Does the Nissan X-Trail's brake light go through the control module?

Nissan X-Trail's brake light goes through the control module. The brake light serves to alert vehicles behind that the front car has braked, prompting them to slow down and avoid rear-end collisions. Taking the 2021 Nissan X-Trail as an example, it belongs to the compact SUV category with the following dimensions: length 4675mm, width 1820mm, height 1722mm, wheelbase 2706mm, fuel tank capacity 65l, and curb weight 1514kg. The 2021 Nissan X-Trail features a MacPherson strut independent front suspension and a multi-link independent rear suspension. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 151PS, maximum power of 111kW, and maximum torque of 194Nm, paired with a 7-speed continuously variable transmission.
The brake lights of the Nissan X-Trail are typically controlled by the body control module. When braking, the switch signal is first transmitted to the module, which then activates the lights. This design enhances system intelligence, enabling it to detect issues like burnt-out bulbs or wiring faults and automatically generate error codes. If the module malfunctions—due to loose connectors or internal damage, for example—the brake lights may fail to illuminate, requiring diagnostic tools for troubleshooting and repair. From my experience, regular inspection of electrical connections is crucial to prevent failures caused by moisture or vibration. Modern vehicle designs prioritize this approach for reliability and safety. Avoid opting for non-OEM modules to prevent system conflicts. Timely maintenance ensures brake lights remain functional, as their failure on highways can lead to severe accidents.
The brake lights on my X-Trail are indeed controlled by a module. I remember last time on a business trip, the lights suddenly went out, which was quite a scare. At the repair shop, they found the relay in the module had poor contact. The worker took it out, cleaned it, and it worked fine again, costing very little. When driving, pay attention to the light's response after pressing the brake. If there's a delay in lighting up or it doesn't light at all, it's mostly a module or switch issue. Preventive measures are simple: avoid modifying the circuit and keep the battery voltage stable, which helps the module work more durably. Some car owners think the module is unnecessary, but it actually integrates multiple functions, making the whole system more efficient. Regular maintenance is key; technicians will use equipment to check the module's condition, reducing unexpected issues.
