Speed surges while cruise control is engaged One of first symptoms most commonly associated with a problematic cruise control vacuum reservoir is the speed surging while the cruise control is engaged.

Why is the vacuum reservoir important in a cruise control system?

The cruise control vacuum reservoir is a very important component to vehicles that use them as part of their cruise control system. It supplies the cruise control system with the vacuum necessary for it to operate, and without it, the system cannot function.

How does a cruise control module detect speed?

The only way your cruise control module is going to know how fast the vehicle is moving is if the vehicle speed sensors feed this information to it. If the module cannot detect the speed because of faulty speed sensors, then the cruise control system will automatically deactivate.

Why does cruise control not work when brake light is blown?

Brake Lights – In some systems, cruise control is disabled when a brake light is blown. Aftermarket lighting, such as LED brake light conversion, might trick the CCM into thinking a brake light is blown, as LED bulbs draw less current than incandescent bulbs.

Cruise control has been around since the late 1950s. There was a time when you could only find this convenient feature in a few model vehicles. Nowadays, it seems like virtually every model vehicle on the road has a cruise control feature.

How does an adaptive cruise control system work?

Adaptive cruise control systems, sometimes called “smart” cruise, use radar or laser detection to maintain safe distances from vehicles ahead.

The cruise control can’t see them either. Ford’s manual states: “When you are going downhill, your vehicle speed may increase above the set speed. The system will not apply the brakes. Change down a gear to assist the system in maintaining the set speed.” That hill warning is there because the car companies are “worried about runaway vehicles.”

Where does the cruise control signal come from?

The cruise control takes its speed signal from a rotating driveshaft, speedometer cable, wheel speed sensor from the engine’s RPM, or from internal speed pulses produced electronically by the vehicle. Most systems do not allow the use of the cruise control below a certain speed – typically around 25 mph (40 km/h).
