Key Features Advanced Active Test / Bidirectional Control ABS System Diagnostics SRS Airbag System Diagnostics Full OBD2 Functions Oil Reset Service SAS (Steering Angle Sensor) Reset BMS (Battery Management System) Reset Live Data Stream with Graphic Display DTC Lookup Function PC Printing Support Lifetime Free Online Updates Multi-Language Support Wide Vehicle Coverage User-Friendly Interface 3 Hot Keys for Quick Access Active Tests / Bidirectional Control One of the biggest advantages of the LAUNCH CR629 is its Active Test capability, also known as bidirectional control. Unlike ordinary OBD2 scanners that only read information from the vehicle, the CR629 can send commands directly to vehicle systems and components to perform functional tests. This allows users to actively test vehicle components and verify whether specific systems are operating properly. What Active Tests Can Do The scanner can command certain vehicle components such as: Fuel pump activation Electronic brake control ABS component testing SRS system testing Module communication tests Actuator operations This helps technicians quickly identify hidden issues in ABS and SRS systems when warning lights appear on the dashboard. The active test feature significantly reduces diagnostic time and improves troubleshooting accuracy. Note: Active Test functionality currently supports approximately 20 vehicle brands. Compatibility may vary depending on vehicle make, model, and year. Supported Languages CR629 supports English, French, German, Spanish, Portuguese, Russian, Japanese, and Italian. ABS System Diagnostics The LAUNCH CR629 provides complete ABS system diagnostics to help monitor braking system performance and safety. ABS Functions Include Read Version Information Identify detailed information about the ABS control module including: Unit type Version numbers System specifications Read Diagnostic Trouble Codes (DTCs) Retrieve ABS-related fault codes to determine the exact cause of warning lights and braking system issues. Clear ABS Fault Codes After repairs are completed, users can erase ABS fault codes and turn off ABS warning lights. Read ABS Live Data View real-time ABS data such as: Wheel speed sensor information Vehicle speed Brake system parameters Sensor performance Active Tests for ABS Perform bidirectional testing of ABS components to verify proper operation and locate hidden problems. SRS Airbag System Diagnostics The CR629 also supports advanced diagnostics for the Supplemental Restraint System (SRS), commonly known as the airbag system. SRS Diagnostic Functions Read SRS Fault Codes Identify airbag system problems and determine the cause of SRS warning lights. Clear SRS Codes Erase stored airbag system codes after repairs and reset warning indicators. Read Live SRS Data Monitor real-time data from airbag sensors and related safety components. Active Tests for SRS Perform active testing of airbag-related components and modules to ensure proper system functionality. This feature helps maintain vehicle safety and ensures the SRS system operates correctly during emergencies. 3 Special Reset Services The LAUNCH CR629 includes three important maintenance reset functions that help maintain proper vehicle operation after repairs or maintenance. 1. Oil Reset Service The Oil Reset function allows users to reset the oil maintenance reminder after changing the engine oil and oil filter. Benefits of Oil Reset Resets oil life monitoring system Clears oil service reminder lights Helps maintain accurate service intervals Ensures proper maintenance tracking Regular oil changes are critical for engine performance, lubrication, and long-term durability. 2. SAS Reset (Steering Angle Sensor Reset) The SAS Reset function recalibrates the steering angle sensor after: Wheel alignment Steering repairs Suspension repairs Steering component replacement Proper SAS calibration helps maintain accurate communication between the steering wheel and ESC (Electronic Stability Control) system. SAS Reset Helps: Restore steering accuracy Maintain vehicle stability Ensure proper ESC functionality Improve driving safety 3. BMS Reset (Battery Management System Reset) The BMS Reset function is used after battery replacement. It helps: Clear old battery information from ECU memory Register the new battery Reset battery monitoring system Improve charging system performance This ensures the ECU correctly recognizes the newly installed battery and monitors it accurately. Full OBD2 Functions The LAUNCH CR629 supports all major OBD2 diagnostic modes for most post-1996 OBD2 and CAN vehicles. Full OBD2 Functions Include Read Diagnostic Trouble Codes Erase Diagnostic Trouble Codes Turn Off Check Engine Light (MIL) Live Data Stream Freeze Frame Data I/M Readiness Status O2 Sensor Test EVAP System Test On-Board Monitor Test Component Test Vehicle Information Retrieval Benefits of Full OBD2 Diagnostics Turn Off Check Engine Light After repairing the issue and clearing the trouble codes, the scanner can automatically turn off the check engine light. Pass Emissions and Smog Tests The I/M Readiness function helps users check whether the vehicle is ready for emissions inspection before taking the test. This improves the chances of passing smog inspections successfully. Locate Emission Problems Quickly The scanner helps identify the exact cause of emission-related problems through accurate fault code reading and real-time data analysis. Live Data Stream and Graphic Display The LAUNCH CR629 supports real-time live data monitoring. Users can monitor parameters including: Engine RPM Coolant temperature MAP values TPS values Vehicle speed Air flow readings Ambient temperature O2 sensor data The scanner can display data in both: Numerical format Graphic waveform format Graphic display makes data easier to understand and helps identify abnormal sensor behavior more quickly. DTC Lookup Function The built-in DTC Lookup Library allows users to instantly search and understand diagnostic trouble codes directly on the scanner without needing internet searches or repair manuals. This feature saves time and improves troubleshooting efficiency. PC Printing Function Users can connect the CR629 to a computer and print diagnostic reports for: Customer records Repair documentation Technical analysis Workshop reports This feature is useful for professional repair shops and technicians. User-Friendly Design The LAUNCH CR629 is designed with simplicity and ease of use in mind.
