first check all the fuses (control fuses and main buss fuse)

i would check the U , V, W cables connecting to the traction inverter and make sure they are tight and no signs of melting around the terminal on the inverter case around the terminal.

also check the connectors at the logic card and you can also remove the logic card and take the cover off and check the circuit boards inside and make sure there are no burnt areas there.
