P0C75 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Wishing to combat the error code P0C75? Don’t know where to start from? Well, we have solution for you! Here’s all you need to know about the error code P0C75. There is a three-phase bridge circuit inside the inverter that further has six power transistors (IGBTs) each for MG1 and MG2. The inverter performs the function of converting the high-voltage direct current from the HV battery into three-phase alternating current for generator (MG1) and motor (MG2). In addition to this, the three-phase alternating current supplied by generator (MG1) and motor (MG2) is also converted into direct current for the HV battery. The actuation of the power transistors (IGBTs) is regulated by the MG ECU. The information which is important for control is transmitted by the inverter to the MG ECU such as amperage and voltage. All the residual voltage in the inverter/converter is discharged by the motor generator (MG) control module (or motor control module depending on manufacturer) when the high voltage system is turned off. The code P0C75 is set whenever the voltage is discharged quickly.

It should be noted that the OBD-II diagnostic trouble code is determined as a hybrid battery system discharge time too short. Also, whenever the high voltage system shuts down, the motor generator (MG) control module (or motor control module depending on manufacturer) releases any residual in the inverter/converter assembly. The code P0C75 sets in whenever the voltage gets discharged.

What causes this problem with the Hybrid Battery System Discharge Time Too Short?

• A damaged inverter with converter assembly
• The inverter with converter assembly harness short circuited or loose
• Inverter with converter assembly circuit might have a weak electrical connection
• Power management control ECU malfunction

1. Converter Assembly - A bad converter assembly can be harmful. It leads dangerous misfiring conditions, overheating and a deteriorating engine performance too. Now get your error code P0C75 fixed right away with Parts Avatar. We are just a click away! Log in now!
2. Converter Assembly Harness - A corroded or disconnected converter assembly harness can be problematic leading to a drain in the functioning of the system. The check engine light is likely to illuminate too. Now get your converter assembly harness delivered right at your doorstep with Parts Avatar. Isn’t it just the perfect deal?
3. Control ECU - Stressed? Can’t figure out the reason behind the problems? Well, a problematic engine control unit can also slowly damage a mass airflow sensor and oxygen sensor too. So if you want to save your hard earned money from being spent on a whole lot of major repairs, get your control ECU repaired or replaced.
4. Motor Generator - Check engine light illuminated? Dimmed headlights? Or electronics installed in the car? Well, all this is caused by a malfunctioning motor generator. Log into Parts Avatar for repairing or mending your system’ motor generator right away
5. Motor Control Module - A failed motor power switching and amplification in electric variable-speed and servo drive is likely to follow a malfunction in the motor control module. So if you want to save your time and money, we advise you to change your motor control module right away to avoid further problems caused by the error code P0C75.

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 P0C75 here:

Common Symptoms

• Often, the engine light turns on (or service engine soon warning light)

Here are some ways with the help of which you will be able to correct the OBD Code P0C75

• First of all, a thorough visual inspection should be performed all all the electrical components. Repair or replace a faulty inverter with converter assembly
• Change or mend a defective power management control ECU
• Restore or repair a corroded or open harness in the inverter with converter assembly
• Measures should be taken to fix a poor electrical connection in the inverter with converter assembly circuit

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade converter assembly, converter assembly harness, poor electrical connection, control ECU, motor generator, motor control module, assembly converter, torque converter hybrid battery system parts and a lot more for our precious customers.

Here are some steps which you should follow in order to diagnose this fault code P0C75:

To start the diagnosis, the first essential step of the technician should be using a scanner (or code reader) and a digital volt/ohmmeter as these will be helpful in successfully diagnosing this code-storing condition. Next, it is essential to you diagnose with a visual inspection of system wiring, connectors, and components. It is recommended to restore or mend any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful. If the system wiring, connectors, and components appear to be in normal working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data. Also, repair or replace system circuits/connectors as required and retest the system to ensure that repairs were successful.
