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 DI-A210 mean?
Tesla alert code in the Drive Inverter (DI) module. Drive Inverter Warning: Inputs to stability control have degraded The actuators required for stability control are in degraded states, so stability control is also degraded. Check tractionControlState and espActuatorState to find the specific controller that is degrading stability control. For tractionControlState, check previous DI alerts that point to specific cause of their degredation. For espActuatorState, check for ESP alerts that point to the specific cause of its degredation. This alert will clear on the drive cycle after the root cause has been corrected. Traction control and stability control may fault due to this error. The vehicle should be driven with extreme caution if these sytems are faulted. Drive Inverter Warning: UI (User Interface) node is MIA on CAN for one or multiple messages Drive Inverter Warning: Brake torque signal error Drive Inverter User Alert: Front Motor Mode selected by user Drive Inverter Warning: High stack usage detected Drive Inverter Warning: Driver Assistance ECU is MIA Drive Inverter Warning: ECC Protection detected flash fetch or RAM read error Drive Inverter User Alert: Car is plugged in and cannot drive

Affected Tesla Models
What You May Notice
- DI-A210 may appear with another Tesla alert in the Drive Inverter (DI) system.
- The vehicle may limit charging, driving, comfort, or safety features depending on the active alerts.
- The alert may clear after sleep, but recurring alerts should be treated as service-relevant.
How to Diagnose and Resolve
- 1 Reboot the vehicle (hold both scroll wheels)
- 2 Check for pending OTA software updates
- 3 Monitor for recurrence over the next few days; schedule service if needed
Severity Notes
DI-A210 is an Alert in the Drive Inverter system. Confirm the vehicle screen and Tesla app show no driving or charging restrictions, and schedule service if the alert returns.
