How to choose a Best Subaru OBD Diagnostic Scanner?

If you’re looking for the best obd2 diagnostic scanners that will allow Subaru owners to perform in-depth troubleshooting themselves, look no further.


Let’s get to it.

The OBD2 scanners listed here are able to scan the following systems:

  • ABS – Anti-lock brake system.
  • SRS – Airbag system.
  • ECU – Engine Control System.
  • TCU – Automatic Transmission Control Unit.

If you are looking for an OBD2 that will allow you to read engine codes and erase the Check Engine Light you don’t need to spend hundreds of dollars on a diagnostic scanner. Any generic OBD2 scanner will get the job done.

Let’s start taking a look at the scanner that is used at Subaru dealerships. Next we will look at some alternatives and affordable diagnostic scanners for Subaru owners.

Subaru dealerships use the Select Monitor III scanner. The scanner will allow you to access all systems on Subaru vehicles.  The Monitor III is without a doubt the best OBD2 scanner for Subaru cars.
