Heated Glass Element Relay: Description and Operation
Description
DESCRIPTION
The rear window defogger (EBL) relay (1) is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications
have common physical dimensions, current capacities, terminal functions and patterns (2). The ISO micro-relay terminal functions are the same as a
conventional ISO relay. However, the ISO micro-relay terminal pattern (or footprint) is different, the current capacity is lower, and the physical
dimensions are smaller than those of the conventional ISO relay. The EBL relay is a electromechanical device that switches battery current through a
fuse located in the integrated power module (IPM) to the rear window defogger grid and when equipped, switches battery current through another fuse
located in the IPM to the outside mirror heating grids. The EBL relay is energized when the relay coil is provided a ground path by the control circuitry
within the front control module (FCM).
The EBL relay is located in the IPM in the engine compartment.
