Which systems can the C1 scan on my vehicle?

The C1 performs full-system diagnostics across available vehicle modules—not just basic check-engine codes. You can read and clear fault codes and monitor live data streams in real time.

Does the C1 support bidirectional active tests?

Yes. Bidirectional control lets you send commands to vehicle components to verify whether an actuator or circuit is working properly without disassembling parts first. Supported tests depend on the make, model, and year.

How many maintenance reset functions are included with the C1?

The C1 includes 8 commonly used maintenance reset functions for routine service needs. Supported reset functions vary by vehicle.

Does the C1 support key programming?

No. The standard C1 does not include key programming (IMMO). If you need key programming and 15 reset functions, please choose the C1 PRO.

How do software updates work on the C1?

The C1 includes the first year of software updates for free. After the first year, a paid subscription is required if you choose to renew updates, while existing functions in your current version remain usable.

What vehicles and protocols does the C1 support?

It covers 152+ car brands and supports both standard CAN and the CAN-FD protocol used on many newer vehicles.

Can the C1 identify my car automatically and share reports?

Yes. It supports Auto VIN for quick vehicle identification and lets you generate and share diagnostic reports after a scan.

8 Service Functions for Common Maintenance Jobs — Skip Costly Dealership Trips

Why pay the dealership $150+ just to clear a maintenance light? Move seamlessly from diagnosis to post-repair maintenance procedures in the exact same app. EDIAG C1 combines 8 essential service functions for common jobs after maintenance or component replacement right in your own driveway:

  • ABS Bleeding — Cycle the ABS pump to bleed trapped air after brake-system service for a firm, responsive brake pedal.
  • Battery Matching (BMS) — Register a new battery to the ECU after replacement to clear low-voltage faults and extend battery life.
  • Brake Reset (EPB) — Safely retract and reset electronic parking brake calipers after replacing brake pads.
  • DPF Regeneration — Initiate a diesel particulate filter regeneration procedure to clear soot buildup and restore engine power.
  • Throttle Relearn (ETS) — Re-adapt throttle actuator positions after cleaning or relevant maintenance for smooth idling and acceleration.
  • Injector Coding — Write new fuel injector trim codes to the ECU after replacement for optimal fuel delivery and combustion.
  • Oil Maintenance Reset — Reset the oil service reminder light and recalculate maintenance intervals after an oil change.
  • Steering Angle Reset (SAS) — Calibrate the steering angle sensor to keep vehicle stability and traction control accurate.

Bidirectional Active Tests for Targeted Fault Finding

Go beyond passive fault code reading. Send active commands from the EliteDiag app to supported components—such as power windows, exterior lights, mirrors, and door locks—and check their response without blind disassembly:

  • Command Supported Components: Activate supported body components directly from your smartphone and observe their real-time response during diagnosis. Available tests vary by vehicle.
  • Smarter Fault Isolation: Compare the requested action with the actual operation to quickly guide further checks of the component, wiring, or control system.
  • Avoid Unnecessary Part Swaps: Verify exactly what failed before replacing parts—saving hours of guesswork and wasted money.
