About DENSO DST-i

The DST-i is a DENSO-built SAE J2534 vehicle interface used by several Japanese manufacturers. Subaru specifies it for its SSM software, and the newer DST-010 continues the line.

What it does

  • Required by Subaru for SSM4 on 2016 and newer vehicles, and used with SSM5 for reprogramming.
  • Offered as a supported interface for Honda and Acura diagnostics through Honda's tool programme.

Good to know

  • Subaru does not approve aftermarket USB cables for SSM4.
  • Owners sometimes use generic J2534 devices with SSM software through unofficial driver workarounds; Subaru does not support this.
