The cruise control resume/accel switch is an input to the powertrain control module (PCM). This allows the PCM to control and hold a requested speed. The cruise control resume/accel switch sends an ignition positive voltage signal to the PCM when the switch is applied. This DTC sets if the PCM senses a voltage on the resume/accelerate switch signal circuit when voltage is not expected
