A Nissan Zexel ECU pinout is a critical reference map used to identify the specific function of every terminal on the Electronic Control Unit (ECU) connector. These units were frequently used in older Nissan diesel models, such as those with the ZD30 engine found in the Nissan Patrol or Navara. Key Zexel ECU Pin Assignments (ZD30 Example)
Input from the Mass Air Flow sensor for air intake measurement. 44, 47 Crankshaft Position Input and ground for the Crankshaft Position (CKP) sensor. 18 Check Engine Light
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 NATS (Nissan Anti-Theft System). Core Pin Assignments (Example: ZD30 ECU)
| Pin # | Signal Name | Description | | --- | --- | --- | | 1-8 | Analog Inputs | Oxygen sensor, airflow meter, and fuel pressure sensor | | 9-16 | Digital Inputs | Vehicle speed sensor, brake switch, and clutch switch | | 17-24 | Output Drivers | Fuel pump, radiator fan, and AC compressor | | 25-32 | Injector Outputs | Fuel injector control for cylinders 1-6 |
Pins 33, 40, and 53 manage timing and fuel quantity on VP44 Zexel pumps. Glow Plug Indicator: Pin 16 activates the dashboard light. Intake Air Control Valve: Pin 2 controls the solenoid. A/C Relay: Diagnostic and Programming (K-Line) For bench testing or reading fault codes: K-Line (Data): Pin 42 or Pin 88 is used for OBDII communication.
