Same, happened after battery died, somehow immo got deleted or something? Dealership can’t even figure it out

First, make sure the battery in the remote is good. Then put it in the little spot in the console, there is like a little place where you can put the key, which puts it very close to the Wi-Fi or Bluetooth that it’s talking to.

You need to get the owners manual. It’s all in there.

CommentNo power to trans fuse #20
Chevrolet Suburban 1995 k1500 275589 miles
I lost power to fuse #20 in the cabin fuse block. Can anyone share on where I can find a wiring diagram for that fuse and where it draws it's power from. I have power to the ECU/PCM and to and from the ignition switch.

Owners manual. It’s all in there pretty much. If you don’t have it, I don’t know what to tell you. Buy one?
CommentObd2 reader
Chevrolet Suburban 2003 1500 4x4 automatic 19800 miles
I hook up my OBD2 reader so the port and it runs through and gets just to the end and then it says has no communication and it says please turn off key and wait 10 seconds and check if key is in the ignition. Anybody got any ideas what's causing this? I had my throttle body going a week ago and the truck put it in past lock and mobilize the engine, so I had to bypass the passlock system so I can get the truck started and running. Now I got it working my OBD2 reader is not working. Anybody got any suggestions.
