$0 — charging resolves it in the normal case. If it recurs at 5%+ displayed charge, diagnosis is by Tesla service and cost depends on what's found.
Built for Diesel — Not a Car Reader
ANCEL HD7000 Heavy-Duty Diesel Scanner

A $30 car code reader can't do diesel. The HD7000 reads full-system codes and does parked DPF regen, idle/speed-limit, and service resets from the cab — on everything from a 6.7 Cummins/Power Stroke/Duramax pickup to Class-8 trucks (Detroit, Paccar, CAT, Volvo, Mack, International).

Common Symptoms

  • Alert on the touchscreen: "Battery charge level low — Charge now"
  • Vehicle unable to drive, or unable to continue driving, until charged
  • If it appears while driving, the vehicle needs to shut down (a separate alert should indicate this) and may shut down unexpectedly
  • If it appears while parked, the vehicle may refuse to drive

Probable Causes (Ranked by Likelihood)

  • The high-voltage battery has been discharged through normal driving to the point where it no longer has enough energy to support driving Likely
  • If the alert appears despite a displayed charge level of 5% or higher, a battery or range-estimation issue may be present — Tesla's guidance is to schedule service in that case Possible

Step-by-Step Diagnostic Procedure

  1. Charge the vehicle immediately — per Tesla's official guidance, charging should restore the ability to drive. This alert is usually normal low-battery behavior, not a fault.

  2. If the vehicle has shut down and cannot reach a charger, it will need to be transported (flatbed) to charging — EVs cannot be push-started or fuel-canned like a gas car.

  3. If the alert recurs on later drives even though the displayed charge level is 5% or higher, schedule Tesla service — that pattern suggests the displayed range and actual battery energy are out of sync.

Frequently Asked Questions

What does BMS_a069 mean on a Tesla?

Tesla's official meaning: the high-voltage battery does not have enough energy remaining to support driving — usually simply because the battery has been run down through normal use. The vehicle will not drive (or continue driving) until it's charged.

How do I fix BMS_a069?

Charge the vehicle immediately. In the normal case that fully resolves it. If the alert keeps appearing on later drives even when the display shows 5% charge or more, schedule Tesla service — the displayed range may not reflect the battery's actual energy.

Can my Tesla shut down while driving with BMS_a069?

Yes — Tesla's official text says that if this alert appears while driving, the vehicle needs to shut down, and an unexpected shutdown is possible. Pull over safely and arrange charging or transport to a charger.
