P1701 · SubaruCruise Control Set Signal Circuit Malfunction AT

P1701 on Subaru vehicles means the transmission control module (TCM) has detected an abnormal signal on the cruise control set circuit, which is wired through the automatic transmission (AT) control system. The TCM expects a specific voltage pattern when the cruise control set button is pressed, and it flags this code when the signal is missing, stuck, or out of range.
