Tesla’s climate keeper feature helps you reduce your carbon footprint and provides a smooth driving experience. However, since it’s mostly dependent on software, being prone to malfunctioning shouldn’t be a surprise.
So, why does the “climate keeper unavailable due to a system fault” error message appear? The most common reason behind this is outdated firmware, which can be easily fixed through an update. Similarly, faulty sensors, glitches in the software, and a faulty climate keeper itself can contribute to this problem.
In this article, we will dig in depth into the reasons behind this problem along with their solution. Even though most of them can be fixed by oneself, some may not be possible since Tesla is quite a complicated space to work in. So let’s get started.
Climate Keeper Unavailable Due To System Fault: Reasons of the Error Message And Their Fixes

If you are experiencing issues with your Tesla’s climate keeper feature, you may encounter an error message. It will state that the system is unavailable due to a fault. This can be frustrating, especially during extreme weather conditions.
Well, it is supposed to be ensuring the safety, comfort, and efficiency of the vehicle during those harsh weather conditions. The reasons behind its failure aren’t rocket science but small glitches and bugs that can happen to any software or electronic device. So, let’s check them out with their solutions.
Outdated Firmware
One of the primary reasons behind this climate keeper unavailable problem is outdated firmware. Like any other device, the climate keeper feature is dependent on software to work with the hardware properly. To keep things in motion, Tesla provides updates to their users regularly.
These updates are meant to make the software and hardware more compatible with each other over time. So, in case you have missed the update, the feature doesn’t get to perform at its best. As a result, the climate keeper is unavailable due to a system fault pop-up.
The Fix:
To get rid of outdated firmware, you need to update it from your Tesla. To do this, follow the steps below.
- Connect your Tesla to the internet using Wi-Fi.
- Enter the vehicle’s settings menu and navigate to the “Software Updates” option.
- Select “Check for Updates” to see if there are any new software versions available.
- If an update is available, download it.
- Once completed, install the software.
- Restart your Tesla.

Faulty Temperature Sensors
The temperature sensors in your Tesla analyze the temperature outside and then run the data through an AI. Later on, the best outcome for the climate keeper feature is then decided and served.
However, faulty sensors may provide inaccurate readings, leading the climate keeper system to make decisions based on incorrect data.
Furthermore, the sensors may not be able to communicate with the AI and the climate keeper feature properly. As a result, the feature might even become unavailable for use.
The Fix:
You need to replace the temperature sensors for the feature to be usable again. Here’s how you can do it.
- Tesla vehicles are equipped with advanced diagnostic systems. So, use diagnostic tools to pinpoint the specific sensor that needs replacement.
- Refer to the vehicle’s manual to locate the faulty sensor within the vehicle.
- Disconnect the battery for your safety.
- Carefully remove the faulty temperature sensor from its housing.
- Place the new temperature sensor into the housing, ensuring it is securely fitted and connected properly.
- Reconnect the battery.
- Calibrate the sensors from settings.
Glitches In The Software
This is not the same as the previously mentioned outdated firmware issue, where an update can fix it. However, ensuring your firmware is the latest is the first step here. Assuming that your software is the latest, it can still run into some glitches.
Well, what glitches in the software means is that everything in your vehicle is fine, but the software has some errors in the code that it developed. As a result, you might come across various issues. They include malfunctioning displays, unresponsive controls, and even the climate keeper feature not being available.
The Fix:
You need to reset the software in your Tesla. To do that, you must own a Tesla diagnostic tool and then follow these steps:
- Put your Tesla into diagnostic mode by pressing and holding the “Talk to Tesla” button on your center console. Hold it for at least 10 seconds until the display screen turns black.
- Once your Tesla is in diagnostic mode, you will need to connect to the Tesla diagnostic tool using a USB cable.
- Navigate to the “Software” tab in the Tesla Service Tool and click on the “Reset” button.
- You will be asked to confirm that you want to proceed with the reset. Simply press “YES.”
