DTC P0A10-263: DC / DC Converter Status Circuit High Input [12/2014 - ]: Description

Refer to the description for DTC P0A08-264. Refer to DESCRIPTION .

If the hybrid vehicle control ECU detects a malfunction related to the DC/DC converter, it uses the NODD signal line to transmit a stop command to the DC/DC converter. The hybrid vehicle control ECU also receives signals indicating a normal or abnormal condition of the 12 V charging system from the inverter with converter assembly.

If the vehicle is being driven with an inoperative DC/DC converter, the voltage of the auxiliary battery will drop, which will prevent the continued operation of the vehicle. Therefore, the hybrid vehicle control ECU monitors the operation of the DC/DC converter and alerts the driver if it detects a malfunction.
