Legend
Vehicle is fully onboarded.
Feature is supported via OBD. Requires a connected OBD-II scanner.
Feature is supported via Connected Accounts (Beta).
General support
Sidecar supports the SAEJ1979 OBD-II standard for vehicles produced in the USA since 1996 and vehicles worldwide in the 2000’s. For vehicles that support OBD-II — typically combustion and hybrid vehicles — this enables out-of-the-box support for odometer, speed, fuel tank levels, and 100s of other parameters.
Which OBD scanners work with the Subaru?
Most standard OBD-II scanners are compatible with most vehicles. Sidecar works with a wide range of WiFi and Bluetooth ELM327-based adapters. View list of tested scanners
