Trying to help someone out who has a MY98 Forester with an OBD-II connector BUT it is not OBD-II compliant. It is only SSM and appears to be wired with pins 12 & 13 as determined as Subaru specific for these years....

Now, there are a lot of tech diagrams saying how to make a cable up, but can you buy one of these cables off the shelf.

Obviously the Elmscan is only OBD-II and the Tactrix is OBD-II/SSM, but the latter the SSM pins are not 12 & 13, so for his year a specific cable is needed...

If anyone thinks you can change pin outs to get it to work on an Elmscan, it would be most interesting, but I do not believe this will work.

Any ideas?

The MY98 ecu is not OBD compliant so you can't scan it using OBD tools.

There is some info on the subject here: Subaru ECU Monitor

Hi Andrew,

Thanks for that....I did find this yesterday after a bit of a search on here. There are a few SSM tools out there, JDash, VWRX SSM and others....

He just needs a cable.

Hi

I am looking for someone near me (preferably) with a Tactrix cable (or similar) and a Subaru!

I have written some firmware to access the SSM protocol from the OBDKey device which I have developed. I have tested the SSM protocol back to back with another emulated controller and this works, but I haven't tested on a Subaru yet. I have the interface electronics (K and L line / ISO 9141 and KWP2000) tested so there is no risk to the owner of interface electronics damage (I'll underwrite any testing anyway).

Is there anyone near me (north London/ Herts/Beds/Bucks) who would be happy to help?

I'll reward them with an OBDKey unit which supports all OBD-II protocols PLUS SSM once it's fully tested and working on a Subaru.

It would be important that you have a Tactrix cable (or similar) in case we need to compare operations.

Thanks
