no.
If you take it to the dealer, you will deal with guesswork or a bid to replace thousands of dollars worth of stuff...
You'd need to scan modules and try to figure out which is failing/failed.... and that is just a guess.
ISTA can be downloaded...the cable can be a fiddle, but maybe look into it?
