HVP_w028_PackVoltMismatchFault
What does HVP_w028 mean?
Tesla warning code in the High Voltage Protection (HVP) module. Warns if the pack voltage doesn't match approximately with sum of brick voltages The pack voltage doesn't match approximately with sum of brick voltages The pack voltage match approximately with sum of brick voltages The contactors may not be allowed to close Alerts if PyroLeakTest pyro diagnostic has cross warning threshold PyroLeakTest sees an Aout outside of 15% tolerance when measuring leakage Customer Facing text to seek service immediately Warns if the BMS node is mia on HVS CAN The BMS node is mia on HVS CAN The BMS node is not mia on HVS CAN Warn if FC contactors are forced open
