Hi,
Does anyone have a faulty FG2
ICC? That way it would be possible to look at which component is fried when the displays goes dead.
When you play with the display, most of the messages from the
HVAC system originate from the HIM (Heater Interface Module). On FG the
CAN bus from the
PCM and HIM goes via the instrument cluster (gateway) before arriving at the
ICC display.
The HIM exist as single zone or dual zone. (same hardware, can be re-flashed).
It would have been interesting to have a HIM hooked up to see what messages are sent. But I believe others have re-engineered that part when developing aftermarket control of the
HVAC / HIM.
Cheers,
