B1023 integral switch performance

does anyone have flow chart on how to diagnose this code
96-98 GA 3.1L SFI

also what switch are they talking about?

ok this DTC is set by DDM or PDM (drivers door module or passenger door module) so it is inside of the door (maybe door master switch)

I have a list of B,C, and U codes and that ones not listed :screwy:

If it were something like B1017 - Output Driver Module (ODM), that is the drives door module, inside.

Any other codes ??

yes b1021, b1022 and b1023

Never had any problems with SIR system. Is this common problem with GA's.
Air bag light is not lit but I have this codes. I agree I was not able to find b1023 on any of alldata's dtc lists or even on GM SI. But I googled it and now I know that it has to do something with the door module, and it is true my master switch is intermittent (sometimes lets me close the window and sometimes not).
