Vgate Vs450 Update ~upd~

While many diagnostic tools can be updated, the Vgate VS450 is widely regarded as a non-updateable device. Despite having a USB port and an "Update" option in the system menu, there is no official firmware or software provided by the manufacturer to facilitate updates.

VGate VS450 Diagnostic Tool Review

Here is the information regarding updates for the Vgate VS450:

Error 3: Device Bricked (Only flashes red/blue)

• Cause: The update was interrupted.
• Fix: You need to force DFU mode. Disconnect the unit. Hold down the physical button on the side of the vS450 (if your model has one) while plugging it into the OBD2 port. Now run the updater again. This forces a bootloader flash.

Part 2: How to Check Your Current Firmware Version

Before searching for an update, you need to know what version you are running. Here is how to check your Vgate vS450 firmware version: Cause: The update was interrupted

1. Download a BLE Debug App: Install "LightBlue Explorer" (iOS) or "nRF Connect" (Android).
2. Pair the Device: Turn on your car (ignition ON, engine OFF). Plug in the vS450. Pair it via your phone's Bluetooth settings (look for "Vgate vS450").
3. Connect in the App: Open LightBlue Explorer. Connect to the vS450.
4. Locate the Device Information Service: Scroll down to the UUID section. Look for "Firmware Revision String."
   • If you see "v2.3" or lower, you are on legacy firmware (prone to dropouts).
   • If you see "v3.1" or higher, you are on modern firmware.
   • If you see "v4.0" or "Bootloader", you have the latest hardware revision.

Pro Tip: If the device does not show a firmware string and just blinks red/blue rapidly, you are stuck in DFU (Device Firmware Update) mode – you must re-flash the device.

The Core Improvement: Expanding the CAN-Bus Library

The headline feature of the latest update is the massive expansion of the Control Area Network (CAN-Bus) protocol library. Previously, the VS450 excelled with older OBDII protocols but struggled with the high-speed CAN systems found in post-2016 vehicles.

With the new update, the VS450 has successfully integrated newer HS-CAN and MS-CAN protocols. In practical terms, this means the device is no longer limited to reading generic "Check Engine" codes on newer cars. It can now dive deeper into the specific modules of makes like Ford (MS-CAN support for Body Control Modules) and GM, allowing users to access ABS, SRS (airbag), and transmission data on vehicles where third-party tools previously failed.

Specific Manufacturer Fixes

The most telling part of the update log is the list of specific "bug fixes" for manufacturers. It highlights the device's primary strength: bridging the gap for cars that are notoriously difficult to scan.

1. Toyota/Lexus Idle Relearn: The update introduced a functional "Idle Relearn" function for Toyota models. Previously, users had to perform a convoluted manual pedal dance to reset the idle air volume after cleaning a throttle body. The VS450 can now trigger this electronically.
2. VW/Audi Module Addressing: Users reported issues where the scanner would time out when trying to address specific comfort modules in VWs. The firmware update refined the module addressing timing, resolving the "No Response from Module" errors that plagued earlier versions on the Golf and Jetta platforms.
3. Hyundai/Kia Airbag Codes: A persistent issue where generic scanners would read generic airbag codes but fail to clear them on Hyundai models has been addressed. The update includes the specific command sequences required to reset the SRS light on 2015-2019 Hyundai models.

Important Notes

• Don't interrupt power – a failed update can brick the device (rare but possible).
• No PC required – updates are OTA via the app on Android/iOS.
• No firmware ≠ better – Only update if you have a specific problem (e.g., CAN bus errors, missing PIDs, or compatibility with newer iOS/Android).

Step 2: Download the Updater Tool

• For Android: Download "Vgate OBDConfig" from the Google Play Store.
• For iOS: Download "Vgate OBDConfig" from the Apple App Store.
• For Windows: Download the Vgate Update Tool from the official Vgate website (rarely needed unless the OTA fails).

Error 2: "Update Stuck at 15%"

• Cause: Low voltage from the car battery or signal interference.
• Fix: Plug a battery tender (trickle charger) into your car while updating. Turn off all car electronics (radio, lights, AC).
