A blown fuse can cause the dashlights and taillights to stop working on a 2001 Dodge 1500.
The abs and brake light come on when the computer detects a problwm and sets a code. After reading the code, and repairing the cause of the code, you clear the code with a scan tool.
Fuse, bulbs, switch, wiring.
You need to have the abs checked for codes. Then you can diagnose cause.
A short in the wiring (grounding out)
Cracked electrical wire caused this to my car once.
It is most likely the fuse. Try replacing it.
switch dead short bad wire test wires or trace system out
Check the fuses and if they are good then check the brake light switch.
The light will reset itself when the cause of the code has been repaired.
That is information that the car companies will not release.
