P0C10 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0C10 can be defined as Drive Motor "B" Inverter Power Supply Circuit High. The power inverter module is also known as the drive motor generator power inverter module. It has two motor control modules and the hybrid powertrain control module. Every motor control modules works in its respective drive motor generator depending upon hybrid powertrain control module commands. The speed, direction and output torque of its respective drive motor generator is controlled by the motor control modules through the sequencing actuation of high current switching transistors called insulated gate bipolar transistors. Every drive motor generator work utilizing 3 phase AC. The insulated gate bipolar transistor works a single phase of the drive motor generator. Each and every phase is specifically identified as U, V and W. The temperature of each phase is monitored by the motor control modules so that it can detect power inverter module over temperature conditions.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P0C10 error code. The drive motor "B" inverter power supply circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the drive motor "B" inverter power supply circuit would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Drive Motor "B" Inverter Power Supply Circuit High?

• The drive motor ‘B’ inverter might be flawed
• Drive motor ‘B’ inverter harness is not shut or tiny
• Drive motor ‘B’ inverter circuit poor electrical connection

1. Generator Assembly - Some common symptoms of bad generator assembly are weak or dead car battery, weird smells and the warning light on the dashboard might start illuminating. It would be nice if you get it replaced on time.
2. HVAC Blower Motor Control Module - If there is a failure in the blower motor resistors’ internal components, then it might cause the HVAC blower motor control module to malfunction, or it might not function at all on one or more of the settings. Get it replaced before the situation gets worse.
3. Motor Assembly - One of the most common causes of the failure in the motor assembly can be due to neglecting oil changes. Remember that oil is the lifeblood for engines. You can always rely on us as we have best auto parts for our customers.
4. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
5. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
6. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.

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

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the damaged drive motor "B" inverter and its components for error. It the mechanic finds the fault in the connectors in relation to the battery, replace it immediately.
• Some smoke or steam might start getting emitted from underneath the car hood. The ignition timing could be set wrongly and there would be a need to adjust it properly. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced.
• IParts or components should not be replaced with reference to only a P0C10 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P0C10 Code

• There can be some faults in the drive motor generator power inverter control module
