For wiring diagram information, refer to appropriate SYSTEM WIRING DIAGRAMS article.

Theory of Operation

When powered, the occupant restraint controller sends a test current to the impact sensors. During this test, the impact sensors discovered are checked for agreement with the pre - programmed vehicle configuration of components assigned to the module. The repair of this fault condition does not involve any external circuitry and centers on confirming the correct module and wiring is installed in the vehicle.
