Where is the Vios fog light relay located?

Vios fog light relay is located inside the fuse box in the engine compartment. The relay, also known as an electrical relay, is an electronic control device that consists of a control system and a controlled system. It is commonly used in automatic control circuits, essentially functioning as an automatic switch that uses a smaller current to control a larger one. The Vios is an entry-level family car specifically designed and developed by Toyota for the Asian market. Based on the NBC platform with an extended wheelbase, the Vios developed on this compact car platform nearly reaches the level of a compact sedan. The dimensions of this car are 4420mm in length, 1700mm in width, 1490mm in height, with a wheelbase of 2550mm.

Where is the exhaust brake on the HOWO truck?

HOWO truck's exhaust brake is located to the left of the clutch pedal, which is the engine shutdown switch. When pressed while driving, it activates the exhaust brake. The exhaust brake is implemented within the engine, commonly by closing the engine's exhaust passage. This causes the engine pistons to encounter gas backpressure during the exhaust stroke, thereby resisting engine operation and creating a braking effect to control vehicle speed. HOWO is a domestically advanced, high-end new-generation heavy-duty truck independently developed by China National Heavy Duty Truck Group Co., Ltd. It incorporates key advanced global heavy truck technologies, targets both Chinese and international regional markets, aligns with international technical standards, and possesses independent brand and intellectual property rights.

What is the normal value of fuel injection pulse width?

The normal value of fuel injection pulse width is between 1.5ms and 2.9ms. The unit of fuel injection pulse width is milliseconds (ms). A larger displayed parameter value indicates that the fuel injector remains open longer each time it sprays fuel, resulting in a richer air-fuel mixture for the engine. Conversely, a smaller displayed parameter value means the fuel injector opens for a shorter duration each time, leading to a leaner air-fuel mixture for the engine. Fuel injection pulse width refers to the duration of each fuel injection controlled by the engine's ECU, which is the most critical indicator of whether the fuel injector is functioning properly. Since the fuel pressure in the engine's fuel system is constant, the fuel flow rate during injection is also constant. Therefore, the amount of fuel injected can only be controlled by the duration of the injection. As electronic fuel injectors in EFI engines are controlled by solenoid valves and the engine operates at high speeds, the injection time is extremely brief. Consequently, the ECU sends a very short pulse signal for fuel injection, and the time width of this signal is the fuel injection pulse width.

Should I engage the parking brake when shifting to P in an automatic transmission?

You should engage the parking brake when shifting to P in an automatic transmission; otherwise, it may damage the locking mechanism of the P gear. Automatic transmission vehicles are equipped with a P gear, which is the parking gear used when stopping and turning off the engine. If you do not shift into P gear before stopping and turning off the engine, the car cannot be turned off normally. Automatic transmission vehicles also have an N gear, which is the neutral gear. When shifted into N gear, the connection between the transmission and the wheels is disconnected, meaning the engine's power cannot be transmitted to the wheels, so the car cannot move normally in N gear. When in N gear, there is no locking mechanism to secure the transmission gears, so the car can move if the parking brake is not engaged.

What does it mean when the car EPS light is on?

When the car EPS light is on, it indicates a fault in the electric power steering system. If accompanied by abnormal conditions such as heavy steering wheel turning, steering noise, steering wheel shaking, or poor steering wheel return ability, it is not advisable to continue driving. If none of the above-mentioned abnormal conditions occur, you can safely stop the car and restart the engine to resolve the issue. The EPS is a power steering system that relies on electric assistance to provide auxiliary torque, and its function is to assist the driver in steering operations. Based on the steering torque signal from the steering wheel and the vehicle speed signal, the electronic control unit adjusts the motor to generate an appropriate amount and direction of auxiliary force.

Can Heated Rearview Mirrors Be Installed Aftermarket?

Heated rearview mirrors can indeed be installed aftermarket. The principle behind heated mirrors is quite simple: it involves installing electric heating elements inside the mirror lenses on both sides and addressing wiring methods. However, it is recommended that vehicle owners refrain from attempting this modification themselves, as it may affect the original vehicle circuitry and pose certain safety hazards. It is advisable to entrust this task to professionals. Automotive rearview mirrors are located on both sides of the vehicle's front and inside the cabin. These mirrors reflect conditions behind, beside, and below the vehicle, allowing drivers to indirectly observe these areas, significantly expanding their field of vision.
