|What Does the B1475 Lexus Code Mean?

The A/C inverter in the A/C Inverter Assembly monitors the cooling water temperature with the temperature sensor. It stops compressor control and outputs the Diagnostic Trouble Code (DTC) when the monitored temperature is outside specified range (too high or too low). The hybrid system and the air conditioning system monitor the cooling water temperature separately. If DTCs referring to an inverter cooling system malfunction are output simultaneously, there may be trouble such as insufficient cooling water. If DTCs are output only for the air conditioning system, there may be an open or short in the temperature sensor circuit in the inverter. The OBDII code set when the cooling water temperature in the inverter is outside the specified range (temperature is too high), or there is an open or short to ground in the temperature sensor circuit.
