What Is ANCEL BD200 Bluetooth Code Reader? The BD200 is a professional diagnostic tool designed to read and clear trouble codes and turn off the Check Engine Light (CEL) when an engine fault is detected. It accurately identifies diagnostic trouble codes (DTCs) and potential causes, and supports DTC search, O2 sensor testing, I/M readiness checks, on-board monitor tests, live data streaming, freeze frame data display, EVAP system testing, vehicle information retrieval (VIN), and diagnostic report generation, helping vehicle owners save time and money on maintenance. Why Choose ANCEL BD200 Bluetooth OBD2 Scanner? 1. Dedicated Free App: The ANCEL OBD2 app is developed in-house and provides access to advanced features. It receives annual updates with the latest vehicle data and offers lifetime free usage. 2. Complete OBD2 Functions: The device reads and clears codes, performs DTC searches, O2 sensor tests, I/M readiness checks, on-board monitor tests, live data streaming, freeze frame data display, EVAP system tests, retrieves vehicle information (VIN), and generates diagnostic reports. 3. Additional Features: Includes performance testing for acceleration, braking, and distance, along with PID charting for RPM, VSS, ECT, MAF, and other parameters. Trip analysis records driving conditions such as coolant temperature, speed changes, RPM, and distance. Additional functions include voice alerts for vehicle speed, water temperature, and driving time, as well as battery testing to enhance driving safety. 4. Reliable Bluetooth Connection: Compatible with both Android and iOS devices, the scanner uses Bluetooth 5.0 technology for fast and stable connection to the vehicle’s OBD2 port, enabling quick data access from the ECU and improved user experience. 5. Multi-Language Support: Supports English, German, Spanish, French, Italian, Czech, and Chinese. Compatible with 10 OBDII test modes. (Note: The OBDII system is designed as an emissions program, not a comprehensive diagnostic system.) Common Causes of Check Engine Light Activation: The Check Engine Light may illuminate due to various issues such as oxygen sensor failure, loose or faulty fuel cap, catalytic converter problems, ignition coil malfunctions, worn spark plug wires, vacuum leaks, and other engine-related faults. Key Features: - Read and Clear Codes: Retrieves stored fault codes within seconds and clears pending codes to turn off the Check Engine Light. - EVAP System Test: Performs a leak test on the vehicle’s evaporative emission control system to prevent fuel vapors from escaping into the atmosphere. - Freeze Frame Data: Captures a snapshot of engine parameters at the moment a fault code was recorded. - I/M Readiness Test: Checks the status of emission control system monitors to determine if the vehicle is ready for emissions testing. - On-Board Monitor Test: Allows access to diagnostic monitoring results and enables testing of specific engine components and systems. - O2 Sensor Test: Retrieves and displays the latest O2 sensor monitor test results from the vehicle’s onboard computer. - Vehicle Information: Displays VIN (Vehicle Identification Number), CID (Calibration ID), and CVN (Calibration Verification Number). - Live Data Stream: Provides real-time data on engine parameters including fuel system status, coolant temperature, RPM, and sensor readings. - DTC Lookup: Built-in OBD-II DTC library provides code definitions and possible causes by vehicle make, helping users understand and address issues. Additional Features: - Customizable Dashboard: View real-time data such as RPM, VSS, ECT, MAF, TP, LOAD-PCT, SPARKADV, IAT, VPWR, and other engine parameters. Users can customize the dashboard layout based on preferences. - Performance Testing: Supports acceleration, braking, and sprint tests. Displays test duration, speed, and RPM changes via a PID chart. Automatically generates test reports upon completion.
