The cruise control set/coast switch is an input to the powertrain control module (PCM). The PCM uses the cruise control set/coast switch signal circuit in order to detect when the driver has requested to set the vehicle speed or to decelerate the vehicle speed. The PCM detects a voltage signal on the cruise control set/coast switch signal circuit when the switch is applied. This DTC sets if the PCM senses voltage on the cruise control set/coast switch signal circuit for longer than 90 seconds.
