ESP_a089_absNoPressureIncrease
What does ESP-A089 mean?
Tesla alert code in the Electronic Stability Program (ESP) module. ABS controler has detected, that there has been no pressure increase for an implausible long time. ABS controller detects that there have been no pressure increases and wheel has not recovered. Returns brake pressure control to driver VDC/TC disabled, possible wheel lock Longitudinal Acceleration Sensor: Plausibility against second signal failed Invalid Data Received From Air Bag Control Module: Alive Counter invalid WSS_FR HET TU buffer noise (enormous amount of edges ocurred). Signal from WSS is noisy/implausible Check connections for short circuit and/or replace WSS
