Possible Reasons for Lexus LS460 Cruise Control Not Working
There are several potential reasons why the cruise control on a Lexus LS460 may not be working. Some common causes include:
1. Mechanical Issues: If the cruise control is mechanical, a damaged cable or vacuum actuator could be the culprit.
2. Electrical or Sensor Problems: Issues with the control module, sensor, or throttle could also lead to cruise control malfunctions.
3. Clock Spiral Cable Failure: In some cases, the cruise control may stop working due to a failure of the clock spiral cable located on the steering wheel behind the airbag.
4. Diagnostic Findings: Some owners have reported ongoing problems with the cruise control, including issues with acceleration and downshifts, which have been diagnosed but not repaired.
Potential Solutions
If the cruise control on a Lexus LS460 is not working, it’s advisable to have a mechanic inspect the vehicle to determine the nature of the problem. Depending on the specific issue, potential solutions may include:
– Mechanical Repairs: If the issue is related to mechanical components, such as a damaged cable or vacuum actuator, mechanical repairs may be necessary.
– Electrical or Sensor Repairs: If the problem lies with the control module, sensor, or throttle, electrical or sensor repairs may be required.
– Clock Spiral Cable Replacement: In cases where the clock spiral cable is identified as the cause of the issue, replacing the cable may resolve the cruise control malfunction.
It’s important to consult with a qualified mechanic or Lexus dealer to diagnose and address the specific cause of the cruise control malfunction in a Lexus LS460.

You may want to change your adaptive cruise control settings, such as the following distance or maximum speed. Resetting the system allows you to start with default settings.
How much does it cost to fix cruise control?
A cruise control system can stop working due to (1) a mechanical problem (2) a blown fuse (3) a damaged speed sensor (4) a faulty brake pedal switch or (5) electrical problems. Repair costs can start at $100 and go beyond $500, depending on the affected part, labour costs, and the car brand and model.
How do you diagnose cruise control problems?
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.
Can a fuse cause cruise control not to work?
Blown Fuse
All electrical transmissions in a vehicle are enhanced and controlled by fuses. Once the engine control system detects a defect in the fuse and other electrical components, it sends a check engine warning light to the dashboard and eventually disables the cruise control system.
What sensor controls cruise control?
Speed and distance sensors.
ACC uses information from two sensors: a distance sensor that monitors the gap to the car ahead and a speed sensor that automatically accelerates and decelerates your car. ACC uses information from these sensors to adjust your speed and maintain the set distance from the car in front of you.
Why would my cruise control suddenly stopped working?
Since your car’s cruise control is part of an electrical system, it needs a fuse to function properly. A short circuit in this system can cause a fuse to blow, which means that the cruise control will suddenly stop working. Fortunately, replacing a blown fuse is a cheap and easy repair for any auto mechanic.
Why does my cruise control light come on but not engage?
Most likely the issue is going to be a failure with one or more cruise buttons or a wiring issue related to the clock spring. That outcome would indicate you brake pressure switch or brake pedal position switch is sensing the pedal is applied when it is not.
What to do if cruise control fails?
The majority of cruise control systems are made to turn off at low speeds, so simply slowing the car down can help you restore control. First Try to turn it off and if that doesn’t work then tap the brakes. If that fails put the transmission in neutral and get off the road.
Can you reset your cruise control?
If you notice that your speed fluctuates after setting it, your system may be malfunctioning. To determine if you have a problem, try resetting the system. To do this, turn the cruise control off by disengaging the switch in your car. Next, turn the system on again, set a speed, and reapply cruise control.
