Seating and safety restraints • and the electrical wiring which connects the components. The RCM (restraints control module) monitors its own internal circuits and the supplemental air bag electrical system warning (including the passenger air bag deactivation switch, 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 readiness lights in the instrument cluster and the passenger air bag deactivate switch or a tone to indicate the condition of the system. Refer to the Air bag readiness section in the Instrumentation chapter or Passenger air bag deactivate switch section in this chapter. Routine maintenance of the air bag is not required. A difficulty with the system is indicated by one or more of the following: • The readiness lights will either flash or stay lit. • The readiness lights will not illuminate immediately after ignition is turned on. • A series of five beeps will be heard. The tone pattern will repeat periodically until the problem and 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. Disposal of air bags and air bag equipped vehicles For disposal of air bags or air bag equipped vehicles, see your local dealership or qualified technician. Air bags MUST BE disposed of by qualified personnel. 98
