CIRCUIT OPERATION

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.
