Speed Control

The vehicle speed control consists of the following components

1. brake pedal position (BPP) switch
2. deactivator switch
3. instrument cluster
4. powertrain control module (PCM)
5. speed control actuator cable
6. speed control actuator switch
7. speed control actuator

Refer to SYSTEM WIRING DIAGRAM for schematic and connector information.

Scheme 1

Principles of Operation

The speed control system is designed to maintain vehicle speed above 48 km/h (30 mph). After the ON switch is depressed, depressing the SET/ACCEL switch will activate the speed control actuator. To increase a set speed, either depress and hold for continuous acceleration, or momentarily tap the SET/ACCEL switch for 1.6 km/h (1 mph) acceleration increments. To decrease a set speed, depress and hold the COAST switch until the target speed is reached, or momentarily tap the COAST switch for 1.6 km/h (1 mph) deceleration increments. When the speed control system has been disabled by tapping the brake pedal, the RESUME switch can be depressed and the vehicle will return to the original set speed if the vehicle is traveling over 48 km/h (30 mph) and the OFF switch has not been depressed.

Note. The deactivator switch is provided as an additional safety feature. Normally, when the brake pedal is depressed, an electrical signal from the brake lamp circuit to the speed control actuator will deactivate the system. Under increased brake pedal effort, the deactivator switch will open and remove power to the speed control actuator, releasing the throttle independently of the speed control actuator.

Note. The clockspring provides the electrical interface between the steering column wiring and the speed control actuator switches in the steering wheel.

The inputs to the speed control actuator are

1. powertrain control module (PCM)
2. speed control actuator switches
3. brake pedal position (BPP) switch
4. deactivator switch

The outputs of the speed control actuator are

1. speed control indicator (electronic cluster)
2. speed control actuator cable controlling the throttle position

Inspection and Verification

Note. If any concerns are noted with the speedometer, stoplamps or horn, address those concerns by referring to their associated articles before continuing speed control diagnosis.

Scheme 2

1. Verify the customer concern by operating the speed control system.
2. Visually inspect for obvious signs of mechanical and electrical damage.
3. If the fault is not visually evident, verify the symptom and refer to the «SYMPTOM CHART»(/ford/crown-victoria/ii-1997-2011/remont/cruise-control-systems/#cruise-control-system) .

Self-Test Diagnostics - Electronic Cluster

1. Enter Self-Test Diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator on the instrument panel will flash once to indicate that speed control module entered the diagnostic mode. Five additional flashes at this point indicates a defective speed control actuator. Release the OFF switch.
2. Press the remaining switches in this sequence: ON, RESUME, COAST and SET/ACCEL. If the "ON" switch is not depressed within five seconds after entering the diagnostics mode, the module times out and the procedure must be started over. The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence immediately after the indicator light goes out for the previous switch.
3. A lamp flash with the last button (SET/ACCEL) indicates that the STATIC test passed. If the lamp does not flash with the last button and there are no additional flashes of the lamp, the switch is defective. If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for trouble codes: 2 flashes: BPP defective, circuit is defective, brake applied. 3 flashes: Deactivator switch is open or circuit defective.
4. Immediately after the static test, the speed control actuator carries out a dynamic test by automatically actuating the throttle lever from 8 mm (0.32 in) to 10 mm (0.4 in) of travel from the idle position. During the dynamic throttle pull, observe throttle movement to witness any binding or sticking of the actuator cable and proper connection of actuator cable to throttle lever. Make sure the throttle returns back to idle position.
5. Return ignition switch to the OFF position and proceed to the «SYMPTOM CHART»(/ford/crown-victoria/ii-1997-2011/remont/cruise-control-systems/#cruise-control-system) .

Cable Adjustment

Note. Crown Victoria and Grand Marquis shown, Marauder is similar.

Scheme 23

Scheme 24

1. Remove the retaining clip from the speed control actuator cable adjuster.
2. Pull on the speed control actuator cable to take up slack, then back off at least one notch so there is approximately 3 mm (0.118 in) of slack in the speed control actuator cable.
3. Insert the speed control actuator cable retaining clip and snap into place.
4. Verify that the throttle linkage operates freely and smoothly.

Switch Adjustment - Deactivator

Note. For correct adjustment, the deactivator switch must be removed and reinstalled.

For additional information, REFER to SPEED CONTROL DEACTIVATOR SWITCH .
