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 • safety belt pretensioners • 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, the air bag ignitors and safety belt pretensioners. 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 Instrument cluster chapter. Routine maintenance of the air bag is not required. Any difficulty with the system is indicated by one or more of the following: • The readiness light will either flash or stay lit • The readiness light will not illuminate immediately after ignition is turned to the RUN position • A series of five beeps will be heard. The tone pattern will repeat periodically until the problem and/or light are repaired. If any of these things happen, even intermittently, have the SRS serviced at your dealership or by a qualified technician immediately. Unless serviced, the system may not function properly in the event of a collision. 104
