It can be connected to a PC to upgrade the software etc via the usb port.What is the usb connection for? Can it be connected to a PC, or are the controls only from the screen?
Have a search around on youtube - in one of the demo videos the guy shows how to navigate to the correct menu to resynch BECM and ECU. I'll have a quick look myself for the video, if I find it I'll link here.I've only had a limited play with it but I can't see any settings that would let you sync the BECM with the ECU. My unit won't communicate with the HEVAC ecu (for error codes etc) but everything else seems OK. On several occasions the unit has locked up needing a restart but this seems happen more when I'm inpatient and pressing the buttons really quick so maybe this is a user issue. I'm going to slow down the input speed and see if this sorts that out.
Oh man... I can't wait to get this! My occasional book symbol has been haunting me for a year!Mine is excellent.
No problem comunicating with HEVAC in fact just fixed my long time book symbol ,changed the heater core temp sensor and fault cleared. Have you updated to the latest software 1.06 ?
