Secondary Air Bag Warning (Chime)
WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The secondary air bag warning chime, is an audible chime generated by the Lighting Control Module (LCM). If the Restraints Control Module (RCM) has detected a fault with the air bag warning indicator, a DTC will be stored in the memory of the RCM. Upon the RCM sensing that a Supplemental Restraint System (SRS) fault has been detected, the RCM will signal the LCM to sound the secondary air bag warning chime in a pattern of 5 sets of 5 beeps.
