Hi Jim

My guess is you somehow caused a ground fault with the ignition switch on. At anypoint, you need to reset the DTC (diagnostic trouble code) if you think the fault is no longer present. If you didn't damage the PCM, things should clear up when you disconnect the ground cable for longer than 5 minutes. See my post at
http://www.cleanmpg.com/forums/showt...4068#post14068 for details on resetting KAM and DTC's.

In addition, if your HV battery is below 40%, the generator/motor will not start the ICE. If this is the problem, you need to follow the jump start proceedure outlined in the owner's manual. The HV battery can power the accessories and drain it down with the ignition switch on BTW.

Edit - Sorry, had to change 5 seconds to 5 minutes above.
