Dongfeng Tianlong EECU is caused by circuit issues, which prevent the Vehicle Electronic Control Unit (VECU) from receiving signals from the Engine Electronic Control Unit (EECU). Below is an introduction to the EECU: Composition of the EECU: The EECU in vehicles consists of a microprocessor (CPU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), and large-scale integrated circuits for signal conditioning and driving. Function of the EECU: The main function of the EECU is to monitor signals from various sensors on the engine and information sent by the VECU via the CAN bus, enabling control over components such as the exhaust brake solenoid valve, electric fan, and fuel injector solenoid valve to ensure proper engine operation. The primary role of the EECU is to collect various signals and serve as the computer that controls normal engine operation.

Is a Car from the Same Province Considered an Out-of-Town Vehicle?

Purchasing a vehicle from a different city within the same province is considered an out-of-town purchase. Precautions for Out-of-Town Car Purchases: Temporary License Plate: Avoid purchasing on weekends, as most vehicle management offices are closed and cannot issue temporary plates promptly. Without a temporary plate, you cannot drive the car back to your city. Emission Standards: Emission standards vary by city. For example, Guangzhou enforces the China V standard. Buying a China IV standard car to save money may prevent registration in your city. Financing: Generally, out-of-town 4S dealerships do not offer financing options; full payment is required. If financing is necessary, consider using e-commerce platforms, where down payments and interest rates are now more accessible. Documentation: Ensure all documents, including official invoices and certificates, are complete before paying the dealer. This applies to parallel-imported vehicles as well. Inspection: This requires keen judgment. Some cars may be cheap but could be long-stocked inventory with hidden issues. Although the "Automobile Three Guarantees" policy offers protection, legal disputes can be costly and time-consuming. Purchase Tax: After returning to your local area, pay the vehicle purchase tax at the tax office first. Registration at the vehicle management office can only proceed after local tax payment. Out-of-Town Maintenance Service Fees: If some 4S dealerships charge out-of-town maintenance service fees, this is non-compliant, and you can file a complaint with the manufacturer. Note that for after-sales services of vehicles not purchased at the dealership, some 4S shops may offer fewer discounts. For parallel-imported cars, check if nationwide warranty is promised.

What does the U-shape on highways mean?

Highway U-shape refers to a U-turn facility, which is a type of road design. Below are some related tips for driving on highways: 1. Do not drive too fast in the ramp: Pay attention to the turning road signs. The curvature of ramps varies, some are slightly curved, while others can curve up to 360 degrees, which can be disorienting. Therefore, it is essential to reduce speed in the ramp to prevent sudden turns. Ramps are the most accident-prone areas, so always observe the speed limit. 2. Never stop at intersections: When approaching an intersection, slow down slightly in advance to allow time to determine the correct direction. Some drivers go too fast, pass through the intersection, and only realize they took the wrong route afterward. They then suddenly stop or even reverse, which is highly unsafe and can result in fines and penalty points if caught by traffic cameras.

Which lane should I take for driving to the left front?

For driving to the left front, take the middle lane. Below is relevant information about lanes: 1. Introduction: A lane, also known as a traffic lane or carriageway, is a designated path for vehicles to travel on. Lanes are set up on both regular roads and highways, with highways having legal regulations for lane usage, such as travel lanes and overtaking lanes. 2. Lane markings: In many countries, lane markings appear on the road surface. The most common markings are directional arrows. In China, starting with the Beijing Airport Expressway, all newly constructed highways have ground lane markings, especially those related to speed limits. The maximum speed limit is indicated in orange, while the minimum speed limit is marked in white. The newly opened sections of the Southwest Sixth Ring Road, which began operation in 2004, also feature ground speed limit markings. The Beijing-Shijiazhuang Expressway's Beijing section has also implemented lane-specific speed limits.
