I'm having electrical issues my transmission is throwing these codes and my break lights don't work.this kind of stuff has been going on since someone tried to steal my truck 3 years ago the punched out my switch and every since then it does weird stuff like this .and way recently I had to replace e my replacement swich cylinder that I put in 3 years ago after attempted theft. And I married the new key to the truck like it said to do like I did the last one and it was fine fir about 2 weeks then this crap started happening. It lasted 4 days last time .them out of nowhere it is fine .that was a couple weeks ago now its happening again .how can I fix permanently what am I not doing?

Moved you here from General Discussion.

It matters, so please tell us what make, model, and year you're dealing with. Different types of security.

Married the key to your security system? Our keys dont have a chip or RF ID on them. Id pull the steering wheel apart and check the mounts for your security magnetic pickup module werent damaged or the module itself which has to be married to the BCM. Also check the clockspring. Dont forget to disarm the airbags!!!!

As far as the transmission goes, I would check fluid level first and verify it is NOT burnt. Then plan on a fluid change and have a look at the filter and see if it is plugged up. After all that then verify valves in valve body are not stuck and also have a look at wiring harness plug at the transmission and see if it is full of tranny fluid.
