4.2 4-System Diagnostics
The CRP123I V3 allows you to diagnose four critical vehicle systems:
- Engine System: Read and clear Diagnostic Trouble Codes (DTCs), view live data streams to pinpoint engine problems, and turn off the Check Engine Light.
- ABS (Anti-lock Braking System): Access ABS system data, retrieve fault codes, and visually inspect brake components to troubleshoot issues and turn off the ABS warning light.
- SRS (Supplemental Restraint System - Airbag): Detect electronic parameters within the SRS system to check its health status, address potential issues, and turn off the Airbag warning light.
- Transmission System: Check the transmission system by reading codes or viewing live data to ensure proper power delivery to the wheels and turn off the transmission warning light.
4.3 7 Reset Services
The CRP123I V3 provides 7 commonly used maintenance reset services:
- Oil Lamp Reset: Resets the Oil Life Reminder and switches off the Oil Light after an oil change.
- EPB (Electronic Parking Brake) Reset: Essential for brake pad replacement, sensor issues, or servo motor replacement. Simplifies the braking system maintenance.
- SAS (Steering Angle Sensor) Calibration: Clears fault memories, sets the steering angle to zero, and turns off the steering wheel warning light after replacing the steering angle position sensor.
- BMS (Battery Management System) Reset: Performs a resetting operation on the vehicle battery's monitoring unit after battery replacement, clearing old fault information.
- ABS Bleeding: Facilitates the process of changing brake fluid by allowing one person to perform the brake operation, preventing air from entering the brake fluid pipeline.
- DPF (Diesel Particulate Filter) Regeneration: Clears particulate matter from the DPF filter through continuous combustion oxidation mode to stabilize the filter.
- Throttle Relearn: Makes initial settings to throttle actuators for smooth driving after the throttle body has been replaced or cleaned.
4.4 Full 10 OBD2 Functions
The scanner supports all 10 test modes for OBD-II compliant vehicles (1996 and newer):
- Reading Codes: Displays detailed descriptions of Diagnostic Trouble Codes (DTCs).
- Erasing Codes & Reset: Turns off the Check Engine Light (MIL), clears DTCs, and resets monitors.
- Data Stream: Reads and displays live ECU/PCM data stream, with graphical plotting and freeze frame data storage.
- I/M Readiness Status: Checks if emission-related systems are operating correctly and ready for inspection.
- Read Live Data Stream: Shows continuous data stream information from the vehicle in a live graphic (waveform) display.
- View Freeze Frame Data: Records vehicle conditions at the time an emission-related fault occurs.
- O2 Sensor Test: Retrieves and displays O2 sensor monitor test results.
