DTC B1476/76 A/C Inverter Load System Malfunction

DESCRIPTION

DTC Detection Condition:

The compressor assembly stops compressor control and outputs DTC if the rotation load is too great or too small while controlling motor rotation in the compressor assembly.

Possible causes are refrigerant gas leakage, overcharged refrigerant gas, insufficient cooling because of a condenser fan circuit malfunction, or compressor lock.

NOTE: This circuit uses both CAN and multiplex communication. Before performing the inspection, check that the CAN and multiplex communication systems are functioning normally.
