Thanks for doing that. Subaru dealers over here are only interesting in selling Imprezas. Their attitude is "buy an impreza or go away". I'd be surprised if they even have the SVX select monitor cartridge.

I assume the select monitor is a TTL device like the ECU, so no TTL to RS232 conversion is being done. This, coupled with the revelation that the Select Monitor gets good data seems to indicate that the problem is in the adapter box.

Strange how it works for the TCU though, and how the problem is intermittant, and only affects some SVXes.
