Deployment Protection Fuse: Description and Operation

If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor has an internal thermal fuse that will blow automatically. This removes all power to the air bag deployment circuit. The air bag indicator will flash the appropriate code to indicate the suspect circuit.

The thermal fuse is controlled by the diagnostic monitor and is not serviceable.

NOTE: The thermal fuse does not blow because of excessive current flowing through it. DO NOT attempt to jumper out the thermal fuse with a circuit breaker or any other type of fuse.
