Seating and safety restraints The SRS consists of: • driver and passenger air bag modules (which include the inflators and air bags). • side air bags (if equipped). Refer to Side air bag system later in this chapter. • one or more impact and safing sensors. • a readiness light and tone. • and the electrical wiring which connects the components. The diagnostic module monitors its own internal circuits and the supplemental air bag electrical system warning (including the impact sensors), the system wiring, the air bag system readiness light, the air bag back up power and the air bag ignitors. Determining if the system is operational The SRS uses a readiness light in the instrument cluster or a tone to indicate the condition of the system. Refer to the Air bag readiness section in the Instrumentation chapter. Routine maintenance of the air bag is not required. 107
