Error Code P0601: What It Means & What To Do?

<<See All OBD Codes

Do you know when the P0601 error code is set in your vehicle? When there is an error identified in the internal control module, then this error code is set. This error occurs in the powertrain control module (PCM) or in other vehicles it takes place in (ECM) engine control module. This error is found by the PCM itself during self-check. The check engine light will brighten and push the vehicle to fail safe mode so as to minimize the damage. The mode will be disabled after the problem is rectified.

P0601 error code means that there is a shorted circuit either in the PCM, wires, or the connectors from the PCM is separated whereas the battery is joint. The main reason for this error code can be either a faulty PCM or the PCM has low voltage.

What causes this problem with the Internal Control Module Memory Check Sum Error?

• The Engine control unit keeps failing or it is already failed.
• The ECU has very low voltage.

1. Powertrain Control Module - The PCM has to function normally in order to avoid this code. If you find the PCM to be faulty, replace them immediately.
2. Internal Control Module - If one or more supporting modules are broken / faulty error will occur in the Internal Control module. Replace the parts if they are damaged.
3. Engine Control Module - There are chances were error in the system can arise due to faulty ECM. Get the right replacement part from Parts Avatar.
4. Check Engine Light - An error in the check engine light will make the engine malfunction. Repair them instantly.

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 P0601 here:

Common Symptoms

• Both the traction control light and ABS is on.
• Starting trouble with engine.
• Vehicle will struggle during running or while running.
• Shift problems with vehicle.

Here are some ways with the help of which you will be able to correct the OBD Code P0601

• This error can be avoided by replacing or reprogramming the PCM. Sometimes the dealers will flash make it working. But in many cases, they are flashed or reprogrammed. When you face this problem it’s good to take it to the dealers.
• You can cover this problem with the help of emission warranty. You can get good help even if you are out powertrain and bumper-to-bumper warranty.
• Sometime people will report the occurrence of code again and again after replacing the PCM. The main reason is most shop replace the PCM whereas they don’t program it. So find a shop where you can reprogram the PCM.
• The seriousness of this code mainly depends on its PCM. It is better not to drive the vehicle if it has extreme drivability struggles or faults.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0601 code to be stored:

• Technicians will start diagnosing the code, by connecting the scan code to the vehicle and checking for codes for some history and existing codes.
• The technician will take care of the freeze frame data and use the information such as engine load, RPM, and coolant temperature to check when the code was set in the vehicle.
• Next step the technician would do is clear the codes and take the vehicles to test drive to see if the code appears again and if the code is set again.
• Next the technician will visually inspect the vehicle and actively check if there are any signs of damages in the circuits, wires and other components that are involved.
• The technician will check if the PCM receives proper voltage with the help of multimeter.
• The last step is to check the PCM. Each vehicle will have its own testing procedures for PCM.

Common Mistakes When Diagnosing the P0601 Code

• Insufficient voltage to the PCM.
• The PCM memory module is damaged.
• The ground circuits of PCM is faulty.
• The output devices that are controlled by PCM is faulty.
