The Full Accessory Power Active warning is an indication that helps you determine whether you have enough charge in your vehicle’s battery to be able to use the accessories without losing any electrical power or not. It’s, in fact, a good sign to see come up on your vehicle.

You can easily disable the feature to save battery from draining, and it’s even recommended to use only when necessary. The function allows certain electric functions to work after you’ve turned off the ignition in your car.

While the systems that are powered with the function vary based on your vehicle’s make and model, some examples involve power windows, radio, seat warmers, and more. The feature can be really helpful in certain situations, such as when waiting for someone while listening to the radio.

However, since it works with your car battery’s power, it is essential to turn it off when not required.


Accessories Active with The FAP Feature

While the accessories that remain active with the Full Accessory Power feature can vary depending on the make and model of the vehicle, in general, systems that are commonly kept active when FAP is engaged include:

  • Radio: Many people tend to keep the radio powered on even after they’ve turned off the ignition, allowing them to enjoy their favorite songs on the go. This is a convenient feature for those who like to listen to music or other audio programs while they wait in the car.
  • Power Windows: It also helps you keep the power windows of your car active, thereby allowing you to easily roll them up when required. 
  • Automatic Climate Control: The FAP feature can also keep the automatic climate control running even after the car is turned off. The feature comes really handy when you’re in hot areas as it allows you to stay comfortable regardless of the external environment. 
  • Interior Lights: The FAP feature can also keep the interior lights powered on, which is useful if you need to look for something inside of the vehicle, especially in dark areas or if you’re parking in a dark area. 
  • Auxiliary Power Outlets: some cars have this feature to keep the power outlets active, like USB charging ports, which can be useful to power other devices while waiting in the car.

LCD screens, powered seat adjusters, and various other electrical features stay working with the FAP feature, and it can vary depending on the vehicle, but they are also common to be active when the FAP feature is on.

Here’s how you can activate and deactivate the Full Accessory Power Active feature in your car:

Where To Find the FAP Feature?

The location of the FAP feature can vary depending on the make and model of the vehicle. The feature is typically found on the dash or close to the ignition switch. It can be represented by a button or a switch.

Tips To Make the Most Out of The FAP Feature
