Test Q: Driver-Side Air Bag Circuit Resistance Low (DTC B1934): Description
WARNING: This page is about a different car, the 2004 Ford Econoline. 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 terminals No. 1 (Gray/Orange wire, circuit No. 614) and No. 2 (Gray/White wire, circuit No. 615). If RCM detects low resistance between these terminals, it will store Diagnostic Trouble Code (DTC) B1934 in memory and flash Code 19 on AIR BAG warning light.
