DIAGNOSIS AND TESTING (Continued)
Each LFC is flashed five times after which the airbag
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.
Diagnostic Trouble Codes (DTCs)
While the lamp fault codes (LFCs) are an indication of
a general concern in the passive restraints system,
the diagnostic trouble codes (DTCs) are more
specific. The DTCs can be retrieved from the
restraints control module (RCM) with a scan tool via
the data link connector (DLC).
