SAE J2534

For access to SAE J2534 information go to the service information website,

SAE J2534 pass-thru tools and software calibrations are found in the Related Documents link at the bottom of the homepage. For complete information covering FCA's J2534 product, refer to the J2534 Manual 3.3.

The J2534 flash application can be downloaded from TechAuthority. Note that it includes a separate application for 2009 and prior model years (for emission modules only) and a newer application (wiTECH Diagnostic System) supporting 2010 and newer model years.

The wiTECH 2.0 application is a cloud-based diagnostic system with enhanced security and requires an additional subscription to TechAuthority resources. Note that FCA's own MicroPod II is a SAE J2534-compliant device but compatibility with the new security features of wiTECH 2.0 requires an upgraded MicroPod II with a serial number of WSP-31560 or higher. .

Note: Older MicroPod II units (before serial number WSP-31560) will not communicate with the wiTECH 2.0 programming application but will communicate with wiTECH 1.0. However, wiTECH 1.0 will be discontinued in late 2017 and not supported.

FCA recommends the newer MicroPod II as the vehicle communications interface but aftermarket device manufacturers are known to be developing wiTECH 2.0-compatible J2534 devices. Techs are warned to confirm that compatibility with their device manufacturer prior to use.

The TechAuthority website provides access to TechAuthority Online with a purchased subscription. The subscription allows access to the SAE J2534 Application, SAE J2534 applicable ECU flash files, Technical Service Bulletins (TSBs), service diagnostic procedures, and Chrysler wiring diagrams.

Which models and model years of vehicles can be reprogrammed?

The wiTECH 2.0 (SAE J2534) application will do both emission and non-emission diagnostics and programming for all 2018 and newer models with limited coverage on earlier models. For a list of models and model years programmable using wiTECH 2.0, view the reference chart under "RELATED DOCUMENTS." Navigate to the DCCTools Knowledgebase and find the "Supported Vehicles" (pdf) document clicking through the left-side menu into the "Chrysler J2534 Application" folder. Also:
  • Some 1995 and newer OBDII vehicles can use the J2534 flash application for emission-related modules only.
  • Emission related functions for engine and transmission control modules can also be reprogrammed with Chrysler's diagnostic scan tools.
  • Powertrain Control Module Initialization requires the use of Chrysler's diagnostic scan tools.
  • Specific body control modules can be reprogrammed with Chrysler's diagnostic scan tools.

How does a technician determine whether a reprogramming event is needed for a particular vehicle?

  1. Launch
  2. On bottom of home page, click on “Related Documents and Links” and a new page will load.
  3. Inside the “Related Documents” section of the page, click on “Flash Availability - J2534/Pass Thru Device” to view the PDF document that contains a list of supported calibration files.  The PDF contains the old and new calibration part numbers, along with the corresponding TSBs that can either be opened from the server, or saved to the user’s hard-disk drive, then opened.  This requires a PDF viewer to view Chrysler’s file.

What OEM equipment is available to reprogram vehicles?
