I had an error on my van stopping it from booting from the startup smith screen. If there are any faults the screen will just display the "Smith logo". I ran the scanner software and found I had the high voltage interlock error. Tracking that down can be a pain in the butt. Its referred to as the Evil loop. It really is just that a loop that goes into every connection on every system. I think I sent you the plans that show the loop, look for the interlock wires.
But the very very first thing I would do is remove each of the orange high voltage disconnect "pucks" and place them back on, but when you place them on make sure you pull the "handle outwards, then rotate them closed otherwise they will not connect the interlock at the connector. I managed to fix my loop issue with a loose wire, but still had a HV interlock issue which caused by one of the orange pucks. That was one of the root causes of the failure to start up.
I will see what I can do to get you the software. You will need a CAN adaptor specifically a PEAK USB CAN Adapter IPEH 002021. They are on Ebay used for about $150 and will work with the software. Someone local may have one you can rent or borrow. Also you will need a functioning laptop.
