Does the C1 PRO diagnose all vehicle systems or only the engine?

The C1 PRO runs full-system diagnostics across the vehicle, giving you access to fault codes and real-time live data across factory modules beyond the engine.

Can I test components directly with the C1 PRO?

Yes. With bidirectional control (active tests), you can command components directly from the tool to pinpoint faults faster. Available active tests vary by vehicle make, model, and year.

Which 15 reset services are included on the C1 PRO?

The C1 PRO includes 15 maintenance and reset functions: Oil Maintenance Reset, Brake Reset, Battery Matching, ABS Bleeding, Electric Throttle Relearn, Steering Angle Reset, DPF Regen, Injector Coding, TPMS Reset, Adaptive Front Lighting, Gearbox Relearn, EGR Adaptation, Sunroof Reset, Air Level Calibration, and IMMO Program. Available services depend on the vehicle.

Does the C1 PRO support key programming (IMMO)?

Yes. IMMO Program / Key Programming is built into the C1 PRO. Because anti-theft coverage varies by manufacturer and model year, please check compatibility with your vehicle before buying.

Are there any subscription fees for updates on the C1 PRO?

No. The C1 PRO comes with lifetime free software updates, so you get ongoing vehicle coverage and software updates with no annual renewal fee.

How many car brands does the C1 PRO cover, and does it support CAN-FD?

It works on 113 car brands and supports both CAN and CAN-FD protocols, allowing you to diagnose newer CAN-FD-equipped vehicles.

Does the C1 PRO include Auto VIN and shareable health reports?

Yes. Auto VIN automatically reads your vehicle identification number at startup, and you can save and share diagnostic reports once your scan is complete.

Full-System Diagnostics Across 76+ Vehicle Brands & 1-Tap Smog Pre-Check 

Unlike basic OBD2 code readers that only check powertrain codes, the EDIAG C1 PRO gives you real-time access to all system data across 76+ vehicle brands—including Engine, Transmission, ABS, SRS/Airbag, and A/C systems—with zero hidden blind spots:

  • Multi-Module Fault Scanning: Read and clear diagnostic trouble codes (DTCs) and review live data across all available control units when a warning light or symptom involves more than just the engine.
  • Pre-Inspection I/M Readiness Check: Review emissions-monitor status in seconds before your annual state smog check to confirm whether the vehicle has completed its required monitor tests.
  • Complete Vehicle Overview: See a clear, comprehensive picture of your vehicle's true condition and re-scan after repairs to verify every fix.

AI-Assisted Fault-Code Analysis — Diagnose Smarter & Faster 

Reading a trouble code is only half the battle—knowing what to investigate next saves you time and money! EliteDiag's built-in AI assistant helps interpret complex fault codes and makes scan results effortless to understand:

  • Intelligent Code Interpretation: Translates cryptic DTCs into clear, plain-English context so both DIYers and technicians can quickly grasp what triggered the fault.
  • Guided Troubleshooting Context: Adds actionable diagnostic guidance when you are deciding which component, sensor, or circuit to check next.
  • Data-Driven Repair Decisions: Review AI-assisted guidance alongside live sensor data and active component-test results to pinpoint the root problem without guesswork.

4-in-1 Live Data Graphs & Shareable Diagnostic Reports 

Turn raw sensor numbers into clear visual insights! Track real-time readings during diagnosis and document every scan with professional reports:

  • 4-in-1 Merged Live Graphing: Compare up to 4 live data parameters in a single graph to see how related readings change together and spot abnormal trends or inconsistent responses fast.
  • Before-and-After Repair Records: Save and compare full diagnostic reports to keep a permanent record of findings and review improvements after completing a repair.
  • 1-Tap Mechanic Sharing: Easily export and share diagnostic reports from your phone to discuss scan results clearly with a technician or customer.

15 Service Functions for Maintenance & Relearns — Skip Costly Dealership Trips 

Why pay the dealership $150+ just to clear a service light or adapt a new component? Handle essential maintenance procedures and post-repair electronic setup in the exact same app you use for diagnosis. EDIAG C1 PRO includes 15 high-demand reset, matching, and learning functions:

  • Oil Maintenance Reset — Reset the oil service reminder light and maintenance intervals after an oil change.
  • EPB / Brake Reset — Safely retract and reset electronic parking brake calipers during brake pad service.
  • ABS Bleeding — Run an automated ABS bleeding routine during brake service for a firm, responsive pedal.
  • Battery Matching (BMS) — Register and match a replacement battery to the ECU to clear low-voltage faults and extend battery life.
  • DPF Regeneration — Initiate diesel particulate filter regeneration to clear soot buildup and restore engine power.
  • Injector Coding — Enter new fuel injector trim codes after replacement for optimal fuel delivery.
  • Throttle Relearn (ETS) — Relearn electronic throttle body settings after cleaning or maintenance for smooth idling.
  • Transmission Relearn — Perform gearbox adaptation and relearn procedures for smooth, accurate shifting.
  • Steering Angle Reset (SAS) — Carry out steering-angle sensor calibration to keep vehicle stability control accurate.
  • TPMS Reset — Perform tire pressure monitoring system resets after tire rotation or sensor replacement.
  • EGR Adaptation — Perform Exhaust Gas Recirculation (EGR) adaptation after cleaning or valve replacement.
  • Key Matching (IMMO) — Carry out immobilizer key-matching procedures on compatible vehicles.
  • Headlight Reset (AFS) — Initialize and reset adaptive front-lighting systems.
  • Sunroof Reset — Run sunroof initialization and pinch-protection reset procedures.
  • Suspension Level Calibration — Perform electronic or air suspension ride-height calibration.

Bidirectional Control for Active Component Tests — Pinpoint Faults Without Disassembly 

Go far beyond passive fault code reading! Send active commands straight from the EliteDiag app to test exterior lights, door locks, power windows, the A/C clutch, fuel pump, cooling fan, and other onboard actuators directly from your phone—without blind disassembly:

  • Direct Command & Response: Activate components on demand from your smartphone and observe their real-time response right at the vehicle.
  • Targeted Fault Isolation: Command-and-response checks give you far more information than a fault code alone—helping you narrow down which component, wiring circuit, or control signal needs further inspection.
  • Avoid Unnecessary Part Swaps: Verify exactly what failed before buying and replacing parts—saving hours of labor and wasted money.
