P0613 TCM Processor
OBD-II Trouble Code Technical Description
TCM Processor
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 Chrysler, Dodge, Jeep, Audi, Land Rover, etc.
A stored code P0613 means that the transmission control module (TCM) has detected an internal control processor malfunction.
In some cases, the TCM may be separate from the powertrain control module (PCM). Most frequently, it is integrated into the PCM. This saves automakers space, time, and money.
Each time the ignition is turned on and the PCM is energized, multiple controller self-tests are performed. In addition to running internal controller self-tests, the controller area network (CAN) is used to compare signals from each individual module to ensure that the various controllers are interacting properly.
In monitoring TCM function, if the PCM detects a problem, a code P0613 will be stored and a malfunction indicator lamp (MIL) may be illuminated. Depending upon the perceived severity of the malfunction, multiple failure cycles may be necessary for MIL illumination.

What is the severity of this DTC?
Internal control module codes must always be taken seriously. A stored code P0613 could result in a variety of automatic transmission concerns, including a delayed shift, erratic shifting, or failure to shift.
What are some of the symptoms of the code?
Symptoms of a P0613 trouble code may include:
What are some of the common causes of the code?
Causes for this code may include:
What are some P0613 troubleshooting steps?
Unfortunately, even the most experienced and well-equipped professional technician may find diagnosing a code P0613 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 TCM/PCM power supply codes are present, they will need to be repaired before attempting to diagnose a P0613.
There are several preliminary tests that can be performed prior to declaring any 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 TCM/PCM enters readiness mode, the code is intermittent and will be more difficult to diagnose. The condition, which caused the P0613 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 P0613, information may be your greatest tool. Search your 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. 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 p0613 in the ECU"
In extreme cases, we even have the option to permanently remove the specific DTC p0613 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 p0613.
