Where is the computer board of Haval F7 located?

[MacLincoln]

Haval F7's computer board is located on the sub-instrument panel. Fuel consumption calculation method: After resetting the mileage data recorded by the vehicle's dashboard, the onboard computer automatically calculates the vehicle's fuel consumption based on the recorded mileage and fuel consumption data. Definition of constant-speed fuel consumption: Constant-speed fuel consumption is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. During road tests, it is necessary to follow the national standards for test conditions, test methods, test road selection, etc. Test conditions include: the load of the test vehicle, the accuracy of test instruments, fuel, tire selection, ambient temperature, humidity, air pressure, wind speed, etc.

When I first drove the Haval F7, I was also curious about where the ECU was located. Actually, it's near the battery on the left side of the engine bay—just pop the hood and you'll see a black metal box. Be careful though, the box is covered with connector wiring harnesses, and damaging them can be costly to repair. Once while washing the car, I noticed a waterproof label on the box cover, and the mechanic said it's prone to short circuits when handled in rainy conditions. In older models, the ECU was under the plastic cover behind the wipers, but its location changed after the 2020 model year. If you can't find it, try lifting the passenger-side floor mat—sometimes the auxiliary control module is hidden behind the steel panel inside the center console. The safest way is to check the manual, as the position may vary depending on the configuration.

Last time at the repair shop, I watched the mechanic remove the Haval F7's ECU, and its location is indeed carefully considered. In mainstream models, it's hidden behind the battery in the engine bay—the aluminum box with cooling fins is the ECU. Engineers placed it here primarily for better heat dissipation and to minimize interference by keeping it away from the engine. However, mud and water kicked up by the front wheels can accumulate around the box's seams, so it's advisable to check the condition of the sealing strips. A friend at a modification shop mentioned that higher-end models have a body control module inside the driver's footwell, but that's not the main ECU. Remember to disconnect the battery before touching any wiring—operating with power on can blow fuses.

Last month, I cleaned the ECU of my Haval F7 by myself, and its location is actually not hard to find. Open the front hood, and there's a palm-sized black box next to the battery with about twenty to thirty wires plugged into it—that's the one. The newer version of the ECU has been relocated to the inner side of the firewall, requiring the removal of the plastic cover under the windshield to see it. Before starting, be sure to disconnect the negative battery cable, and it's best to wear anti-static gloves. I noticed the box has drainage grooves at the bottom, which can easily get clogged with leaves during the rainy season. Non-professionals should avoid disconnecting the connectors—last time, I bent a pin, causing the ABS light to stay on.

My car enthusiast group has discussed the location of the Haval F7's ECU. It is typically positioned above the left wheel arch in the front compartment, suspended and secured with four rubber pads for optimal vibration damping. According to real-world tests by fellow enthusiasts, the 2019 model also has a small controller module located above the accelerator pedal on the driver's side. Interestingly, the metal casing of the ECU provides electromagnetic interference shielding, but prolonged rough driving can loosen the mounting screws. When modifying the lighting system, it was discovered that the wiring modification points are right next to the ECU box, with the blue No. 35 relay being particularly crucial. It is recommended to check for any oxidation at the wiring terminals during each maintenance service.

According to the repair manual, the ECU of the Haval F7 is located behind the battery tray in the engine bay, and the air filter box needs to be removed to get a full view. The positioning considers three factors: proximity to sensors for minimal signal loss, avoidance of the high-temperature exhaust manifold, and a relatively spacious maintenance access. During the last ECU upgrade, it was noted that the new version uses three Torx screws for fixation, which are more difficult to remove compared to the hex screws of the older version. In fact, there is also a gateway module behind the glove box on the passenger side, which, strictly speaking, is not the main ECU. Beginners should not tamper with it themselves; the pins on the ECU are more delicate than those on a phone charging port.
