Honda SIS (Service Information System) is accessible only to authorized Honda dealers and service partners with active accounts and the proper training. Consumers cannot access the system directly.
What Honda SIS is and who can use it
Honda SIS is a secure, centralized repository of official service data, including repair procedures, wiring diagrams, technical service bulletins, and parts information. Access is normally restricted to employees of Honda-authorized dealerships, service centers, and select business partners who have completed the required training and security agreements. If you are not a member of an authorized network, you will not be able to log in or retrieve service data from SIS.
Getting access: Step-by-step
To begin using Honda SIS, follow the standard process used by your dealership or authorized partner. The steps outlined below reflect the typical workflow used across regions, though exact details may vary by country.
- Confirm your eligibility with your dealership’s SIS administrator or regional Honda service network administrator.
- Submit the required registration paperwork and sign any applicable confidentiality agreements or user policies.
- Complete any mandated training covering data security, proper use of service information, and warranty guidelines.
- Prepare your secure access setup (for example, compliant devices and any network security requirements such as VPN or 2‑factor authentication).
- Receive your login credentials and access the Honda SIS portal through the approved entry point.
- Navigate to the service information you need—procedures, diagrams, and data relevant to the current vehicle you are servicing.
Once these steps are completed, your access will be activated according to your role and region. If you change employers or departments, your SIS entitlement typically must be reassessed and reissued by the new administrator.
Registration and training specifics
Registration often requires verification of dealership affiliation, role within the service organization, and compliance with data-handling policies. Training typically covers how to search for information, how to interpret diagrams and procedures, and how to handle sensitive data in accordance with Honda’s security standards.
What you can access in SIS
The Service Information System provides authoritative, model-specific data that technicians rely on to perform repairs accurately and efficiently. The following items are commonly available through SIS, depending on region and user permissions.

Access to this content helps ensure repairs align with Honda engineering standards and warranty requirements while supporting efficient workflow within authorized service networks.
Troubleshooting access issues
Login and access problems can stem from eligibility, credential issues, or regional restrictions. Here are common scenarios and how to address them.
- Login failure or locked account: verify your username, ensure the account is active, and follow the password reset or unlock process provided by your administrator.
- Revoked or suspended access: contact your SIS administrator to review entitlement and compliance with security policies.
- Regional or dealership restrictions: confirm that your facility is authorized for the correct region and that your role has the appropriate permissions.
- Device or browser compatibility: use the officially supported browser and device configuration as specified by Honda.
- 2FA or security prompts: complete any required two-factor authentication setup and keep backup codes secure.
If issues persist, escalate to your dealership’s SIS administrator or Honda technical support and reference any ticket numbers for follow-up.
Alternatives for customers and non-affiliates
Owners and non-affiliates generally cannot access Honda SIS. For owners, Honda provides other resources such as the Honda Owner Portal or My Honda+ for service history, recalls, maintenance schedules, and manuals. Independent repair shops seeking official guidance should consult their regional Honda partner networks or authorized calibration and training programs offered through the dealer network.
Summary
Access to Honda SIS is designed for authorized dealers and service partners with active accounts and completed training. The system delivers authoritative service data, including repair procedures, wiring diagrams, and parts information, to support proper vehicle service. Consumers do not have SIS access, and owners should use official owner resources for information. Always follow your administrator’s guidelines and security policies to maintain access and protect sensitive data.
