Here it is! This is the 1326 page 14.4Mb Diagnostic Manual. This is not the FSM, which is already a sticky, only the DI section of it that's not included in any link and hasn't been available until now. It includes complete, easy to read troubleshooting for all major systems on all years of the IS300. It also contains part numbers(for parts and SST's), the complete wiring schematics and electrical troubleshooting, TSB's, and much more. It also contains all major codes(DTC's), the definition of them, and an easy guide on how to repair the fault(s). It's the same manual Lexus uses and I constantly reference it when helping out on here. Enjoy!

Here's some pin outs for the loose connectors in the ECM box.

No problem. Check the first gen Showroom forum for FSM. I just updated it not too long ago, so there's a link i have added in the OP to a download page.

Jason, do you know if there is a diagnostic manual for the Body? I'm throwing some B-codes, specifically B1421, B1423 and B1411 and I'd like to read up on them.
I believe the diagnostic manual is actually much larger than what is hosted here and may have body codes. I believe there is some in the link here but not many. The FSM covers some of this but not code related. I can tell you...

B1421 is solar sensor malfunction(driver side bubble). FSM shows what the voltage should be and how it fluctuates.

B1423 is open in pressure sensor circuit/abnormal refrigerant pressure. Sensor located in front of radiator/driver side.

B1411 is Room temperature sensor circuit malfunction(located on the driver side and behind panel below steering column.

Now you could use the FSM's specs and see what you have at sensors. Almost sounds like you have some opens. Here's the indexed FSM which you probably have. http://db.tt/xmQ2dI4r

Hey, I know this is an old thread, but any chance someone still has the diagnostics manual they can toss a link up for? The dropbox link in the original post doesn't work anymore. Several things in the FSM reference the DI pages, but it's not available in the other downloads.

Thanks in advance!
