How Do You Update The Ford Pcm Software

How Do I Reflash My Contrivance PCM? (Updated)

Before nosotros swoop right into the how-to department, let's kickoff with the basics. We'll exist covering when you lot should consider powertrain control module (PCM) or electronic command module (ECM) reflashing, how it works, what tools yous need, and how to be sure this is a DIY project you want to tackle yourself.

What is Powertrain Control Module Reflashing?

Powertrain Command Module reflashing is the process of replacing the existing software in a vehicle controller with new software. This is done by electronically transferring approved calibration files from a vehicle manufacturer's website. This process is as well known as ECM reprogramming, flashing, reprogramming, programming or reconfiguring.

You could compare reflashing to demolishing a firm, and so edifice another house (according to the exact same blueprints) in its place. It will wait the same, just the structure materials volition be new and it won't announced like it has been lived in earlier. Plus, it will contain all the latest improvements.

Why Would I Want To Reflash My Contrivance Powertrain Control Module?

There are several reasons why you might desire to reflash your Dodge Powertrain Control Module.

– The vehicle is showing false problem codes.

– The original manufacturing plant PCM programming might be overly sensitive or not accept into account wear or other factors that may bear on the performance of private sensors or the OBD 2 monitors.

– Y'all need to resolve a hot or cold starting event, idle roughness, stalling, or an emissions failure.

– You may want to change the engine idle speed, spark timing, fuel mixture or other emission command functions.

– Y'all want to shine out or alter the shift characteristics of an automatic transmission.

– You lot need to modify the functioning of the ABS, traction command or stability command systems.

If your machine has been having problems whose root causes are difficult to observe, more often than not it will have something to practise with the computer system.

What if I have an older Dodge (1993 – 2003)?

While newer vehicles come with standard applications set up for owner use, older automobiles with PCM modules crave code sourcing. If you accept a Contrivance vehicle manufactured betwixt 1993 and 2003 and plan to install new or aftermarket sensor units, your power control module (PCM) may non recognize the new equipment. The sensors from the new equipment are sending information that'southward coded in a way that the module cannot understand.

Fortunately, most of the PCMs installed during that time contain a Program Read But Memory (PROM) bit that can either exist replaced or reflashed to accept information from nearly any model of Contrivance vehicle.

What Tools You Need to Perform a Powertrain Control Module Reflash

Current owners of Dodge vehicles congenital and sold before 2004 tin perform their own PCM reprogramming, but they demand some specific equipment on hand besides as a digital programme that is used to convey information to the module. PCM flash tools include:

i.Tech 2 scan tool ( or pass-through reprogramming device) – Look for one that is J2534 compliant.

2. Reliable cyberspace connection – Use a Windows desktop or laptop for downloading the wink software from the vehicle manufacturer's website. If your Wi-Fi is unstable, apply a LAN/ethernet connection.

3. Subscription – The proper scale software can be downloaded from the Internet in Wink version after the vehicle owner has purchased the TIS subscription. On GM vehicles, a listing of wink updates that are available can be found on GM's Vehicle PCM Scale Information website. You'll demand to enter your 17-character Vehicle Identification Number (VIN).

4.Cables – You'll need a cablevision to connect the PC to the scan tool or J2534 pass-through device, and a cable to connect the browse tool or J2534 pass-through device to the OBD II connector on the vehicle.

How to Perform a Powertrain Control Module Reflash

1. Obtain the proper calibration software from GM and download to your PC.

ii. Connect your PC to the Tech 2 scan tool with an RS232 cablevision pass-through device.

3. Before you starting time the procedure, make sure the battery is fully charged.

4. Start the GM recalibration software program on your PC and enter the vehicle information (yr, make, model, etc.).

5. Connect the Tech 2 scan tool to the diagnostic connector on the vehicle (located under the nuance near the steering column).

vi. Switch the Tech 2 browse tool on and expect for the Starting time screen.

7. Enter the vehicle VIN.

8. Choose the operating system, engine, fuel organization, speedometer or transmission.

9. Select "normal reprogramming" or "VCI" (special modifications).

x. Choose the update message/recalibration number from the bill of fare.

eleven. Get-go the transfer of data. Every bit the software is loaded, you will meet a progress bar. The reprogramming procedure usually takes thirty-40 minutes.

12. When the software has finished loading, it will note that programming is complete. The data is then transferred to the PCM's memory bit.

13. Plow off the ignition, then disconnect the browse tool.

Troubleshooting Powertrain Control Module Reflashing

Admittedly, PCM reprogramming doesn't e'er go smoothly. Even experts report that sometimes the PCM will reprogram correctly merely some other control unit will not, causing the whole operation to stall or abort. Sometimes information technology takes multiple attempts to complete the operation. If the programming seems to stall, the tool visitor'due south technical support line can be an essential resource.

There are a few mutual issues that can arise during the process:

– Cablevision connections get loose

– Loss of power to the browse tool

– Loss of internet connectivity

– PC crash

– Turning off the ignition before the procedure is complete

– Depression vehicle battery voltage

Throughout the reprogramming operation, battery voltage must remain constant. Sometimes the job goes apace and a jumper pack will provide enough extra power. If the job takes an hour or more, even the slight AC ripple produced by a standard battery charger is enough to cause a trouble. Some battery chargers are made to provide clean voltage for reprogramming.

When shopping, look for electronically controlled battery chargers and power supplies that mention reprogramming or reflashing. If the battery voltage falls too depression during that first kickoff-upward, the PCM may not initialize correctly.

Information technology's important to note that the GM setup will not allow the same scale to be reinstalled over itself. Only an updated calibration tin can be loaded into the vehicle reckoner. So bear in listen that there is no going dorsum to an earlier version.

What's the worst instance scenario? If your PCM is frozen or the process is incomplete, you may need to buy a new PCM.

Alternatives to Powertrain Command Module Reflashing

As you tin see, reflashing your PCM isn't a simple process and it volition cost coin to obtain the tools y'all need, often for a 1-time use.
