i had to replace the starter on my 3.7L today 8/31/19. i hook up a memory saver and disconnected the negative battery cable. well when i disconnected the positive cable from the starter
it touch the starter and sparked, i didn't think the system would be live but it was. that said i noticed the check engine light was on so i plugged in my autel model 529 and nothing
also noticed the gauges didn't function the jeep starts and drives so far. well i owned a 1999 mb c280 and had the same problem and on you tube showed me a 5 amp fuse to replace
problem fixed. i can not find a fuse labeled DLC or any relating to the problem. any ideas are welcome. Thanks

@Brickey;

Any information on this subject you should be able to find here;

https://www.jeepcommander.com/forums/10-electronics-nav-discussion/55657-junction-block-explained.html

If you can find it there, it probably doesn't exist; Loads of good information in that thread if you take the time to read it thoroughly and check out all of the attachments.

I’ve seen on some vehicles where the OBD connector shares a fuse with the cigarette outlets. You should probably just go ahead and check all of the fuses too.
