Signs of a Bad or Failing Speed ​​Governor Assembly

Common symptoms include cruise control not turning on or maintaining the same speed, and the cruise control light staying on even when not activated.

Nearly 130 million motorists depend on their cruise control or speed control hub to drive on US highways daily, according to the US Department of Transportation. Cruise control not only gives drivers a break from the constant pressure on the throttle, but it can also improve fuel economy due to the absence of throttle vibration, speed up driving control, and is one of the most reliable electrical components in modern cars. However, sometimes the speed governor assembly shows signs of failure or failure.

Below are a few warning signs you should be aware of that can help you diagnose if there is a problem with your cruise control.

1. Cruise control does not turn on

One of the easiest ways to know that a problem exists with your speed control box is when it simply won't turn on when you try to activate the system. Each car manufacturer has different procedures for how cruise control should be engaged. However, if you followed the instructions and he still doesn't want to cooperate, that's a good sign that something is wrong with the device and should be repaired by a certified mechanic.

Some of the potential issues that can affect the ability of cruise control to engage include:

• The transmission (on an automatic transmission) is in neutral, reverse, or low gear, or sends a signal as such to the CPU.
• Clutch pedal (on a manual transmission) is pressed or released or sends this signal to the CPU
• Your vehicle is moving at less than 25 km/h or faster than allowed by the settings.
• Brake pedal depressed or brake pedal switch defective
• Traction control or ABS active for more than two seconds
• The CPU self-test has detected a malfunction in the speed control unit.
• Blown fuse or short circuit
• Faulty VSS or vehicle speed sensor
• Throttle Actuator Malfunction

2. The cruise control indicator stays on even if it is not activated.

There are two separate lights on the dashboard to indicate that the cruise control is working. The first light usually says "Cruise" and is an indicator light that comes on when the cruise control switch is in the "ON" position and is ready to be turned on. The second indicator usually says "SET" and informs the driver that the cruise control is activated and the vehicle speed is set electronically.

When the second light is on and you have turned off the cruise control manually, it indicates that there is a problem with your speed control assembly. Normally this warning light stays on when the fuse is blown or there is a communication failure between the cruise control and the onboard processor. If this happens, you may need to replace the speed control assembly.

3. Cruise control does not maintain a constant speed

If you have set cruise control and notice that your speed keeps dropping or increasing while driving on a flat road, this could also indicate that your system is at fault. This problem is usually caused by a problem with the throttle actuator or vacuum actuator on older vehicles with an electromechanical cruise control system.

One way to test this while driving is to disable cruise control by turning off the switch, usually located on the steering wheel, flipping the switch back to the "on" position, and re-enabling cruise control. Sometimes simply resetting the cruise control switch will reset the system. If the problem occurs again, it is very important to report the problem to a certified mechanic so that it can be fixed as soon as possible.

A speed control node or cruise control may seem like a luxury, but if there is a problem with this system, it can potentially become a safety issue. There have been many accidents on U.S. highways due to cruise control systems acting or not disengaging, resulting in sticky throttles. If you have problems with cruise control, do not delay and do not delay, but contact AvtoTachki as soon as possible so that a professional mechanic can come to diagnose and repair the unit.
