Water ingress or pin backing (where pins push out of the plastic connector housing) can cause severe driveability problems. A proper bench test setup for Zexel ECUs

While exact pin locations vary by engine model (e.g., a Terrano TD27Ti versus a Caravan QD32ETi), Zexel ECUs share a standardized functional architecture. Pinouts are broadly categorized into four primary groups: Power/Ground, Sensor Inputs, Actuator Outputs, and Communication. 1.
