My son in law was using my truck going to work, before this pandemic, now he is working at home. The truck set on the driveway never got started. He noticed the tail lights/backlight are ON (red), he can not figure out how to turn them off. He said the switch are off. Battery is dead. I got the battery jumper from my daughter car and truck started. The ABS light is ON while I was driving it to home and the tail light always ON. My suspect is, Looks like my tail lights are shorted or grounded, can not be controlled by switch. I don't think my truck has ABS brake system. Any idea or suggestion?
