The 2004.5 Spectra is the first Kia vehicle sold in the
U.S. to combine the ETACS/IBEC, includes the interior
in-panel junction box, relay box, and fuse box, into
one unit.
In service documents, there may be references to a
BCM associated with the 2004.5 Spectra. The 2004.5
Spectra is equipped with an ETACS but not a BCM.
While both BCM and ETACS appear to perform similar
functions, the BCM has a processor that controls body
electrical functions while the ETACS is a controller that
facilitates input signals and body electrical functions
through a series of relays and actuators.
