BCM failure refers to a Body Control Module malfunction. The inspection method involves connecting the ADC input port to the input of a comparator, with the comparator circuit's output linked to the MCU's interrupt capture IO port. If a rising edge interrupt is detected, it indicates a short circuit fault. Below is an introduction to BCM: 1. The Body Control Module, abbreviated as BCM, in automotive engineering refers to the Electronic Control Unit (ECU) used to control the vehicle's body electrical systems. It is one of the essential components of a car. 2. Common functions of the Body Control Module include controlling power windows, power mirrors, air conditioning, headlights, turn signals, anti-theft locking systems, central locking, and defrosting devices. The BCM can connect with other vehicle ECUs via a bus.

What Causes Engine Shaking the Day After Driving Through Water?

Engine shaking after driving through water occurs because a small amount of water enters the high-voltage wires and the engine air filter element when the vehicle is submerged. Reasons for vehicle shaking after water immersion: Engine shaking after driving through water happens because minor water ingress into the high-voltage wires and air filter element increases intake resistance and allows water to enter the combustion chamber. This leads to poor ignition system performance, and in severe cases, spark plugs may fail to ignite, potentially causing the engine to stall. Additionally, engine shaking could result from driving through excessively deep water, where submerged exhaust outlets affect proper exhaust flow. Proper procedure when driving through water: When approaching water, downshift to 1st or 2nd gear in advance and maintain full throttle to power through. If water submerges the exhaust pipe causing significant power loss (where acceleration becomes ineffective), maintain full throttle without shifting gears mid-crossing. After crossing, stop in neutral gear. Rev the engine several times to expel water from the exhaust system. Before resuming driving, pump the brakes several times and only continue when braking functions normally.
