Service Theft Deterrant System

[Brittanyb2214]

Within the last couple weeks my 2015 Tahoe LTZ started throwing a bunch of service codes along with the service theft deterrant system. It will not allow the vehicle to start and at times my guages do not work at all. The battery is newer, and I have not had any new keys made for the vehicle. I can reset the system by unhooking the battery, but I am a social worker and I travel a lot for work. It's not exactly convenient to have to sit in a clients driveway for 15 minutes to reset the system. Had anyone had to service their theft deterrant system?

You really need to scan those codes to even know where to start. I’d either get a scanner (or borrrow one) or unfortunately a dealer visit to Atleast diagnose and pull codes. Then if they come back with the problem you can elect to fix it yourself cheaper.
