Question about 2003 Toyota 4Runner
The problem is not 100% solved. I have figured out that the problem is in the ground circut for the "Body ECU" system. The only circut effectfed is the door, ignition switch ilumination. If a ground is forced to the circut it works oK.
What I need is a diagram of the internal workings of the "body ECU". I have not yet removed it but it can be much more than a bunch of relays. By the way tell the guy with SD22 Nissan to search SD22. The sole distributor for that product is located in SanFran.
