What does ESP-A199 mean?
Tesla alert code in the Electronic Stability Program (ESP) module. Voltage across pins 25 and 38 on the ESP connector below specification Voltage across pins 25 and 38 on the ESP connector meets specifications More than one suspected wheel speed sensor failures occur at the same time for more than 500ms. A suspected wheel speed sensor failure is set in the following situation: Noise monitoring- slip monitoring- dynamic monitoring- monitoring of absent signal or monitoring of flat tire sets a suspicious flag. Check connection integrity and power cycle, replace WSS if necessary. Lost Communication With Drive Motor Control Module A: Message Timeout ESP CAN - VCFRONT_espLVState message fault
