It is strongly advised not to start the car if the BCM is broken. Here are the relevant details: 1. BCM: BCM stands for Body Control Module. The primary function of the body controller is to coordinate the operation of various functional components of the vehicle through electrical signals. The body controller can manage electronic components such as windows, airbags, turn signals, and wipers. Almost all modern vehicles are equipped with a body controller, which enables increasingly complex functionalities in today's automobiles. With advancements in computer systems and chip processing capabilities, body control systems are gradually evolving towards intelligent development. 2. Symptoms of a faulty car BCM: If the BCM is damaged, electrical components such as the sunroof, door locks, lights, wipers, voltage regulator, and multimedia system may fail to operate normally. For automatic transmission models, there might also be issues like the P-gear locking up, significantly affecting gear shifting. Additionally, if the BCM is not completely damaged, it could lead to problems like abnormal horn operation, erratic wiper function, starting failures, malfunctioning automatic door locks while driving, and central locking system failures. When the BCM is faulty, it should be repaired promptly.

What are the causes of chassis noise in the Mercedes-Benz GL350?

Chassis noise in the Mercedes-Benz GL350 may be caused by universal joint failure in the driveshaft, noise in the braking system, wheel bearing noise, clutch noise, and other reasons. Below are the specific details: Universal Joint Failure in the Driveshaft: Due to damaged dust covers and oil leakage not being repaired in time, the small bearings wear abnormally. Braking System Noise: Loose brake pads or calipers; noise caused by faulty brake pads or brake discs. Wheel Bearing Noise: Due to abnormal wear or burning of the bearings, a "humming" sound may occur at certain speeds, and this sound increases as the speed rises. Clutch Noise: The clutch release bearing lacks lubrication and has abnormal wear, so when the clutch pedal is pressed, noise occurs, and the noise disappears when the pedal is released.

What material is the side skirt of the new LaCrosse?

The material of the new LaCrosse's side skirt is steel plate. Car side skirt: It refers to the skirt panels installed on both sides of the vehicle body. When the car is driving at high speed, it can reduce air resistance, and its function is equivalent to that of an air dam, used to reduce the airflow entering the underside of the car from both sides, providing a certain aerodynamic effect. Under certain conditions, it can significantly reduce air resistance. Car side skirt materials: Generally, they can be divided into three types: steel plate integrated stamping, engineering plastic, and aluminum alloy integrated stamping. Among them, steel plate integrated stamping and aluminum alloy integrated stamping cannot be disassembled separately and require sheet metal cutting because they are integrated with the car body shell. On the other hand, engineering plastic materials can be disassembled separately, mainly connected to the car body through threads and clips, which is a detachable connection. The specific material depends on the car model.
