Chrysler - J2534 Flash Application __exclusive__
J2534 continues to evolve. SAE J2534 v5.00, the latest iteration of the standard, provides improved functionality that can multiplex communications over several channels, allowing technicians to reprogram vehicles much faster. It also includes VCI device detection and connection management features that enable technicians with wireless connections to multiple vehicles to securely differentiate, isolate, and authenticate each vehicle connection. The new standard is backwards compatible with earlier J2534 API versions and forward-looking enough to accommodate Diagnostic over Internet Protocol (DoIP) communications, enabling wireless, remote "over-the-air" diagnostics and software updates as well as ethernet-based vehicle communications architectures that will appear in vehicles in the coming years.
