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 power‑off(HVPO), on‑board charger offline testing(OBC Test), DC‑DC 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, start‑stop setting, automatic air conditioning initialization, engine power balance, high‑voltage battery health detection, intelligent cruise control system calibration, motor angular position sensor calibration, and other special functions.
