I am sorry that you have not been helped yet. I just came online and saw your question
I may be mistaken but the sensor in the rear differential is the abs speed sensor and if it is faulty, it will turn on the abs warning light.
I need to get the 17 digit vin number to pull the wiring schematics to be able to help you
we are missing a digit from the vin - you have 16 and it should be 17 digits
As I believed, the rear diff sensor is solely for the abs and for speedometer as well.
This is due to either a faulty parking brake applied(pba) switch, or break in the wire to it. It is located at top of the parking brake pedal assembly(see attached)
Ok, you didnt mention that you had checked that switch, only that you checked the brake pedal switch which is not the same as the parking brake applied switch.
Not sure what else would cause it so I will opt out and see if another expert can help

Super, open the link below.
I need you to remove the cluster, and unplug connector B. Now OHM test pin 11 light green/red to ground. You should get an open circuit, is that the result you get?
Thanks, ***** ***** have preferred to see OL reading with it released. I am wondering if that small amount of continuity is enough to trigger the audible warning the light. Can you remove this wire and pin from the connector, plug the cluster back up and test it.
So with the wire removed the parking light and audible alarm are gone. unplug the parking brake switch, if the ohms now drop to zero, then the switch is bad. If they remain giving a reading then the wire is damaged.
Can you do the diag steps below for no turn signals?
The parking brake wire goes to the:
parking brake switch
park brake relay
We need to unplug each and see if you can find what is causing this wire to have continuity to ground.
When you pulled this relay did the parking brake light go out, no more audible tone and the cruise control now works?
Just no DRL operation?
View the link below, was it the park brake relay you removed?
Did I understand right you replaced this relay and the continuity you had prior remained?
Can you test the cruise?
Your next option is, I can help you bypass this relay or we can do much more wire testing.
