Fix Tesla Cruise Control Unavailable

How to Fix Tesla Cruise Control Unavailable

One of the most common reasons Tesla Cruise Control becomes unavailable is faulty sensors. Tesla Cruise Control relies on various sensors to function properly, including cameras, radar, and ultrasonic sensors. If any of these sensors fail, Tesla Cruise Control will become unavailable.

I once had an issue with Tesla Cruise Control becoming unavailable due to a faulty sensor. I was driving on the highway when the Tesla Cruise Control suddenly turned off. I tried turning it back on, but it wouldn’t work. I pulled over to the side of the road and checked the sensors. The radar sensor was covered in dirt and debris. I cleaned the radar sensor with a damp cloth, and Tesla Cruise Control started working again. I was relieved that I could fix the problem myself without taking my Tesla to a service center.

In this article, I will discuss the most common reasons why Tesla Cruise Control might become unavailable, and I will provide solutions for fixing each problem. I will also share my personal experience with troubleshooting Tesla Cruise Control problems.

Why is my Tesla Cruise Control unavailable?

There are several reasons why Tesla Cruise Control is unavailable. Some of the most common reasons are:

  • Faulty sensors
  • Brake pedal switch issues
  • Camera failure
  • Faulty cruise control actuator
  • Software glitches

Now that you’re aware of some of the common causes of Tesla cruise control being unavailable, I’ll be giving solutions for each of these problems.

Let’s begin!

1. Faulty sensors

Solution 1: Clean the sensors.

Dirt and debris can block or obscure the sensors, preventing them from functioning properly. Like I said earlier in this article, I once had an issue with Tesla Cruise Control becoming unavailable due to a dirty radar sensor.

To clean the sensors, use a damp cloth to wipe them gently. Be careful not to use any harsh chemicals or abrasive cleaners, as this could damage the sensors. Once the sensors are clean, dry them thoroughly with a clean cloth.

Solution 2: Check the alignment of the sensors.

If, after cleaning your sensors, the control is still not responding, the next solution you can try is checking their alignment.

If the sensors are not properly aligned, they may not be able to accurately detect objects and obstacles. To check the alignment of the sensors on your Tesla, you will need a Tesla alignment target. You can purchase a Tesla alignment target from Tesla Service or from an online retailer.

Once you have a Tesla alignment target, follow these steps:

  1. Park your Tesla on a level surface.
  2. Place the Tesla alignment target in front of your Tesla, about 10 feet away.
  3. Open the Tesla Service menu. To do this, go to Controls > Safety & Security > Service Menu.
  4. Enter the service PIN. The default service PIN is 12345.
  5. Go to Diagnostics > Vehicle > Sensors.
  6. Select the sensor that you want to check the alignment of.
  7. Follow the instructions on the screen to align the sensor.

Solution 3: Restart your Tesla

I have noticed that whenever you restart your Tesla, you can sometimes resolve any minor software glitches that may be causing problems with the sensors. So, doing this can also help resolve

Solution 4: Update your Tesla’s software.

Tesla regularly releases software updates that include bug fixes and improvements to the sensors. To check for a software update, go to Controls > Software > Software Update.

If, after checking, you notice an update, here’s how I update my Tesla’s software, and you can do the same too:

  1. Park your Tesla in a safe location and connect it to Wi-Fi.
  2. On the touchscreen, tap Controls > Software > Software Update.
  3. If a software update is available, tap Download.
