The Launch CRP909 is the newest evolutionary Android-based smart diagnostic solution designed for 12V passenger cars, SUVs, light-duty trucks, and pickup trucks. As a full-system scanner, it can diagnose all electronic systems in your vehicle. What sets it apart is its inclusion of 15 specialized reset and maintenance functions—covering frequently used services such as Oil Reset, Electronic Parking Brake (EPB) Reset, Steering Angle Calibration, ABS Bleeding, TPMS Reset, Gear Learning, IMMO Service, Injector Coding, Battery Maintenance, DPF Regeneration, Throttle Position Reset, Gearbox Matching, AFS Reset, Sunroof Initialization, and Suspension Calibration. This makes it an ideal tool for professional repair garages, car beauty service centers, auto mechanics, and DIY car owners.

The CRP909 supports complete diagnostics for the following vehicle systems:

The CRP909 enables completion of commonly required maintenance and reset procedures, including:

Resets the Engine Oil Life system for accurate monitoring after an oil change.
Enables safe and effective maintenance of the electronic braking system—deactivating/activating brake control, managing brake fluid, opening/closing brake pads, and resetting brakes after disc or pad replacement.
Evaluates battery charge state, monitors closed-circuit current, registers battery replacement, and activates the vehicle’s rest state.
Supports DPF regeneration, component replacement teach-in, and reinitialization after ECU replacement.
Clears fault memories and performs calibration of the steering angle sensor.
Displays sensor IDs from the vehicle’s ECU, allows input of new TPMS sensor IDs after replacement, and supports sensor testing.
Programs new replacement key fobs and disables lost keys using unique pin code reading and Key Programming capabilities.
Performs ABS brake bleeding to ensure firm brake pedal feel after air has been removed post-repair of the ABS pump system.
Reinitializes sunroof memory—typically required after battery replacement or when the vehicle loses power.
Resets electronic air suspension systems; requires all doors closed, ignition on (KOEO), and navigation through the vehicle’s message system to access suspension reset options.
Resets transmission adaptive learning. After initiating the procedure, the ECU and TCU collaborate to learn driving patterns during normal operation.
Resets Bi-Xenon headlights that swivel with steering input; this function locks them to point straight ahead when activated.
Facilitates coding of fuel injectors. Note: Leaking or failed injectors may not always be detected during disable tests, and related ignition or mechanical issues might not cause noticeable RPM drops.
Re-learns throttle body position after cleaning, repair, or ECU reset. The throttle body regulates airflow via a butterfly valve, with position communicated to the ECU via sensors to adjust fuel delivery accordingly.
Monitors camshaft position sensor signals to verify conditions are met before proceeding with engine-running adaptation procedures.
Compatible with OBD-II and EOBD protocols, supporting a wide range of brands including:
Note: Not all special functions are available for every vehicle model. If unsure, please provide your car’s brand, model, and year—or verify compatibility at the official support page: http://qcar.x431.com/newqcar/
