Normal Operation

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The restraints control module (RCM) monitors the resistance of the driver air bag ignitor by measuring the resistance between RCM C310a pins 1 and 2. If the RCM detects low resistance between these pins, it will store a diagnostic trouble code (DTC) B1934 in memory and flash lamp fault code (LFC) 19 (or higher priority code if one exists) on the air bag indicator.
