Step 4: Launch Opcom Run the application as Administrator. Select your language.
Step 5: The Verification Test
Interpreting the result:
Step 6: The Burn Test If your device is verified, immediately go to Test > Test ECM. Run a full system scan. If the scan completes without USB resets, your firmware is stable.
Q: Can I use Opcom 1.67 firmware on a Tech2 device? A: No. Tech2 uses entirely different hardware (PCMCIA/MDI). Opcom is a standalone USB interface.
Q: My device says verified, but it disconnects randomly. Why? A: Verification checks the firmware only, not the USB cable or power supply. Use a high-quality USB 2.0 cable. Do not use USB 3.0 ports or extension hubs. Also, check your vehicle's OBD port voltage (must be stable 12V). opcom 167 firmware verified
Q: Is there a difference between "Opcom 167" and "Opcom 1.67"? A: No. It is shorthand. "Opcom 167" means version 1.67.
Q: Does verified firmware allow me to do immobilizer programming (PIN code read)? A: Yes, verified firmware on v1.67 can read PIN codes via the "Infocolor" or "Security" modules on most Opel models up to 2012. However, newer cars (2015+) require additional security gateway bypass.
Q: Where can I download the verified firmware hex file? A: Distribution of the raw hex file is legally gray. Most GM/Opel forums do not allow direct posting due to copyright (ScanTronic owns the IP). However, communities like MHH Auto have private sections. Your best bet is buying a pre-verified device.
Title: [Confirmed] OPCOM 167 Firmware Verified Step 1: Disable Driver Signature Enforcement (Windows 10/11)
Hi everyone,
Just a quick update to confirm that I have successfully verified the OPCOM 167 firmware.
Test Setup:
The installation went smooth without any errors. The interface is communicating correctly with the ECU, and all diagnostic functions (read faults, live data, actuator tests) are working as expected. No bricked units or communication lag detected. Interpreting the result:
| Symptom | Verification Diagnosis | | :--- | :--- | | "Please update firmware" on every launch | PC software checksum fails; firmware bootloader corrupted. | | Random disconnections during engine scan | Incorrect config bits for oscillator frequency (should be 48MHz for USB). | | CAN modules respond, K-Line does not | Firmware was patched for CAN only; verify hex file contains KWP2000 routines. |
