The Nissan ZEXEL ECU is a computerized engine management system designed by ZEXEL, a leading Japanese company specializing in automotive electronics. The ECU is responsible for controlling various aspects of the engine, including fuel injection, ignition timing, and emissions. The ZEXEL ECU is used in a wide range of Nissan vehicles, including the popular Skyline, GT-R, and Silvia models. The ECU is responsible for controlling various aspects
Find a Black/White wire (pin 23 or 103 typically). That is sensor ground. Attach your multimeter black lead there. Then probe other pins with positive lead. Any pin showing 5V or 12V relative to sensor ground is a power supply. Any pin showing continuity to chassis ground (with key off) is likely an actuator return.
Before the ECU can process any sensor data, it must establish clean power and solid ground connections.
