TAS-A075
TAS_a075_underVoltage5VOffBoard
What does TAS-A075 mean?
Tesla alert code in the Thermal Architecture System (TAS) module. Off board 5V switched supply is measured to be under 4.5V. Static vehicle spring leak check detected a spring leak on the rear right air spring. Rear right air spring leak was detected with vehicle static. Abnormal PWM signal received from rear right PWM height sensor. Implausible condition detected on exhaust air valve circuit. Implausible condition detected on exhaust air valve circuit, possibly due to ECU hardware failure. Implausible condition detected on rear right air valve circuit. One or more CAN messages from RCM are not being received by the ECU. One or more CAN messages from RCM are not being received by the ECU (missing, bad RX rate, or invalid checksum/counter). Successful reception of all RXd CAN messages from RCM. Air suspension functionality may be reduced. Excessive leveling corrections may occur. Air suspension may not disable if a vehicle crash occurs. Exhaust air valve detected short circuit. Exhaust air valve output shorted to ground or battery voltage. Boost air valve detected short circuit. Boost air valve output shorted to ground or battery voltage.
