Zamyad Z24
The Nissan Junior built in Iran for fifty-five years, and for most of that time the commonest working vehicle on Iranian roads — an owner-operated one-tonne pickup maintained by its driver, long out of any warranty, and therefore exactly the population that reads its own codes.
The badge on the grille says ZAMYAD and the engine underneath is Nissan's. That split is the most useful thing to establish on one: the running gear is the third-generation Nissan Junior's (N140/141), so Nissan Z-series material describes the engine, the gearbox and the rear axle directly, while nothing published under the Nissan badge describes the car — Nissan stopped building it in 1982 and everything after that is Iranian.
Two dates change what a scan tool can do with it. The car was carburetted until 2006 and multi-point injected afterwards, so a pre-2006 example has no engine management to interrogate at all and diagnosis is compression, timing and fuelling. And the Iranian injection is multi-point, where Nissan's own Z24i is throttle-body — so the fuel-delivery half of Nissan documentation describes a different system even where the block does not.
The last blue one was built on 4 October 2025 and the line did not stop. The EX, sold as the Nissan Extend, is the same chassis, gearbox and rear axle with a cab sixteen centimetres longer — but its engine is the M24 and not the Z24, which is the one thing about the change a reader diagnosing one needs to know: the outgoing car makes 100 hp and 190 Nm and the new one 94 and 187, from a different block. Everything behind the bulkhead interchanges and the engine number is what settles which you have.
Nothing about any of this reduces the fleet, which is enormous and mostly older than the injection.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
