P060C Internal Control Module Main Processor Performance
OBD-II Trouble Code Technical Description
Internal Control Module Main Processor Performance
What does that mean?
This generic powertrain diagnostic trouble code (DTC) typically applies to many OBD-II vehicles. That may include but is not limited to vehicles from Fiat, Ford, Mazda, Lincoln, Chevy, etc.
When a code P060C is stored, it means that the powertrain control module (PCM) has detected a main processor performance error. Other on-board controllers may also detect a PCM main processor performance error and cause a code of this type to be stored.
The internal control module monitoring processors are responsible for various controller self-test duties and overall internal control module accountability. Internal controller (especially PCM) temperature, as well as multiple input and output signals are constantly monitored by specific controller processors.
Whenever the ignition is on and the PCM is energized, numerous internal controller processing self-tests are initiated. In addition to running internal controller self-tests, the controller area network (CAN) also compares signals from each individual module to ensure that each controller is functioning properly. These tests are performed simultaneously.
If the PCM detects a discrepancy between any of the on-board controllers, which would indicate an internal processor error, a code P060C will be stored and a malfunction indicator lamp (MIL) may be illuminated. Multiple failure cycles may be necessary for MIL illumination, depending upon the perceived severity of the malfunction.

What is the severity of this DTC?
Internal control module processor codes should be categorized as severe. A stored code P060C could result in a no-start condition or serious drivability issues, suddenly and without warning.
What are some of the symptoms of the code?
Symptoms of a P060C trouble code may include:
What are some of the common causes of the code?
Causes for this code may include:
What are some P060C troubleshooting steps?
Even to the most experienced and well-equipped professional technician diagnosing a code P060C can prove to be quite a challenge. There is also the issue of reprogramming. Without the necessary reprogramming equipment, it will be impossible to replace a defective controller and complete a successful repair.
If there are ECM/PCM power supply codes present, they will obviously need to be rectified before attempting to diagnose a P060C.
There are several preliminary tests that can be performed prior to declaring an individual controller defective. A diagnostic scanner, a digital volt/ohmmeter (DVOM), and a source of reliable vehicle information will be required.
Connect the scanner to the vehicle diagnostic port and retrieve all stored codes and freeze frame data. You will want to write this information down, just in case the code proves to be an intermittent one. After recording all pertinent information, clear the codes and test drive the vehicle until the code is reset or the PCM enters readiness mode. If the PCM enters readiness mode, the code is intermittent and will be more difficult to diagnose. The condition, which caused the P060C to be stored, may even need to worsen before a diagnosis can be made. If the code is reset, continue with this short list of preliminary tests.
When attempting to diagnose a P060C, information may be your greatest tool. Search you vehicle information source for technical service bulletins (TSB) that parallel the code stored, vehicle (year, make, model, and engine), and symptoms exhibited. If you find the right TSB, it may yield diagnostic information that will aid you in a major way.
Use your source of vehicle information to obtain connector face views, connector pin-out charts, component locators, wiring diagrams, and diagnostic flow charts related to the code and vehicle in question.
Use the DVOM to test controller power supply fuses and relays. Test and replace blown fuses as required. Fuses should be tested with the circuit loaded.
If all fuses and relays appear to be functioning as intended, a visual inspection of controller related wiring and harnesses is in order. You will also want to check chassis and engine ground junctions. Use your vehicle information source to obtain ground locations for related circuits. Use the DVOM to test ground integrity.
Visually inspect system controllers for signs of water, heat, or collision damage. Any controller that is damaged, especially by water, should be considered defective.
If controller power and ground circuits are intact, suspect a defective controller or a controller programming error. Controller replacement will require reprogramming. In some cases, you may purchase reprogrammed controllers through aftermarket sources. Other vehicles/controllers will require on-board reprogramming that may only be done through a dealership or other qualified source.

"Delete Error Code Permanently, Disable DTC Error Code Function for p060c in the ECU"
In extreme cases, we even have the option to permanently remove the specific DTC p060c and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.
Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p060c.
