WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects a open or short to battery, it will store diagnostic trouble code (DTC) C1982 in memory and flash lamp fault code (LFC) 49 (or higher priority code if one exists) on the air bag indicator.
