  • Clear DTCs using the M-MDS

    (See CLEARING DTC .)

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

    (See DTC INSPECTION .)

  • Are DTCs B0011:11, B0011:12, B0011:19, B0011:1A and/or B0011:1B displayed
Yes Go to the next step.
No Replace the passenger-side air bag module.
(See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION .)
3 INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND PASSENGER-SIDE AIR BAG MODULE (INFLATOR NO. 2) 
  • Switch the ignition to off
  • 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 3P and passenger-side air bag module (inflator No 2) connector terminal 1C, and SAS control module connector terminal 3N and passenger-side air bag module (inflator No 2) connector terminal 1D for the following:
    • Short to body ground
    • Open circuit
    • Short circuit between terminals
      NOTE:
      • Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side
  • 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.
  • Switch the ignition to ON
  • Measure the voltage of SAS control module connector terminals 3P and 3N
    NOTE:
    • Measure the voltage while shaking the wiring harness between the SAS control module and passenger-side air bag module.
  • 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.
5 INSPECT DTCs 
  • Switch the ignition to off.
  • Disconnect the negative battery cable and wait for 1 min or more  .
  • Reconnect all disconnected connectors
  • Connect the negative battery cable
  • Switch the ignition to ON.
  • Clear DTCs using the M-MDS

    (See CLEARING DTC .)

  • Verify DTCs using the M-MDS.

    (See DTC INSPECTION .)

  • Is DTC B0011:11, B0011:12, B0011:19, B0011:1A and/or B0011:1B displayed again?
  • Are there other DTCs output?
Yes Replace the SAS control module
(See SAS CONTROL MODULE REMOVAL/INSTALLATION .)
No DTC troubleshooting completed.
