I purchased a new set of 28 mud bugs for my 2006 rubicon 4x4 fga ( electric shift) I went out for my first ride with them and my 4x4 stop working. The 4x4 indicator light blinked 2 times (front speed sensor)so I did the test that the honda manual suggested and Every time I do all 6 test it comes back saying its the front speed sensor so i replaced it. Still no 4x4! The light still blinks twice saying the front speed sensor. I went to the honda dealership and they told me the only way they would replace the sensor is if I brought my bike down and had a honda certified mechanic say the sensors faulty. I've check for power at the sensor, I've check for condunudity from the computer to the sensor(pink and white wire) which there was . Check condunudity to ground which there was none. Last test is to interchange the plug ins from the rear and front speed sensor and if the light blinks 3 times its your front speed sensor. Is it possible to be something else? Thank you.
