I'm not getting power to my dlc checked all the fuses and they're good replaced some anyways to verify. And still getting nothin. I have a check engine light and I'm trying to figure out what it is and I tried the key trick and only get p1693 p done then back to the trip. Any help is appreciated I've been searching for the answer the last few days an nothing is helping really

Welcome to the forum Cory.

 

I am pulling a blank on what "DLC" is?

 

Take a few moments and fill out your signature to let us know more about your ride and mods if any.

Data link connection. I'll do the signature right now thanks for the welcome

Make sure the pins are not pushed out of the connector under the dash for the OBDII port, have seen this happen several times. Check that all wires are pushed into the connector and that when you hook up a reader or programmer it doesn't push them out the back. Then you can start pinning out the harness for issues.

IOD (Ignition Off Draw) fuse. It's the one in the funky clip. This fusee powers the OBDII port.

Fuse is good just replaced it. I'll get some more an try again

OK so I got a test light and it was a bad connection on my part. Truck was previously stolen and they cut the dlc wires and my connection wasn't very strong on the power wire. Got it fixed pulled 6 codes I'll list them. P0381 P0382 P1698 P1689 P0602 P0380

Next is to clear them and see which ones come back if any.

 

Code list here.
