Diagnostic Monitor

The air bag diagnostic monitor continually monitors all air bag system components and wiring connections for possible faults in the system. If the diagnostic monitor detects a fault in the air bag system when the ignition switch is in the ON position, a Diagnostic Trouble Code will be displayed on the air bag warning indicator. Performing system diagnostics is the main purpose of the diagnostic monitor. THE DIAGNOSTIC MONITOR DOES NOT DEPLOY THE AIR BAGS IN THE EVENT OF A CRASH! The crash sensors are "hard wired" to the air bags, and therefore, the crash sensors determine when to deploy the air bags.

Several important features of the air bag diagnostic monitor and its functions within the system are described below. It is necessary that you understand these key features and functions. They will enable you to better understand and perform more efficient air bag system diagnostics.
