Lamp Fault Codes (LFC)
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
When the restraints control module (RCM) detects a system fault, it will flash a coded sequence which is called a lamp fault code (LFC) on the air bag warning indicator located in the instrument cluster (IC) module. The code is 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 indictor will remain lit for the remainder of the key-on cycle (except for DTC B2792 [cross link between firing loops] which only flashes one LFC). If there are multiple LFCs, each LFC will flash in order of priority.
