I'm having this same issue in my 2006 subaru outback 2.5i. ACC and ERR light on my info panel and draining my battery.
I found the post saying to cut the green/yellow wire under the driver's seat that goes to the tire pressure monitor control system that this model does not have.
Is there a way to do this without removing the driver's seat?
Where is this connector located under the seat?
Help
Thanks,
Chris
