Glossary of Terms

Active Codes: A malfunction that is present now.

Air Bag Control Module (ACM): ACM refers to either of the two types of air bag control modules Chrysler uses.
- The ASDM system is a mechanically-triggered system utilizing two front impact sensors and a sensor inside the module.
- The AECM (AB, AS and JA bodies only) is an electronically-triggered system that uses only its own internal electronic sensor to trigger the air bags.

ASDM: Air bag System Diagnostic Module (also called the Airbag Control Module (ACM)).


Air Bag Module: Also called "Squib" initiator - located inside the air bag module assembly.

DAB: Driver Air Bag

DRBII Diagnostic Readout Box II - Chrysler proprietary diagnostic scan tool.

Impact Sensor: G force sensitive, threshold switches which close when an impact of sufficient force in the correct direction occurs.
An impact switch closure accompanied by closure of the safing sensor, alerts the control module that it is now time to deploy the airbag(s).

Initiator: Also called "Squib" - located inside the air bag module assembly.

PAB: Passenger Air Bag

PASDM: Passenger Air Bag System Diagnostic Module

Safing Sensor: A switch inside the ASDM which must be closed at the same time at least one of the impact sensors is closed, to initiate deployment of the airbag(s).

Squib: Also called "Air Bag Module" initiator - located inside the air bag module assembly.

SRS: Supplemental Restraint System
