When do the Lights Come On on a Toyota RAV4?
The coil will be energized whenever the fogs are on, and you connect your driving lights to the normally closed contact. That would work, and there is no risk of damaging the ECM, but if you ever turn off the fogs, your driving lights will come on with the parking lights and low beams.
How does the headlight switch work on a Rav 4?
Nowadays, the headlight switch sends signals to the ECM, and the ECM in turn operates the various relays. So we can no longer follow an action to the resulting reaction. After examining the drawings the best GUESS that I can give is to look for a ground on Pin #2 of the DRL #4 relay when the high beams are on.
Where is the relay on a Toyota Rav 4?
This relay is located under the hood in relay block #2, on the right side fender area. As a second choice, you should also find a ground on Pin #5 of the same relay when the high beams are on, but this point should read 6 volts when the DRL’s are on.
Where does the 6V come from on a RAV4?
If you connect one side of the coil to +12v and the other side to relay DRL #4 Pin #2, where does the 6V come from. That is the voltage you would see on PIN #5 or the relay, which is connected to one side of each high beam filament. I.E.
Is the Toyota RAV4 4 wheel drive in winter?
Granted, winter ain’t what it used to be, at least not recently, but with the clearance of the RAV4 and the pull of two front tires, I have no plans to purchase another four wheel drive. No one talks about the lock hub in the front, because Toyota makes more money selling 4 X 4s.
How does DRL 4 work on a RAV4?
When DRL #4 operates it grounds the common point of the two high beams and they both get the full 12v. That is why I recommended connecting one side of your relay coil to Pin #2 of this relay since that is where the ECM signals the relay to operate. (the other side of the coil goes to +12v)
