15 Reset Functions of the LAUNCH CRP479

1. Oil Lamp Reset Service
   Allows you to reset the Engine Oil Life system for a new calculation after an oil change.
2. EPB Electronic Park Brake Reset
   Essential for maintaining the safety and efficiency of the electronic braking system.
3. BAT Battery Service
   Enables the scan tool to evaluate battery charge state, monitor close-circuit current, register battery replacement, and activate the vehicle’s rest state.
4. DPF Diesel Particulate Filter Reset
   Supports DPF regeneration, DPF component replacement teach-in, and DPF teach-in after replacing the engine control unit—specifically for Diesel Particulate Filter systems.
5. SAS Steering Angle Sensor Reset
   Clears fault memories in the steering angle sensor and supports calibration.
6. TPMS Tire Pressure Monitoring System Reset
   Displays sensor IDs from the vehicle’s ECU, allows input of replacement TPMS sensor IDs, and enables sensor testing.
   If your new sensor is not original, please contact us.
7. IMMO Key Programming
   Features unique car Key Programming and PIN code reading capabilities, primarily used to disable lost keys and program new replacement key fobs.
8. ABS Bleeding
   Performs ABS brake bleeding to ensure firm brake pads after air has been removed following ABS pump system repairs.
9. Sunroof Reset
   Required when the sunroof control unit experiences communication issues or has been replaced.
10. Suspension Reset
    Resets electronic suspension air ride systems. Ensure all doors are closed, ignition is on (engine off), navigate through the system menu to Suspension Reset, then turn ignition off.
11. Gearbox (Transmission) Reset
    Resets transmission adaptive learning. After performing this procedure, the Engine Control Unit (ECU) and Transmission Control Unit (TCU) will monitor your driving pattern to adapt accordingly. Start the car and drive normally afterward.
12. AFS Headlamp Reset
    “AFS” stands for Adaptive Front-lighting System (used with Bi-Xenon headlights at night). It swivels the headlights during turns; pressing the button locks them straight ahead.
13. Injector Coding
    Helps detect issues such as leaking or dead injectors that may not be apparent even when an injector is disabled. Also aids in identifying problems with ignition or mechanical components that don’t cause RPM loss when an injector is turned off.
14. Throttle Adaptation
    The throttle body controls airflow into the engine via a pivoting butterfly valve. In fuel-injected vehicles, the throttle position and airflow sensors communicate with the computer to adjust fuel delivery. Re-learning the throttle sensor position is required after clearing codes or performing repairs.
15. Gear Learning
    The scan tool monitors specific camshaft position sensor signals to verify conditions are met before proceeding with engine-running procedures.
