What You Can Diagnose
CarPal SE helps you identify root causes faster by reading fault codes, live sensor values, and module status across the systems it supports:
- Check engine light (MIL) and powertrain fault codes
- Oxygen sensor, fuel trim, and emissions-related DTCs
- Evaporative emissions (EVAP) system faults
- Catalyst efficiency and misfire monitor status
- Freeze frame data captured at the moment of failure
Service & Maintenance Functions
Beyond reading codes, this scanner runs guided service routines that save money on dealer labor. Available functions depend on your vehicle make, model, and year:
- Oil reset
- EPB
- SAS
- TPMS
- Battery registration
How to Use This Tool
Plug the CarPal SE into your vehicle's 16-pin OBD2 port (usually under the dashboard). Turn the ignition to ON — the tool powers from the vehicle and guides you through reading codes in seconds. Use the built-in DTC library to understand each fault, then clear codes after repairs and re-scan to confirm the fix.
Vehicle Compatibility
1996+ OBD2 vehicles with compatible smartphone. AI features require app connectivity.
Always verify that your exact year, make, model, and engine combination is supported before purchase — especially for service resets, bi-directional tests, and brand-specific modules. OBD2 port location is typically under the driver-side dashboard on U.S. vehicles from 1996 onward.
Who Should Buy This
First-time scanner buyers and budget-conscious DIYers who want AI guidance with their codes.
