The power steering system of a car is roughly divided into two categories: hydraulic and electric. The assisting principle of the Electro-Hydraulic Power Steering (EHPS) system is the same as that of the traditional mechanical hydraulic power steering system, using the power generated by the electric motor to assist the driver in steering. Here is a related introduction to the power steering system: 1. The Electro-Hydraulic Power Steering (EHPS) system adds the function of an electric steering pump, with the start and stop of the electric pump controlled by the ECU. When no steering action is performed, the electric steering pump is turned off, unlike the mechanical hydraulic power steering pump, which is always connected to the engine via a belt. 2. The Electric Power Steering (EPS) system consists of a torque sensor, a control unit (ECU), an assist motor, and a mechanical steering gear.

How Often Should a Vehicle's Radiator Be Cleaned?

Regarding the cleaning cycle for the interior of the radiator, it is recommended to clean the car's radiator cooling system twice a year—once in the first half of the year and once in the second half. This maximizes the lifespan of the car's radiator. It is best to perform the cleaning alongside the replacement of the antifreeze (antifreeze should be replaced every 2 years or 40,000 kilometers). Below is a related introduction to the cleaning method: 1. Ensure the engine is cooled down and turned off. Remove the radiator cap, making sure the engine is cool. If the radiator cap is too hot to touch, it indicates the engine hasn't cooled down yet; 2. Open the drain plug at the bottom of the radiator to let the coolant flow into a bucket. The coolant should be disposed of properly to avoid environmental harm; 3. Close the drain plug and fill the radiator with water; 4. Start the engine, turn on the heater control system (this will open the heater control valve), add the cooling system cleaner, and let the engine idle for 30 minutes (or follow the instructions on the cleaner bottle); 5. Turn off the engine and let it cool for 5 minutes. Drain the liquid from the radiator; 6. Close the drain plug, fill the radiator with water, and let the engine idle for 5 minutes. Then refill with a 50/50 mix of water and ethylene glycol antifreeze/coolant (use the same type of coolant previously used in the car).

What are the reasons for the Passat B5 shaking during startup?

Passat B5 shaking during startup is mainly caused by the ignition system, unstable oil pressure, and engine aging. Solutions for the ignition system: Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can also lead to such faults. Solutions for oil pressure: If you have already cleaned the engine carbon deposits, washed the throttle body, replaced the oil pads and spark plugs, but still notice body shaking at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump supply pressure or incorrect values and poor performance of the intake pressure sensor can cause body shaking. Solutions for aging engine components: Car shaking is also related to aging engine mounts. Engine mounts are actually the shock absorption system of the engine, responsible for absorbing minor vibrations during engine operation. If the engine mounts are faulty, these vibrations will be transmitted to the steering wheel and the interior, causing shaking at idle.

How to fix the rear wheel lock-up on Lechi?

First, drive forward and then backward three times, making sure not to move too much, otherwise the brake pads and brake drum won't separate. Pour 100°C boiling water between the brake pads and brake drum; the thermal expansion might cause them to separate automatically. Tap both sides lightly, which might help separate them; if that doesn't work, try kicking the tire a few times—it might loosen up.

How to Operate an Automatic Transmission on a Long Downhill Slope?

Correct method for long downhill slopes with automatic transmission: When encountering a long downhill slope, simply shift the gear to D (Drive) mode, then control the vehicle's speed by managing the throttle. At high speeds, the engine itself generates a braking force. Therefore, releasing the throttle will utilize this engine braking effect to slow down the vehicle, allowing you to control speed using the principle of engine braking during descent. Below are precautions to note when driving an automatic transmission car: 1. Unless specifically required, avoid frequently shifting the gear lever between D, 3, 2, and 1 modes. Particularly, never shift into N (Neutral) while driving or coast downhill in N mode. Doing so may reduce oil supply from the transmission pump due to the engine idling, potentially causing damage to transmission components from inadequate lubrication. 2. When starting an automatic transmission vehicle, always ensure the gear is in P (Park) or N mode. Otherwise, it may damage the transmission. 3. If the automatic transmission vehicle fails to start, do not attempt to push-start or tow it with another vehicle, as this can cause severe damage. Always seek professional towing services and specialized towing vehicles. 4. When reversing an automatic transmission vehicle, make sure the car is completely stopped before shifting into R (Reverse) mode. Otherwise, it may also damage the transmission.

How is overloading a family car by one person penalized?

Overloading a private car by one person results in a 2-point deduction and a fine. Overloading a passenger vehicle by one person leads to a 6-point deduction. Generally, exceeding 50% capacity incurs a fine and license suspension. The primary legal basis is the "Scoring Standards for Road Traffic Safety Violations," which stipulates that driving an operational passenger vehicle or school bus with passengers exceeding the approved capacity by less than 20%

Where is the body control module located in the Jeep Renegade?

The body control module of the Jeep Renegade is located on the left side of the steering column under the left side of the instrument panel, beneath a plastic cover. Logic mode management function: The BCM has a logic mode management function. When activated, some electrical loads can be turned off. The logic mode can be deactivated through the diagnostic equipment by selecting the "Command" item in the BCM's "Other Functions" menu. Alternatively, this function can also be deactivated through a manual procedure. Diagnostic function: The BCM's diagnostic function is located in the "Other Functions" menu of the BCM. When the ignition switch is turned to the "ON" position, the BCM performs a vehicle configuration check using the PROXY file. The BCM sends a PROXY configuration code to all PROXY-configured modules on the network. The PROXY-configured modules will then send their own configuration codes, which the BCM compares. If a code mismatch is found, the BCM will set a fault code. If the fault code persists for 3 ignition cycles, the BCM will send a signal to the instrument cluster to make the odometer flash.
