Air Bag Control Module: Description and Operation
Airbag Control Module (ACM) Location
The driver and passenger airbag system is a safety device designed to reduce the risk of fatality or serious injury, caused by a frontal impact of the
vehicle.
The Airbag Control Module (ACM) contains the impact sensor and energy reserve capacitor. The ACM monitors the system to determine the system
readiness. The ACM contains on-board diagnostics and will light the AIRBAG warning lamp in the message center when a problem occurs.
The impact sensor provides verification of the direction and severity of the impact. One impact sensor is used. It is located inside the Airbag Control
Module (ACM) which is mounted on a bracket, just forward of the center console. The impact sensor is an accelerometer that senses deceleration. The
deceleration pulses are sent to a microprocessor which contains a decision algorithm. When an impact is severe enough to require airbag protection, the
ACM micro processor sends a signal that completes the electrical circuit to the driver and passenger airbags. The sensor is calibrated for the specific
vehicle and reacts to the severity and direction of the impact.
