DTC codes / P05xx · Vehicle speed, idle control and auxiliary inputs / P0567
P0567 indicates that the cruise control module has detected a problem with the resume signal circuit, which is the command that tells the system to return to the previously set speed after a cancel or brake event. The computer monitors the voltage or signal from the resume switch and sets this code when the signal is out of expected range or inconsistent with other inputs.
The vehicle remains safe to drive because the cruise control system simply disables the resume function, but you should avoid using cruise control until the fault is repaired to prevent unexpected behavior. Have the system diagnosed at your convenience, as the issue will not strand you.
