Town Car V8-4.6L VIN W (1997)
-
If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor will attempt to remove deployment power by
turning on a solid state switch to open the 10 A fuse.
-
If the 10 A fuse has successfully been opened by the air bag diagnostic monitor, the air bag diagnostic monitor will not attempt to open it again
until the proper fault has been serviced and cleared. The air bag diagnostic monitor will store both the unwanted deployment diagnostic trouble
code and the loss of deployment power diagnostic trouble code. The loss of deployment power diagnostic trouble code is the highest priority.
WARNING: The back-up power supply energy must be depleted before any air bag component service is performed. To deplete the back-up
power supply energy, disconnect the battery ground cable and wait one minute to avoid accidental deployment and possible personal injury.
-
The air bag diagnostic monitor includes an internal back-up power supply. This feature provides sufficient backup power to deploy the air bags in
the event that the battery or battery cables are damaged in a collision before the crash sensors are activated. The back-up power supply will deplete
its stored energy approximately one minute after the negative battery cable is disconnected.
-
The air bag diagnostic monitor incorporates an internal safing sensor. Proper mounting of the air bag diagnostic monitor and bracket assembly is
critical to the function and performance of the air bag system.
-
The air bag diagnostic monitor and bracket assembly is non-serviceable and must be replaced as a unit in the event of failure.
