KINGBOLEN Ediag ECU Coding Tool

The KINGBOLEN Ediag combines portability, affordability, and professional-grade diagnostics, making it an ideal choice for DIY users, home garages, and small automotive repair shops.

Full-System Diagnostics + AutoVIN + Live Data

The KINGBOLEN Ediag performs full-system diagnostics with AutoVIN technology, automatically identifying your vehicle for faster and more accurate scanning. It provides comprehensive access to major vehicle systems, including the Engine (ECM), Transmission (TCM), ABS, SRS, BCM, TPMS, SAS, BMS, A/C, and more. With real-time Live Data, you can monitor sensor performance, identify abnormal readings, and diagnose vehicle issues with confidence.

15 Reset Functions

Perform routine maintenance with 15 built-in service functions, including Oil Reset, EPB, SAS, TPMS, DPF, Throttle Adaptation, Injector Coding, Battery Registration, ABS Bleeding, IMMO, Transmission Learning, AFS, Suspension, ETS, and Sunroof Initialization.

Service functions vary depending on the vehicle's make, model, year, and system configuration.

Bi-Directional Control + ECU Coding

The KINGBOLEN Ediag supports Bi-Directional Control (Active Tests), allowing you to send commands directly to the vehicle's ECU and operate individual components without using the vehicle's controls. This makes it easier to verify component operation, narrow down faults, and identify the root cause of a problem before replacing parts.

Depending on the vehicle, Active Tests can be performed on components such as power windows, door locks, headlights, mirrors, sunroof, horn, fuel injectors, throttle body, electronic parking brake (EPB), brake vacuum pump, A/C clutch relay, and more—helping you quickly determine whether a component is functioning properly.

The ECU Coding function enables you to code, adapt, or match replacement modules after repairs, ensuring they communicate correctly with the vehicle. On supported models, it also allows you to activate hidden features, personalize vehicle settings, and optimize module performance for brands such as BMW, Mercedes-Benz, GM, and more.

4-in-1 Live Data Stream

Monitor real-time ECU parameters with support for displaying up to four Live Data graphs at the same time. Compare multiple sensor readings side by side using color-coded waveforms to identify irregularities, analyze system performance, and speed up diagnostics.

Broad Vehicle Coverage + Multi-Language Support

Compatible with 115+ vehicle makes, the KINGBOLEN Ediag delivers comprehensive diagnostics for most U.S., Asian, and European vehicles. With support for 12 interface languages, users can easily switch the display language for a more convenient diagnostic experience.
