P0BCC OBD Error Code: Problem & Solutions

<<See All OBD Codes

What does P0BCC error code mean? What does this error code signify? How can this error code be removed from the vehicle? Are you confused looking for a solution? Proceed reading the article further. The failure of the inverter is generally known as the generator inverter temperature sensor circuit. This error code – P0BCC will get stored in the vehicle if an issue is found within the generator motor high voltage inverter

The temperature of the generator inverter is found out with the help of temperature sensor by the MG ECU which is placed in the inverter with converter assembly that is inbuilt into the generator inverter. In order to prevent the overheating of the generator inverter, the MG ECU will reduce the inverter output if there is a necessary. Any defect in the sensor is detected by the power management control ECU (HV CPU) depending on temperature sensor values. The inverter with converter assembly will also find out the issues in the generator inverter temperature sensor as well as its wires.

What causes this problem with the Generator Inverter Temperature Sensor Circuit?

• Defective inverter with converter assembly.
• The inverter with converter assembly harness might have an opening or short circuit.
• The inverter with converter assembly circuit might have a weak electrical connection.
• Faulty inverter cooling system.
• Improper functioning of the cooling fan system.
• Inverter water pump assembly might be defective.

1. Inverter Cooling System - Is the inverter cooling system damaged? Are you looking for a replacement for your faulty inverter cooling system? Find them at Parts Avatar at the best prices online.
2. Auto Cooling Fan - A blown auto cooling fan is another symptom of a potential problem with the cooling fan motors. The blown fan must be replaced instantly so that the P0BCC error can be avoided.
3. Inverter With Converter Assembly - The broken inverter with converter assembly has to be fixed so that the P0BCC error code does not get stored and the vehicle functions normally.
4. Inverter Water Pump Assembly - A damaged inverter water pump assembly needs immediate replacement so that you can avoid the P0BCC error from getting stored.
5. Inverter Temperature Sensor - Carefully inspect the inverter temperature sensor for any damages or possible faults. If you find it defective, change it as soon as possible.
6. Engine Control Module - Performance issue may arise in your vehicle if the ECM is defective. Replace the defective ECM by shopping for a new one from Parts Avatar.
7. Powertrain Control Module - Illumination of the check engine light is a common symptom of faulty PCM. Change it immediately.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0BCC here:

Common Symptoms

• The service engine warning light or else the engine light will stay on.

Here are some ways with the help of which you will be able to correct the OBD Code P0BCC.

• Replacing the broken inverter temperature sensor.
• Changing the cooling fan that is damaged.
• The inverter with converter assembly and inverter water pump assembly needs replacement.
• The inverter cooling system has to be fixed.

Here are some steps which you should follow in order to diagnose this fault code:

• The P0BCC diagnostic trouble code is not very difficult to diagnose or carry out.
• If this error code appears in your vehicle it is always best to have a qualified technician or mechanic to look at this error code, where he will use a scanner to find out the problem.
• With the help of a scanner, the mechanic will recover every of the stored codes and freeze frame data by connecting it to the diagnostic port of the vehicle.
• Initially, the mechanic will begin by checking the inverter cooling system and the inverter temperature sensor as it can cause issues in your vehicle.
• Also, they can be one of the reasons if the error code is stored in the vehicle.
• After this, the mechanic will look after the components like cooling fan system, inverter with converter assembly, inverter water pump assembly, for any damages and defects.
• Necessary repairs will be carried out if they are defective.
• Finally, the engine control module or the powertrain control module will be inspected for any damages.
• Once every diagnosis and repairs are properly done, it is very important to retest the code and test drive the vehicle to see if the error codes, still appear and if the engine light keeps blinking.

Common Mistakes When Diagnosis the P0BCC Code

• An issue with the electrical wires.
• Defective inverter.
• Damaged inverter temperature sensor
