1. What does BMS_a069 mean?

BMS_a069 means the vehicle has detected that the high-voltage battery does not have enough energy remaining to support driving. Charge the vehicle now.

2. Technical explanation

Tesla owner-manual material submitted to NHTSA describes BMS_a069 as “Battery charge level low Charge now.” The alert indicates that the high-voltage battery does not have enough energy remaining to support driving. The supplied evidence says this alert is usually present because battery charge has been reduced through normal operation. It also states that the vehicle will be unable to drive or continue driving unless it is charged.

3. What system is affected?

High-voltage battery charge level.

4. How serious is this code?

The database severity is unknown. However, the verified owner-manual evidence states that insufficient high-voltage battery energy remains to support driving and instructs the driver to charge now.

5. Symptoms you may notice

  • The touchscreen displays BMS_a069: “Battery charge level low Charge now.”
  • The vehicle has detected insufficient high-voltage battery energy to support driving.
  • The vehicle may be unable to drive or continue driving unless it is charged.

6. Possible causes

  • The high-voltage battery charge level has been reduced through normal operation.
  • Other causes are not yet established by verified evidence.

7. Can I still drive the vehicle?

No definitive database drive-status value is supplied. Verified owner-manual evidence states that the vehicle will be unable to drive or continue driving unless it is charged.

8. Can I charge the vehicle?

The database charge-status value is unknown. The alert itself instructs the driver to charge now, and the verified owner-manual evidence states that charging is required for the vehicle to drive or continue driving.

9. What you can safely do

  • Charge the vehicle now.
  • While the alert remains present, keep the vehicle charged to 30% capacity or higher to avoid a discrepancy between the touchscreen’s estimated range and the actual high-voltage battery charge level.
  • Use the vehicle’s current high-voltage battery charge level rather than relying solely on estimated range while this alert remains present.

10. Step-by-step troubleshooting

  1. Check the vehicle’s displayed high-voltage battery charge level.
  2. Charge the vehicle.
  3. After charging, observe whether the alert remains present. Further diagnostic steps are not yet established by verified evidence.

11. When to contact service

Service requirement is unknown in the supplied database. If the alert remains after charging or the vehicle cannot be charged, contact Tesla service; the appropriate service diagnosis is not established by verified evidence.

12. What the service center may check

  • Not yet established by verified evidence.

13. Possible repair or resolution

  • Charge the high-voltage battery. No component repair or additional resolution is established by the supplied verified evidence.
