Chrysler J2534 Application Overview
The Chrysler J2534 System is a combination of the J2534 Application (2010 and newer Model Year Support) and the Chrysler J2534 Flash Application (2009-1996 Model Year Support). J2534 aftermarket users are required and responsible for installing the J2534 device driver provided by the device manufacturer. If you need support installing the device driver software contact the device manufacturer. See the related article “Chrysler J2534 Manual” for additional information. Chrysler J2534 application provides below capabilities:
|The Chrysler J2534 Flash Application:|

Additional Information and Known Issues / Concerns:
If you are reprogramming the 5.9L diesel engine controller on the 1996-2008 Dodge RAM vehicle, it is necessary to also reprogram the VIN after the ECU has been flashed. To write the VIN to the ECU, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.
- 1996-2009 ALL PCMs
If you are REPLACING a PCM or ECM and the vehicle is equipped with a theft deterrent system (Sentry Key), it must be initialized to properly function with the Anti Theft module. You also need to reprogram the VIN when replacing a PCM or ECM. To write the VIN to the ECU and initialize the PCM to work with the theft deterrent system, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.
FCA US LLC Scan Tool Lease Options:
- For 2009 model year vehicles and prior, it may be necessary to use either a DRBIII or a StarSCAN to perform function required after ECU replacement. To lease the DRBIII call 1-586-532-8400 or click here.
- Beginning with 2010 MY, function required to replace an ECU will be supported via the J2534 application.
