The US EPA regulation mandates that automotive OEMs must comply with SAE J2534 pass-through reprogramming from model year 2004 and forward for their Powertrain ECU’s. If an OEM cannot comply with J2534 by model year 2004, they may request one year additional extension to become J2534 compliant. Additionally, the specification includes a provision that allows OEMs to use the J2534 reprogramming method on 1996 through 2003 model year vehicles as long as OEMs make all necessary additional hardware (i.e. Vehicle connection cables for use with device and/or it’s auxiliary pin) available to the aftermarket. If an OEM cannot retroactively implement the J2534 pass-through reprogramming solution with or without special cables, they must make available to equipment and tool companies any information needed to develop aftermarket equivalents of their OEM-specific reprogramming hardware and software.
J2534 Pass Through is professional. Original MaxiFlash Pro Reprogramming Tool offers the most. Using the OEM software, this premier tool is capable of providing.
High-speed Internet connection is highly recommended. You will be required to download the calibration files directly from the OEM websites, so shorter downloads equate to quicker reprogram times.
Prevalent with European car makes, in some cases the OEM will require a direct connection between the vehicle, the in-shop PC (running the reprogramming application software) and the OEM server. It’s this latter condition that requires the speedy high-speed connection. Consult OEM website guidance for minimum Internet connection specification requirements. There a 3 key points that need to be followed for successful reprogramming. • The vehicle’s system voltage must remain constant (specified by OE) during the reprogramming.
• The vehicle’s electrical system needs to be functioning properly (e. Program At90s2313 With Arduino Due more. g. Battery state of charge and state of health, cable connections and alternator charge performance). Note: Battery Testers can be a key addition to ensure these systems are up to the task of reprogramming. • Follow the manufacturer’s reprogramming instructions in a step-by-step manner! What tools does Bosch Diagnostic offer to fill my J2534 reprogramming needs? Mastertech VCI, Flasher Pro, and Flasher LT support aftermarket reprogramming functions offered by OEM reprogramming application software. The General Motors MDI can also be used in the aftermarket although its intended use is with GM TIS.
Which vehicles can be reprogrammed using Bosch J2534 tools? Vehicles with ECUs that can be reprogrammed are defined by the automotive OEM. Consult the OEM application guide for vehicles and ECUs that can be reprogrammed using the J2534 function. A check of the OEM service information website is often a good place to start. In addition, www.nastf.org may also contain helpful application information.
