My ABS and ESC light stays on when starting the car (especially when cold start i.e. in the morning or after few hours in cold weather) but when I started driving, the light will turn off after less than a minute. After a drive when I park and turn off for a while (e.g. grocery run, etc.), this issue didn't come up..
My initial guess is the battery since I'm currently using a smaller battery (in terms of size) than the original. But could this be an ECU issue? Any help is appreciated.
