6. Operating Instructions
6.1. 4-System Diagnostic
This tool allows you to diagnose four core vehicle systems: Engine, Transmission, Anti-lock Braking System (ABS), and Supplemental Restraint System (SRS/Airbag). From the main menu, select 'Diagnose' to begin.
- Engine System Diagnosis: Read and clear Diagnostic Trouble Codes (DTCs), view live data streams to pinpoint engine problems, turn off the Check Engine Light (MIL), and ensure proper engine function.
- ABS System Diagnosis: Access the ABS system to view live data, retrieve fault codes, and troubleshoot issues related to the anti-lock braking system. This helps identify problems with brake components and turn off the ABS warning light.
- SRS System Diagnosis: Detect electronic parameters within the SRS system to check its health status, address potential issues, and turn off the Airbag warning light, ensuring driving safety.
- Transmission System Diagnosis: Check the Transmission system by reading codes and viewing live data to identify problems, clear warning lights, and ensure correct power delivery to the wheels.

6.2. 7 Hot Maintenance Services
The CRP123E/CRP123I V2.0 offers 7 commonly used reset services to assist with vehicle maintenance:
- Oil Lamp Reset: Resets the Oil Life Reminder and switches off the Oil Light after an oil change, ensuring accurate engine oil life calculation.
- EPB Reset (Electronic Parking Brake): Essential when replacing brake pads, wear sensors, or servo motors. Simplifies the braking process.
- Steering Angle Calibration (SAS Reset): Clears fault memories, sets the steering angle to zero, and turns off the steering wheel warning light after replacing the steering angle position sensor.
- Battery Matching (BMS Reset): Performs a resetting operation on the vehicle battery's monitoring unit when the main battery or battery monitoring sensor is replaced, clearing old fault information.
- ABS Bleeding: Facilitates the bleeding process when changing brake fluid, allowing one person to perform the task by activating the brake operation.
- DPF Regeneration (Diesel Particulate Filter): Clears PM (Particulate Matter) from the DPF filter through continuous combustion oxidation, stabilizing the filter.
- Throttle Relearn (Electronic Throttle Adaptation): Makes initial settings to throttle actuators for smooth driving after the throttle body has been replaced or cleaned.
