Airbag Control Module (ACM)
Airbag Control Module (ACM) Location:
The Airbag Control Module (ACM) is also sometimes referred to as the Occupant Restraint Controller (ORC). The ACM contains the sensing element, safing sensor, and energy reserve capacitor. The module is mounted on the tunnel/floor pan between the gear shift lever and the park brake lever.
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.
