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 DRIVER-SIDE SIDE AIR BAG MODULE 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 . Disconnect the driver-side side air bag module connector installed to the lower side of the seat cushion of the front seat. Is there any malfunction of the driver-side side air bag module connector?	Yes	Replace the driver-side side air bag module wiring harness.
1		No	Go to the next step.
2	INSPECT DRIVER-SIDE SIDE AIR BAG MODULE Switch the ignition to off Disconnect the negative battery cable and wait for 1 min or more Connect the SST (Fuel and thermometer checker) or apply 2-ohm resistance to the driver-side side air bag module connector terminals A-B. Set the SST (Fuel and thermometer checker) to 2 ohm Connect the negative battery cable Clear DTCs using the M-MDS (See CLEARING DTC .) Perform the DTC inspection for the SAS control module using the M-MDS. Are DTCs B1126:11, B1126:12, B1126:19, B1126:1A and/or B1126:1B displayed?	Yes	Go to the next step.
2		No	Replace the driver-side side air bag module. (See SIDE AIR BAG MODULE REMOVAL/INSTALLATION .)
3	INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND DRIVER-SIDE SIDE AIR BAG MODULE 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 the 2 ohm resistance. Disconnect all SAS control module connectors. Inspect the wiring harnesses between SAS control module connector terminal 1A and driver-side side air bag module connector terminal B, and SAS control module connector terminal 1C and driver-side side air bag module connector terminal A 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 driver-side side air bag module Is the wiring harness normal?	Yes	Go to the next step
3		No	Replace the wiring harness between the SAS control module and the driver-side side air bag module.
4	INSPECT THE WIRING HARNESS BETWEEN THE SAS CONTROL MODULE AND DRIVER-SIDE SIDE AIR BAG MODULE 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 1C and 1A of SAS control module harness side connector. NOTE: Measure the voltage while shaking the wiring harness between the SAS control module and driver-side side air bag module Is the voltage measured?	Yes	Replace the wiring harness between the SAS control module and the driver-side side air bag module
4		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 B1126:11, B1126:12, B1126:19, B1126.1A and/or B1126:1B displayed again? Are there other DTCs output?	Yes	Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION .)
5		No	DTC troubleshooting completed.
