Seating and safety restraints 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 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. A 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 on. If any of these indications 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.
