Recently went to start CTS and wouldn't start right up. After a few tries, started up but theft light stayed on when started until engine was shut off and re-started. This happened once before, but didn't think anything of it as it was a very cold winter day and started after a couple of tries. Checked my onboard computer and came upon code P1629H, Theft Deterrent System-Cranking Signal. What causes this to happen and what can I do to correct this situation and prevent it from happeing again. Also, is this something that can be corrected by myself or will I have to bring it in to the dealership? If so, what does it run to fix this.
Thanks
