Where is the control box of the Premacy located?
3 Answers
The control box of the Premacy is located behind the fuse box. Function of the control box: The control box is used to centrally control external equipment in the compartment, and it works in conjunction with the set-top box to achieve centralized control of external devices such as amplifiers and call lights through the song selection interface. Control system: The car's central control manages comfort and entertainment devices such as air conditioning and audio systems. The central control includes the central door lock system, allowing the driver to control the opening and closing of all doors and the window lift system. The central door lock system primarily features central control, speed control, and individual control functions. The driver can control all door locks, and the doors automatically lock when the vehicle reaches a certain speed.
I've worked in an auto repair shop for over a decade and often receive inquiries from Premacy owners about the location of the central control box. Typically, it refers to the body control module, which is standardly positioned beneath the dashboard near the passenger seat side. Sometimes it's hidden behind the glove compartment and requires removing a cover to access. If it's the engine control unit you're after, you'll find it in the engine bay next to the battery. When inspecting it yourself, exercise caution: disconnect the battery's negative terminal to prevent short circuits, and use a small flashlight to locate the plastic box mounted on a bracket. Note that its position may vary by model year—older versions might place it under the seat rails, while newer models integrate it deeper into the center console. If you can't locate it, don't worry—visit a dealership and have a technician point it out for you. Routine maintenance should include checking this area to prevent water damage or wiring issues from modifications, as early detection can avert major problems.
I've been driving my Premacy for five years, and the central control box is quite noticeable under the passenger seat. Just crouch down and lift the edge of the carpet to find a small plastic box. Remember, it was a bit dark when I first looked for it, so bringing a phone light helps. Don't worry, it's not complicated—it just controls the door locks and lights. If the location isn't obvious, check the manual or take a photo and ask the guys at the 4S shop; they know it well. When driving daily, be careful not to spill drinks or let small toys get stuck in it. Keep it dry for safe driving, and during regular car washes, simply wipe around the control box to prevent dust buildup.
