Product Functions:
EV Diagnose
By comparing the differences between new energy vehicles and traditional vehicles, the diagnostic software logic has been optimized in terms of overall vehicle diagnostics, improving diagnostic speed while ensuring accuracy and enhancing the diagnostic experience. Currently, diagnostic software has been developed for multiple vehicle models, including BYD, Xpeng Motors, Leapmotor, Neta, Roewe, GAC, BAIC New Energy, Zeekr, etc., with a model coverage rate of over 95%. More models are continuously being updated…



System and Function:
OEM-level diagnostic functions, graphical display of the entire vehicle system structure for a comprehensive view; rapid scanning to quickly locate faults; test plans guide repairs step by step.



Through battery pack data streams, the cause of faults can be precisely located, improving diagnostic and repair efficiency.



Can Bus Pin Detection
Used to detect the voltage of the pins on the vehicle's OBD-II diagnostic socket and the supported protocol types, helping technicians determine whether the OBD-II diagnostic interface has a fault.



EV Battery Pack Diagnostics
Multiple Battery Pack Diagnostic Methods
Dedicated Harness Diagnosis: Diagnosis using dedicated battery pack connectors, simple and safe, plug-and-play.
Jumper Diagnosis: When no standard battery pack interface is available, connect to the battery pack interface according to the diagnostic software instructions.
OBD Diagnosis: Battery pack diagnosis via the vehicle's OBD-16 interface.



The battery pack is a key component of EVs. Testing the battery pack is one of the important steps in EV inspection. Using the battery pack diagnostic software, you can quickly read battery pack information, including but not limited to the number of battery pack modules, SOC, SOH, current temperature, etc. Additionally, it can deeply read the voltage and temperature values of individual cells within each module, helping technicians quickly understand the battery pack status and providing guidance for subsequent repairs.



Supports generating diagnostic reports, as well as report sharing and printing.



Special Functions
Supports matching, coding, and common special functions for programmable modules on most vehicle models,

Such as for EV: EV air conditioning compressor testing, coolant replacement, high voltage poweroff(HVPO), onboard charger offline testing(OBC Test), DCDC converter offline testing(DCDC Test), 48V mild hybrid component testing(48V MHEV Test), chip data repair,

For Automotive: maintenance light reset, throttle matching, steering angle reset, brake pad reset, tire pressure reset, immobilizer matching, ABS bleeding, battery matching, gear learning, injector coding, sunroof initialization, headlight matching, suspension matching, transmission matching, exhaust gas recirculation, window calibration, seat calibration, tire modification, language setting, A/F adjustment, electronic water pump activation, transport mode deactivation, startstop setting, automatic air conditioning initialization, engine power balance, highvoltage battery health detection, intelligent cruise control system calibration, motor angular position sensor calibration, and other special functions.
