Resetting the Dodge PCM

Some jobs can easily be done at home. All you need is a little guidance. Resetting the powertrain control module (PCM) is one of those tasks.

So what exactly is a PCM? A PCM is basically an ECU or electronic control unit that is commonly used in a motor vehicle. Most of the time, the PCM is a combination of an engine control unit or ECU and the transmission control unit. The PCM controls more than five operations on a truck or car.

Take the case of the PCM in a Dodge Durango. You will find the PCM on the passenger side or on the right side of the engine. This is the SUV’s circuit board computer and it has been designed to withstand extreme weather changes.

The various components of the transmission, engine, powertrain, and other functional areas transfer information to the PCM. If a malfunction is detected, the error indicator on the instrument panel turns on.

The point in question here is whether and when the Dodge PCM needs to be reset, if at all.

This is how the Dodge PCM restarts. Once the hood of the car is opened, you will see the battery inside. You will need to disconnect the negative black wiring terminal from the battery. Put the ignition in the start / on state for half a minute and then put the ignition back in the off mode. Connect the negative battery terminal. Close the hood and then start the vehicle and let it idle. Now check the status of the error light on the instrument panel.

There are other methods to reset the Dodge PCM. You need to scan and clear the error codes that acted as triggers for the malfunction light. There are some special tools for this purpose, such as the scan tool or the code reader-eraser. These tools are not readily available.

In addition to this, after the battery has been disconnected and the PCM has been reset, the PCM will need time to relearn. This is what Dodge mechanics and technicians have been debating about.

Whether the PCM has been rebooted or not; the PCM has to relearn. The time it takes to reset and relearn versus the time it takes to replace the component and relearn is approximately the same. Therefore, the only time the PCM needs to be reset is when the component that set the error code is repaired or replaced. Otherwise, the same component will activate the malfunction indicator light on the dash.

If you need to replace your Dodge PCM computer by truck, truck, or car, there are several online stores where you can pick up what you need. Be sure to read the fine print before signing up for a PCM or any other party. You can get a high-quality remanufactured PCM computer at much better rates than those offered by dealers. Most stores offer a lifetime warranty on these remanufactured PCM computers. In this way, you can replace and drive.
