Zexel Ecu Pinout - Nissan

The Nissan Zexel ECU pinout is a bridge to an era of mechanical-meets-electronic diesel engineering. While newer common-rail systems dominate today, thousands of Nissan Patrols, Terranos, and Cabstars still rely on these rugged but finicky ECUs. By mastering the pinout, you empower yourself to bypass corroded wires, bench-test a dead ECU, or even adapt a modern standalone system (like a Link or Haltech) to the old Zexel pump.

Since "Zexel" is used across many models, always verify your unit using the part number on the sticker: Nissan Patrol (Y61): Often looks like 23710-VC616 (Zexel 407917-061). Nissan Terrano (2.7 TDI): Often looks like 23710-7F403 (Zexel 407913-120). Bench Testing: nissan zexel ecu pinout
