I scanned my truck and got a P1780 code; " transmission control switch (O/D cancel) circuit out of self test range". I can't find what they are calling the " control switch", do they mean the control solenoid?

KOER DTC P1780: Check Transmission Control Switch Function

This DTC indicates Transmission Control Switch (TCS) was not cycled during KOER self-test. Possible causes are:
Faulty TCS
TCS Not Cycled During Self-Test
TCS Circuit Open Or Shorted
Faulty PCM
Turn ignition switch to ON position. Using scan tool, select TCS PID from PID/DATA MONITOR & RECORD menu. Cycle TCS switch. Then hold switch depressed for 3 seconds, then release switch. If TCS PID value switched from ON to OFF, then indicated ON when switch was depressed, repeat KOER ON-DEMAND SELF-TEST ensuring to cycle TCS.
