Calais L4-151 2.5L VIN U TBI (1989)
Cruise Control Module: Description and Operation
The cruise control 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 cruise control 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.
