1. 1

   Inspect the PTO 540 button on the control console/armrest for physical damage, sticking, or liquid ingress

2. 2

   Remove the console trim to access the back of the switch. Disconnect the switch and inspect the connector pins for corrosion, pushed-out pins, or loose wires

3. 3

   Check the wiring harness leading from the switch to the TRANS1 module for rub points, open circuits, or shorts to ground

4. 4

   Using a multimeter, test the continuity of the PTO 540 button across its pins while pressing and releasing it. If the resistance does not change smoothly or shows an open circuit when closed, the switch has failed internally
