Constant Monitoring

The following components of the air bag systems are monitored by a diagnostic system:


  • Crash sensors, and diagnostic module (SAS unit)

  • Front air bag sensors

  • Air bag modules

  • Side crash sensors

  • Air bag/Front seat belt pretensioner system warning light

  • Front seat belt pretensioners

  • Related wiring

(With Front Passenger Occupant Classification System)

  • Front passenger air bag deactivation indicator light

  • Front passenger occupant classification sensor

  • Front passenger occupant classification module


The diagnostic module continuously monitors the system's readiness. This begins when the ignition is switched ON and continues while the vehicle is being driven.
