On a lot of newer vehicles, when you replace a module like a body control module or an instrument cluster, you then have to carry out a procedure in order for the vehicle to recognise that the new module has been installed.

It’s something you’ll face with near enough every vehicle manufacturer and it’s an important task that you need to make sure is done correctly.

FIAT, for example, calls this a proxi alignment procedure and it’s a pretty simple sequence of steps for you to follow.

With your scan tool hooked up to the vehicle, go to the Scanner menu then click on Proxi Alignment. Once the tool has identified the vehicle’s ECU you’ll be presented with two options – hit Perform Proxi Alignment Procedure.

Displayed on screen is this message: “This procedure is used to display the proxy configuration status of the entire vehicle and copy the proxy configuration data into any required ECUs. Continue to display the current vehicle status.”

The proxi alignment procedure on FIAT vehicles is an important step for you to complete.

The proxi alignment procedure on FIAT vehicles is an important step for you to complete.

Once you have pressed Continue, you’ll get a list of modules. In this test example on a FIAT 500 we have IPC, Radio, TPM and CTM. 

Because we haven’t replaced anything for the demonstration, each one is marked as Configured. If we had changed anything, that message would change to Not Configured.

Again, press Continue, and at the next stage you will be told that a proxi alignment would need to be carried out if you had replaced any relevant components. You would then be guided through the process.

Once that is complete, at the next screen you will be told that in order to complete the process you need to turn the ignition off and wait for the displayed countdown timer to finish.

When the timer is at an end you will be instructed to turn the ignition back on and hit Continue, which is when you will then be told that the proxi alignment feature is complete. 

So as you can see, it’s a short procedure and a small amount of button presses and you’re ready to set up a new module on the vehicle.
