Thanks everyone.
Basically I never play with the car's electronic because Im not at all familiar with electronics. I was just too mentally tired as it was a hectic day and I was doing this at night I was too tired picking up the battery and tipping it so I got a bit careless and it caused this to happen. However, I am very familiar with old school cars and even the latest technology and I do all my work myself without the assistance of mechanics but ECU se related cheezain aur electric components se bohot khof ata hai mujhe nahi samajh ati electronic games ecus ki.
Lets see what happens when I start up the car
