Engine/Transmission (1998.5 - 2002) What is p1693 and what does PDONE mean?

[LRueter]

2000 just quit on me. Driving down the road and no hesitation or anything just quit running. Turns over but does not start. Have fuel at the filter and fuel comming out of injector pump.

Hey LRueter!

Do any other code's show up? I believe the 1693 is a companion code that show's up when somethig is wrong! The PDone just mean's the scan check for codes is "Done"! Good luck! Check for other code's!

The P1693 code is a companion code..... This means there is a code stored in one of the companion computers. You will need a code scanner to read the stored code. PDone means just what it says..... it is the end of test sequence message.

1693 is a companion code. Did you let it run the diags all the way through? It should read 2 sets of codes and tell you pdone twice.

If it only finds codes in the PCM but not the ECM (or the reverse), it only displays P done once.



From what I've seen, if it finds codes in both computers, then the code list starts with P ECU, then codes, then P done, then P PCU, then codes, then P done again. But if you only have them in one computer, then it just does the codes and P done.

Mine does the P PCU - P done and then P ECU - P done. If there are no codes present, then nothing shows up between the P xCU and P done.



It has been reported that some ECU codes aren't pulled unless you look at them with a scanner. Check at Autozone - they'll pull them for free.
