Hello. My father was driving his '99 Ram 1500 on the interstate. All of a sudden his brake and ABS lights lit up on the dash. He pulled over and walked around the vehicle to see if he could see anything wrong, but couldn't. He decided to continue on to his destination and noticed the speedometer is not working either. Any suggestions on what might be wrong? Thanks in advance.

 

Output speed sensor in the tranny ???

 

or it might be the vehicle speed sensor at the wheels. and when your abs light comes on it will cause you to lose abs power, it is the same as if u pull out the light bulb. you will be able to lock up your tires.
