Box Junction
Upper housing
Lower housing
The IBEC is made up of two parts: the upper and
lower housing assemblies. The upper housing contains
the terminals for fuses, relays and connectors. The
lower housing is a structure or frame that holds the
IBEC. These are press fit together.
The Press Fit Layer (PFL) type construction of the
electrical junction box offers greater durability and
heat resistance than a previous Printed Circuit Board
(PCB) type junction box and also allowes weight and
thickness to be reduced.
This construction also provides check holes permitting
measurement of ETACS voltages and resistances and
confirmation of ETACS board continuity, as shown in
the illustration. This aids in diagnostics by allowing
technicians to measure each circut.
