VERIFY WHETHER MALFUNCTION IS IN
DRIVER-SIDE AIR BAG MODULE (INFLATOR
NO.2) OR RELATED WIRING HARNESS

• Connect leads of SST (Fuel and

thermometer checker) or apply 2 ohm
resistor to driver-side air bag module (inflator
No.1) connector terminal 3A and 3B, and
driver-side air bag module (inflator No.2)
connector terminal 4A and 4B.

• Set resistance of SST (Fuel and

thermometer checker) to 2 ohm.

• Connect negative battery cable.

• Turn ignition switch to ON position.

• Check following PID/DATA monitor, using

SST (WDS or equivalent).
