I just had a Viper alarm/remote start installed today. After it was installed I was driving and noticed on the dash that the D5 lights does not come on and the LCD display for which gear the shifter is in does not display. Would there be a cable that came loose for this? The lights for all other gears display except the D5.

 

happened to me as well but i didnt install anything , then the other day it randomly came back....
