How to Troubleshoot: Tesla After Update Won’t Turn On

Overview

If your Tesla won’t turn on after an update, there are a few things you can check to try to troubleshoot the issue.

Step 1: Check the fuses

The first thing you should do is check the fuses in your Tesla. There are a few different fuses that could be responsible for the issue, so it’s important to check them all.

To check the fuses, you’ll need to open the fuse box. The fuse box is located in the driver’s side footwell. Once you’ve opened the fuse box, you’ll need to find the fuses that are related to the electrical system.

The fuses that are related to the electrical system are typically labeled BAT, BTM, CHG, HV, and 12V. You’ll need to check each of these fuses to make sure they’re not blown.

If a fuse is blown, you’ll need to replace it with a new fuse that has the same amperage rating. You can find replacement fuses at most auto parts stores.

Step 2: Check the battery

If the fuses are all good, the next thing you should check is the battery. The battery in your Tesla is a lithium-ion battery, and it’s important to make sure that it’s properly charged.

To check the battery, you’ll need to use a voltmeter. You can find a voltmeter at most auto parts stores.

To use a voltmeter, you’ll need to connect the positive lead of the voltmeter to the positive terminal of the battery, and the negative lead of the voltmeter to the negative terminal of the battery.

The battery should have a voltage of between 12.6 and 13.2 volts. If the battery’s voltage is lower than 12.6 volts, it’s likely that the battery is discharged.

If the battery is discharged, you’ll need to charge it. You can charge the battery using the Tesla charging cable.

Step 3: Check the 12V auxiliary battery

In addition to the main battery, your Tesla also has a 12V auxiliary battery. This battery is used to power the car’s electrical system when the main battery is not in use.

The 12V auxiliary battery is located in the trunk of the car. To check the battery, you’ll need to open the trunk and locate the battery.

The 12V auxiliary battery is a standard lead-acid battery. You can check the battery’s voltage using a voltmeter.

The battery should have a voltage of between 12.6 and 13.2 volts. If the battery’s voltage is lower than 12.6 volts, it’s likely that the battery is discharged.

If the battery is discharged, you’ll need to charge it. You can charge the battery using a standard 12V car battery charger.

Step 4: Check the software

If the fuses, battery, and 12V auxiliary battery are all good, the next thing you should check is the software.

Tesla regularly releases software updates for its cars. These updates can fix bugs and improve performance.

If your Tesla won’t turn on after an update, it’s possible that the update has caused a problem.

To check the software, you’ll need to connect your Tesla to a Wi-Fi network. Once your Tesla is connected to Wi-Fi, you’ll need to open the Tesla app.

In the Tesla app, you’ll need to go to the Settings tab. Then, you’ll need to select Software.

The software update status will be displayed at the top of the screen. If there is an update available, you’ll need to install the update.

Step 5: Reset the car

If you’ve checked all of the above and your Tesla still won’t turn on, you can try resetting the car.

To reset the car, you’ll need to hold down the brake pedal and the two scroll wheels for 10 seconds.

Once you’ve held down the brake pedal and the two scroll wheels for 10 seconds, the car will reset.

After the car has reset, try turning it on again.

Step 6: Take your car to a Tesla service center

How to Prevent Tesla After Update Won’t Turn On in the Future

Tesla vehicles are equipped with over-the-air (OTA) software updates that can improve performance, fix bugs, and add new features. While these updates are generally safe and reliable, there have been a few instances where they have caused problems, such as preventing a Tesla from turning on.

If your Tesla won’t turn on after an update, there are a few things you can try to fix the problem.

1. Reset the MCU

The MCU (media control unit) is the computer that controls the infotainment system in your Tesla. If the MCU is not functioning properly, it can prevent the car from starting. To reset the MCU, follow these steps:

1. Turn off the car and wait 5 minutes.
2. Press and hold the brake pedal and the accelerator pedal at the same time.
3. While holding the pedals down, turn the key to the On position.
4. Release the pedals and wait for the car to start.

2. Perform a hard reset

A hard reset is a more drastic way to reset the MCU. It will erase all of your settings and preferences, so be sure to back them up before you proceed. To perform a hard reset, follow these steps:

1. Turn off the car and wait 5 minutes.
2. Press and hold the brake pedal and the 2 button on the steering wheel at the same time.
3. While holding the pedals down, turn the key to the On position.
4. Release the pedals and wait for the car to start.

3. Take your Tesla to a service center

If you have tried the above steps and your Tesla still won’t turn on, you should take it to a Tesla service center. The technicians there will be able to diagnose the problem and fix it.

Preventing Future Problems

There are a few things you can do to prevent future problems with Tesla software updates:

Make sure your car is up to date with the latest software. Tesla regularly releases software updates that fix bugs and improve performance. By keeping your car up to date, you can help reduce the chances of encountering problems.
Back up your settings and preferences before updating your car’s software. If you do encounter a problem with a software update, you can restore your settings and preferences from a backup.
Be aware of the risks of OTA updates. OTA updates can sometimes cause problems, so it’s important to be aware of the risks before you install one. If you’re concerned about the risks, you can always decline to install an update.

By following these tips, you can help prevent problems with Tesla software updates and keep your car running smoothly.
