The trunk lock block BMC of the Great Wall H2 is located inside the center armrest. Below is relevant information: Exterior: The front face of the Haval H2 adopts the new Haval family grille, featuring a prominent red HAVAL logo and a large-mouth front air intake grille. The mesh is decorated with chrome trim, creating a bold yet stylish appearance. The headlights of the H2 are a standout feature of the front face, with parallelogram-shaped headlights using a smoked design, complemented by star-like LED daytime running lights below, giving it a touch of luxury car aesthetics. Interior: Compared to the exterior, the interior of the H2 follows a relatively minimalist style, extensively using bright silver materials and wood trim to enhance the premium feel. The H2 generously features a leather multifunction steering wheel, with a three-spoke sporty design that is thick and sturdy, offering excellent grip.

I remember when I last dealt with the Great Wall H2 tailgate lock mechanism issue, I found the Body Control Module (BMC) located under the driver's seat. You'll need to remove the footwell trim panel on the driver's side - it's behind the metal bracket to the right of the accelerator pedal, a black square box with connectors. This unit controls the entire vehicle's electronic locking system, including the tailgate switch signal. When my locks malfunctioned before, I opened it up myself - I'd recommend disconnecting the battery negative terminal first, unlike my first attempt which triggered the alarm. By the way, the physical tailgate lock mechanism is inside the tailgate's plastic cover panel, but for electrical issues, always check for oxidation or loose pins in the BMC connector first.

Based on the experience of disassembling over twenty H2 models, the BMC is typically located in the circuit concentration area at the lower left corner of the cockpit. The specific procedure involves removing the lower steering wheel cover and then unscrewing the metal bracket to locate it. The module is about the size of a cigarette box and is attached with a silver heat sink. Important reminder: when encountering trunk lock malfunctions, don't rush to dismantle the tailgate, as key signals and electronic control logic rely on BMC processing. Once, while helping a fellow car owner troubleshoot, it was discovered that a wiring harness connector was short-circuited due to wear from a floor mat. If you're doing it yourself, prepare a T20 screwdriver and plastic pry bar, as the working space is extremely tight.

The BMC of the Haval H2 is located in the cavity near the brake pedal. The mechanic showed me its position during the last maintenance—you need to lean your head into the driver's seat to see it. The module is connected to several wire harnesses, and the thickest one with blue and gray connectors controls the trunk. A friend at the 4S dealership helped me check the repair diagram—models after the 2017 version have added dust-proof rubber sleeves, making it even more concealed. Non-professional car owners are advised to visit a repair shop directly for inspection. BMC failures often come with symptoms like malfunctioning windows, so don’t make the same mistake as my neighbor who misdiagnosed the issue and needlessly replaced the tailgate lock.

Checked the H2 wiring diagram and confirmed the BMC is located on the metal beam to the left of the steering column. When working on it, you'll need to remove the lower dashboard panel and can feel the rubber-mounted aluminum housing with your fingers. The module is less than fifteen centimeters from the driver's seat fuse box. To address the trunk lock issue, first test whether its power supply voltage is normal. Last year, when modifying the power tailgate, I specifically reinforced the wiring harness in this location, as vibrations on bumpy roads could cause poor connections. The trunk lock itself isn't expensive, but BMC failure can disable the entire vehicle's electrical system, so it's best to have a diagnostic tool ready to check for trouble codes.

Our car club's actual measurement shows that the H2's BMC is fixed on the back of the steering column bracket. Experienced drivers suggest clearing the driver's seat of clutter first, then lying down and using a flashlight to check the protruding black module above the steering shaft. The ground wire is yellow-green, and the positive power supply is drawn from the driver's side fuse box. When dealing with abnormal noises, we found that the module bracket tends to loosen, causing poor contact. Beginners should avoid prying the casing forcefully, as the internal circuit board is very fragile. By the way, waterproofing is essential during the rainy season—I've seen cases where car wash leaks burned the BMC, and the repair cost was enough to buy three new tailgate locks.

What to Do When the Remote Control of the Car Key Fails?

Install a new battery or go to a 4S shop specifically to have the battery installed. Open the key, dry the inside with a dry tissue, or use a hairdryer to dry it. If the water damage is severe, it is recommended to get a new one. If the car key has lost some of its functions due to prolonged contact with electronic products such as mobile phones or iPads, it is recommended to get a new one.

What Causes the Humming Noise at 60 MPH?

The possible reasons for a humming noise at 60 MPH include: 1. Excessive tire pressure causing abnormal noise: Daily driving requires maintaining tire pressure within the standard range. Overinflated tires reduce shock absorption performance and significantly increase tire noise; 2. Abnormal tire wear causing noise: The tread area of the tire contacts and rubs against the ground. If the tread wears unevenly with irregularities, it can produce a humming sound; 3. Damaged wheel hub bearings causing noise: Worn wheel hub bearings generate a humming noise, primarily due to long-term use leading to wear and looseness. To protect wheel hub bearings, avoid severe impacts on the wheels and prolonged driving through water during daily use.

Where is the cigarette lighter in the Avalon?

The cigarette lighter socket in the Avalon is typically located in the center console area, marked by a cigarette-shaped icon (or voltage value). Here are some relevant details: 1. Powertrain: The seamless integration of the ECVT transmission, electric motor, and engine is unparalleled, delivering smooth acceleration and deceleration between 0-100km/h with almost imperceptible gear shifts. Both throttle and brake tuning lean towards comfort, providing gentle feedback in Normal mode with relatively low acceleration and deceleration G-forces. 2. Exterior Design: The Avalon's restrained styling maintains a mature, sophisticated appearance while incorporating substantial Lexus design elements. The front fascia features a similar spindle-shaped grille design but with more aggressive styling, complemented by subtle wide-body effects on both sides that give the vehicle a substantial presence.

Can the Changan CS75 use 5w40 engine oil?

Changan CS75 can use 5w40 engine oil, but the manufacturer recommends using 5W30 engine oil for better performance as per the manufacturer's instructions. The specific details are as follows: Using 5w-40 engine oil can make the engine quieter, but it will increase fuel consumption. 5W-30 has better fluidity than 5w-40, which helps in reducing fuel consumption and dissipating heat from the engine more quickly. Related information is introduced as follows: The difference between 5w30 and 5w40 engine oil is that the higher the viscosity of the engine oil, the more fuel the engine consumes, and the louder the noise, but the better the sealing performance. Therefore, when choosing engine oil viscosity, the age of the vehicle should also be considered. The engine components of a new car have very small gaps, so engine oil with lower viscosity should be chosen, while vehicles with severe engine wear should choose engine oil with higher viscosity.
