I bought Nissan Days 2015 at the start of this month. I got it inspected with Pak Wheels and they advised me to change battery as the current battery was weak. So I got it change and installed New AGS (50 watts - 38 ampere) liquid battery. After changing battery I noticed that Eco Idle feature stopped working. Eco Idle light keeps blinking when I don't put seat belts. As soon I put my seat belt on Eco Idle light stops blinking but doesn't get activated.
Please recommend any mechanic which can fix this issue?
