Tesla
Tesla is a leading electric vehicle manufacturer known for its innovative technology, long-range batteries, and over-the-air software updates.
Tesla EV Technology & Diagnostics
Proprietary Battery Management System (BMS) monitors thousands of cells in real time, with dedicated fault codes for thermal runaway, cell imbalance, and coolant loop failures.
Drive Inverter modules (DI/DIF/DIR) control front and rear motors independently — faults here typically indicate power-stage IGBT failures, resolver sensor drift, or firmware version mismatches.
Autopilot System (APS) generates diagnostic alerts for camera calibration, radar signal quality, and neural-network inference errors that may affect driver-assistance features.
Tesla's over-the-air (OTA) update system can resolve many software-related alerts without a service visit, but hardware faults (HV contactors, DC-DC converters) still require physical repair.
