Regal's body human-machine module is a unit attached to the fuse box. There is one below the left front pillar, and another fuse box below the right front pillar, which also contains a body control module. Body Control Module: The body controller includes a power supply connected to various circuits, with the main controller connected to the execution circuits of input signals. It is characterized in that the input end of the main controller is connected to the output end of the airbag controller. The airbag controller outputs a low-level pulse signal when the vehicle rolls over or collides. Due to this structure, the input end of the main controller is connected to the output end of the airbag controller. Body Control Module Functions: Power management, lighting control, wiper control, central door locking, remote control reception, vehicle anti-theft, engine anti-theft control, and self-diagnosis in fault mode.

From my experience with the new Buick Regal, the location of the human-machine module is quite crucial. This thing is essentially the main control unit for the car's screen and audio system. In the new Regal, it's usually hidden behind the panel on the driver's side under the dashboard. I've tried to dismantle it myself—you need to open the glove box or the cover under the center console to access it. The design is quite discreet to avoid interfering with driving, but if you need to inspect or replace it, be careful not to short-circuit the wiring. Normally, don’t tamper with the module while driving to avoid affecting safety features like navigation or air conditioning. I remember last time when my screen malfunctioned and displayed distorted images, I immediately took it to the shop. The mechanic found that the module’s wiring was loose. The repair cost wasn’t high—just a few hundred bucks. During regular maintenance, it’s good to quickly check the related wiring.

Over the years of car enthusiasm, I've become quite familiar with the new Regal. Locating its human-machine interface module isn't difficult—it's usually tucked away in that small space behind the center console. You can spot it by removing either the audio panel or the storage compartment on the passenger side. But don't rush into DIY; there are numerous wires inside, and mistakes could blow fuses or trigger alarms. If the module lags, it affects music and Bluetooth connectivity. I've encountered slow response several times, which turned out to be due to poor ventilation and accumulated dust. Simply clearing the cooling vents fixed it. Positioned near air vents, it's prone to overheating in summer heat; adding some heat-resistant padding can extend its lifespan. Before tinkering, check the manual or search for online videos to learn safe procedures—the safest bet is leaving it to professional mechanics.

For friends driving the new Regal who ask about the location of the human-machine module, it's important to remind them to be cautious. This component controls the display screen and function buttons, and is usually fixed in a hidden area at the bottom of the dashboard, making it difficult to access directly. Avoid attempting to disassemble it yourself, as plastic clips or stripped screws can be hard to repair. If the module malfunctions, such as rebooting or freezing, it may affect the reversing camera, posing a driving risk. My suggestion is to first disconnect the power for a while and then restart to test. If the issue persists, drive to the 4S store for inspection as soon as possible. During regular maintenance, they can quickly locate and clean the dust around the module, extending its lifespan.

The human-machine module in the new Regal is essentially the core of the vehicle's infotainment system, mostly installed under the dashboard in front of the driver's seat and integrated into the central control system. Its location is easy to find, but tools are required to remove the panel. If issues arise, such as unresponsive touchscreens or intermittent sound, first check the fuses and connection cables. Avoid placing clutter in that area during daily use to prevent obstructing heat dissipation. Don't panic if a malfunction occurs—minor issues can often be resolved by restarting the ignition, while more serious problems should be checked by a technician using a diagnostic tool for accuracy. Repairs are generally affordable, typically costing around two to three hundred yuan.
