Cruise Control Module: Description and Operation
OPERATIONThe module will interpret the position of the servo, the position of the control switches and the output of the speed sensor. In response to these inputs, the module electrically signals the opening or closing of the vent and vacuum solenoid valves in the servo.
The module is mounted on the dash support bracket at the right side of the steering column, but is integral with the ECM on some models with certain engines.
