Use of Air Bag Simulators

A service tool is required to perform diagnosis and testing of the air bag system. The Rotunda Air Bag Simulator 105-00000 is a 1 ohm resistor used to simulate an air bag connection to the system. It is not acceptable to jump out the air bag connection with a 0 ohm jumper wire. If a 0 ohm jumper wire is used to jumper out the air bag connection, a system fault will be displayed (Fault Code 34 or 35) according to the priority scheme.

1. Disconnect positive battery cable.
2. Wait one minute. This is the time required for backup power supply in diagnostic monitor to deplete its stored energy.





3. Remove four nut and washer assemblies retaining driver air bag module to steering wheel. Disconnect driver air bag connector.





4. Connect air bag simulator to vehicle harness at top of steering wheel.
5. Connect positive battery cable.

NOTE: On vehicles equipped with EEC, when the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the EEC processor relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.
