What does DI-A233 mean?
Tesla alert code in the Drive Inverter (DI) module. Impact detected on a front wheel Drive Inverter Warning: Proximity signal is irrational Drive Inverter Warning: Cruise control CAN node is MIA Drive Inverter Warning: Regen is Limited info from manualDI_A201 The powertrain is limiting regen braking. This can be for multiple reasons: the battery pack is too hot or cold, the battery pack is fully charged, or the battery pack is limiting for another reason. This alert will clear over time The accelerator pedal might behave differently: it will provide less regen braking than normal when the accelerator pedal is fully depressed.
