Here’s all you need to know about the OBD code P0C73. At first it may seem quite confusing but with Parts Avatar, we promise to end all your confusions. This OBD-II code high voltage control module failure in technical terms is defined as a motor electronics coolant pump "A" control performance. For the cooling system, the inverter/converter assembly has its own water pump. The power management control module (HV CPU) performs the role of electronically controlling and regulating the water pump. The code P0C73 is set whenever the HV CPU notifies a failure in the water pump.

It should be noted that the power management control ECU (HV CPU) receives the rotation speed information from the inverter water pump assembly. Also, the task of monitoring the speed and detecting the errors is performed by the power management control ECU (HV CPU).

What causes this problem with the Motor Electronics Coolant Pump "A" Control Performance?

• A possible fault inverter cooling system
• The harness inverter cooling system might be open or short circuited
• A weak electrical connection running in the inverter cooling system circuit
• A malfunctioning inverter water pump assembly
• Power management control ECU failure

1. High voltage control module - Love travelling but hate these constant halts? Engine stalling or a dangerous misfiring condition is likely to cause by a defective high voltage control module.

It is essential to diagnose this fault code. Here are some steps which a technician should follow for diagnosing the problem that triggered a P0C73 code to be stored:

The certified mechanic should make use of a device called an OBD-II scanner. Next, this scanner should be connected to the onboard computer inside of the vehicle. It will then retrieve data from the vehicle to determine what issues might be present in the vehicle. The technician will likely first clear the code and then retest the vehicle. If there is an issue, the code will reappear. From that moment, the technician can start to narrow down the actual cause and determine what needs to be done to repair the vehicle.
