Navigating Access Challenges with Yanmar YDS

⚠️ Unable to log in to your Yanmar YDS account.

Cause: Incorrect User ID or Password, browser issues (cookies/JavaScript disabled), or a required password change.

Solution: First, carefully re-enter your User ID and Password, checking for typos and ensuring Caps Lock is off. If the issue persists, click on the Forgot your password? link on the login page to initiate a password reset process. We understand being locked out can be frustrating, so try the password reset first. Also, verify that your browser has cookies and JavaScript enabled, as these are essential for the portal's functionality. For YDS 2.0 users, ensure you are using your YDS 2.0 specific password. If you still face difficulties, consult your business unit representative or sales agent for assistance with user ID and password reassignment.

⚠️ The YDS portal displays a 'System Upgrade Underway' message or requires re-login after an update.

Cause: The system is undergoing or has just completed an automatic update.

Solution: This is a normal operational procedure, not a malfunction. Allow the update process screen to complete. Once the login screen reappears, simply re-enter your User ID and Password to regain access to your dashboard.
