🔍 Professional Diagnostic Coverage
The CRP129X performs full-system diagnostics across all critical control units of the vehicle:
| System | Description |
|---|---|
| Engine (ECU) | Reads and clears fault codes, shows live parameters (RPM, fuel pressure, O₂, coolant temp), and supports injector corrections. |
| Transmission | Accesses automatic gearbox control data, adapts new components, and performs clutch-learning after replacement. |
| ABS (Anti-lock Braking System) | Reads sensor faults, performs ABS bleeding, and tests system pressure or valve operation. |
| SRS (Airbag System) | Identifies crash data, resets warning lights, and analyses safety restraint malfunctions. |
| EPB (Electronic Parking Brake) | Releases the brake actuator to replace pads, then re-initialises the system. |
| TPMS (Tyre Pressure Monitoring) | Registers or resets sensor IDs after tyre change or wheel rotation. |
| DPF (Diesel Particulate Filter) | Performs regeneration, monitors soot load, and resets learned values. |
| BMS (Battery Management System) | Registers new batteries and calibrates state-of-charge readings. |
| AFS (Adaptive Front-Lighting System) | Resets headlight alignment following replacement or suspension work. |
| AdBlue (SCR System) | Calibrates and resets urea injection system for diesel exhaust after-treatment. |
These modules can be read individually or scanned automatically through Auto Scan, giving technicians a complete overview of the vehicle’s health in minutes.
🔄 12 Essential Service & Reset Functions
| Function | Description |
|---|---|
| Oil Reset | Clears oil-change reminder and resets service intervals after maintenance. |
| EPB Reset | Opens and closes electronic parking-brake actuators for brake-pad replacement. |
| DPF Regeneration | Initiates manual regeneration of the diesel particulate filter to restore performance. |
