This is a research summary of a manufacturer communication, not a diagnosis for your car, a DIY repair procedure or confirmation of warranty or recall eligibility. No qualified technician has approved a repair for your individual vehicle here.
This historical communication is conditional. The current revision, VIN/build eligibility, measured diagnosis and any warranty or recall decision are not established here. Ask the manufacturer or a qualified shop to check the complete current document.

What prompted this manufacturer document
- MIL or wrench
- Possible discharged 12V battery
- Possible Stop Safely Now message
- The early-build bulletin provides an HVBJB replacement and BECM programming route for the stated fault pattern; it is not interchangeable with the later software-only scope.
Which vehicle conditions must be checked
Each row below retains its own conditions. Do not combine engines, years or models across rows to create new applications. A listed model is not proof that a particular VIN is affected.

Codes recorded in this document
A root listed only as an appearance has no separately verified meaning here. Preserve every suffix and module name; a shared root does not transfer a repair branch to another vehicle.

What an owner can record safely
- Exact stop message
- Build date and drivetrain/GT configuration
- Whether the vehicle has lost propulsion
Editorial safety boundary for this system
Do not continue driving with loss-of-propulsion, isolation or serious battery warnings; obtain model-specific roadside guidance.
- Use current model-specific service information, calibrated equipment and a qualified technician for the selected diagnostic branch.
- Do not open the traction pack, touch orange cables or damaged connectors, bypass interlocks, or perform home insulation testing.
This is a conservative editorial policy, not a manufacturer safe-to-drive decision for a specific vehicle.
What the source does not prove
- Do not treat a low 12V battery as the only fault or offer high-voltage junction-box DIY replacement.
- A code or message alone does not establish a failed part, a safe-to-drive decision or an approved repair for this VIN.
- A service bulletin is not automatically a recall or free warranty repair. Confirm current eligibility directly.
Questions for the repair shop
- Which current manufacturer procedure, VIN/RPO/build gate and test result determine the diagnostic branch?
- Does a later revision or a current recall change the source's original advice?
- What measurement or inspection confirms the cause, and how will the repair be verified?
