The Brake Pedal sensor information is a bussed message to the Powertrain Control Module (PCM) from the ABS module. Use a scanner that can read all modules/codes and see if any ABS codes (Cxxxx) are logged in the ABS module.

What style of brake light switch is in your 2011 ... the switch or the pedal position sensor?
A brake pedal position sensor is used in place of the brake (or stop) lamp switch in some model years.

The ABS Module has detected a catastrophic failure on the CAN bus. (CAN = controller area network)

C211B-92
The Ignition Status reported on the CAN Bus does not match the state of the Ignition Input.

C006A-49
The Dynamics Sensor has indicated that it has detected an internal failure.

P0572
The PCM detects the Brake Switch is stuck in the low/On position.

The ABS module, the PCM and the Dynamics sensor are on the CAN Bus. The brake switch sends hardwired signals to the ABS module. The ABS module communicates with the PCM and BCM (body control module) on the status of the brake pedal.

Are there any BCM (Bxxxx) codes being logged?

Check the condition of the wiring harness/connectors of the brake switch (brake pedal sensor), ABS module, PCM, BCM and dynamics sensor.

The dynamics sensor (internal failure) may be affecting the CAN Bus.
Dynamic sensor (3) is located under the floor console.

Dark green & yellow (DG/YL) is the 5V supply line to the Brake pedal position sensor. If that wire is cut it will effect the operation of the brake pedal position sensor signal to the ABS module.
-Disconnect the BPP Sensor harness connector.
-Turn the ignition on.
-Measure the voltage of the (B237/Pin-A) BPP Sensor Supply circuit in the BPP Sensor harness connector.

I spliced it and connected the wired back and electrical taped it

Pursuit hack job?
It’s always nice that they can’t uninstall their gear correctly then sell it to people.
