https://ibb.co/eRM5oJ Click on the link. Did you check for voltage at fuse, hot all the time. Use a test light to check for voltage. You see the security module toward the bottom and the park lamp relay. That should supply voltage for tail lamps. Sometimes depending on the issue, I bypass the module or relay, in your case, to see if lamps will work. Because it says security module, I don't know what will happen if you bypass? If that module is faulty and I don't know that it is, you would have to program a new module and I can't help you with that. I check voltage and grounds for any electrical components. Just my opinion.

Is there voltage at tan wire with white tracer at security module?
