11 Chrysler J2534 Flash Application
• Provides support for all 1996 – 2009 vehicles.
• Supports ECU reprogramming for emission control modules only (ECM, PCM, TCM, and CVT).
• The user is responsible for downloading the correct ECU reprogramming/flash files from TechAuthority’s website. Click here to download ECU reprogramming/file files.
• FCA US LLC recommends the CTC J2534 Vehicle Box Device for SCI ECU reprogramming. SCI reprogramming is used on most PCMs and TCMs prior to the introduction of CAN bus vehicles which began in 2004 HB (Durango).
• Requires TechAuthority subscription.
11.1 Flash Availability Document
The J2534 Flash Availability document is intended to provide Aftermarket users with the correct ECU Flash reprogramming part number and designated supercedence list without having to purchase a TechAuthority Online subscription.
Supercedence is the list of supported software part numbers that a specific ECU flash will update. If the current software part number is not listed the flash will not update the controller and is not applicable to that particular YME (Year, Model, Engine) and part.
Click here to view the J2534 Flash Availability Document. The user can also navigate to the knowledge base website to view this document:
https://kb.fcawitech.com > “wiTECH 2.0 Public Articles – Aftermarket” > J2534 > J2534 Flash Availability Document.
11.2 Information and Known Issues / Concerns:
• 1996 – 2008 5.9L ECM (Cummins): 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:
o Aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII).
o wiTECH 2.0 J2534 application if the vehicle is supported. Refer to the vehicle reference chart in section 4 or click here to check if the wiTECH 2.0 J2534 application supports your vehicle.
• 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:
o Aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII).
o wiTECH 2.0 J2534 application if the vehicle is supported. Refer to the vehicle reference chart in section 4 or click here to check if the wiTECH 2.0 J2534 application supports your vehicle.

Note: Problems can occur when an ECU module is replaced with the wrong ECU module. Selecting the wrong calibration file can lead to poor vehicle performance, engine damage or a vehicle that will not start. Obtaining the original ECU part number and following supercedence rules is extremely important when replacing an ECU. Once an ECU has been reprogrammed, the new calibration cannot be removed. Previously used ECU modules are not supported and cannot be reprogrammed to a different calibration.

** To perform diagnostics, data read, routines, and system tests on an applicable vehicle, an OEM FCA US LLC scan tool (DRBIII or StarSCAN) is required if the vehicle is not supported by wiTECH 2.0 J2534 application. To lease the DRBIII, call 1-586-532-8494 or Click here. ** Click here to view how to launch the Chrysler J2534 Flash Application.
** 1996 – 2008 5.9L ECM (Cummins): 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). To lease the DRBIII, call 1-586-532-8494 or Click here.
** 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). To lease the DRBIII, call 1-586-532-8494 or Click here.
