This article explains how to resolve the "Your HSM certificate has expired" or "The certificate was not received properly" error message when attempting an ECU Upgrade on Hyundai, Kia, and Genesis smart diagnostic tools, especially after a tablet replacement.

Applicable Products:

  • Hyundai: GDS Smart / GDS Smart RND
  • Kia: KDS 2.0
  • Genesis: GENESIS Smart
  • VCI Devices: VCI II(2), VCI III(3)

Symptoms

After replacing the diagnostic tablet and installing the diagnostic app (GDS Smart, KDS 2.0, or GENESIS Smart), the following warning pop-up appears when attempting to use the ECU Upgrade function:

"Your HSM certificate has expired. Click the Confirm button to try logging in again."

(or)

"The certificate was not received properly. Please log in again."

Smart diagnostic app pop-up: 'Your HSM certificate has expired. Click the Confirm button to try logging in again.'

Example of the certificate error pop-up on the diagnostic app

Cause

This issue occurs because the VCI device (VCI II(2) or VCI III(3)) does not have a valid security certificate. The required certificate must be properly injected from the server to the VCI device during user login.

How to Resolve

Important: The VCI device must NOT be plugged into the vehicle at the start of this procedure.
  1. Log out of the diagnostic app (GDS Smart / KDS 2.0 / GENESIS Smart) and completely terminate the application.
  2. Reboot the tablet PC.
  3. Run the diagnostic app again.
    (Ensure the VCI is NOT plugged into the vehicle at this point.)
  4. Activate Log Collection — just in case this workaround fails.
  5. Log in with your credentials and wait for 2 to 3 minutes for background certification synchronization.
  6. Wire up the tablet PC and the VCI device using the dedicated cable included in the product package.
    See Cable Requirements below.
  7. Then plug the VCI device into the vehicle OBD port.
  8. Wait for 2 to 3 minutes.
  9. Run FCS1 with some ECUs to verify communication.
  10. Try ECU upgrade.
    If it keeps failing with the same error message, please submit the error log.

Cable Requirements

Note: Always use the dedicated VCI II(2) / VCI III(3) cable included in the product package when connecting the tablet PC to the VCI device. Using a third-party or generic USB cable may cause communication errors and prevent the certificate from being properly injected.

If the Issue Persists

If the issue keeps failing with the same error message after following the steps above, please submit the error log to the GIT server.
