My 4 wheel drive service display is on as well as my system traction disability .
The vehicle automatically disengaged traction system.

These are the only 2 problems so far.

I can switch from 2 wheel drive to 4H and 4L. When in these gears I'm able to drive backwards and forwards. The only thing is when 4H/L is engaged, the transfer to these gears are pretty loud clank. But none the less, it goes into gear.

Did it make this noise before the light was off?
