What does Toyota ACCESSORY mean?

[LeMicah]

Toyota accessory refers to the ACC power supply of Toyota vehicles. Before the car is started, if there is an ACC position on the key, simply turning the key to this position can power some low-power devices such as the radio and cigarette lighter. Below are detailed introductions about Toyota: 1. Overview: Toyota Motor Corporation is a Japanese multinational automotive manufacturer listed on the Tokyo Stock Exchange (TYO), Nagoya Stock Exchange (NAG), New York Stock Exchange (NYSE), and London Stock Exchange (LSE). 2. Others: The founder is Kiichiro Toyoda (1894-1952), and the current president is Akio Toyoda (grandson of Kiichiro Toyoda). The headquarters are located in Toyota City, Aichi Prefecture, Japan, and Bunkyo, Tokyo.

Toyota ACCESSORY refers to the first position of the vehicle's ignition switch, or the pure electric power-on mode for some new energy models. In this state, the engine does not start, but some electrical appliances in the car can work. For example, if you want to listen to the radio or charge your phone while waiting in the car, you can rotate the key to the ACC position to get power, and you can also operate the electric windows. However, remember not to use this mode for a long time, otherwise it may easily drain the battery. Some newer models also use this mode to control ambient lighting and USB ports. Last time I took a break at a service area, I relied on the ACC position to charge for half an hour, and when I came back, I found that the dashboard showed a slight drop in battery voltage. So it's fine to use it for a short time, but it's better to start the engine if it exceeds half an hour.

Simply put, it's the state where the vehicle is powered on but not started. When turning the key, stopping at the first resistance point puts the car in ACC mode. At this time, the steering wheel lock is released, dashboard lights illuminate, and the AC blower and audio system can be turned on. However, high-power devices like headlights and cigarette lighters may not work. I most often use this mode to listen to music while queuing at gas stations - it's much more fuel-efficient than idling. But be aware that older car batteries won't last long, while newer vehicles with power management systems can sustain this state longer. Hybrid vehicles can also enter a similar state by pressing the start button twice while in P mode, where the engine doesn't engage but natural air ventilation remains available.

ACC mode is the vehicle preparation stage, similar to a computer's boot-up self-check. I usually turn the key to the ACC position first and wait for the airbag light to go off before starting the engine, allowing the system to complete its self-check. During this time, the central control screen can be used to set up navigation, and the power seats can also be adjusted. Some cars are designed intelligently, automatically charging the battery when the brake is pressed in ACC mode. However, it's important to note that the electronic parking brake may not release in ACC mode, especially when parked on a slope, so extra caution is needed. The most practical scenario is waiting in the car during rainy days; the ACC mode allows continuous operation of the wipers without consuming fuel.

This is actually Toyota's ignition preparation position. When the key is turned to this position, you'll hear the relay click, indicating the circuit is connected but fuel isn't supplied. Mechanical enthusiasts like me specifically test this: in ACC position, you can activate the reverse camera but not the reverse radar, as the radar requires higher voltage. Friends modifying audio systems are advised to connect wires in ACC position for testing to avoid short circuits burning fuses. For modern keyless start models, press the start button twice without braking to enter this mode, which is suitable for temporarily retrieving luggage or debugging onboard equipment.

Simply put, it's a semi-powered state. When teaching beginners, I often use a smartphone analogy: the ACC position is equivalent to a phone with its screen on but not unlocked. In this state, the dashboard lights up for fault self-check, and the multimedia system can play music from a USB drive. This mode is extremely practical in real driving scenarios. For example, in winter, you can first turn on ACC to preheat the seat heaters before starting the engine, making the warm-up process more efficient. However, I once encountered an old Crown whose battery drained after staying in ACC mode for half an hour, so now I always set a countdown reminder on my phone.
