Light Flash Codes (Lfc)
WARNING: This page is about a different car, the 2004 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
When RCM detects a system fault, it will cause AIR BAG warning light to flash a coded sequence. The code consists 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 pause between each display of an LFC.
Each LFC is flashed 3 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.
