Engineered for Professional Workshop Demands
The ELM327 v1.5 Bluetooth PIC18F25K80 (2PCB) is built to deliver speed, accuracy, and stability in busy service bays.
Genuine Microchip PIC18F25K80 & 2PCB Dual-Board Architecture
Cheap v2.1 clones use a single-board COB chip that drops J1850/K-Line protocols and rejects long CAN frames (ATAL). This unit features a genuine 2PCB dual-board layout and PIC18F25K80 processor that executes the full v1.5 AT command set.
Engine Fault Diagnostics & Check Engine (MIL) Reset
Pinpoints why the Check Engine light is illuminated within seconds. Displays stored and pending P, C, B, and U trouble codes with clear descriptions and clears fault memory after repairs.
Real-Time Sensor Gauges, DPF Soot Load & Fuel Trim Analysis
Stream live engine RPM, coolant temperature, turbo boost, O2 sensor voltages, short/long-term fuel trims (STFT/LTFT), battery voltage, and diesel DPF soot load directly on your Android phone or Windows laptop.
Advanced Compatibility with PyRen, DDT4All, AlfaOBD & Car Scanner
Goes beyond basic code reading by supporting Renault/Dacia coding via PyRen (Android) and DDT4All (Windows), FCA diagnostics via AlfaOBD, and comprehensive dashboards via Car Scanner Pro.
LIVE TELEMETRY & PERFORMANCE
Monitor Your Vehicle's Vital Engine & Sensor Parameters in Real Time
Pair the ELM327 v1.5 Bluetooth adapter with Car Scanner ELM OBD2 or Torque Pro on your Android phone or Android head unit to view customizable live gauges:
- Engine & Thermal: Real-time engine RPM, coolant temperature (ideal for cars without a dashboard temperature gauge), intake air temperature (IAT), and calculated engine load
- Fuel & LPG Calibration: Short-Term (STFT) and Long-Term (LTFT) fuel trims, O2 (Lambda) sensor waveforms, and instantaneous/average fuel consumption
- Airflow & Forced Induction: Turbo/manifold absolute pressure (MAP / Boost), mass airflow (MAF) rate, and throttle position percentage (TPS)
- Diesel Emissions & Performance: DPF soot load percentage, EGR status, 0-100 km/h acceleration timer, and braking distance tests
SOFTWARE ECOSYSTEM & CODING
Professional Diagnostic & Coding Apps Powered by Genuine PIC18F25K80
Thanks to its authentic v1.5 command set, this interface communicates reliably with both universal OBD2 dashboards and brand-specific engineering software:

- Ford & Mazda (FORScan Lite / Windows): Detailed fault code reading and live sensor tracking across HS-CAN powertrain and ABS modules
HARDWARE & PLATFORM COMPATIBILITY
Coverage for 2002+ OBD-II Vehicles and Operating Conditions
Built to support all international OBD-II / EOBD communication standards in hardware for broad multi-brand vehicle coverage:
- Supported OBD-II Protocols: SAE J1850 PWM (41.6 kbaud - Ford), SAE J1850 VPW (10.4 kbaud - GM), ISO 9141-2 (5 baud init), ISO 14230-4 KWP2000 (5 baud / fast init), and ISO 15765-4 CAN (11bit/29bit ID, 250/500 kbaud)
- Supported Platforms: Android smartphones, Android tablets, in-dash Android car stereos, and Bluetooth-equipped Windows 7 / 8 / 10 / 11 PCs
- iOS (iPhone / iPad) Limitation: Uses Bluetooth 2.0 (SPP); because Apple iOS restricts Bluetooth 2.0 serial adapters, iPhone users should select a Wi-Fi or Bluetooth 4.0 (BLE) model
- 2018+ SGW Notice: Newer 2018+ Renault and FCA vehicles equipped with a Security Gateway (SGW) module may require an additional SGW Bypass cable for clearing faults or coding

Workshop Application & Operating Guide
Recommended 4-step standard procedure for accurate results.
Plug Into the OBD-II Port
Insert the ELM327 Bluetooth scanner into your vehicle's 16-pin OBD-II diagnostic socket (typically below the steering column) and verify the power LED illuminates.
Turn Ignition On & Pair Bluetooth
Turn the vehicle ignition to ON (or start the engine). Open Bluetooth settings on your Android device or Windows PC, locate 'OBDII', and pair using PIN 1234 (or 0000).
Select Adapter Inside the App
Open your diagnostic app (Car Scanner, Torque Pro, PyRen, or AlfaOBD), go to Settings -> Connection -> Bluetooth, and select 'OBDII'.
Scan Faults & Monitor Live Data
Once the app completes the protocol handshake with the ECU, read/clear fault codes or view real-time sensor gauges.

Frequently Asked Questions
Key technical questions from technicians and workshops about the ELM327 v1.5 Bluetooth PIC18F25K80 (2PCB).
How does this differ from cheap v2.1 ELM327 adapters?
Most low-cost v2.1 adapters use a single-board clone chip that drops J1850 protocols and rejects long CAN frames (ATAL). This unit features a genuine dual-board (2PCB) design with an original Microchip PIC18F25K80 microcontroller and true v1.5 firmware, ensuring compatibility with PyRen, DDT4All, and AlfaOBD.
Does this work with iPhone (iOS)?
No. Apple iOS blocks classic Bluetooth 2.0 SPP OBD2 adapters. This unit works with Android phones, Android tablets, Android car stereos, and Windows PCs.
Can it unlock hidden features on Renault and Dacia with PyRen or DDT4All?
Yes. Thanks to the genuine PIC18F25K80 chip, it communicates reliably with Renault and Dacia CAN-Bus modules via PyRen (Android) or DDT4All (Windows) to enable supported features like gauge sweep, trip computer, cornering fog lights, and seatbelt chime control.
What is the Bluetooth pairing code?
Plug the device into the OBD2 port, turn the ignition on, search for 'OBDII' in your Android or Windows Bluetooth menu, and pair using PIN 1234 (or 0000). Then select 'OBDII' inside your diagnostic app's connection settings.
Which vehicles are compatible?
Compatible with the vast majority of 2002+ OBD-II / EOBD compliant petrol, LPG, and diesel passenger and light commercial vehicles.
Can I leave the adapter plugged into the OBD2 port permanently?
It can stay plugged in for daily driving, but because the OBD2 port supplies constant 12V power even with the ignition off, we recommend unplugging it if the vehicle will sit parked for several days.
