B1023 integral switch performance

[3100]

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

also what switch are they talking about?

[3100]

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

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

Any other codes ??

[3100]

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).
