Hello,
I bought salvaged tesla model 3 2021 last month but the battery is from different car. As the battery for the car I bought already sold. I manage to disassemble from the put it back in the garage for some fun and education to my boys 12 and 8.
The battery is not able to charge. As I understand I need to make the vehicle to update the latest firmware from all different components by pressing firmware update. It doesn't allow me to update because the battery 0%. The battery is good 360VDC I measured. However, the contactor never click in that cause battery 0%. I measure the contactor control voltage from right body controller 0VDC so the control board not allow to close the contactor. (Maybe due to vehicle configuration mismatch).
Do you have any idea how to get the vehicle firmware update?
Can I need to use Tesla toolbox 3 to deploy the firmware?
Does it work by supplying 12VDC to close the contactor (bypass BMS) to get the battery status above 0% so I can upgrade the firmware online?
Many thanks in advance for you advice. We are now a bit stuck.
Best regards,
Me and my boys.
