How To Keep Accessory Mode On: Lever Lose Power

Accessory mode is a popular feature in cars that allows drivers to use electrical components like the radio or air conditioning without starting the engine. 

However, this feature can sometimes be frustrating when it automatically turns off after a certain period, leaving you without power for your devices or entertainment. 

In this article, we’ll share some tips and tricks on how to keep accessory mode on in your car, so you can enjoy all the electrical components without worrying about them turning off. 

From using a battery pack to keeping the ignition switch in a certain position, we’ve got you covered. Let’s get started!

What Is Accessory Mode For?

Accessory mode is a function that provides power to certain electrical components of a vehicle while the engine remains off. 

It allows drivers to use features such as the radio, air conditioning, and interior lights without fully turning on the engine, which helps to conserve the car’s battery life. 

Accessory mode can be particularly useful when the car is parked for a long period, as it allows the driver to use these features without running down the battery. 

Additionally, it can be used to test specific systems or components without having to start the engine, such as the car stereo or interior lights. 

Overall, the accessory mode is a helpful feature that enables drivers to maximize their car’s electrical capabilities while saving energy and maintaining the car’s battery health.

Is Accessory Mode Bad For Your Car

Accessory mode itself is not bad for your car, but it can potentially damage your car’s battery if used for an extended period without the engine running. 

Using the radio, air conditioning, or other electrical components in accessory mode for too long can cause the battery to drain and eventually die, especially if the battery is old or weak.

In addition, attempting to manipulate the electrical system to keep the accessory mode on for an extended period or trying to activate the accessory mode without a key can damage the car’s electrical system.

Therefore, it is essential to avoid using the accessory mode for prolonged periods and consult a professional if you encounter any issues. 

Remember, using accessory mode sparingly and correctly should not damage your car.

Does Accessory Mode Drain Battery?

Accessory mode does have the potential to drain a car’s battery if it is used for an extended period without the engine running. This is because the electrical components, such as the radio and air conditioning, are powered by the car’s battery in accessory mode. 

However, the rate at which the battery is drained depends on various factors, such as the age and condition of the battery and the specific electrical components being used in accessory mode. 

In general, using accessory mode for a short period should not have a significant impact on the battery’s health, but it is always best to turn off all electrical components and switch off the ignition completely when not in use to avoid any unnecessary battery drain.

How To Keep Accessory Mode On

Below are some guidelines in bullet point form for keeping the accessory mode on.

  • Turn the ignition key to the “accessory” position, which is usually one click counter-clockwise from the “off” position.
  • Press and hold the start button without depressing the brake pedal to turn on accessory mode on cars with push-button ignition.
  • Use a battery charger or jump starter to power the car’s electrical components if the battery is low.
  • Check the car’s owner’s manual for specific instructions on how to keep accessory mode on for a prolonged period.
  • Install an aftermarket accessory mode switch or relay that can be used to control power to certain electrical components while the car is off.
  • Use a multimeter to check the voltage of the car’s battery and make sure it has enough power to support the electrical components used in accessory mode.
  • Start the engine and allow it to run for a few minutes to recharge the battery if it has been used in accessory mode for an extended period.

How To Put Car In Accessory Mode Without Key

Amazingly, it is possible to put a car in accessory mode without a key using a few methods, although the exact approach will depend on the car’s make and model.

One way is to use a remote starter to activate the car’s electrical system without the key. Another method is to connect a wire to the accessory circuit and ground it to activate the accessory mode.

Additionally, some newer cars have push-button ignition systems that allow drivers to turn on the accessory mode without the key. In this case, press and hold the start button for a few seconds without depressing the brake pedal to activate the accessory mode.

However, it is essential to note that these methods may not be legal or safe, and may also cause damage to the car’s electrical system if not done correctly.

What to Do If Your Battery Dies In Accessory Mode?

If your car battery dies while in accessory mode, the first thing to do is to turn off all electrical components to prevent further battery drain. 

Then, try starting the engine to recharge the battery. If the battery is completely dead, it may be necessary to jump-start the car or use a battery charger to bring it back to life.

If none of these methods work, it may be time to replace the battery. It’s crucial to check the battery’s age and condition regularly and replace it if it shows any signs of weakness. 

Additionally, avoid using accessory mode for prolonged periods, as it can drain the battery and cause it to die, especially if the battery is old or weak.


Final Thoughts

Accessory mode is a convenient feature in cars that makes it possible to use electrical components without running the engine. By following the tips and tricks we’ve provided in this article, you can keep accessory mode on for extended periods and enjoy your car’s electrical components without any interruptions.
