Body electrical system / Cruise control system - general information


1 Cruise control is available as an option on some models.

2 The cruise control system components are shown in the accompanying illustration (see illustration). The system is active at road speeds between 25 mph and 125 mph.

1 Speed control unit 2 Vehicle speed sensor (VSS) 3 Throttle valve actuator 4 Interrupt relay (vehicles with traction control system only) 5 Stop-light switch, brake and clutch pedaloperated disable switches 6 Driver’s controls (buttons on steering wheel)

3 The system comprises an electronic speed control unit with integral actuator and switches mounted in the engine compartment with a control cable connected to the throttle valve actuator, driver-operated switches, brake and clutch pedal switches, an indicator light, and a road speed sensor.

4 The driver-operated switches are mounted on the steering wheel, and allow the driver to control the various functions.

5 The vehicle speed sensor uses the speedometer cable drive pinion to generate pulses which are fed to the speed control unit.

6 The stop-light switch, brake pedal switch and (when applicable) clutch pedal switch are used to disable the cruise control system. The stop-light switch is activated when the brake pedal is applied gently, and the brake pedal switch is activated when the brake pedal is applied forcibly.

7 An indicator light on the instrument panel is illuminated when the system is in operation.

8 The following paragraphs describe brief removal procedures for the cruise control system components. The battery negative (earth) lead should be disconnected before commencing work (refer to Chapter 5, Section 1). Refitting is a reversal of removal.

9 Remove the steering column upper and lower shrouds, with reference to Chapter 10.

10 Remove the air bag module as described in Section 29.

11 Disconnect the multi-plugs, then unscrew the screws and remove the switch.

12 Remove the lower facia panel from under the steering column.

13 Disconnect the multi-plugs from the clutch switch, brake pedal switch and stoplight switch.

14 To remove the clutch and brake pedal switches, twist them anti-clockwise. To remove the stop-light switch, twist it clockwise (see illustration).

15 Refitting is the reverse of removal. To ensure correct operation of the brake pedal switches, reset the switch by fully extending its plunger (see illustration). Depress the pedal until the distance between it and the mounting bracket is as shown in Chapter 9, illustration 25.6. Hold the pedal in this position, clip the switch securely into position and gently raise the pedal to the at-rest position. This will automatically set the position of the switch.

Speed control actuator 16 Remove the air cleaner as described in Chapter 4.

17 Disconnect the actuator cable from the throttle linkage on the throttle housing, by releasing the inner cable end fitting from the segment and unclipping the outer cable from the bracket.

18 Unscrew the actuator mounting bolt, then slide the actuator out of the mounting pin holes.

19 Disconnect the multi-plug and remove the assembly.

20 Depress the actuating cable cap locking arm, and remove the cap by turning it anticlockwise (see illustration).

21 Gently raise the cable retaining lug by a maximum of 0.5 mm, and push the cable end out of the slot in the pulley.

22 When refitting, make sure that the cable end locks into the slot in the pulley.

23 To locate the cable cap onto the actuator pulley, keep the cable taut and in the pulley groove, and pull the throttle linkage end of the cable to draw the cable cap onto the pulley.

24 To refit the cable cap, keep the cable taut and the pulley still, then refit the cable cap tabs into the actuator slots; turn the cap clockwise until the locking arm locates on the locking stop. Note: Incorrect assembly of the cable onto the pulley may result in a high idle speed. Check that the throttle lever is in its idle position after refitting the actuator.
