Feeds line data to diagnostic scan tools (often using early Nissan Consult-I or early K-Line OBD protocols). Step-by-Step Guide to Verifying an Unknown Zexel Pinout
The (Engine Control Unit) is a critical management system found in various Nissan diesel vehicles, most notably the Nissan Patrol Y61 and Navara D22 equipped with engines like the ZD30 , YD25 , and TD27 . Zexel, originally Diesel Kiki and now part of the Denso Corporation, produced these ECUs to precisely control rotary fuel injection pumps (such as the VP44) and optimize engine performance. Understanding the Zexel ECU Pinout
If the car cranks but won't start, checking for power and ground at the Zexel ECU pins responsible for the pump solenoid is the first step. nissan zexel ecu pinout

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).
