Air Bag Control Module: Description and Operation
SYSTEM OPERATIONAirbag Control Module Location:
The Airbag Control Module (ACM) contains the safing sensor and energy reserve capacitor. The safing sensor is located inside the ACM. The module is mounted on the tunnel/floor pan between the gearshift lever and the park brake lever. The safing sensor provides confirmation of a crash, but does not discriminate severity. The ACM monitors the system to determine the system readiness. The ACM contains on-board diagnostics, and will illuminate the AIRBAG warning lamp in the cluster when a fault occurs. The warning equipment is tested for six to eight seconds every time the vehicle is started.
