Obd 2 port always on

Alan Bowman · 2022-01-10T20:43:20+0000

Can I switch the obd 2 port to turn on with the key? It’s always on. Cannot figure it out. Thanks! 2016 5.3 silverado i just installed a SCT programmer and I wanna leave it in the truck but not if it won’t shut off when the key is not even in the ignition.

  Got a call today scheduling the bumbers for next week. Can't wait. That's the last major change, stuff they owed me, scheduled for next week. I'm not sure what I'm looking at. Looks like a draft from last week. Bumpers were installed today by the dealer. I'm very happy with the results. A couple before afters ... or not. looks like I can only get 2 into a single post.

  I've referred to this many times over the years and I've had zero issues after the installation. Also, it helped a friend of mine resolve transmission issues he was having with his 2018 GMC Sierra. Chevrolet TSB 21-NA-199.pdf

  Seems to be a BCM issue. Have it scanned and checked for codes. Erase all faults and see if the issues return. If so, you might want to reach out to White Automotive for a BCM replacement.
