leagend BA570 is a comprehensive diagnostic tool for vehicles. It reads and clears engine trouble codes, supports dynamic data flow with 249 ECU operating parameters, provides freeze-frame data and I/M status, checks and resets the engine indicator and read vehicle information (VIN, IDs, CVNs).
leagend BA570 offers dual system detection for the engine and transmission systems and tests 12V/6V lead-acid batteries, including CCA, internal resistance, voltage, state of charge (SoC), state of health (SoH). It features built-in LED lights, real-time voltage curve displays, and stores up to 1750 test records for efficient analysis and diagnostics.
