What is the reason for the Subaru central lock not responding?

Subaru central lock cannot be opened due to poor contact points or wiring issues in the central lock system. Poor Contact: There may be oil stains, debris, or foreign objects on the contacts; prolonged use may cause surface oxidation; arc erosion can lead to defects, burrs, or the formation of metal particles; or there may be jamming in the moving parts. Solutions include: For oil stains, debris, or foreign objects on the contacts, wiping with a cotton cloth soaked in alcohol or gasoline can help. If the contacts are made of silver or silver-based alloys, the formation of an oxide layer or minor burns and blackening due to arcing generally does not affect functionality and can be cleaned with alcohol, gasoline, or carbon tetrachloride solution. Wiring Issues: Poor contact at the connection points between the busbar and other equipment can interrupt circuit operation. A fault in a section of a circuit during electrical equipment operation can cause a line break, blocking current flow and leading to abnormal conditions in related components of the electromechanical equipment. Any wiring issue can have a certain impact on the entire electromechanical working system. Solutions: If using the remote to unlock the door, the remote battery may be dead, or there may be strong signal interference nearby. The remote key usually contains a hidden mechanical key, which can be used instead. If the mechanical key cannot open the car door, the central lock system may be in an electronic lock state, or the door lock cylinder may be stuck due to prolonged use and cannot be turned. The first situation requires waiting one or two hours for the lock to release before attempting to unlock again. The second situation may require forceful measures, such as breaking the window to open the door, or contacting a 4S shop for repairs.

What Causes the Fault Light to Illuminate in a Haval H6?

The reasons for the fault light illuminating in a Haval H6 include poor-quality or substandard gasoline, oxygen sensor malfunction, excessive spark plug carbon buildup, and engine knocking. Regardless of the cause triggering the engine fault light, it is necessary to use a computer diagnostic tool for diagnosis. If it is a false fault code, simply clear it. If there is a genuine fault, troubleshooting and repairs should be conducted based on the fault code, such as cleaning spark plug carbon deposits, replacing the oxygen sensor, or changing the gasoline. Often, shortly after refueling, the engine fault light on the car's dashboard illuminates. This is usually due to filling up with poor-quality gasoline at non-standard gas stations, leading to incomplete combustion of the air-fuel mixture during engine operation and triggering the fault light. While this does not affect driving safety, it can cause some degree of harm to the engine. The front oxygen sensor's role is to detect the air-fuel ratio under different engine operating conditions, with the ECU computer using this signal to adjust fuel injection and calculate ignition timing. If the oxygen sensor is damaged or its connector is damaged or loose, it can cause the air-fuel mixture to become too lean or too rich, leading to the fault light illuminating. Spark plug carbon buildup can result in poor engine performance, manifesting as difficulty starting, unstable idling, poor acceleration, backfiring during rapid acceleration, excessive exhaust emissions, and increased fuel consumption. Engine knocking can cause the car to lack power during driving, produce excessive engine noise, and in severe cases, be accompanied by a knocking sound from the cylinders.

What is the difference between dealership invoice and auto trade invoice?

Dealership invoice refers to the purchase invoice from a 4S store, while auto trade invoice refers to the purchase invoice from an auto trade company. The differences between the two lie in the after-sales service and price of the vehicle. Generally, buying a car from a 4S store is more expensive than from an auto trade company. This is because auto trade companies source vehicles from 4S stores with the lowest prices nationwide, whereas 4S stores source directly from manufacturers. Additionally, the operational costs of 4S stores are higher than those of auto trade companies, resulting in different prices on the invoices. Using an auto trade invoice might affect the vehicle's future after-sales service. Some vehicles purchased from auto trade companies may only receive after-sales service at local 4S stores, which may not be recognized by 4S stores in other regions. However, with a 4S store invoice, after-sales service can be obtained at any 4S store nationwide. How to distinguish between a genuine auto trade invoice and a 4S store invoice: Check the watermark: Genuine invoices are printed on special anti-counterfeiting paper with black and white watermarks, and the watermark pattern has a noticeable texture when touched. Fake watermarks have a weaker texture and appear blurry. Prize area difference: The covering layer in the prize area of a genuine invoice is made of laser gold-stamped film, presenting a matte finish, while most fake invoices have inferior covering layer technology in the prize area. Color difference: Genuine invoices have a deeper color, appearing pinkish, while fake invoices have a much lighter color, looking somewhat pale.

What are the symptoms of overfilling AT transmission fluid?

Overfilling transmission fluid can cause gear shift shocks, automatic transmission fluid leakage, and reduce the cooling function and transmission efficiency of the gearbox. Automatic transmission fluid leakage: If the transmission fluid level is too high, the rotating components will come into contact with the fluid during driving. Under the agitation of high-speed rotating components such as planetary gear mechanisms or clutches, the fluid will expand and boil, causing it to spurt out from the filler hole and vent valve. Since the transmission is located right above the exhaust pipe, fluid dripping onto the exhaust pipe during driving will result in black smoke emerging from the car's skirt, making it appear as if the car is on fire. Reduced cooling function and transmission efficiency: The main functions of transmission fluid are lubrication and cooling. The fluid transfers heat through the transmission housing and transmission cooler. If too much fluid is added, the rotation of gears will encounter greater resistance, reducing the cooling function and transmission efficiency. This requires the engine to consume more fuel, decreasing the vehicle's overall fuel economy. Moreover, this energy loss will be converted into heat inside the transmission, causing the transmission temperature to continuously rise. Ultimately, this leads to premature wear of the bearings and burning of the friction plates inside the transmission. Both replacement and repair are costly. In summary, the fluid level should neither be too high nor too low. During the design phase of the transmission, lubrication and temperature rise tests are conducted, and the fluid level is precisely verified.
