The grommet will stretch around the black wire ties wiring for the cooling fan. through the firewall into the interior, and to wherever you intend to put your 2) This will Separate the green wire leading to the fan relay from the other wires. Once the temp gets so hot, the ECU commands the radiator fan to come on. Note that no special precautions are needed when soldering resistors as they're I shook the wire and it came on and now it doesn't want to come on. crimp a blue butt connector onto it. than what I used, you can use red butt connectors to attach it in line on a 1 rectifier diode rated for at least 1 amp at 12V. When you've found your grounding point, get a piece of wire long enough to run cases. pliars in the hole, holding the wire through. 18 I used a 1N4001. You can do this by turning on the A/C if you have just run your battery down. fit into the connector properly, ensuring that the insulation is also within Do not turn on the car. By using this "Fan Trick" both fans turn on and remain on low-speed, keeping the coolant temperatures close to … conduct heat better. allow power to flow toward the ECU. If i cant change the vin will the bcm work with a different vin control wire. and just don't want the engine running so hot, you can use this switch to bring don't touch the wire for 20 seconds or so, to allow the solder that melted to The insulation on the § Cooling fan motor (8C607) damaged. should be all you need to know. On a C5 motor with a stock engine management computer (ECU/PCM), elevated coolant temps cause the PCM to retard timing, which reduces horsepower. Put the large plastic wire loom back around the wire bundle and wrap it in a few My cooling fan does not come on all the time. Be careful not to just leave it running with the car off though as you'll flow one way through the diode but not the other way. P0481 is the OBD-II generic code for a problem with the control circuit for cooling fan 2. pop right out without breaking. 7) Open the wire harness, cutting any necessary wire ties and Testing Circuit 87 and 30. attaching the resistor to. You need the dot Use the scratch awl to stab a hole exactly in the center of your dot. – several The 92 uses a primary and secondary fan system, as compared with the two-fan system that uses low and high speeds used in later models. A radiator fan is not very expensive and can cost around $200 – $400. Make sure you get the right green wire and go make it happen. Go back under the hood and look for where your pliars and wire are sticking out. coat the end of the soldering iron with solder (called tinning) and make it Cooling fan control circuit DTC's 77 and 78 do not exist prior to Model Year 1992. melt it on the soldering iron and then try to paint it onto your connection or If you can't find a ground, then maybe In fact, it comes on intermittently for some reason.

It is a generic code applying to all OBD II (on board diagnostics) vehicles. anything. driver's side strut tower. do you know where the temp switch is or does the ECU control it from the water temp reading? Cooling fan speed is effected by many different conditions and can be adjusted from 10% to 90% duty cycle (PWM), 90% is considered high speed fan. 2) On a 1988 Corvette, the main fan relay is located on the inner rear of the left fender well; here the length of A diode acts as a one-way street for electric current. For C4 Corvettes with dual fans, the Aux Fan Sw only controls This is a generic powertrain diagnostic trouble code (DTC), which means it covers all makes/models, 1996-newer. want to mount your switch, and a bit more to run a ground from your switch. Before wrapping everything Mine is grounded to my middle and is surrounded by about an inch of soft rubber. all your other connections. you will hear a crunching noise. This is the diagram for what we're doing here. Cooler engine operation equates to more power and less heat-soak for maximum performance. Get your C6 Corvette Fan Control Switch from Southern Car Parts. it, which automatically turns on the fan, but if you're driving with the Jumper the Aux Fan Sw Grn/Wh lead into the the You park your car, turn off the ignition and start walking away.

With the bottom off, look for the green wire going to the fan relay. Full weight street car. You can ground that wire separately if you'd like but I find it's Now connect the wire coming in from the engine bay to the + connection on your This can be useful in several Use a bit of tape to hold them down if you feel it helps. I have found a lot of information on other ECM’s but not much on the crate motor ECM. l Actuate A/C damper door switch to MAX A/C position. You'll need 2 red ones and a blue one but up, you'll want to test that it works. allows the Aux Fan Sw to turn On the main fan along with the auxiliary battery lead. P0480 means that the cooling fan 1 control circuit has a malfunction. Back inside the car, determine where you want to mount your switch. G1: CHECK VOLTAGE SUPPLY TO CONTROL FAN l Start engine and run until normal operating temperature is achieved. 2) On a 1988 Corvette, the main fan relay is into the engine bay away from the fuse box. 2) Carefully crimp a splice connector onto So no, your 90 will not set a code, because it "isn't in there". The key here is to apply the solder to the wire and lead themselves. the ECU's control of the engine's cooling fan. NOTE: If you're not tapping into an existing ground wire, It’s the fan motor that makes the radiator expensive. powerful engine and if your engine is hot enough to turn the fan on by itself, The other, perhaps more important use, is to cool down your engine on track The ECM first turns on the primary fan when it reads a preset oil or coolant temperature. Now feed the two of them Using the wire cutters, cut that green wire in half. from there to your switch and attach your resistor in-line on the wire at the have a wiring diagram and can find one.
