With the pinout mapped, Sam traced a faulty crank sensor harness and repaired a corroded connector. The car fired, idled rough for a bit, then settled into a happy purr. On the way to a late-night burger run, Sam thought about sharing the cleaned-up pinout and photos to help other Zexel owners — but first, more testing to make sure their notes matched across engines and years.

Calibration points that adjust engine behavior during cold starts.

Before looking at pinouts, you must identify the connector type. There are two main generations: Keeps the ECU memory alive for diagnostic trouble

If your ECU does not match the table above:

For those performing deep repairs, technical documents like the ZD30 ECU Pinout PDF or community guides on NefMoto provide granular details for specific part numbers.

Once they had a working map, Sam compared notes to a Zexel service manual and a couple of forum pinouts for that ECU part number to confirm differences between variations. They taped the photo, a printed pinlist, and voltage ranges inside the glovebox.

Nissan Zexel ECU (Electronic Control Unit) was commonly used in diesel Nissan models like the Patrol (Y61) Input signal from the Accelerator Pedal Position (APP)

Sam had just inherited an old Nissan 240Z from their uncle — a sleeping beast with a rumpled paint job and a wiring harness full of mystery. The engine turned over but wouldn’t run right. In the garage by noon, Sam found the ECU: a rectangular metal-cased Zexel unit stamped with part numbers and a connector full of pins. No wiring diagram came with the car, and online searches returned a scatter of forum posts. Sam decided to treat the problem like a puzzle and learn the ECU’s pinout.

This article serves as your definitive guide. We will dissect the history of Zexel ECUs, explain why their pinouts differ from Bosch or Denso systems, provide a detailed pin-by-pin breakdown, and offer practical advice for diagnostics and swapping.

Unlike modern petrol ECUs that focus heavily on complex drive-by-wire matrices and multi-stage variable valve timing, Zexel diesel units act as the core manager between physical driver demands (accelerator pedal sensors) and exact fuel metering.
