Ok I have done my Research and everything On this….my 4×4 is not working and it is throwing speed sensor code(code 2) for the front Speed sensor….I have replaced both sensors with new oem Sensors cleaned all plug ins and tested every wire.the bike has new axles diff oil and the output shaft is not stripped tires are all the same size and air pressure is correct….is there anything else I can do to get the 4×4 working? It almost as if it’s not reading the ring gear on the front diff but IK the sensor is good. I’ve chasesd this problem for 3 weeks now with no luck and spent 200 on sensors please help me.
