OEM Electrical Control Relay for Infiniti/Nissan ⚡

This compact switching unit lives in the engine-bay fuse/relay box and feeds power to key systems such as the ECM, fuel pump, cooling fans, ignition, or A/C (varies by trim). Built to factory spec, it delivers stable voltage, low heat, and quiet, reliable cycling—ideal as a direct-fit replacement relay for many Infiniti/Nissan platforms.

Why it’s needed ?

The ECU uses this relay to control high current safely with a small signal. It protects wiring from arcing, keeps switches from burning, and ensures clean power to sensitive modules and motors for smooth starts and steady drivability.

How it works ?️

When the coil sees 12V, a magnetic field snaps the contacts shut, sending battery power to the target circuit. Low-resistance silver alloy contacts minimize voltage drop, while the sealed body helps block moisture and vibration for long life.

If it fails ?

Symptoms include hard start or no-start, random stalls, dead radiator fans, A/C inoperative, intermittent power loss, repeated blown fuses, clicking from the IPDM, or a parasitic drain. Continued driving can overheat the engine, stress the fuel pump, and trigger warning lights.

Pro tips ✅

Swap with a like relay to confirm, check coil resistance with a multimeter, verify control power and ground, and inspect terminals for heat marks. Seat fully in the socket; keep a spare in the glovebox for roadside fixes.
