Nissan Zexel Ecu Pinout -
Understanding the Zexel ECU pinout is crucial for diagnosing and modifying Nissan diesel engines, particularly the ZD30 and RD28 series often found in the Nissan Patrol and Navara. These units are integrated with the Nissan Anti-Theft System (NATS), making electrical accuracy vital for starting the vehicle. Common Nissan Zexel ECU Pin Assignments

| Pin No. | Function | Description | Wire Color (Typ) | | :--- | :--- | :--- | :--- | | 1 | Battery Positive (+12V) | Main power supply (Unswitched). | Red / Red-White | | 2 | Ground (GND) | ECU Main Ground (Chassis). | Black / Black-White | | 3 | Ignition Switch (IG) | +12V when key is ON. Powers the ECU logic. | Blue-Red | | 4 | Ground (Sensor) | Signal ground for analog sensors. | Green-White | | 51 | Battery Backup (+12V) | Keeps KAM (Keep Alive Memory) alive. | Red-Blue |
The 14-Pin Pinout:
While specific pin numbers can vary by model year and regional market, the Zexel ECU (frequently found in the Nissan Patrol Y61 and Navara D22) typically follows these primary signal patterns:
