Problem:
Any idea why the theft light won’t go away? Truck starts and runs but theft light stays on? It is a 2019 silverado LT programmed by Autel IM608.
Fault code: B3031 security controller in learn mode.
Solution:
If you did all keys lost you need to program 2 keys in. If you did add key and light is on just disconnect the battery for about 20-30 seconds (or 3 to 5 minutes).
Car is stuck in learning mode til 2nd key is added. Need 2 keys so it comes out of security mode.
If there are not 2 keys programmed to this vehicle that light will stay on. If there are 2 keys programmed then perform a battery reset and it should go away.
Feedback:
I figured it needed a 2nd key just had to get my hand on a 2nd key luckily my order came in today and we No longer have a theft light on anymore.
