ECU update

As required by Regulation R858/2018, FCA is offering functions to allow independent repairers to reprogram, configure and initialise ECUs and electronic components without needing to purchase the official diagnostic tool of the FCA service network.


To register your VCI SAE J2534, click the adjacent image, which will take you to a common portal for the FIAT, LANCIA, ALFA ROMEO, FIAT PROFESSIONAL, ABARTH, CHRYSLER, JEEP and DODGE brands.

After logging in, you first need to register at least one VCI.
To get the Serial Number, you have to download the Customer, run it with the VCI J2534 connected to the PC and go to the About page, as shown in the comment.

Here is a list of VCIs that FCA has already tested and validated:

Brand Product
Bosch MTS 6531
Bright Star Engineering J2534 (BSJ/BSJR)
Controller Technologies Corporation Pulsar
Dearborn Group, Inc. d-briDGe PRO
Drew Technologies, Inc. CARDAQ-Plus3

Once the data are entered, request approval.

After the correct verifications, the user gets an email with confirmation that the registration took place.

The registration is automatically valid for vehicles of all brands.

After registering the MicroPOD, you will be asked to download the OKTA (One Key Time Access) or Google Authenticator mobile APP, which will require a separate registration.
These applications are essential because they allow two-factor authentication in accordance with cyber security regulations.


After the VCI registration, you can acquire a subscription to the diagnostic which can last:

  • 3 days (considered the average time frame for the operation on the vehicle and related activities; less time makes no sense)
  • 1 month
  • 1 year

In order to use the subscription, you need to launch the customer who is installed on your PC. You will be asked to log in with your OKTA or Google Authenticator credentials.

As regards using more advanced functions (access to connected vehicles, reprogramming and bidirectional diagnostics) you need to activate the additional subscriptions to the technical documentation, inasmuch as these functions presuppose access to Technical Bulletins (for reprogramming), to troubleshooting procedures (for bidirectional programming in the case of DTC with documentary support) or tracking a user and vehicle (for activities on connected vehicles).

These subscriptions can be purchased on specific portals for the brand concerned, and are associated with the user rather than the device:

  • FLAPH: a subscription to the Online Technical Documentation containing at least the brand concerned, including the manuals, can be purchased for at least 1 hour on this portal.
  • CJD: a subscription on www.techauthority.com can be purchased for at least 1 hour.

You cannot run reprogramming of control modules that might be linked to official FCA Recall Campaigns. Because these activities are the manufacturer's responsibility and tied to tracking their completion, they are entrusted exclusively to the official FCA network.
