Light Flash Codes (Lfc)
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
When Restraints Control Module (RCM) detects system fault, it will cause AIR BAG warning light to flash a coded sequence, a LFC consisting of 2 digits. The first digit is flashed with a 0.5 second interval between pulses. There is a 2 second pause before the second digit is flashed, which also has a 0.5 second interval between pulses. There is a 5 second interval between each display of an LFC.
Each LFC is flashed 5 times, after which, the AIR BAG warning light will remain lit for the remainder of the key-on cycle. If there are multiple LFCs, each LFC will flash in order of priority. Each LFC has one or more associated diagnostic test codes (DTCs)
