Computer problem
1997 Nissan Maxima 6 cyl Front Wheel Drive Automatic

I retrieved a diagnostic trouble code that reads, P0600: Serial Communication Link. I can't find a more information on it, like more of an explination of what the problem could be. If any can explain to me more about this code I would really appreciate it a lot.

-Thank you,
