This connection is open under the driver side dash. The car is a '00 Outback sedan. Does anyone here recognize the connection and what it goes to?

 

#1 rule of subarus - NEVER connect the green connectors. They are not for our use, they are for the dealership to use for diagnostics and flashing the ECU.

 

Just leave them be.

I'm going to expand on what Sir Nipper stated...hopefully live to tell about it.

 

The green connectors are used for 'active' reading of CEL codes. On the Legacy from '90-94 (and maybe your '00) there's also a set of black connectors used for 'stored' codes. Both sets may or may not be next to each other, but usually on Legacys are under the driver's side of the dash, as in your pic.

 

Here's a LINK about using them on older Subies, but I DO NOT Guarantee the results are the same on your '00.

 

There is a recent post on this site about doing this on the OBD2 cars, and it includes the code #s and descriptions...but can't find it right now.

 

However, my DISCLAIMER is that if/when you do have a CEL, take it to a place w/an OBD2 scanner to get it checked.

 

Good luck,

TD

It works best with a subaru select scanner. They dont work with the generic code readers.

 

Sir?

Thanks.

 

I have scanning software I use for the Suby codes I was just curious about the connection.

THAT green connector is not for "our" use as Nipper described. There are green connectors elsewhere on your car that are not for diagnostics. Each model is slightly different so it's not fair to say ALL green connectors are for diagnostics. Case and point would be 93-?? Imprezas have a green connector like that under the driver's side dash for diagnostics, but under the dash on the passangers side is an identical connector that goes up to the dome light.
