CIRCUIT OPERATION

The rear screen heater will reflect the state of the
heated rear screen input from the HEVAC unit at any
time while the BeCM (Z238) is in the active mode.
This signal is normally 12V and 0V when active (Ac-
tive Low).

The HEVAC unit will control all timing functions re-
lated to the rear screen heater.
