I purchased my 2002 last month with 275k kms on it and it has been absolutely great. I haven't had a single issue yet and it has been running perfectly. But recently we had a snowfall so I was having some fun ripping around in 4wd with the rear diff locked when all of a sudden the front two wheels on the 4wd display (looks like the undercarriage of the vehicle) turned off. I'm not sure if this could be a light simply dying in the dash or is this an actual feature to tell me something is broken or disconnected? Any help on this would be appreciated because I am getting worrying I broke my baby. 
Also the 4wd still engages and disengages normally, along with the rear diff lock.
