Test V: Driver-Side Air Bag Circuit Resistance Low (DTC B1934): Description
WARNING: This page is about a different car, the 2002 Ford Pickup, 2002 Ford F550 Super Duty, 2002 Ford F450 Super Duty, 2002 Ford Excursion, and 2002 Ford Cab & Chassis. 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. 3 (Gray/Orange wire, circuit No. 614) and No. 4 (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 34 on AIR BAG warning light.
