Non-alarming Fiat

Owners of a 2012 Fiat 500 and its model variants may experience an inoperative vehicle theft alarm (VTA). Enabling the VTA in the body control module (BCM) will correct the condition.

Using a scan tool with the appropriate diagnostic procedures available in TechCONNECT, verify that all systems are functioning as designed. If DTCs are present, record them on the repair order and repair as necessary before proceeding.

If a customer’s VIN is listed in VIP or your RRT VIN list, perform the repair.

NOTE: The wiTECH Diagnostic Application will not display a flash update ICON (lightning bolt) for this update. This function is to enable VTA only, and will not update the ECU part number. Proceed  with the following flash procedures to enable the VTA.

  1. Install a battery charger to ensure that battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process.
  2. Using the wiTECH diagnostic application for flashing a BCM is made available through the wiTECH diagnostic application. For instructions, select the “HELP” tab on the upper portion of the wiTECH window, the “HELP CONTENTS.” This will open the Welcome to wiTECH Help screen, where help topics can then be selected.
  3. Clear any DTCs that may have been set in other modules due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow the tech to clear them.
