Stressed? Still see the error code P0C76 flashing? No worries, Parts Avatar to the rescue! Here’s all that you need to know about the error code P0C76.The three-phase bridge circuit which is contained in the inverter, which includes six power transistors (IGBTs) for each of the MG1 and MG2 units. The direct current from the HV battery is changed into three-phase alternating current for generator (MG1) and motor (MG2) by the inverter. The inverter also suitably modifies the three-phase alternating current supplied by generator (MG1) as well as motor (MG2) into direct current for the HV battery. The MG ECU coordinates the disposition of the power transistors (IGBTs). The MG and ECU receive information transmitted by the inverter which is necessary for control such as amperage and voltage.

Well, this OBD-II diagnostic trouble code is referred to as a hybrid battery system discharge time too long in simple terms. It can be seen that at times whenever the high voltage system shuts down, the motor generator (MG) control module (or motor control module depending on manufacturer) emits any residual voltage in the inverter/converter assembly. The code P0C76 displays when the voltage fails to get charged completely (fails to fall within the specifications).

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

• A defective inverter with converter assembly
• Loose or corroded inverter with converter assembly harness
• Inverter with converter assembly circuit fragile electrical connection
• A malfunctioning power management control ECU

1. Converter Assembly - A distorted converter assembly can end up being the chief host inviting the error code P0C76. So, replacing one can be one of the wisest decisions to avoid a problematic system. Apart from this this may also slow down the overall functioning within the system. Tune into Parts Avatar for fixing this issue with the error code P0C76.
2. Converter Assembly Harness - Baffled? Love travelling but hate these halts? Well, it could be due to problems caused by the damaged converter assembly harness. Get your error code fixed instantly with a new converter assembly harness. Parts Avatar right place that provides the best converter assembly harness across the country.
3. Control ECU - Engine stalling or engine performance issues are likely to be caused due to faulty control ECU. not only this, a sluggish engine crank or constant engine stalls may be experienced too. Tune into Parts Avatar if you wish to keep your system safe from all the errors triggered due to a malfunctioning control ECU.
4. Motor Generator - Low coolant temperature alarms, leaks (oil, fuel or coolant) and rise in fuel consumptions is likely to be caused due to a malfunctioning motor generator. Log into Parts Avatar for a new motor generator as soon as possible if you want to save your money and time.
5. Motor Control Module - Complications in starting the vehicle is one the most common problems triggered due to a defective motor control module. Not only this, one is likely to see a low supply of electrical power. Now get your error code fixed instantly with Parts Avatar. We offer the best at the prices you have always wished for.

It is vital 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 P0C76 here:

Common Symptoms

• The engine light illuminated (or service engine soon warning light)

Want to correct the Trouble Code P0C76? Read these points mentioned below:

• In order to perform an accurate diagnosis, first a visual inspection should be performed of all the electrical parts. Repair or replace a damaged inverter with converter assembly
• Mend or restore a power management control ECU as per requirements
• All the corroded or disconnected harness in the inverter with converter assembly should be changed or repaired
• Immediate measures should be taken to fix a poor electrical connection in the inverter with converter assembly circuit

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0C76 code to be stored:

Problems with the battery such as a low or discharged battery or corroded battery cables should be suspected if one observes a clicking noise (when attempting to start) or the engine fails to crank. Also, there is problem with the fuel or ignition if the engine cranks when the car gets started but fails to turn over. A failure of the starter motor relay, a clogged fuel filter, a damaged fuel pump or a failure in the ignition switch are some common reasons that lead to a problem while the engine starts. Also, one should carefully verify the functioning of the VCT solenoid. The VCT solenoid valve can also be stuck due to contamination. It is advised to refer to a vehicle specific repair manual from time to time while performing the component tests for the VCT unit.
