Obdpeak K2 Firmware Update |top|

OBDPEAK K2 (and its 11.3-inch K2 Pro variant) can be updated to improve performance, fix software bugs, and optimize features like Wireless CarPlay and Android Auto.

Step 3: Load the Updater Tool

  • Select the correct COM port (check Device Manager under “Ports” – look for Silicon Labs CP210x or CH340).
  • Click “Load Firmware” and select the provided .bin or .hex file.
  • Crucially: Compare the version number. If the new file is v2.3.0 and yours is v2.1.4, proceed. If versions are identical, skip.

What If There Is No Update Available?

A common frustration with the Obdpeak K2 is that sometimes the app shows "No Updates Available," yet the scanner still malfunctions (e.g., it won't read ABS codes on a Ford or refuses to connect to a Toyota).

In this scenario, the issue might not be firmware, but app compatibility. OBDPEAK K2 (and its 11

  • Check the Manual: Ensure the specific function you are trying to use is supported by the K2 hardware. Some cheaper K2 units are "OBD2 only" (engine codes) and do not support ABS/SRS despite the app implying they might.
  • Contact Support: Obdpeak support is generally responsive. If you suspect a bug that an update hasn't fixed, email their support team with your Device Version Number (found in the app settings) and your car's make/model/year.

Step-by-step firmware update workflow (practical)

  1. Park safely and switch the vehicle to accessory/on so the ECU stays awake (follow device/app guidance).
  2. Open the official OBDPEAK app (or updater tool).
  3. Connect the K2 via Bluetooth (or USB if supported).
  4. Check for updates in the app’s device settings or firmware section.
  5. Review release notes and ensure prerequisites (e.g., minimum app version).
  6. Begin update and do not disconnect power or Bluetooth until it finishes.
  7. Wait for reboot: The device may restart; allow the app to re-pair automatically.
  8. Verify functionality: Run basic scans, read live data, and check trouble-code read/clear operations.
  9. Restore custom settings if needed.

Method B: Over-The-Air (App) Update – (If supported)

Note: As of late 2024, the OBDPeak K2 does not support full OTA firmware updates via the mobile app for the base OS. However, the companion app updates DTC databases. Do not confuse "DTC database updates" with "Firmware updates."

To update the DTC library only:

  1. Open the OBDPeak app on your phone.
  2. Connect to the K2 via WiFi.
  3. Go to Settings > Update > Check for Database Updates.
  4. Download and install. This does not touch the core firmware.

Prerequisites: What You’ll Need

Before starting, gather these:

  • OBDPeak K2 dongle.
  • Windows PC (Windows 10/11 preferred). Mac/Linux users will need a VM or Boot Camp—there’s no native support.
  • Micro USB cable that supports data transfer. Most phone charging cables won’t work (they lack the data lines). Test with a known good external hard drive cable.
  • The official firmware updater tool – This is the tricky part. OBDPeak does not publicly host firmware files. You must:
    • Contact OBDPeak support directly (support@obdpeak.com) with your order ID.
    • Or download from a reputable seller’s resource page (e.g., BAFX, Veepeak’s legacy downloads—they often cross-brand).
  • Driver pack: CH340 or CP210x USB-to-serial drivers (depending on your K2 revision). Check your device’s PCB near the USB port.

Troubleshooting Common Update Issues

Because budget OBD2 scanners rely on wireless updates, things can sometimes go wrong. Here are the three most common problems and how to fix them.
