1. 1

   Check the park brake solenoid coil for physical cracks or electrical shorts.

2. 2

   Test the park brake pressure switch to verify if it is stuck closed or reading out of range, falsely reporting high pressure to the controller.

3. 3

   Inspect the wiring harness leading to the transmission control valves and park brake solenoids for chafing or shorts to power.
