Got couple of issues in the past with starting up which I attributed to old battery (car is 2007, bought by me couple of months ago), so I replaced it with a new one. Yesterday when I got home, I switched off the car (so the engine was hot), and tried to switch it on again a minute later. Pressing on the button doesn't produce crank. lights are dimmed on pressing, also it's possible to hear loud click sound on pressing and releasing of the button (so I suppose that break switch is working properly). After resting for 1 day, it still wasn't cranking, so I cleared eeprom by removing battery for 10 minutes, and miracle, it started without any hesitation. This brings me to think that it's something inside "brains", any suggestions on what it might be?
