Ford Focus Service Manual: Description and Operation

The cruise control system consists of the following components:

• Clutch pedal cruise control deactivator switch (manual transaxle only)
• Electronically-controlled throttle body
• Cruise control deactivator switch (part of the stoplamp switch)
• Cruise control indicator
• Cruise control switch
• Stoplamp switch
• PCM

The cruise control system is controlled by the PCM. The cruise control system is designed to maintain a selected vehicle speed between 37 km/h (23 mph) and the maximum limited vehicle speed. The cruise control system is controlled by the steering wheel mounted switches (ON, OFF, SET+, SET-, and RESUME), the stoplamp switch, the clutch pedal cruise control deactivator switch (manual transaxle), and the cruise control deactivator switch (part of the stoplamp switch). The steering wheel mounted switches are hardwired to the PCM through the clockspring.

During normal driving, the vehicle speed may vary slightly from the set speed due to road conditions. The vehicle speed may vary or fluctuate when driving up and down a steep hill. If the vehicle speed decreases more than 16 km/h (10 mph) below the set speed, the cruise control disengages.

For manual transaxle vehicles, it is normal for the engine rpm to increase slightly and then drop off slowly when the clutch pedal is applied during operation.

When a MyKey™ is used and the MyKey™ max speed limiter is turned on, the vehicle speed cannot be set to exceed 130 km/h (80 mph).
