STEP
3 VERIFY WHETHER MALFUNCTION IS IN
DRIVER-SIDE SIDE AIR BAG MODULE OR
RELATED WIRING HARNESS
• Connect the leads of the SST (Fuel and
thermometer checker) or apply 2-ohm
resistance to driver-side side air bag module
connector terminals A and B.
• Set the resistance of the SST (Fuel and
thermometer checker) to the 2-ohm
position.
• Connect the negative battery cable.
• Turn the ignition switch to the ON position.
• Are DTCs B1992, B1993, B1994, and/or
B1995 indicated?
4 INSPECT SAS CONTROL MODULE
• Turn the ignition switch to the LOCK position.
• Disconnect the negative battery cable and
wait for 1 min or more.
• Connect the driver-side side air bag module
connector.
• Turn the ignition switch to the ON position.
• Are DTCs B1992, B1993, B1994, and/or
B1995 indicated?
