Hello,

It sounds like the throttle actuator is having a problem, but to be sure lets run the codes to see what comes up. This guide will show you how but the connection will be different since it is in Japan.

Please run down this guide and report back.

Cheers, Ken

Not really, its such a new car it might need to go to the dealer for a program update. Either way need to run the codes. Let me know what happens please.

Hi Ken,

Hope you are doing well!

I have checked it with scanner, everything was okay, except idling-stop.
It comes with the code of (P1382 (starter control module)).
Mechanic said replace the battery. That is why Eco-idling is not working.
So what should I do now?

Thanks in advance.

A weak battery can cause issues let's test it first by following this guide.

If okay I would replace the starter module, Let me know how the test turns out.

Yep the starter module is next which may need to be initialized by a shop. I would see if you can get a used one first and plug it in to see what happens.
