WARNING: This page is about a different car, the 2004 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) monitors resistance of right side air bag module circuit loop and air bag igniter at RCM connector C2041B terminals No. 5 (White/Yellow wire) and No. 6 (Brown/Yellow wire). If RCM detects resistance more than 3.6 ohms, it will store Diagnostic Trouble Code (DTC) B1998 in memory and flash Code 37 on AIR BAG warning light.
