Test U: Passenger Air Bag Circuit Resistance High (DTC B1933): Description
WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) monitors resistance of passenger-side air bag ignitor by measuring resistance between RCM connector terminals No. 6 (Light Blue/Orange wire) and No. 7 (Pink/Black wire). If RCM detects high resistance between these terminals, it will store Diagnostic Trouble Code (DTC) B1933 in memory and flash Code 33 on AIR BAG warning light.
