Test L: Driver-Side Air Bag Low Resistance (DTC B1934): 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 resistance of driver-side air bag ignitor by measuring resistance between RCM connector C2041A, terminals No. 3 (Gray/Orange wire) and No. 4 (Gray/White wire). If RCM detects low resistance between these terminals, it will store Diagnostic Trouble Code (DTC) B1934 in memory and flash Code 34 on AIR BAG warning light.
