ix35 body BCM control module is integrated with the engine computer and located under the dashboard. The relevant information about the Body Control Module (BCM) is as follows: Introduction: It is a powerful control module designed to achieve discrete control functions and control numerous electrical appliances. The functions of the Body Control Module include: electric window control, central door lock control, remote anti-theft, lighting system control, electric mirror heating control, instrument backlight adjustment, power distribution, etc. Coordination function: The Body Control Module (BCM) coordinates different functions inside the vehicle through signals. It manages numerous vehicle functions, including door locks, alarm sound control, interior and exterior lighting, safety functions, wipers, turn indicators, and power management. The BCM, which is bound to the vehicle's electronic architecture, provides maximum reliability and cost-effectiveness while reducing the number of required plug connections and cable harnesses.
I think when locating the BCM control module in the ix35 model, based on my practical experience as someone who frequently helps others with car repairs, it is generally installed in the area below the driver-side dashboard, near the steering column or above the foot pedals. You need to crouch down and carefully inspect or gently remove the decorative panel near the foot pedals to spot a small black box connected to wiring harnesses—that's the BCM, responsible for handling body electronics like door locks and windows. I recommend disconnecting the vehicle's negative battery terminal before searching to avoid short circuits, and also consulting the owner's repair manual as the exact position may vary slightly by model year. Although its location is fixed, the design facilitates maintenance. Those with strong hands-on skills can locate it themselves, but if you're unfamiliar with electronic circuits, it's safer to consult a professional technician.
I've encountered similar issues with my own ix35, such as the central control malfunctioning, so I went to explore the BCM location. Typically, it's located in front of the driver's seat, in the space under the steering wheel, sometimes hidden beside the foot pedal or inside the door frame. After checking a few times, I found that removing a few plastic trim panels allows direct access to the module itself. This placement is designed to protect against dust and water while facilitating maintenance. If you really can't find it, trying to trace the wiring from the fuse box is a good method. Remember to disconnect the battery to ensure safety and avoid injuring yourself. Practical experience tells me the location isn't too complicated—even beginners can attempt it, but patience is required.
