DTC B1473 A/C Inverter Start-up Signal System Malfunction

DESCRIPTION

Detection Condition:

The inverter activation signal is sent to the A/C inverter from the hybrid control ECU. Compressor control is stopped and the DTC is output if there is an open or short in the signal circuit.

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