Does someone have list of IPC codes and testing procedures for each?
The above mentioned codes have nothing to do with the open loop for air bag system. It has to do with loss of serial data for PCM, EBCM and SIR.
Yes this sometimes can be confusing, so two weeks ago I even asked "how can I diagnose B1023?" which I thought was about some kind of integral switch. GM sometimes uses shared codes depending on which module was tested for DTC's. In my case I tested IPC codes, and this is what I got: B1021, B1022 and B1023 anyone had similar problem?

As far as I know these arent shared...
DTC B1021 Driver Deployment Loop Resistance High
DTC B1022 Driver Deployment Loop Resistance Low
If the last dtc was B1024 Driver Deployment Loop Short to Ground, it would make it easier.
Is your ABS module wet or have corrosion on its terminals ?
Why were you looking for IPC codes, yours fauling out ??
Only two codes I know of for hte IPC is ;
B1438 IPC High Voltage Output Overcurrent to IPM
B1556 IPC EEPROM Odo/Configuration Error
DTC B1021 Driver Deployment Loop Resistance High
DTC B1022 Driver Deployment Loop Resistance Low

Yes XI I did not know also. But there are shared codes. I will try to find a short paragraph about this from alldata. What are you using Alldata or Mitchell's on demand?

At work I use Mitchell, for about 20 years now.
