The legacy process requires manual file selection. After launching the Chrysler J2534 Flash Application and minimizing it, you must download the applicable calibration files from the TechAuthority website before proceeding. The J2534 Flash Availability document provides the correct ECU flash reprogramming part numbers and designated supercedence lists. Review the document for the specific vehicle YME (Year, Model, Engine) and ECU, then check the list for updated ECU part numbers and supercedence. If the current software part number is not listed in the supercedence list, the flash will not update the controller and is not applicable to that particular vehicle configuration.
Some newer Chrysler vehicles require specialized hardware beyond standard J2534 interfaces. For example, 2015–2018 Jeep Renegade, Fiat 500X, Fiat Spider, the all-new Jeep Compass, and Alfa Romeo Giulia vehicles require DrewTech's CarDAQ "Mega-CAN Add-on Module" to support the specific CAN bus implementations used on these platforms.

Subscription/Token Use: You select the update and "pay" using your pre-purchased TechAuthority credits.
The Flash: The software erases the old memory and writes the new data. This usually takes between 5 and 20 minutes depending on the module size.
A high-quality USB cable is non-negotiable. If the connection drops during a flash, you risk "bricking" the vehicle’s computer.
