Lamp Fault Codes

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

This vehicle supports lamp fault codes (LFCs) only when the restraints control module (RCM) is in plant mode. A new RCM installed to a vehicle will be in plant mode until:

programmable module installation (PMI) has been carried out.
the RCM sees a fault-free supplemental restraint system (SRS) (no diagnostic trouble codes (DTCs) present).

If a LFC is present after completing PMI, a fault is present in the SRS and on-demand DTCs must be retrieved and diagnosed.
