How do I tell if the computer/ecu is bad

You probably should check the condition of your battery, key fob batteries, and scan for codes. Also check to make sure the brake light switch is working and let us know what you have discovered.

Start with diagnostic codes. You might need someone with a star machine to run a diagnostic

Start by testing the car battery, make sure its not dead. Take a volt meter, test it. A good battery, should have a output, of 12.4 volts. Thats probably what’s wrong.
