CRUISE CONTROL SYSTEM
Q
Operation
• The cruise control system will maintain a desired vehicle speed under normal driving conditions. The
system may be used to cause the vehicle to accelerate, coast, and resume the desired speed when
cruise control is temporarily canceled.
• The cruise control module receives input from the brake switch, cruise control main switch, cruise
control switch, clutch switch (MTX), transaxle range switch (ATX), and vehicle speedometer sensor.
The cruise control module sends output signals to the cruise actuator. The cruise actuator operates
vacuum valves, which adjust the accelerator linkage, to control the vehicle speed based on the input
signals.

Vehicle speedometer sensor AC signals from vehicle speedometer sensor (in transaxle) are transform ed to
DC signals at speedometer. These speed signals are sent to cruise control
module.
Cruise control module
