Changing Vehicle Battery

[ToyoBimmer]

If battery is even swap in capacity, amps, etc. no need to program.

In fact, as a life long BMW owner I have never had a car programmed for a replacement battery.

With my Supra i have switched to a Lithium battery and never programmed that!
People do not have a realistic grasp on the process and I guess are willing to part with stealership $


OP, if there is no battery I do not see how alarm goes off?
Battery is clearly dead, if you cannot even jump.

Go buy a replacement and then if (small odds) it is something else you can keep old battery as a backup or something. But is 3+ years old it is likely gone. Especially if you do not drive often and key is stored in proximity to car.

I have put a volt meter on my current battery and it is reading 12.2V, whereas my son’s Hilux (donor battery) reads 12.7V.

When we try to jump it, I get all of the dashboard lights but only a single click sound when I push the starter button.

Then a message on the screen display:

Drivetrain
You can continue driving. Roadside assistance required. Drive power reduced. Please arrange an appointment with your dealer.”

It’s as if the car thinks the engine has started but has put itself into limp mode until you get it to a dealer for diagnostics?

I am really frustrated by this problem and really don’t want to have to get the vehicle towed.

Sounds like you may need a starter.

Nah, just a new battery.

12.2v (~65% SoC) from a 90ah battery should be more than enough to start the car, and it’s a bit weird that it cannot be jumped. Not sure what size the Hilux battery is so I can’t say much there.

There’s a few reports of starter failures in early model cars. Hopefully it is not that… but it wouldn’t be surprising.

Op, you really should pull codes as we’re just guessing here.
