ECU update

As required by Regulations R692/2008 and R566/2011, 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.


For reasons related to the electronic architecture of FCA vehicles, a MVCI ISO 22900-2 or (for compatible electronic modules only) a VCI Pass-Thru SAE J2534 is needed for these activities. The device may be connected to a generic PC which supports Java Web Start 32 bit via a LAN, W-LAN, Bluetooth® or USB port.


Reprogramming and configurations may be carried out by purchasing "Single Transaction ECU Packages". "Time-Limited ECU Packages", lasting for the time shown below, can be purchased for initialisations:

  • 1 hour
  • 1 day
  • 1 month
  • 1 year

Click on "Your Subscriptions" on the red side bar on the top right to access your single packages or subscriptions.
