Performing a Ford PCM reflash is not as complicated as it sounds. There are several tools that you can use to do the job correctly. Depending on the car you own, the tool may be an older GM or Ford model, or it may be an IDS, Tech 2 or Vetronix device. Once you’ve found the right tool for your car, you can begin the process of programming the PCM.
GM
The powertrain control module (PCM) is the computer at the heart of your GM or Ford vehicle. Whenever a component fails, the PCM records this problem and stores the troubleshooting information for the vehicle.
The only way to fix this is to have the powertrain control module re-flashed. However, it is important to remember that you cannot reflash the PCM of a GM or Ford vehicle if you do not have the appropriate software. The only solution is to have a PCM reprogramming tool or to purchase GM software.
When performing a PCM reflash, you must first make sure that the power supply is consistent. Voltage fluctuations can mess up the programming process.
A scan tool for GM and Ford vehicles such as the EASE Diagnostics system is necessary to perform the task. For older vehicles, you can also use an IDS or Ford New Generation Star (NGS) software. But if you are using an unprogrammed service unit (USB), you will need to write the program yourself, and then install it in the car to load it.
Ford
If you’re planning to tune your Ford, there are several methods to do so. One method is to buy a Ford PCM flash tool. It is easy to use, and comes with a trial period. The software also allows you to perform multiple functions. Some of these tools can be found for free, while others require an investment.
The most popular type of Ford PCM flash tool is the Superchips Bluefin, which was a breakthrough in vehicle remapping in 2005. These tools have user-friendly software that can track changes in the software, as well as help you make the correct choice for your vehicle.
GM dealers can use the Tech 1A scan tool, which is part of the Techline Information System 2000. The NGS scan tool is compatible with GM vehicles through 1996, and the Tech 2 tool for the following year’s model year.
This scan tool supports the reprogramming of EEC-V PCMs and other Ford on-board computers. GM provides updated application files on Techline CDs for aftermarket use, while Ford releases new versions of its scanner tools each month.
Chrysler
When you bring your car to your mechanic for a Chrysler PCM reflash, you’re making a significant investment. However, there are several things you need to consider before getting started.
You’ll want to make sure the technician has the correct tools for the job, so you can ensure the reflash process goes smoothly. Before you get started, you should identify your vehicle’s controller type. Then, you can look for information on the specific type of flash your Chrysler needs.
A Chrysler PCM can only be reprogrammed in a certain way if it’s programmed with a new software version, so the procedure must be done by an authorized dealer. The process is fairly straightforward, but it can be costly.
To perform a Chrysler PCM reflash, you’ll need a diagnostic tool that supports reprogramming of powertrain PCMs. The most common tools for this purpose are Ford J2534 and Pass Thru Pro III, but you may need a special programming tool to complete the job.
If your vehicle requires a PCM reflash, it’s time to make an appointment with a Hickok Ford dealer. Dealers can often offer a lower price for the PCM reflash than dealerships can. A technician can diagnose a PCM fault using a scan tool.
During the procedure, a technician will use a Mopar Diagnostic System, which includes a DRB III scan tool and an OBD II connector. The technician will turn on the vehicle and start the process by “auto connecting.” Once the scan tool is connected, the technician will begin the reflash procedure.
Most reprogramming systems will interface with the vehicle’s computer to establish its revision level. The purpose of reprogramming is to correct an issue and should be documented in a technical service bulletin. Unfortunately, such materials are often incomplete or outdated.
Fortunately, there are many sources for updated files, including GM Expertec and Techline CDs. Hickok offers PCM flashing functionality for 1995 Ford vehicles with EEC-V PCMs and other Ford on-board computers.
The cost for a Ford PCM reflash is around $1700, which includes the first year of subscription for a computer downloading service.
However, since it is a new program, the price of renewal is not yet known. Ford and Hickok are in the process of replacing the system that allows them to reprogram the vehicle’s computer. There is another cost, which is not listed here, when the reprogramming system is switched to another company.
The first step in a PCM reflash is to connect the DART to the diagnostic link connector on the vehicle. Once it has the necessary information, the DART stores the information and communicates it to the OTC computer.
After the data link is established, the technician reconnects the DART to the vehicle’s DLC and loads the update into the vehicle. The process takes about 20 minutes. Unlike other car-reflashing services, this method does not require a PC or stack of CDs.
