The Engine Control Unit (ECU) acts as the brain of your vehicle. For many classic Nissan diesel and turbocharged platforms, Zexel control units manage everything from fuel injection timing to diagnostic communication. Mapping a is essential for engine swaps, custom wiring, and diagnostic troubleshooting.
What is the printed on your Zexel ECU casing? What engine model or vehicle platform are you working on?

While specific pin numbers can vary by model year and regional market, the Zexel ECU (frequently found in the and Navara D22 ) typically follows these primary signal patterns:
| Pin # | Signal Name | Description | | --- | --- | --- | | 1 | DIAG | Diagnostic connector | | 2 | CANH | CAN bus high | | 3 | CANL | CAN bus low | | 4 | K-LINE | Communication line | | 5 | L-Line | Communication line | | 6 | VCC | Power supply | | 7 | GND | Ground | | 8 | N/C | Not connected | | 9 | N/C | Not connected | | 10 | GND | Ground |
Adjusts fueling based on engine warmth.
Check the . Zexel systems often rely on an external ECCS/ECM relay to flip high amperage power to the unit.
Connect the black meter probe to a known good chassis ground point. Turn the ignition key to the ON position.
A pinout is a technical map of the electrical connections on the ECU's multi-pin plug. Each pin corresponds to a specific sensor input, actuator output, or power supply line. For the Zexel units found in Nissan diesel engines (particularly the ZD30DDTi), the wiring is complex due to the integration of fuel metering, timing, and security systems like (Nissan Anti-Theft System).

For automotive electricians, diesel tuners, and Nissan enthusiasts, few tasks are as daunting yet as critical as deciphering the . If you are troubleshooting a no-start condition, building a standalone wiring harness, or diagnosing a persistent error code on a classic Nissan diesel (especially the legendary TD42 or RD28), you have likely encountered the mysterious black box made by Zexel.
The Zexel injection pump relies on a closed-loop feedback mechanism to meter fuel.
