Where is the Engine Computer Installation Location for Chery Tiggo 5?

Chery Tiggo 5's engine computer board is located in the U-shaped slot on the passenger side. The engine computer board, also known as the ECU (Electronic-Control-Unit), is referred to as the "vehicle computer" or "on-board computer." It automatically processes input signals from various sensors according to predetermined programs and then outputs signals to actuators, thereby controlling the vehicle's operation. More details are as follows: 1. The main component of the vehicle computer is a microcontroller, which is a circuit board integrating a microprocessor (CPU), memory, and input/output interfaces. The microprocessor is the core component of the microcontroller, converting analog input signals into digital signals, comparing them with stored reference data, calculating output values, and controlling actuators after amplifying the output signals. 2. Vehicles operate under varying road and climate conditions, so the vehicle computer faces a challenging working environment, often enduring vibrations, temperature fluctuations, and humidity changes. The power supply voltage for the vehicle computer varies significantly, and it is also subject to electromagnetic interference from inside and outside the vehicle. Therefore, the vehicle computer requires high reliability and environmental durability.

I just checked the engine control unit (ECU) location of the Tiggo 5 at the repair shop. It's installed on the right side of the engine compartment near the windshield, mounted on the firewall in front of the passenger seat. This black box contains the core of engine control, and its firewall placement primarily considers dustproof and waterproof protection while facilitating wiring near harness interfaces. Last week in our car owners' group, someone mistakenly identified it as a fuse box and removed it incorrectly, resulting in system errors. Actually, after opening the hood, you can see the ECU fixed on its bracket by first removing the plastic cover beneath the wipers. Remember to disconnect the vehicle power before operation, otherwise static electricity may damage the chips. It's recommended that non-professionals avoid self-disassembly, as matching programs require specialized equipment for debugging.

As a longtime owner of the Tiggo 5, I've personally replaced the engine control unit (ECU) of this vehicle. You can see it upon opening the engine compartment, located at the front right near the battery and ABS pump. The advantages of this corner placement are obvious: first, its proximity to the engine facilitates connections with various sensors; second, the plastic shield effectively blocks rainwater. During my last engine bay cleaning, I noticed this area tends to accumulate leaves, which can clog the drainage holes and potentially flood the ECU. The ECU board measures approximately 20x15cm and comes equipped with metal heat sinks. Special care must be taken with the fragile data connectors during installation/removal - last time I damaged the ribbon cable pins by forcing them, ultimately costing me 200 yuan to replace the entire wiring harness.

I've been repairing the Tiggo series for several years. Its engine control unit (ECU) is installed on the inner wall of the engine compartment in front of the passenger seat. This location benefits from short battery power supply lines, and the metal casing can dissipate heat through the vehicle frame. When locating the ECU, you need to remove the black plastic rain trough cover, which is positioned near the coolant reservoir. As the vehicle's control hub, the manufacturer has implemented a double-sealed design. However, in winter, melted snow on the ground can easily cause water seepage, so it's recommended to add a waterproof rubber sleeve. The factory installation is very compact, so avoid haphazard wiring when modifying audio systems or installing additional equipment. Last time, an owner installed extra LED strips on the ECU, which caused signal interference resulting in throttle lag.
