Problem of my MONTERO car,, is no Signal Light,, no wiper,,headlights lowbeam and park light always on even the switch is off,,
my friend said ETACS ECU failure,,, ,
IS IT TRUE THE ETACS ECU IS THE PROBLEM?? Please give me some advice??

 

Not familiar with the new Montero Sport, but based on reading about what ETACS system is controls, it sounds like that is where the problem is. Most likely you are going to have to take it to a dealer for confirmation and work on that.
