Useful for global variations of the Navara platform.

Multiple pins are dedicated to grounding to ensure signal stability. 2. Critical Engine Sensors

Manages the Exhaust Gas Recirculation for emissions. Safety Precautions When Testing

Usually receives 12V when the key is in the 'ON' position. Permanent Battery: Provides memory power to the ECU.

Use proper back-probing pins to avoid damaging the waterproof seals on the ECU connector.

Crucial for calculating fuel delivery and EGR operation. 3. Fueling and Actuators

Before searching for a diagram, identify your ECU. Look for the label on the aluminum casing, usually located in the engine bay or behind the glovebox.

Located on the high-pressure pump. This is a common failure point; the ECU uses PWM (Pulse Width Modulation) to control fuel pressure here.
