How does circuit opening relay work in Toyota 4Runner?
PLEASE DOUBLE CHECK WIRE COLORS AND SCHEMATIC AGAINST YOUR OWN FSM BECAUSE SOME TRUCK WIRING MAY TRANSITION DURING A YEAR. The relay prevents unwanted, unsafe fuel flow (i.e., in case of an accident when fuel line ruptures, engine stalls, airflow stops and COR interrupts power to the fuel pump).
What makes a Toyota 4Runner a good off roader?
This generation of 4Runner drives more like a truck than your typical SUV, but that shouldn’t be a problem for most off-roaders.

How can you tell if a Toyota relay is open or closed?
You can test the relays with battery voltage, and a continuity tester or automotive light bulb and socket. Simply power up the primary circuit with the battery, and then check the secondary circuit to see if it’s open or closed.
What happens to the secondary circuit on a Toyota?
When the primary circuit is powered, a Normally-Open relay closes the secondary circuit. Cut power to primary, and the secondary side returns to its state of being normally open. A Normally-Closed relay opens the secondary circuit when the primary is powered.
Which is the active pin on a Toyota relay?
87 = A = ACTIVE (12v flows to this pin from pin 30 when the relay energises) (The above is for a four-pin relay. For a five-pin, there will be another pin, 87A, which will be connected to pin 30, thus receiving 12v, when the relay is NOT energised).
