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
(Active Low).
The HEVAC unit will control all timing functions
related to the rear screen heater.
