Where is the Pajero 4WD ECU located?

The Pajero engine ECU is located behind the instrument panel. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Precautions for using automotive engines are as follows: 1. Avoid driving in neutral gear: The engine itself has a fuel cut-off function during deceleration, and driving in neutral is actually detrimental to fuel economy; 2. Pay attention to observation when using the vehicle. If oil is found on the ground, determine whether there is an engine oil leak and communicate with the car 4S store in time to eliminate potential safety hazards; 3. For vehicles equipped with turbochargers, do not turn off the engine immediately after high-speed driving or climbing. Let it idle for 10 minutes before turning it off. Vehicles with turbochargers form carbon deposits several times faster than naturally aspirated vehicles; 4. When water is mixed into or absorbed by the brake fluid, or impurities or sediments are found in the brake fluid, it should be replaced or carefully filtered in time. Otherwise, it will cause insufficient braking pressure and affect the braking effect.
As a long-time Pajero owner who frequently tinkers with the 4WD system, I can share that the Pajero's 4WD control module is typically located in the left corner of the engine bay or near the firewall area - the exact position depends on the model year. For older V6 series models, it's usually mounted near the fuse box, and you can access it by removing the trim panel. I remember once when my 4WD failed during off-roading, I urgently popped the hood to locate it and found it was just clogged with dust - a simple cleaning fixed the issue. Newbies should note: never tamper with wiring randomly. Always turn off the engine first to avoid electric shock or system damage. If unfamiliar, consulting the manual or searching online for location diagrams is safer. Ultimately, knowing this can save significant repair costs and boost off-road confidence.
Having worked in the auto repair industry for most of my life, I've encountered numerous issues with the Pajero's four-wheel-drive system. The computer module is usually hidden in the central tunnel beneath the dashboard or on a bracket near the battery box in the engine compartment. You'll need to lift the carpet or remove the trim cover to spot it. When abnormalities occur, don't rush to dismantle—first check if the connector is loose or burnt, as this is a common failure point. I recommend using a multimeter to test the voltage, which should normally be around 12V; values too high or too low can easily cause problems. If you lack the tools, prioritize safety by visiting a professional shop. Remember, regular dust cleaning during routine maintenance can prevent future issues and avoid breakdowns on long trips.
As a beginner in off-roading, I was quite confused when searching for the 4WD computer module on my Pajero for the first time. Online sources mentioned it's under the cabin carpet or beneath the seats. When I lifted the rear carpet, sure enough, I found a black box attached to the floor. Later I learned its position varies slightly across different trims - mid and low spec models might have it near the front passenger seat. Remember to disconnect the battery before working on it - just unplug the terminal for safety. If you can't locate it, try posting an engine bay photo on forums to ask other owners, saving yourself unnecessary hassle. This experience helped me understand my vehicle better.
