K+CAN / K+DCAN FTDI USB diagnostic cable is designed for computer diagnostics of BMW vehicles. It provides not only OBD-level data, but also access on the control module (ECU) level, allowing you to perform full diagnostics, tests, service resets and, in some cases, coding (Coding).

✅ 1) Full diagnostics (BMW module / ECU level)

• Read trouble codes (DTC)

• Clear codes and verify repairs

• View fault history / logs (if supported by the software)

• Freeze Frame — parameters recorded at the moment a fault occurred (on some modules)

✅ 2) Live Data — real-time sensor data

• Live parameters: RPM, temperatures, pressures, lambda, MAF/MAP, etc.

• Graphing and data logging / saving (depends on software)

✅ 3) Activation tests (Actuator / Component Tests)

• Cooling fan test

• Fuel pump test

• EGR / throttle / solenoid tests (depending on the model)

• Injector test / balance check (if supported by the software)

• ABS pump / valve tests (if supported by the module and software)

• Switching relays / valves / mechanisms on in test mode

✅ 4) Service functions & resets

• Oil Service Reset

• CBS Reset (Condition Based Service), where supported

• Battery-related service functions (on some models)

✅ 5) ECU / module identification & information

• Module details: part numbers, versions, Coding Index, etc.

• Read VIN and vehicle configuration (depends on software)

✅ 6) Coding — settings configuration/adjustment (often not possible with cheap OBD tools)

• Enable/disable comfort functions (e.g., auto-lock, key-beep, light settings)

• Lighting settings: DRL, Coming/Leaving Home, etc.

• Central locking / door logic customization

• Some warning/chime parameters (in some cases)

• Window/mirror automation behavior (if supported by the module)

• Configuration changes using dedicated software (e.g., NCS Expert)

Note: Coding is not chip tuning — it is changing factory options/functions configuration.

✅ 7) Adaptations / Calibration — where supported

• Throttle adaptation (on some models)

• View or reset transmission adaptations (depending on model)

• Steering Angle Sensor basic calibration (on some vehicles)

• Basic Settings for various sensors (depends on software)

⚠️ 8) Programming / Flashing (Firmware update) — with limitations

• Some modules may be flashed/updated using special software (e.g., WinKFP / ISTA-P)

• Requires stable power supply, correct files and experience

• Not recommended for every generation/module — in some cases ICOM/ENET is better

✅ 9) Multi-module access (much wider than cheap OBD2 dongles)

• Engine control (DME/DDE)

• ABS/DSC

• Airbag (SRS)

• Comfort modules (FRM/GM, etc.)

• Climate, instrument cluster, additional modules — depending on the vehicle
