STR with 1638/1642......Yack!!Yep, I too have fallen into what is sounding like a LARGE BLACK hole known as OBD2 code 1638 & 1642.

From what I've read here I've not seen one definitive identification, diagnosis, or solution to what brings up these two codes. Member NBCat has been a HUGE help to me in the past and via his suggestions on how to 'potentially' diagnose the 'situation' we've narrowed it down to the dash functions are no longer communicating with the CAN. Results? all electrical functions work except power to the starter. Bummer. Ran great on Sunday, didn't drive on Monday....dead on Tuesday a.m. One year old from new battery fully charged (via charger for several hours) as a precaution, head lights on for 2 min. then off....12.65 to 13.4 amps No start. Disconnect +/- poles then put them together for 10 + seconds to reset the computer......no start...same codes.

I've so enjoyed my STR experience for the last 45K miles and 5 years and that being said if these codes end up requiring Sherlock Holmes and Dr. Watson attention accompanied with $1,000.00$ of U.S.D. then, as they said in 'The Sound of Music' ....."Farewell, So Long, Alfeterzen, Good by" Some one can end up with a wonderfully maintained 03 STR with all 100K maintenance including the obscure for a very, very, very fair 'Fire Sale' amount of shekels.

Love to save it....any real life ideas and or cost? Love good news, can deal with bad news, hate 'Bravo Sierra'

Thank you fellow members!

your codes you state are missing a crucial letter .
my instrument cluster has had its CAN mother chip re-soldered twice that i know of in my cars life .
i was told this is a common repair . i wonder if this could be your culprit .
you know you can use the JTIS to pinpoint every can wire and connection your self .
and test each connector with ether at minimum a $10 multi meter for continuity ,or an oscilloscope to watch the pulse widths for correct signals or module failure .
its not too hard and costs only time .

 

If P codes then JTIS does appear quite helpful.

 

Thank you for your insight and suggestions. I'm going follow each 'rabbit hole' and see where it will take me.

Thank you again very much.
