3. Reprogramming With J2534 Device

To reprogram vehicles using OEM software, you can find a list below of websites that offer subscription software, or visit https://www.acdelcotds.com/ website to find out more about ECU re-flash applications from the OEMs.

Using the additional OEM software, the MaxiFlash Elite can be used as a Pass-Thru diagnostics tool as well, which allows users to read and clear Diagnostic Trouble Codes (DTCs) and data log PIDS, collect sensor data and log generic OBDII data, etc.

Since J2534 allows multiple devices to be connected at once, you must tell the software you want to use the MaxiFlash Elite. Every application will have a different way to select the device, so please consult the software manually.
