EDIAG H581

See the Whole Vehicle First. Diagnose with Confidence

AutoVIN quickly identifies the vehicle with minimal manual input, then EDIAG H581 runs an Auto Scan across 106+ brands—covering Engine, Transmission, ABS, SRS, Body, TPMS, Steering, Suspension, Parking Brake, A/C, Immobilizer, and Gateway modules. Read and clear fault codes, pull ECU information and freeze-frame records, and review live system data to get a complete overview before diving into deeper repairs.

Turn Fault Codes into Clearer Next Steps 

Instead of leaving you with a cryptic code number, H581's built-in OBD fault code library provides clear descriptions and practical repair information for engine-related codes—helping you understand possible causes and plan your next inspection step faster.

4-in-1 Live Data Graphing & Diagnostic Reports 

Monitor real-time sensor streams and merge up to four parameters on a single graph to observe how related readings change together under the same driving or idling conditions. Save complete diagnostic reports to revisit vehicle history, compare before-and-after repair results, and share or print clean documentation for customers and fellow technicians.

Active Bi-Directional Control. Less Guesswork, Faster Fixes

Send commands directly from the H581 tablet to test individual actuators—including fuel injectors, fuel pumps, radiator fans, A/C clutches, power windows, mirrors, door locks, lights, horns, and wipers—and watch how they respond in real time. Comparing the commanded action with the actual component behavior adds concrete evidence to your fault codes and live data, helping you isolate whether the problem lies in the part, wiring, or control module before replacing components.

Go Deeper with Supported ECU Coding 

Use supported ECU coding to handle post-repair module setup and vehicle personalization tasks right in your bay:

• Post-Replacement Configuration Restore: Restore supported configuration settings on compatible vehicles after replacing a control module to complete the electronic setup.
• Vehicle Personalization: Customize supported lighting, door-lock, window, mirror, and warning settings to match vehicle equipment or owner preferences. (Coding availability depends on the vehicle, module, and software. Covers supported configuration changes; does not include ECU programming or firmware flashing.)

35+ Service Functions. More In-House Jobs Covered

Move straight from finding the fault to completing post-repair electronic resets on the same diagnostic tablet. EDIAG H581 covers 35+ commonly used maintenance and adaptation functions—from everyday Oil Reset, EPB Brake Service, BMS Battery Matching, SAS Steering Calibration, and ABS Bleeding to DPF Regeneration, Injector Coding, Throttle Relearn, Gearbox Adaptation, TPMS Reset, Crankshaft Relearn, and more—keeping routine service and part-replacement setups moving smoothly.

Broad 106+ Brand Coverage. Ready for Modern Vehicle Networks

Support for conventional CAN alongside high-speed CAN FD and DoIP protocols allows H581 to communicate across a wider range of modern vehicle electronic architectures without bottlenecks (DoIP diagnostics use the wired connection setup shown in the quick-start guide).

FCA Security Gateway Access via AutoAuth 

Connect to compatible FCA vehicles (Chrysler, Dodge, Jeep, Ram, and Fiat) equipped with a security gateway module. Logging in with your registered FCA AutoAuth account unlocks protected diagnostic operations—including clearing fault codes, running active tests, and performing service resets (requires a separate AutoAuth account and paid third-party subscription, not included with H581).
