Took a run down the highway to log emissions. After a few (3-5) minutes at 60mph the Brake,CST and ABS lights came on. Pulled off and restarted the car, drove back home and 3-5 min at 60mph the lights came back on. I replaced the battery and reconnected the siren. I ran the car for 30min at idle and no lights or errors showed. I’m thinking unplugging the siren was a bad idea
