Air Conditioning System

DTC 71 A/C INVERTER HIGH VOLTAGE POWER RESOURCE SYSTEM MALFUNCTION

CIRCUIT DESCRIPTION

Detection Item:

The A/C inverter assembly monitors the power voltage from the main battery in the self circuit. It stops compressor control and outputs the DTC when the monitored voltage is outside the specified range. The output DTC is memorized as previous trouble. Compressor control may not resume unless the power switch is turned off.

HINT: The hybrid control system and air conditioning system output DTCs separately. Inspect DTCs following the flow chart for the hybrid control system first if any DTCs from those systems are output simultaneously.

NOTE: The A/C inverter is integrated with the inverter assembly. It is necessary to replace the PCU box assembly if the A/C inverter (inverter assembly) needs to be replaced because the A/C inverter (inverter assembly) cannot be replaced alone.
