SC300 ECU Main Computer Fried all units affected CHECK YOUR ECU
i say that because as you will see in the pics and the symtoms allot of people are complaining about the same symptoms yet no resolve. here it is.
i actully emailed Lexus Corporate contact i have to get schematic to identify unmarked components.
Hopefully they reply
toyota part number 89661-24301
denso 175000-5270 12v
my nehbor had these complaints.
AC compressor wouldnt turn on.
Rough Idle
Stall (Fuel Shut off)
then it stopped starting and runing (that was the last short to go completely)
and he took it to the dealer they never hooked the car up but told him nothing was wrong (but they never looked any ways)
the Board has open and closed shorts. and its coroded as can be and the 2 brown caps where DEAD. IE i bumped them and they fell off
you can see from the pics there was open and closed shorts and the traces had been dissolved partially to fully by the corrosion.
This thing was such a RPITA to get out of the case. the 150 pin connector needs to be unsoldered and the 5 screws are soldered in to..
heres a link to my picasa with the computer pics.

You can zoom in pretty hard on the album.. (like really zoomed)
here is the list of
part numbers
pins affected by closed or open shorts. (my neibhor crossed some off but those still affected or could have affected)
color code so i know what wires go to what pins when i put back to gether.
