What does ESP-A103 mean?
Tesla alert code in the Electronic Stability Program (ESP) module. Generic alert for a stability control fault Internal electronic fault detected on ECU. Plausibility failure on reverse gear signal state. Review DI alerts for other failure indicators WSS_RR HET TU buffer noise (enormous amount of edges ocurred). Lost Communication With Drive Motor Control Module B: Message Timeout Brake Pressure Sensor A: Plausibility against second signal failed. Pressure sensor sensitivity is out of specification WSS_FL HET TU buffer noise (enormous amount of edges ocurred).
