    CIRCUIT OPERATION1
    CIRCUIT OPERATION
    Ignition position 1 (Accessories)
    This feed is obtained from the BeCM via fuse 8 and
    is shared with the Radio, Front cigar lighter, Aerial
    amplifier and car phone (if fitted). The Ignition 1 is
    essential to the control panel as it provides power to
    the ECU although no functions or display on the LCD
    are possible.
    Ignition position 2
    This feed is obtained from the BeCM via fuse 17.
    Battery feed
    This feed is obtained from the fuse box via fuse 42.
    Ground Connection
    This feed runs down to a spliced joint, joining the
    main earth run down to fascia earth point 1.
    Dimmer Line
    This Pulse Width Modulated signal is provided by the
    BeCM.
    LCD Dimmer line
    This line is a input to the HEVAC and the signal is a
    inverse Pulse Width Modulated signal which is
    determined by the instrument pack.
    Alternator Charge signal
    This signal is given to the HEVAC ECU to inform it
    that the engine is running. This signal is active low.
    Diagnostic K line
    This line is used to communicate with the diagnostic
    equipment (TESTBOOK) and is normally held at 12V
    when not active
    Left/Right Recirculation motors
    These motors control the flaps on the blower motor
    modules. The flaps should be in one of two
    positions, either fully open or fully closed.
    Left/Right Blower modules
    The blowers have a permanent 12V feed to them.
    The speed of the motors is determined by the control
    lines which go to the motors. The motors also
    provide a voltage feedback to the HEVAC ECU to
    determine the actual voltage at the motors but also
    to show if there are any faults.
    Left/Right Blend and Distribution Motors
    These motors are controlled by the HEVAC ECU
    which provides power to the motors, which in turn
    report back their actual positions to the HEVAC
    ECU.
