Symptoms of a Bad or Failing Cruise Control Vacuum Bleed Switch
- Cruise control does not disengage when pedal is pressed.
- Cruise control disengages on its own intermittently.
- Hissing noise coming from under the dash.
What does cruise control do in a car?
Cruise control is a feature that helps reduce such fatigue drivers would feel while driving a long distance. The system imitates the way human drivers drive. But instead of pressing the accelerator pedal, it uses an actuator to control the throttle and helps your car continue cruising at the same speed.
Where is the cruise control module?
The module is located under the left side of the instrument panel inside the vehicle. Cruise control does not disengage when pedal is pressed.
What module controls the cruise control?
Cruise Control Components An electronic control module controls most of today’s cruise control systems. It can be a standalone or integrated into the PCM or BCM. The module uses several inputs to control operation and vehicle speed. These are the components found on most cruise control systems.
Where is the cruise control fuse?
The cruise control fuse is normally found in the fuse panel located below the steering wheel. Remove the cover of the fuse panel and locate the fuse for the cruise control using the fuse diagram on the fuse panel.
Can cruise control malfunction?
When the fuse of for the cruise control blows, the cruise control will stop working altogether. A vehicle’s cruise control may stop working if the vacuum actuator has stopped working or if there is damage to the vacuum hoses. The system may also fail if the cable linking the actuator to the throttle is broken.
Does cruise control use more gas?
Generally speaking, yes. Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.
Can you brake on cruise control?
After the cruise control is set, you may remove your foot from the accelerator. To decelerate, either tap the appropriate button on the cruise control system or quickly apply the brake. As a safety precaution, almost every model of car will deactivate the cruise control as soon as the brake is applied.
How do you activate cruise control?
To use Cruise Control, turn it on first by pressing the button on the end of the control stalk behind the lower right side of the steering wheel. The green cruise control icon will appear in the instrument display to show the system is ready. Then accelerate to the speed you want, and press the stalk down to set it.
How do I check cruise control?
A quick way to diagnose this is to try holding the brake pedal up with the top of your left foot at the same time as you are engaging the cruise control while on a test drive. If the cruise control tries to set, then the brake switch will most likely need to be adjusted. Adjustment of the brake switch is very common.
How does the cruise control module work in a car?
Cruise Control Module Function 1 Your desired speed is recorded by the module. 2 The module compares real-time speed sensor data to your settings. 3 The cruise control module reads the differences between the two values. 4 Electronic signals are sent to the throttle actuator to tell it to open or close, adjusting your vehicle’s speed.

Which is the brain of the cruise control system?
Touch device users, explore by touch or with swipe gestures. The cruise control module is the brain of the entire cruise control system. If your cruise control does not hold the same speed on a flat road, or does not engage at all, there might be a problem with the cruise control module.
Where does the cruise control signal come from?
When pressing the R/A (resume/accelerate) on the control switch, ignition positive voltage is applied to the resume/accelerate switch signal terminal of the cruise control module. The cruise control module receives a vehicle speed signal input from the powertrain control module (PCM). In operation, the voltage varies between 0 V and 5 V.
What does the are / a on the cruise control switch do?
When pressing the R/A (resume/accelerate) on the control switch, ignition positive voltage is applied to the resume/accelerate switch signal terminal of the cruise control module. The cruise control module receives a vehicle speed signal input from the powertrain control module (PCM).
