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 when triggered. It accurately identifies diagnostic trouble codes (DTCs) and potential causes, performs DTC search, O2 sensor test, I/M readiness check, on-board monitor test, reads live data stream, displays freeze frame data, conducts EVAP system tests, retrieves vehicle information such as VIN, and generates comprehensive diagnostic reports, helping vehicle owners save time and money on maintenance. Why Choose ANCEL BD200 Bluetooth OBD2 Scanner? 1. Exclusive Free APP: The ANCEL OBD2 app is developed in-house and unlocks all advanced features. It receives annual updates with the latest vehicle data and offers lifetime free usage. 2. Full OBD2 Functions: Capable of reading and clearing codes, performing DTC search, O2 sensor test, I/M readiness, on-board monitor test, reading data stream, displaying freeze frame data, EVAP system test, retrieving vehicle information (VIN), and generating diagnostic reports. 3. Additional Functions: Includes performance testing for vehicle acceleration, braking, and distance, along with PID charting for RPM, VSS, ECT, MAF, and other parameters. Trip analysis records trip status including coolant temperature, speed changes, RPM, and distance. Features include voice alerts for vehicle speed, water temperature, and driving time, as well as battery testing to enhance driving safety. 4. Stable Connection: Compatible with both Android and iOS devices, utilizing Bluetooth 5.0 technology for fast and stable connection to the vehicle's OBD2 port. Enables quick data retrieval from the ECU and enhances overall user experience. 5. Supported Languages: English, German, Spanish, French, Italian, Czech, Chinese. Supports 10 OBDII Test Modes (Note: The OBDII system is primarily designed for emissions monitoring, not full diagnostic analysis.) What Could Cause the Check Engine Light to Turn On? The check engine light may illuminate due to various issues such as oxygen sensor failure, loose fuel cap, catalytic converter problems, ignition coil faults, worn spark plug wires, or vacuum leaks. Read and Clear Codes: Retrieves fault codes within seconds and clears pending codes, turning 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: Captures a snapshot of engine parameters at the moment a fault code was recorded. I/M Readiness Test: Checks the status of emission 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 components and systems related to emissions. O2 Sensor Test: Retrieves and displays the latest O2 sensor monitor test results from the vehicles onboard computer. Vehicle Information: Displays VIN (Vehicle Identification Number), CID (Calibration ID), and CVN (Calibration Verification Number). Live Data Stream: Reads real-time data including fuel system status, engine coolant temperature, RPM, and various sensor readings to monitor vehicle performance. DTC Lookup: Built-in updated OBD-II DTC library. After entering a fault code and selecting the vehicle make, the tool displays the code definition and possible causes to assist in troubleshooting. Special Features: Customized Dashboard: View real-time data such as RPM, VSS, ECT, MAF, TP, LOAD-PCT, SPARKADV, IAT, VPWR, and engine-related data streams. Users can customize the dashboard layout based on personal preferences. Performance Test: Supports acceleration, braking, and sprint testing. Displays test duration, speed, and RPM changes via the dashboard. Includes a PID chart showing RPM, VSS, ECT, MAF, and other values. Automatically generates a test report upon completion.
