Air Bag Control Module: Description and Operation

SYSTEM OPERATION
The Airbag Control Module (ACM) contains the accelerometer and energy reserve capacitor. The ACM is mounted on the tunnel floor pan, forward of the center console. The accelerometer is located inside the ACM. The accelerometer provides confirmation of a crash, discriminating severity The ACM monitors the system to determine the system readiness. The ACM may store sufficient energy to deploy the airbags for only two minutes after the battery is disconnected. The ACM contains on-board diagnostics, and will illuminate the AIRBAG warning lamp on the cluster when a fault occurs. The warning equipment is tested for a few seconds every time the vehicle is started.
