Probably a bad speed sensor
Is there anything else it could be? Here’s why I ask -
- just got done installing new headlights and wired the LEDs for DRL
- battery died and had to recharge it
- attempted to install LED tail lights; they did the “stay on no matter what” and hyper flash blinker with associated “lamp out light”...took them out and put old lights back in.
- First start after tail light debacle (for op check) was when Abs and Brake light came on.
- Haven’t driven the truck in days
Thanks!
Quick edit/addition - there are NO associated codes.
