• 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.
