Lamp Fault Code (LFC)
When the restraints control module (RCM) detects a system fault, it will send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator and to flash a coded sequence which is called a LFC. 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. If there are multiple LFCs, each LFC will flash in order of priority.
