DTC B2610
Circuit Description:
The body control module (BCM) receives a variable voltage signal from the instrument panel (I/P) dimmer switch requesting to illuminate the illumination lamps to a desired intensity. When this occurs, the BCM directly sends a variable voltage based on the I/P dimmer switch position on the instrument panel lamps dimming supply voltage circuit, controls illumination lamps dimming control circuit, and the LED dimming signal circuit. Voltage for the instrument panel lamps dimming supply voltage circuit, controls illumination lamps dimming control circuit, and the LED dimming signal circuits is from the TBC 2 A fuse in the instrument panel fuse block directly through the BCM to these circuits.
Conditions for Setting the DTC:

Conditions for Setting the DTC:
- The battery voltage must be between 9.0-16.0 volts.
- The controls illumination lamps dimming control circuit is open, shorted to ground, or shorted to voltage.
- The instrument panel lamps dimming supply voltage circuit is open, shorted to ground, or shorted to
- voltage.
- There is a loss of the instrument panel fuse block TBC 2 A battery supply voltage to the BCM for 1
- second.

Thank you @jsbihn here's some info:-
DTC's:-
Somehow these coded are maybe linked together, note that I/P Fuse Block feeds both DDM and PDM fuses and Unlock/Lock + LiftGate Relays, but that would be a major short or open circuit, however it would account for loss of comms to both door modules.
All depends on where your mysterious short was, guess we'll never know...
DTC's:-
U1160 Lost Communication with Driver Door Module (DDM)
U1161 Lost Communication with Passenger Door Module (PDM)
B2610 Passenger Compartment Dimming 1 Circuit BCM
Conditions for Setting the DTC B2610
• The controls illumination lamps dimming control circuit is open, shorted to ground, or shorted to voltage.
• The instrument panel lamps dimming supply voltage circuit is open, shorted to ground, or shorted to voltage.
• There is a loss of the instrument panel fuse block TBC 2A battery supply voltage to the BCM for one second.
• An open in the TBC 2A fuse will cause the BCM to set the following DTCs:
- B0951
- B2610
- B2625
U1160 & U1161
• An intermittent open between the inoperative module and a star connector may cause this code to set.
• A poor connection at the inoperative module or a star connector may cause this code to set.
• An intermittent open in a star connector may cause this code to set.
• An improperly powered module may cause this code to set.
As I was looking into this I see hummerz also responded.U1161 Lost Communication with Passenger Door Module (PDM)
