Rejector circuit for heated rear window
The current to the conductors in the rear window is fed through 2 rejector circuits. The rejector circuits act as
throttles to reduce the transmission of interference pulses in the aerials from the vehicle electrical system.
A rejector circuit is integrated into the earth wire on the left-hand side of the rear window. An identical rejector
circuit is integrated into the positive (+) wire on the right-hand side of the rear window.
> E87
The rejector circuits are located in the tailgate under the rear window.
> E90, E92, E93
The rejector circuits are located on the left and right-hand sides under the C-pillar trim.
> E91
The rejector circuits are integrated in the interference suppression filter.
> R56
The rejector circuits are located in the tailgate under the rear window.
