The drain pump shorted out, a common problem on this model. Replaced that.
The short blew the ACST (a kind of a switch) on the main board, a common problem on this model. Replaced that.
The damage was more extensive on main board than I’d hoped, an additional relay is probably bad and an unknown number of other components. Replaced that.
The new main board fails to communicate with the inverter board, a common problem on this model.
I’m going to borrow a DMM to troubleshoot, but at this point I’m stuck between dumping more money into it, or returning both the new main board and the drain pump which have not seen action yet, and just buying a new washer.
Ah yeah, same here. I guess everywhere? There’s mechanics here for carbureted classics and moderns of course. Nobody wanted to work on a stop-gap TBI system and nobody kept the old OBD1 scanners that was a reasonable distance from home anyways, certainly nobody local.
I bought a hacky OBD1 to USB cable from eBay during this ordeal but I was done before it arrived. Did test it out for future use and it works since it came bundled with a CD full of GM scanner profiles. ProTuner software is pretty complicated so there’s a learning curve just navigating it. Maybe people make them for Toyota too?
I am seriously considering engine-swapping it from a 3VZE to a 5VZE. Not just because of ODBII, but also because the 3VZE is apparently just about the only not-reliable engine Toyota ever made.
