0033-00, 0032-00, 0039-00, 004A-00, 0034-00.

 My car  : chevy 2011 HHr 2.2LT  automatic.

Hi, im getting what i described as sub fault codes : 0033-00, 0032-00, 0039-00, 004A-00, 0034-00. These are relative to the PPS system ( Passenger Presence system). 

Heres what i have found so far  :

As per internet page : https://repairpal.com/obd-ii-code-b0081-first-row-center-seatbelt-load-limiter-deployment-control-subfault
towards the bottom of this internet page there are fault codes listed in association to the main fault code of B0081. :

Code B0081 technical details
There are often two-digit sub-codes associated with B0081. These codes indicate what type of circuit defect the control module has detected. Here is an example from a General Motors vehicle.
*Sub-code 00 indicates the sensing and diagnostic module (SDM) has detected a fault present in the passenger presence module.
Sub-code 3A indicates the sensing and diagnostic module (SDM) has determined the incorrect passenger presence system module is installed.
Sub-code 4B indicates the passenger presence system module is not calibrated.
Sub-code 5A indicates the passenger presence system module has lost communication with the SDM.

The fault codes reading out on my scanner are similar  :
0033-00, 0032-00, 0039-00, 004A-00, 0034-00.

So im guessing  it appears that there is a problem somewhere in the PPS system, even though the MAIN fault code B0081 does not show up on my scanner and the airbag lite is not on , nor the check engine lite is illuminated. If you read ahead, you will find that problems with the wiring, or the power to the PPS Module and the ground or that the PPS module needs programming. Can also be a loose PPS connector. Can also be : It's possible that one of the modules was previously replaced with an incorrect unit. ANY may be problems at hand.

How to diagnose and repair B0081 or its SUB Codes
Perform a preliminary inspection.
Sometimes B0081 can pop up intermittently. This is especially true if the code is a history code and not current. Clear the code and see if it returns. If it does, the next step is to perform a visual inspection. A trained eye can check for issues such as broken wires and loose connections. If a problem is found, the issue should be repaired and the code cleared. If nothing is discovered, check for technical service bulletins (TSBs). TSBs are recommended diagnostic and repair procedures put out by the vehicle manufacturer. Finding a related TSB can greatly reduce diagnostic time.
When code B0081 is set, it's also important to check the part #s on the SDM and PPS to ensure they're correct. It's possible that one of the modules was previously replaced with an incorrect unit.
Note: General Motors has a TSB for this problem which involves a loose PPS connector.
Check for other DTCs
The SDM will set code B0081 if the PPS module has a diagnostic trouble code (DTC) stored. Accessing these DTCS may indicate problems elsewhere that are affecting PPS module operation. Any additional DTCs should be addressed prior to diagnosing B0081.
Code B0081 often sets when the SDM cannot communicate with the PPS module. Before condemning the PPS module, the circuit between the SDM and PPS should be checked. This can be done using a digital multimeter (DMM). In addition, the PPS module's circuit should be checked for proper power and ground.
Check the modules
In some cases, the PPS module may be the problem. However, before condemning the module, ensure its software is up to date. It may be possible to program the module instead of replacing it.
In rare cases, the SDM may also be to blame. If replacing the PPS module doesn't work, the SDM probably needs to be replaced.

So, my questions  are :

has anybody seen PPS faults like this?  If so, what was your problem causing the codes?

 if there are sub fault codes with PPS, is the air bag system still operational ?

Is reprogramming of the PPS mudule common? 

If all that may be needed is reprogramming of the PPS module, what scanner can do it?

If reprogramming is done on the PPS module, what do you think it would cost?

I dont have schematics of the wiring between the PPS Module an the SDM (so i can trace it out and check for wiring problems)  . If obtained, can the wiring be rung out for continuity and or opens/shorts without affecting the air bag system?  

 Thank you all for your input, steve.
