Cruise Control Switch

Cruise control switch provides PCM with 3 separate inputs. ON/OFF switch input informs PCM that cruise control system has been activated. SET/COAST switch input informs PCM that set vehicle speed has been selected, or if depressed will decelerate until switch is released. RESUME/ACCEL switch input informs PCM that a previously set speed has been selected or, if depressed, will increase speed until released. PCM uses these inputs to control cruise control servo.
