Why does the exact Tesla alert ID matter?
Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.
What does BMS-F107 mean?
Tesla fault code in the Battery Management System (BMS) module. A high voltage (HV) battery cell voltage sensor error is detected. There are three reasons for this alert to be reported by the Battery Management System (BMS): BMS_a107_errorType = BMS_A107_MODULEBRICK_MISMATCHThis alerts means that the voltage of the module differs by more than 35mV from the sum of the brick voltages of that module.BMS_a107_errorType = BMS_A107_TVSH_BLEEDV_LOWThis alert type means that the bleed resistor is turned on for that brick, but the voltage is too low (likely due to a stuck bleed resistor).BMS_a107_errorType = BMS_A107_TVSH_IMP_HIGH This alert type is the most common. The system has detected a high impedance on the sensor harness from the Battery Monitoring Board (BMB) to the bricks / module. It means that the measurements from that BMB cannot be trusted.

Affected Tesla Models
What You May Notice
- Red warning light on dashboard: A high voltage (HV) battery cell voltage sensor error is detected. There are three reasons for this alert to be reported
- Vehicle may refuse to drive or charge until the fault is cleared
- Sudden power reduction or shutdown may occur while driving
How to Diagnose and Resolve
- 1 Stop driving immediately and move to a safe location
- 2 Do not attempt to charge the vehicle — active fault: "A high voltage (HV) battery cell voltage sensor error is det"
- 3 Call Tesla Roadside Assistance (+1-877-798-3752) for a flatbed tow
- 4 At the Service Center, Tesla technicians will inspect the HV battery pack and BMS firmware
Severity Notes
BMS-F107 is classified as a Fault, indicating a critical issue in the Battery Management System system. Do not continue driving and contact Tesla Service immediately.
