ESP-A028
ESP_a028_FrLWSSMaxSpeedExceeded
What does ESP-A028 mean?
Tesla alert code in the Electronic Stability Program (ESP) module. Maximum wheel speed reached. Range monitoring for WSS signal which monitors non-plausible high wheel velocity. Range monitoring for WSS signal which monitors non-plausible high wheel velocity Wheel signal has to be below non-plausible high frequency for 2.5 seconds. Will disable VDC/TC and degrade ABS Longitudinal Acceleration Sensor: Adjustment not possible (Offset too large) Inertial signal failed plausibility/integrity checks Inertial messages are present/valid on the bus. Review RCM/DI alerts for other indicators of failure Lost Communication with VCFRONT Control Module: Message Timeout Short circuit of the WSS_FL sensor line to 12V. Short circuit of the wheel speed sensor line to + voltage. Check WSS connection for short circuit and repair/replace harness or sensor Lost Communication With Brake Booster -iBooster: Message Timeout
