Ford Falcon. Manual - part 450

501-20b-15

Occupant Restraints — Passive

501-20b-15

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).
