Does your Ford Fusion, Edge, F150, Explorer, Mustang, or any other model have the capability to turn off the full accessory power active mode? Depending on your experience, this mode may cause difficulty starting your vehicle. It is no longer a concern for you.
Upon clearing the accessory mod with your own hands, I will guide you on how to turn off the accessory modification. This mode serves a number of purposes, and it is first necessary for us to understand what it is, its features, and its purpose.
What are the Ford vehicles’ full accessory powers?
Technology has improved the functionality of modern vehicles and made them more convenient for the user. Users get helpful and advanced features through it, which helps enhance their experience.
Full accessory power is one of the features that Ford offers. A reduction in wear and tear will improve fuel efficiency, reduce noise, and extend the life of engine components.
While the engine of your vehicle is not running, this message will appear on the dashboard. Without using the engine, passengers can switch on the radio, open the windows, and turn on the lights.
Electricity can be used without starting the engine for charging mobile phones or laptops.
If Ford’s full accessory power is on, how do you turn it off?
By following the steps below, you can turn off accessory mode in a simple and straightforward manner:
- A quick rest of a few minutes or half an hour is all you need to do for your vehicle.
- In addition, make sure you do not press the brake pedals while pressing the start/stop button.
- Click on the engine start/stop button after pressing the brake paddles.
- After pressing the brake paddles, turn the key to the first position on vehicles equipped with the manual essential function.
Last but not least, I hope you started your Ford car after you took it out of accessory mode. In addition, you can watch the video below to get a better idea of what to do.
Factors contributing to accessory power active messages
This accessory message on the dashboard may be caused by the following possible causes:
- Battery issues
- Software glitches
- Electrical issues
- Ignition issues
- Issues with the electric control unit (ECU)
1. Battery Issues
The accessory power active message can be triggered by a weakened, failed, or too old Ford’s vehicle battery. In every vehicle, the battery is a very important component of the electrical system.
Many people fail to take care of their car’s battery, which can cause other electrical components to be damaged when the battery is fully damaged.
2. Software Glitches
It is often the case that software glitches are caused by incomplete software updates, corrupted data, or programming errors. ECUs (electrical control units) fail or malfunction when software issues arise.
3. Electrical Problems
There is a possibility that the accessory system may remain on even if the circuits, electronic components, or wiring are damaged or loose. There are several problems that can arise as a result of electric issues, including the disruption of radios, windows, and lighting.
4. Ignition Issues
If you receive the full accessory power active message, it might be due to a faulty ignition switch or its components. Electrical accessories remain powered even when you remove your ignition key if your ignition switch doesn’t shut off your engine completely.
5. Issues with the electric control unit (ECU)
It could be an accessory power light if there’s a problem with the electrical control unit. In case of a defective ECU, improper signals are sent to the computer system, causing it to act in accordance with those signals.
Ford’s solutions for full accessory power
Here’s how you can prevent these types of electric issues in the future with the solutions to all of the causes.
1. Check the battery’s condition
Monitoring the battery’s condition is the first thing you should do. If the battery’s not fully charged, you should charge it first. Make sure both terminals are clean and take a lot of time. Having a weak or old Ford car battery can cause your trip to be disrupted and cause several problems.
You can also deplete the battery by listening to the radio or listening to music while the vehicle isn’t running, or using the navigation system for an extended period of time. A low battery charge will automatically shut off the accessory power after a certain time. Therefore, it is recommended to limit accessory power use if your battery is not sufficiently charged.
2. Updated Software
Routine maintenance should be performed on the software. Obtain a reprogramming from a certified technician if there are bugs. In addition, I suggest you use an error code or fault scanner to check the software.
3. Ignition switch replacement
All ignition switch components must be thoroughly inspected and ensured they are working correctly. Replacement of damaged ignition switches with new ones that are of high quality is recommended when they show signs of wear.
The electrical system should be turned off properly after you have changed the parts so that your battery will not be drained after the engine has been turned off.
4. Genuine parts should be used
Be sure to use genuine, high-quality parts that will last a long time and are compatible and durable. As well as improving engine performance, genuine parts keep the computer’s ECU updated with the relevant information.
5. Examine electrical systems
Wires that are damaged or cut should be repaired or replaced, loose connectors should be tightened, and the accessory systems should be supplied with suitable current. If you connect a charger, turn on the lights, and open the windows, you will be able to verify that the accessory components operate properly.
6. Scan tools for diagnosis
Getting the exact part that indicates the accessory power is best done with a diagnosis scan tool. An automated scan of the system is conducted by this tool, which identifies any errors. Every error is fixed individually by mechanics, and the overall vehicle stops malfunctioning.
