HEATING / AIR CONDITIONING AIR CONDITIONING SYSTEM(for HEV Model) B14711C A/C Inverter High Voltage Power Resource Circuit Voltage Out of Range

DESCRIPTION

The hybrid vehicle control ECU monitors the voltage of the HV battery. The hybrid vehicle control ECU stops compressor control and stores this DTC when the monitored voltage is outside the specified range.

This DTC will be stored as a history DTC. Compressor control may not resume unless the ignition switch is turned off.

CAUTION / NOTICE / HINT

CAUTION:: ·

Before inspecting the high-voltage system, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

NOTICE:: ·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

·

When the cable is disconnected from the negative (-) auxiliary battery terminal, the memory of various systems will be cleared. Because of this, be sure to make a record of the contents memorized in each system before starting work. When work is finished, adjust each system to its previous state.

·

The hybrid control system and air conditioning system output DTCs separately. Perform troubleshooting for the hybrid control system first if DTCs for both systems are output simultaneously.

·

The air conditioning system uses the CAN communication system. Inspect the communication functions by following How to Proceed with Troubleshooting. Troubleshoot the air conditioning system after confirming that the communication systems are functioning properly.
