P0A94: Understanding The Hybrid Battery Cooling System Fault
The P0A94 fault code refers to the performance of the DCDC converter in the vehicle’s hybrid system. The boost converter, which contains an Intelligent Power Module (IPM) with an Insulated Gate Bipolar Transistor (IGBT) and a reactor, is responsible for boosting the high-voltage direct current to approximately 500 V. The inverter then converts this boosted voltage into alternating current for driving the MG1MG2.
When the MG1MG2 operates as a generator, the inverter converts the alternating current back into direct current.
The boost converter also drops the voltage to charge the HV battery.
The HV control ECU uses voltage sensors in the boost converter and inverter to detect the voltage before and after boosting. Based on these voltage readings, the HV control ECU adjusts the operation of the boost converter to achieve the target voltage. If the DCDC converter is not performing as expected, the P0A94 fault code will be triggered, indicating a potential issue with the boost converter’s performance.
