Diagnosing Subaru Problems

Through the years a lot has changed about diagnostic procedures and more importantly the tools in which are used to help a Technician reach the right conclusions. Pictured below are the three different Subaru Select monitors that have been in use. The current version is part scan tool and part pc based platform that also gives us the ability to re-flash a Subaru vehicles ECM (Engine Control Module). This is an important distinction between us and some of the other shops around, we believe in staying current with the diagnostic tools and procedures to keep you Subaru running its best.

Some Subaru problems pertaining to performance and check engine lights have been addressed with a logic update much in the same way a bug in a pc is resolved with a software update. This is true of some of the other systems in the car as well. We believe this is a very important service to offer our customers and a great way to truly fix problems other shops may not be able to take care of.

The Subaru Select Monitor “the original” was capable of reading codes, and one line of data could be read at a time as well as a series of lights to indicate function of various components.

The Subaru Select Monitor II came out in time for OBD II (On Board Diagnostics two) and is a big step up from the Select monitor, being able to read multiple lines of data, tap into other systems the ability to graph sensor readings and it has a built in volt ohm meter with digital oscilloscope. The Subaru select monitor II has the ability to re-flash the ECM as well with the proper flash cartridge.

The Subaru Select Monitor III is part Pc and part scan tool or pass through device. The Scan tool has a built in flash memory card and can be used as a “flight recorder” meaning sensor readings can be recorded over the course of a test drive and later uploaded to the PC where the data can be looked at by the diagnosing technician. The new version of the Select Monitor also allows the technician to graph sensor data, look at multiple lines of data (more than ever before) Reflash the Vehicle’s Computer, program remotes and is a great needed tool to diagnose modern Subaru problems.
