LAMP FAULT CODESWhen the restraints control module (RCM) detects a system fault, it will cause the air bag indicator to flash a coded sequence; a lamp fault code (LFC). The code is two 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.
The LFC is flashed three times after which the air bag indicator will remain illuminated for the remainder of the key-on cycle. If there are multiple LFCs, each code will be stored for retrieval by a diagnostic service tool, but only the highest priority LFC will flash.
Each LFC has one or more associated diagnostic trouble codes.
