When you changed the seat did you recalibrate the passenger presence sensor?

Pretty sure theirs a calibration procedure after new sensor install. But the dealer should have done this you would think.

Which code are you getting or did GM tech not tell you?

Here is what I found on the sub ject, hope it helps.

Passenger Presence System Programming and Setup
Important: Before rezeroing the passenger presence system (PPS), the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults.

If the PPS is replaced or serviced, perform the rezeroing procedure for the PPS. Refer to Passenger Presence System Rezeroing for the rezeroing procedure.

Passenger Presence System Rezeroing
Introduction
The Inflatable Restraints Passenger Presence System (PPS) is a calibrated system that requires rezeroing anytime the seat cushion trim attachments have been removed or the PPS has been replaced. The procedures below are designed to assist in the rezeroing of the PPS. Before you start, read these procedures carefully and completely. For further information regarding the PPS refer to SIR System Description and Operation .

Important: The following procedures must be followed:

Read this procedure carefully and completely.
The PPS will not function properly if the PPS rezeroing procedure is not performed.
Perform the Diagnostic System Check - Vehicle after successfully completing the rezeroing procedure to ensure the system is functioning properly.
Passenger Presence System (PPS) Rezeroing Procedure
Important: Before rezeroing the PPS, the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS.

Important: When rezeroing the PPS, the instrument panel cluster (IPC), and Passenger Air Bag ON/OFF indicator will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults.

Empty the front outboard passenger seat.
Verify that all SIR and PPS components, connectors, and connector position assurances (CPAs) are properly connected and mounted.
Install a scan tool.
Turn ON the ignition, with the engine OFF.
Important: All SIR and PPS DTCs must be cleared before rezeroing the PPS. The presence of current or history DTCs will prevent the PPS from rezeroing and may set additional DTCs.

Use the scan tool in order to clear the SIR and PPS DTCs.
With a scan tool, request the PPS rezeroing procedure.
Initiate the PPS rezeroing procedure. The PPS will illuminate both PASSENGER AIR BAG ON and OFF indicators until the rezeroing procedure has been completed.
When the rezeroing procedure has been successfully completed, the PPS will display the current system status.

If the rezeroing procedure was unsuccessful, both PASSENGER AIR BAG ON and OFF indicators will alternate from no illumination to full illumination in 1 second intervals for 5 seconds. The PPS will treat an unsuccessful rezero attempt as a system fault.

If the rezeroing procedure was unsuccessful, repeat this procedure. Due to the communication status between the SDM and the PPS module, this procedure may have to be repeated until a successful rezero attempt has been achieved.
After the PPS has been successfully rezeroed, perform the Diagnostic System Check - Vehicle .
