Accessory mode” in a Honda refers to a mode in the vehicle’s ignition system that allows you to use certain electrical components without starting the engine.
When you turn the key or press the start button to the “Accessory” position, the car’s electrical system powers up, enabling you to use features like the radio, power windows, power outlets, and other accessories without actually starting the engine.
One issue that many Honda owners may face is being stuck in accessory mode, leaving them unable to start the car or turn it off. If you’re experiencing this problem, don’t panic!
So, how do I get my Honda out of accessory mode? Read on to find out all about Honda accessory mode.
Why Is My Honda Stuck In Accessory Mode?
If your Honda is stuck in accessory mode, it may be for a few different reasons. Here are a few things you can try to diagnose the problem:
1. Dead Battery
The most common cause of a stuck accessory mode is a dead battery. If the battery is not providing enough power to start the engine, the car may be stuck in accessory mode. Try jumpstarting the battery or replacing it if it is old or damaged.
2. Ignition Switch
The ignition switch sends power to the starter and the accessories. If the switch is faulty, it may be stuck in accessory mode. You may need to replace the ignition switch.
3. Key Cylinder
The key cylinder is the ignition switch part where you insert the key. If the cylinder is damaged or worn, it may not be able to turn to the “on” position, leaving the car stuck in accessory mode. You may need to replace the key cylinder.
4. Shift Interlock
Some Honda models have a shift interlock that prevents the car from being shifted out of the park if the key is not in the “on” position.
If the shift interlock is faulty, it may prevent the car from leaving accessory mode. You may need to have the shift interlock repaired or replaced.
What Happens When Your Honda Gets Stuck In Accessory Mode?
Reports are coming in that some vehicles are stuck in ACCESSORY mode and are unable to shut down fully.
The audio unit stays on, the ENGINE START/STOP button blinks, the gear position indicator doesn’t show P, and the doors won’t lock. We have found that an incorrectly adjusted shift cable causes the problem.
This issue can be resolved by adjusting the cable per the service information. That should work. Continue troubleshooting your system as normal if it doesn’t.
What To Do With The Key That Got Stuck In Accessory Position?
Once the key has been inserted into the ignition switch, it should not be able to come out after turning the key.
The lock inside the tumbler has failed when the key can be removed from the ignition switch in either the On or Accessory position.
If you are experiencing issues with the steering wheel lock, try turning the steering wheel side to side. A new ignition switch tumbler and a new key will be needed if the steering wheel lock is not the problem.
The graphite in the tumbler can be put into the ignition switch if the key is stuck in the accessory position and will not shut off the engine; however, it will damage the tumbler, but you can shut off the engine.
To resolve your stuck-in-accessory position problem, I recommend replacing the ignition switch and key.
You should contact a technician if you need assistance shutting off the ignition switch on your vehicle.
How Does Honda’s Accessory Mode Work?
To enter accessory mode, you don’t need to step on the brake pedal and press the start button. It’s as simple as that.
There are some cars with two accessory modes: one for low-power items like radios and one for higher-power items like fan motors and window motors.
When you enter the vehicle and press the start stop button without pressing the brakes pedal, the vehicle goes into accessory mode, allowing the audio system and accessories to be activated.
Once all electrical components are active, press the start stop button again.
How to Avoid Getting Stuck in Accessory Mode
To prevent your Honda from getting stuck in accessory mode, follow these tips:
1. Regular Maintenance
It is crucial to catch any potential problems early. Having your car serviced regularly and having the ignition system, battery, and wiring checked by a professional can prevent many problems.
2. Make Sure Your Software Is Up-To-Date
In case your Honda has an infotainment system, you should keep its software updated. By doing this, any bugs that may cause your car to get stuck in accessory mode can be prevented.
3. Maintaining A Healthy Battery
You should regularly check the battery in your car and the battery in your key fob. Your car may be in need of a battery replacement if you notice any issues, such as difficulty starting your car.
In addition to preventing your car from getting stuck in accessory mode, taking good care of it prolongs its lifespan and makes driving smoother and safer.
My years as a mechanic have taught me the importance of regular maintenance.
How Do I Get My Honda Out Of Accessory Mode?
The ENGINE START/STOP button is used to cycle through power modes or start the engine.
You can switch between the Accessory and On modes by pressing ENGINE START/STOP once without pressing the brake pedal.
For On mode, press it again. You can start your engine by pressing and holding the brake pedal, then pressing the ENGINE START/STOP button.
Does Accessory Mode Drain Car Battery?
By turning the key to the “accessory” position, nothing is actually drawn from the battery. Certain accessories, such as the radio, the power windows, and the interior lights, require a limited amount of electricity to run.
Can I Leave My Car On Accessory Mode?
With a few lights on, you can easily leave it on for hours, but not for days if you turn off all the lights and accessories.
If you cannot diagnose and fix the problem yourself, it’s best to take your Honda to a certified mechanic or dealership for further diagnosis and repair.
