Reactivating the anti-theft system on a Cadillac CTS is a complex task that requires a fuse map. First, turn off the vehicle and open the trunk to access the fuse panel. Take out the anti-theft fuse, then briefly power the car up before turning it off again. Return the fuse to its original position in the fuse box. You should now be able to restart your car and drive as usual. If this approach doesn't succeed, you will need a diagnostic scanner tool to resolve the issue.

To reset the anti-theft system on your Cadillac CTS, first turn on the car without starting the engine. Then, open the hood and locate the ECM fuse in the engine bay fuse panel. Remove the fuse labeled "ECM" for about 10 minutes before inserting it back in place.

Easy peasy - I used a simple PCM and anti-theft module to bypass it. I managed to do it in just 5 minutes using only a couple of jumpers.

Could you provide more details, Pat M? I'm looking for information on the location of the PCM and how you bypassed it. I own a 2009 Cadillac CTS that won't start, possibly due to anti-theft features.

The person who suggests turning your key, opening your trunk, and accessing your fuse panel clearly lacks knowledge about cars. It's important to gather information from multiple sources rather than relying solely on them. Being well-informed is crucial to prevent causing damage to your computer system, which can trigger various issues and result in the car being stuck in anti-theft mode. Make sure to verify the information you receive to avoid unnecessary expenses at the dealership. As someone who is not a service or dealership mechanic, my advice is based on truth and not influenced by personal gain.
