P0C31 OBD Error Code: Problem & Solutions
OBD Code P0C31 - Inverter "B" Cooling System Performance
The hybrid battery inverter cooling system issue revolves around the
problem of keep the battery under normal working conditions and temperatures. Thus,
when the power management module detects any performance issues with the
cooling system, the OBD code P0C31 will get stored in the system and the
vehicle can go into fail safe mode.

It is important to maintain correct operating pressure for the hybrid
battery to work with its maximum potential. The hybrid battery inverter cooling
system comes into play for this function ad when the PCM detect any problem
with the inverter “B” cooling system, the OBD code will stored in the system.
What causes this
problem with the Inverter "B" Cooling System Performance?
- Inverter “B” cooling system faulty
- Inverter cooling system wiring and connector issues
- Poor electrical connections to inverter cooling system

Replace/Repair These Parts To Fix Code P0C31
- Hybrid Drive Cooling Pump - The cooling pump play a major role in keeping the battery temperatures under control and ensuring proper functioning. If the pump gets damaged, it can lead to increased temperatures that can hamper many starting and charging parts. Thus, replace it immediately, if found damaged.
- Inverter Cooler Pump - The inverter cooler pump maintains a cool environment for the hybrid battery to operate properly. Without the cooler pump working properly, the battery might overheat and malfunction. Thus, if the inverter cooler pump is not working properly, inspect for damages and replace it now!
- Engine Control Module - ECM faults are rare but can be a big problem as faulty ECM will cause wrong vehicle operations and can also result in wrong OBD codes getting stored in the system which can also cause misdiagnosis. Thus, replace faulty ECM components now!
- Powertrain Control Module - Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now

Easy Diagnosis Of Engine Error OBD Code P0C31
It is essential to diagnose this fault code. Here are some steps which a
mechanic should follow for diagnosing the problem that triggered a P0C31 code
to be stored:
- The error code P0C31 can be diagnosed using an OBD-II trouble code
scanner.
- This scanner should be utilized in order to store the freeze frame data
to collect the details of this error code P0C31 by a certified mechanic.
- The mechanic should also check and confirm the presence of any
additional codes.
- Now, if there are a number of codes, they should be aligned in order. It
is essential to treat the codes in the order they have been stored in.
- After all the repairs have been performed, it is recommended to clear
the codes and reset the system to observe if the code persists.
- If the code fails to reappear, it was likely due to an intermittent
issue or was triggered falsely.
- Check for the inverter cooling pump problems that might be physically
damaged, thus leading to inappropriate functioning. Thus, replace the faulty
parts immediately.
- Inspect for power management system related issues and replace the
faulty system component. Also check for coolant pump issue that might be due to
leakages thus causing problematic battery performance.
- Don’t forget to check for damaged wiring and connectors in association
with various components. It is advisable to replace it, if necessary.
- Next, check the ECU and PCM for the faults and replace and reprogram as
required. Although, this problem is rare, but must be properly checked for and
repaired as required.
Common Mistakes When Diagnosing the P0C31 Code
- Quirks in the powertrain control module
- Hybrid motor assembly might start failing
- Inverter cooling system leakage problem
- Coolant water pump issues
- Wiring and connector related issues
