1. Within one hour of your successful 12-month subscription purchase, you will receive an email that will contain a hyperlink, user ID and password. If you don’t receive this email, check your spam folder. If you are still unable to find it, contact PDI at (248) 896-6150 or [email protected].
2. Please make sure you are using the laptop that will be associated with and used exclusively for Subaru.
3. Click on the link in the email and you will be directed to the SSM4 download center, where you will enter your credentials that were provided to you in the email.
4. Within the 12-month subscription period, every time Subaru has a new release, you will receive another email with a new hyperlink, user ID and password to download the new software. Once entered, the download begins.
5. Again, make sure you are downloading the SSM4 software files to the laptop to be used with the DENSO.
6. Once the file download is complete, the software will present you with four install options.
7. Install all four options and then exit the install dialogue screen once this has been completed.

1. After the SSM4 software installation is complete, connect the DENSO box to the laptop using the USB cable provided.
2. At this point, a unique product ID number will appear in a dialogue window. Please record the product ID number somewhere safe.
3. You will then be prompted to enter a product password. Please note that the “SKIP” button is no longer active, and the software will not be usable until the password is entered.
4. Email the unique product ID and software version number that you recorded to: [email protected] for processing. After we receive your email, the product password will subsequently be provided back to you via email within 3 business days (excluding U.S. and Japanese holidays).
5. After receipt of the product password (copy/paste this from the email you will receive), enter it upon next use of the SSM4 software. This step will complete registration of the DENSO device, SSM4 software and laptop.
