That makes three ECU's I've replaced caps on without bungling the job(I guess my US Navy training didn't go for naught). Thanks for the heads up on JDM and Celsior, looks like it works on USA models too.

So the USDM LS400s are the same.
There is one more item I 'd better inform you which is the case of the circuit opening relay. See my post below.

I guess it's time for me to get a cheap oscilloscope. I've been putting that off and it makes troubleshooting very hard without one. My grandsons car is still running great, since the original fix(?). Does give me another direction to go if it happens again. Thanks, Yamae. But I think I am out of the role of working on cars for a while. Fell off a chair yesterday and they just put a pin on my left femur. Perhaps 6 weeks before I'm much use again.

So I pulled me ecu today and not quite sure I see anything visually. Can someone be my second set of eyes? Unfortunately no one I know would even begin to identify anything out of the norm.
