Try a jumper box…

Make sure your jumper box has at least 14.6 volts. If it doesn’t start, it’ll need to be towed most likely…

You can’t just replace the battery yourself, it needs to be programmed…

Also, in the future, lock your car every time you shut it off OR push and hold down the radio power button until the computers shut off…

@NewSupraOwner a standard battery charger won’t do a thing for that battery, not overnight, not ever! If you can’t start it from UNDER THE HOOD, then you must’ve popped a fuse or something. I had to charge my jumper box 100% before it would start the car from under the hood. I don’t care if you...

You have to have a powerful jumper box and it will start FROM UNDER THE HOOD CONNECTION! DO NOT TRY TO JUMP IT FROM THE BATTERY!!!!!!!!!!!!!!!!!!! It will drive after you start it, you’ll get flickering dash, every CEL all that shit. Drive it to the dealership and let them do their thing, trust...

I just went thru a battery nightmare! My advice, drop it off to the dealership and let them do their thing…

switched the JB4 to map0 disabled and yeah, it’s DEFINITELY working! That custom tune is titts!

Let’s see some pics!

What about “TMAP signal active with engine off”? Any idea what that means?

I think I’m just going to have my Supra tech hook it up to their “special” diag tool to see what’s up…this is kinda weird. I wonder if my JB4 is even working? I’m going to change it back to factory map on the way home and see if the car is less powerful. My wife recorded the sport display and it...

I unplugged the below pic connector and started it. I didn’t get a code. then I additionally unplugged one below and got the following codes

@MYA90SUPRA you mean unplug it and then start the car? I didn’t, I can tho if you think it’ll mess anything up?

I appreciate that, I treat people like they’re my friends and family members!

@zrk yes they do, I’m hoping it’s a bad sensor…I did have the connection on the charge pipe, so I guess I couldn’t over heated it and fried the wires?

CEL, I actually found it on bmwfault.codes. If the new sensor doesn’t fix it I guess I’ll have to look into wiring?

@Last Lemming I don’t like how a lot of dealerships are conducting business right now either, all I’m saying is, it’s in poor taste to blast an industry as a whole based on the bad ones. My opinion of course..

There are a lot of dirtbags in the auto industry, I deal with that issue on a daily basis! All I’m saying is don’t be so quick to judge an entire industry based on your local dealership experience. And my friend, I can tell you have absolutely no idea what we’ve been thru, so don’t speak on...

Anyone know about this?

@Last Lemming ,I sell cars and I don’t mark up prices, I don’t play stupid games. I ask what you do for a living because anytime someone calls me a dirtbag for what I do, I like to know what you do as I’m sure in your field of work not everyone is a good person. I’m sure you’re a good person...
