Car won't start..(battery related possibly)

[Trevor]

Looking for some help or insight, I have a 2020 Toyota Supra RZ in Japan. I don't drive it much and recently it was sluggish to start occasionally. I went to a 7-11 a couple weeks ago and the engine wouldn't start. It was able to jump start and I drove it home. I left a trickle charge on it a few days. Last weekend I drove to work (car dealership) for Japans road inspection. I left it and went to work and then the engine hasn't cranked since. My dealers mechanic put a new toyota battery in it and it didn't work. Jumped from front and back and hasn't helped. Im trying to say what Ive seen as issues I read on this forum. I never got a warning about battery being low etc. Could it be a different issue? If I push the start button the electronics come on.. The language barrier and lack of knowledge makes it difficult. Thanks in advance.

Toyota put a new battery in it and now you can’t start it?

Sorry if my wording was hard to follow. I have a mechanic at my used car dealership I work at. He said he ordered a toyota battery specific to the car based on the chassis number from toyota. That did not start the car.

If I am not mistaken, you need to have a bmw based scanner to register the new battery. Or the Oem Toyota scanner. I want to say bimmer link can do it too.

I bought a JB4 system but I am a little afraid to try it with the battery being dead. We were told from Toyota (Not that it holds any weight) that the same battery swapped should start the car. I was contemplating hooking up the JB4 unit and trying to register the battery.

Get the car started first with the new battery. Worry ahout the jb4 later…..

The JB4 can register the battery? I thought it could. Only Bimmerlink can?

Oh this is when Zrk comes in and says something. I did not know Jb4 can register a new battery, must be something new…..

I mean I could be way off. Just thought it was possible. If I have to buy extra stuff I will.

No jb4 has no programing capabilities for the car. You can set maps on it, but has nothing to do with electronics and coding the car or making changes to features on the car.

Understood. Thank you. The blue tooth ob2 wouldn't connect to bimmerlink correct?

If it's one of these yes, if not no.

Does that seem like the likely cause? My old Japanese mechanic is at a loss. Even swapping a genuine battery, it needs to be coded or it’s just like a dead battery?

Is there no GR Garage near you to take the car to?

for the last week the car is stuck. It’s in Park and too low to tow with the rear skirts. They haven’t been able to raise the car as they’ve been busy to manually put in neutral. If they do that, then we can push it to the lift and swap the exhaust. After that Toyota will look at it. A GR garage I don’t think so. Thanks for everyone’s insight.
