Overview of the XTOOL D9 MAX

The XTOOL D9 MAX combines a rugged Android 10 platform with professional-grade hardware, delivering rapid diagnostics and module programming for Chrysler-family vehicles and beyond. With full system auto VIN scan and OE-level fault code retrieval, it covers all onboard ECUs—including engine, transmission, ABS, SRS, BCM, and more—for more than 10,000 vehicle models worldwide. Its integrated 9.7-inch high-resolution touchscreen and quad-core 1.5 GHz processor ensure fluid operation and clear data visualization, even in bright shop environments.

Advanced ECU Reprogramming Capabilities

J2534 Pass-Through Programming

The D9 MAX supports J2534 pass-through programming, enabling seamless integration with OEM factory software for Chrysler, Dodge, and Jeep vehicle platforms. Technicians can perform genuine FCA-level ECU replacements, firmware updates, and security PIN resets without needing the expensive dealer-only tools. Acting as a compliant pass-through interface, allows users to leverage subscription-based OEM suites while benefiting from XTOOL’s user-friendly hardware.

Offline ECU Programming & ECU Coding

In addition to online programming, the D9 MAX offers offline ECU reflashing capabilities that eliminate the need for an active internet connection during module updates, saving both data usage and shop time. Its ECU coding feature allows technicians to customize and match new or replacement modules, activate hidden factory options (such as comfort lighting or towing assistance), and disable nuisance reminders (like seatbelt chimes).

Comprehensive Diagnostic and Maintenance Functions

Intelligent Topology Mapping

Leveraging an intelligent topology map, the D9 MAX visually displays the vehicle’s network architecture, highlighting each ECU’s location, status, and interconnections. This graphical interface drastically reduces diagnosis time by pinpointing fault origins and illustrating live data pathways in real time.

Pre/Post Scan and Diagnostic Reporting

The enhanced Pre/Post Scan feature captures baseline data before repairs and validates results after service completion, ensuring transparency and accuracy in maintenance workflows. Diagnostic Report V2.0 offers customizable shop-branded reports, complete with freeze-frame images, parameter graphs, and technician notes—ideal for customer presentations and record keeping.

42+ Specialized Maintenance Services

Beyond basic code reading, the D9 MAX provides over 42 one-touch service functions, including oil reset, EPB, SAS, DPF regeneration, throttle adaptation, BMS reset, ABS bleeding, injector coding, fuel trim reset, cylinder power balance, crankshaft sensor relearn, stop/start reset, and A/F ratio calibration. These utilities streamline routine maintenance and complex calibrations, making the tool indispensable for Chrysler service bays.

Bi-Directional Control and Key Programming

Bi-directional (active) tests enable verification of component functionality by commanding actuators, such as radiator fans, fuel pumps, window motors, and lighting systems, directly from the scanner interface. Additionally, the integrated key programming module supports Chrysler immobilizer procedures, allowing PIN retrieval, key fob addition, and complete key replacement for lost or extra remote shells (verify vehicle compatibility before use).

Exclusive Support for Chrysler via FCA AutoAuth

Recognizing the secure boot-and-login requirements of modern FCA vehicles, the D9 MAX includes FCA AutoAuth functionality, ensuring compliant access to Chrysler, Dodge, and Jeep ECUs without dealer-level logins. This feature preserves factory security protocols while reducing the hassle of external authentications and token purchases.

Cutting-Edge Communication Protocols (DoIP & CAN FD)

To accommodate next-generation vehicle networks, the D9 MAX supports DoIP (Diagnostics over IP) for rapid diagnostics on platforms like modern Land Rover, Jaguar, and late-model BMW chassis. It also implements CAN FD (Flexible Data-Rate) for high-speed data transfer on GM MY2020+ vehicles, ensuring compatibility with the latest automobile communication standards.

Robust Hardware Specifications

Equipped with a durable Android 10 operating system, the D9 MAX features a 9.7-inch capacitive touchscreen (1024×768 resolution), quad-core 1.8 GHz CPU, 4 GB RAM, and 128 GB internal storage for rapid app launches and large data logs. Its 6400 mAh (7.4 V) high-capacity battery provides extended runtime—equivalent to 12,800 mAh at 3.7 V—while dual-band Wi-Fi ensures stable, high-speed connectivity during online operations. A built-in 8 MP rear camera further assists in capturing vehicle condition images for detailed reports.

Benefits and Value Proposition

Investing in the XTOOL D9 MAX grants professional technicians three years of free software updates, ensuring ongoing support for newly released vehicles and features. A two-year warranty and 24/7 customer support provide added peace of mind, while its competitive price point—currently $2,099, down from $2,699—delivers exceptional ROI for high-volume shops.
