What Causes Abnormal Noise When Braking Hard?

Can You Continue Driving When the ABS Light Is On?

ABS fault light is on, it is recommended not to continue driving, because the ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to slow down or adjust the vehicle's trajectory, which poses significant safety risks. There are various states when the ABS light is on, with different causes and solutions for each state, as detailed below: State 1: ABS fault light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed and the wheel's slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Check the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently turns on, but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS light turns off. The ABS system's power supply voltage is too low, possibly due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start until the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer malfunction. Solution: Loosen the grounding screw on the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light turns on during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant difference between the rear and front wheel speeds; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently turns on. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary.

What is the function of valves?

Valves are specifically responsible for introducing air into the engine and expelling exhaust gases after combustion. Here are the relevant details: Types of valves: Engine valves are divided into intake valves and exhaust valves. The intake valve's function is to draw air into the engine to mix with fuel for combustion; the exhaust valve's role is to expel the burned exhaust gases and dissipate heat. Composition and performance of valves: A valve consists of a valve head and stem. The valve head operates at very high temperatures and endures gas pressure, valve spring forces, and inertial forces from transmission components. With poor lubrication and cooling conditions, valves must possess certain strength, stiffness, heat resistance, and wear resistance.

How to Troubleshoot a Lit Engine Warning Light?

Methods to troubleshoot a lit engine warning light: 1. Disconnect the positive or negative terminal of the car battery; 2. Reconnect it after a few seconds. Reasons for a lit engine warning light: 1. Sensor issues; 2. Poor engine maintenance; 3. Substandard fuel quality; 4. Poor combustion of the air-fuel mixture; 5. Dirty car air filter; 6. Damaged catalytic converter or thermostat; 7. Engine misfire. An engine is a machine that converts other forms of energy into mechanical energy, determining the car's power, fuel efficiency, stability, and environmental performance. Car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.

Where is the emergency trunk release switch located on the Ford Edge?

Ford Edge's emergency trunk release switch is located at the trunk latch, concealed under a rectangular cover panel that needs to be pried open. Below are detailed instructions about the emergency trunk release: Usage method: In emergency situations, after accessing the trunk through the rear seats, use a key or screwdriver to pry open the cover panel, then rotate the switch to open the trunk from inside. Other types of trunk release switches: Common variants include pull-cord/ring type, covered type, and concealed type. Operation difficulty ranges from easy to difficult, with concealed types being the most aesthetically pleasing but requiring tools for operation as they cannot be activated manually.

Why is the Lincoln MKZ relatively inexpensive?

Lincoln MKZ is relatively inexpensive due to its average brand influence and the shorter wheelbase of this model. Here are the detailed reasons: Average brand influence: Lincoln entered the Chinese market in the 1980s but withdrew in 2008 due to poor sales, only to return in 2014. During its absence, brands like Cadillac, Lexus, Jaguar, and Land Rover quickly captured Lincoln's former market share, significantly diminishing Lincoln's brand influence. Shorter wheelbase: The Lincoln MKZ measures 4925/1864/1477mm, the largest in its class, but its wheelbase is only 2850mm, which does not align with consumer preferences.
