Has anyone substituted the AtlasBX 12V battery without upgrading the outdated firmware?

[Videoman]

I possess a 2018 vehicle equipped with a failing Atlas LV battery. I visited the service centre, and they provided me with a new AtlasBX. The existing service notes recommend updating to version 2023.32 and performing certain actions in the service menu; however, I am still on version 2023.27.12. I am enquiring if anyone has successfully replaced the battery without adhering to the firmware update specified in the instructions. A previous procedure must have occurred; the service menus appear to differ from the current instructions. I wish to refrain from updating the firmware to avoid losing the double/single pull functionality for EAP/FSD.
The majority of YouTube videos do not demonstrate individuals using the service menu.

Replacing the low-voltage battery does not necessitate a firmware update. It may be included in the Service Centre estimate as a favour on occasion. If you choose not to wait for the software update, they can initiate the download, allowing you to install it upon your return home.

I will deactivate the power, unhook the high voltage, and replace the battery. The updated edition of the service manual has several warnings.

The most recent versions feature a Learn New Battery option and the capability to switch between various battery kinds. However, I am merely exchanging the same type, so I believe I should be fine.

The Tesla technician who performed my last service in 2022 replaced it in the parking lot without any software involvement. He detached the PCS connection beneath the rear seat, disconnected the battery, substituted it, and thereafter reconnected the PCS.

I apologise for my lack of knowledge, but have you not updated your software since 2023? What do you mean by not wanting to forfeit your double/single pull for EAP/FSD? Currently, in my 2023 Model 3. The initial draw activates cruise control, while the subsequent pull engages adaptive cruise control (AP). I have the choice in the menu to direct a single draw to AP, but I want the capability to use CC.

Indeed I have not modified it since 2023, allowing me to utilise either TACC or FSD with one or two pulls. When I am in FSD and encounter a pothole, I can disengage FSD, causing the vehicle to revert to TACC. Was it reinstated? I possess an outdated 2018 Model 3 and doubt that the forthcoming improvements will offer any significant enhancements for me.

I conducted some testing on your behalf!

I now possess a 2024 Model 3 including scroll wheel activation for Autopilot/TACC, without FSD, and equipped with the latest software. The Autopilot settings tab offers an activation choice for "Single Click" or "Double Click," analogous to Single Pull/Double Pull on the stalk.


In "Single Click" mode, only Autopilot is engaged, necessitating a modification in settings to activate Traffic-Aware Cruise.

In "Double Click" mode, the initial click engages Traffic-Aware Cruise, while the subsequent click enables Autopilot. The distinction is audible, since TACC produces a singular bong sound, but AP emits a dual-tone startup sound.

This is due to your lack of a stalk. Vehicles equipped with stalks lost the functionality to toggle between TACC and FSD following the update 2023.44.30.x. Vehicles lacking stalks, such as yours, can utilise the scroll button as you indicated. If there has been a modification allowing an individual with a stalk to transition effortlessly between TACC and FSD without halting the vehicle or altering the mode, or establishing a separate driver profile, that would be valuable information. One would assume Tesla would provide an option for vehicles equipped with stalks to utilise the button, but to my knowledge, they have not.

The battery replacement was successful. The replacement was installed, and the alert has disappeared. Avoid tampering with the service menus.

I possess only TACC and Autopilot, not FSD. Prior to November 2024, I possessed a 2018 Model 3, which featured the same setting; I conducted a test to determine if the scroll wheel models also include that setting.

The Autopilot manual similarly stipulates this information:

Approach this information with scepticism. In my 2023 Model 3, equipped with a stalk, I have configured it to activate TACC with a single pull. Subsequently, a double pull for AP; I lack FSD.

An option exists to modify it to a single pull to access AP. I personally prefer not to, as there are instances when TACC is more advantageous for me. The road is excessively winding for my preference, or for any other reason.


However, if you possess FSD, I am uncertain how that would alter the single pull for TACC and the double pull for FSD.
