4x4 indacator light flashes 4 times is this a voltage issue or ? also is it safe to ride till i fix it thanks

 

I know someone is going to hammer me on this...But I have [qoute] I have seen this happen...Check your tire pressure first.... Yes thats right...An low tire on these model can make the rotation of tire slower or faster then the other and the 4wd acturator can detect this an go in an fail code.... I know some people are laughing but I have seen this more times than not.....Just check pressure...It is on an plate on the left rear fender...Than we will go from there...
