Turn the engine switch off and turn off all electrical accessories. Open the fuse box cover. See diagrams below for details about which fuse to check. Remove the fuse. Check if the fuse is blown - if the thin wire inside is broken, the fuse has blown. Replace the blown fuse with a new fuse of an appropriate amperage rating.

The secondary circuit is the side with the larger terminal pins or wires, and it is what switches the high current circuit to the accessory. 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 ...

The ABS motor relay supplies power to the ABS pump motor. While the ABS is activated, the ECU turns the motor relay on and operates the ABS pump motor. If the voltage supplied to the motor relay (+BM) is below the DTCs detection threshold due to low voltage from the battery/alternator, the DTCs may be stored. WIRING DIAGRAM. INSPECTION PROCEDURE

1992 toyota pickup , blowing efi 15 amp fuse in under hood panel. Check the circuit opening relay, located behind glove box or kick panel on right. Look for signs of corrosion, this fuse only powers the fuel pump and the engine ecu. Read full answer. Sep 20, 2009 • 1992 Toyota Pickup.

The current flows to the c/opn (circuit opening) relay by turning the tr1 on. Then, the fuel pump operates. While the ne signal is input into the ecm, when the engine is running, the ecm turns the tr1 on continuously.

Dual Contact (Single Relay), Ignition Switch Controlled This EFI Main Relay configuration is used on the Conventional eFi system. It uses separate power contacts to supply current to the fuel injector/ignition circuits and the ECU/circuit opening relay circuit. This limits current flow that the ECU power contact must handle.

Connect one pin to earth and the other to the green wire out of the relay. Wiring Diagram: White/Black - Wires to to STA - Starter/ECU Start Signal. White/Red - Wires to EFI Relay - +12v Ignition Switched power (Run through a suitably sized fuse, 10A is usually fine, but depends on your fuel pump).

The HV negative pre-charge relay is momentarily closed and opened. If current flows whilst the relay is open, an HV positive voltage must be present, indicating a fault in the HV circuit. Eventually, all of the relays are open and there are neither positive or negative HV voltages at the respective SMR outputs.

How Circuit Opening Relay Works - 22R-Eliable 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). COR is the thing that you'd hear click behind the glovebox when you're trying to start a first gen 4Runner.

2. Pull the CO relay out and test the secondary winding with an ohm meter, probably should read the same resistance as the primary winding. If bad replace it. 3. If the relay tests OK, figure out why the STA signal is bad. On option is to add a starter relay (or rewire the existing relay) to take the solenoid load off the ignition switch:

There are two relays that are involved, the circuit opening relay located behind the glove box and the EFI main relay located in the fuse box under the hood, the most common problem when there is no fuel pressure is the fuel pump, check all the fuses and substitute the two relays to see if it solves the problem.

Use the drawing to identify pin 3 and pin 5 of the relay. Jumper pin 3 and pin 5 with a piece of wire. -- Remove the circuit opening relay in the junction box by the driver's left knee (that is hard to get to). Look at the drawing on page 9. Identify pins 3 and 5. Jumper these pins 3 and 5 as well.

Two kinds of pins are used (85 & 86) to regulate the coil, and 2 pins are used (30 & 87) to switch power on a single board/circuit. In the case of normally open, when the coil is stimulated, the relay will start the power ON for the circuit. For a normally closed, when the coil is initiated, it will shut the power OFF for a circuit. 5 Pin Relay

The running part that tells the ECM to keep the circuit opening relay closed is the Cam Position sensor. Problem comes and goes. Driving me crazy and can no longer trust truck. Truck still has a airflow valve. Fuel pump pumps fine when you give it power to the blue wire on the circuit open relay. The call out for the fuel pump is .2-3 ohms .

Where is the ECU and Circuit opening relay on a 1991 Toyota Camry with a 3SFE engine? I have (3) sources telling me its under the dash board. I have removed the dash....and it's not visible. I am trying to get to the circuit opening relay to test it.

To prevent this, a second coil is wired to the starter relay circuit so that when you turn the key to START, 12v will be sent to this relay which will in turn power your fuel pump. Once the car starts the key returns to RUN where the ignition side of the COR / separate relay takes over until you turn the car off.

Fuse box diagram (location and assignment of electrical fuses and relays) for Toyota Camry (XV40; 2007, 2008, 2009, 2010, 2011).

The magnetic field created causes the injector to open against spring tension. When the ECU driver circuit turns off, the spring closes the injector valve. There are two common types of driver circuits currently in use on Toyota EFI engines; both of these driver circuits work on the voltage control principle.

Toyota Hilux Wiring Diagram. Print the electrical wiring diagram off and use highlighters to trace the signal. When you make use of your finger or perhaps follow the circuit with your eyes, it is easy to mistrace the circuit. One trick that I use is to print out exactly the same wiring diagram off twice.
