Cruise Control System

The cruise control system on the diesel engines consists of the following components:
^ The Powertrain Control Module (PCM)
^ The electronic throttle control system
^ The Vehicle Speed Sensor Buffer (VSSB)
^ The multifunction lever
^ The brake release switch

The PCM receives commands from the multifunction lever. The PCM also receives vehicle speed information from the VSSB. The PCM sends information to the electronic throttle control system in order to control vehicle speed based on these input commands and vehicle speed.
