What do the ACC-ON indicators on the vehicle ignition switch represent?
2 Answers
Vehicle ignition switch indicators ACC-ON represent the following: When the key is in the ACC position, some of the vehicle's electrical equipment is powered, such as the radio and audio system, while other components remain unpowered. When the key is in the ON position, all components of the vehicle are powered, including the engine system. The four positions of the ignition switch represent the following: LOCK position: This is the position where the key is inserted or removed. At this position, the vehicle's circuits are completely shut off except for the anti-theft system and interior lights, and the steering wheel is locked. ACC position: Accessory power position. When the key is turned to this position, the accessory circuits are activated, allowing devices such as the radio to function. ON position: Power-on position. When the key is turned to this position, all the vehicle's circuits are activated, and the system performs necessary preparations and self-checks for starting the engine. The key remains in this position during normal driving. START position: Starting position. When the key is turned to this position, the starter circuit is activated, causing the engine to crank and start. Upon release, the key automatically returns to the ON position.
I usually pay attention to these small details when driving. The ACC position is the first notch when you turn the key. At this point, you can use the radio, cigarette lighter charger, etc., but the engine isn't started. Last time I waited for someone, I turned it to this position to listen to music, but be careful not to exceed half an hour, or the battery might drain. The ON position is the second notch when turning the key. All dashboard lights come on, the steering wheel lock is released, and air comes out of the vents, but the engine isn't started yet. The difference between these two positions is quite important, especially in winter. Some people prefer to turn to the ON position and wait a few seconds to let the fuel pump work before starting, which is better for the engine. Older cars are gradually being replaced by push-button starts, but traditional key ignitions still feel more reassuring.
