TAS-A162
TAS_a162_compressorValveOpenGND
What does TAS-A162 mean?
Tesla alert code in the Thermal Architecture System (TAS) module. Ground return wire from exhaust/boost valve block detected disconnected. One or more CAN messages from UI are not being received by the ECU. One or more CAN messages from UI are not being received by the ECU (missing, bad RX rate, or invalid checksum/counter). Successful reception of all RXd CAN messages from UI. Air suspension functionality may be reduced. Pressure sensor signal voltage too high. Pressure sensor signal received is too high. ECU has requested suspension yellow warning lamp to be displayed. ECU has requested suspension yellow warning lamp to not be displayed. Yellow suspension warning lamp will be displayed. Exhaust air valve detected open circuit. Exhaust air valve commanded on but no electrical current measured. Signal to UI to show suspension geofence notification. Suspension height target change due to suspension geofence. Abnormal PWM signal received from rear left PWM height sensor. Internal air spring or air reservoir valve leak detected. Air pressure increase while idle measured over time. No air pressure increase while idle measured over time. Possible decrease in vehicle ride height while vehicle sleeps.
