Test Ab: Air Bag Tone Warning Indicator Circuit Short To Ground Or Open (DTC B1892): Description
WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) monitors its connection to instrument cluster at RCM connector C2041A, terminal No. 26 (Light Blue/Black wire). This connection is used to signal a chime if AIR BAG warning light is inoperative and another air bag system fault exists. If RCM detects a short or open on connection to instrument cluster, it will store Diagnostic Trouble Code (DTC) B1892 in memory.
