Cruise Set/Coast

The scan tool displays ON or OFF. If the cruise control switch is in the ON position and the Set/Coast switch is activated, the scan tool displays ON. The switch, when in the ON position, sends a signal voltage to the TAC module, that signal is then sent to the PCM across serial data. If the Set/Coast switch is released the scan tool displays OFF.
