Fan problems fd3s
Hey People i have some Major radiator fan Problems !!! I looked and studied the fan function and wiring etc But they won't start at 105 degrees, checked my sensor thermo switch relay etc. I put The fan pin from the Ecu on ground and the fans are running then I turned my ac on the the second stage was running so I grounder my thermo switch and the 3. stage was running !! So the three stages are working The only thing I didn't check was the el-unit but I cannot find it Can someone tell me where to look for the EL UNIT ?? Or some advices Thanks

Thx for a quick response !!! I didn't find that silver box I have a Japanese version! But it should be the Same right ???
What do you mean the right connector ?? The el unit have 16 pins and 2 rows the black box have less pins ...???

like I said, the EL unit and the recall box have the exact same connector. But, if your car does not have the recall box installed then you don't have to worry about it.
The recall was a mod that dealers were supposed to install that does something to how the fans react or something or other. I'm not exactly sure.
honestly, I don't know if the Jspec cars are the same.
But, what you can do it for that 16 pin connector you do have going to the black box, look at the wire and color code them to see if that's it.
Also, I do not think the EL unit is the source of your problem. I think it's the relays.

I looked at the black box and compared it with the amount of pins and wire colors in the wiring diagramm it ain't the same!!
On the diagram goes the harness from. The Ecu connector to the fan relays and between them is the el unit connected !!
I cannot find that unit that's the only thing I didn't checked,
I don't thing that the relays are broke because I groundet the pin D3 from the Ecu connector and the fans are working fine !!!

Oh so it's just a signal for the idle?
I'm running apexi power fc, could that be a failure ? The Ecu itself ??
Because I checked the 4 relays and they are working, the thermo switch is working
Looked at the power fc hand control and got 105 degrees water temp.
Could it be that the Ecu is not responding on that ?
A nother question there is one cable on the left side where the oil filler neck is
Is that cable for the add cooland??

Ok do you have a datalogit or someone near you with one
The fans may be set to turn on later then they should be
Second is double check those relays there are 4 of them 3 that are the same and one different thats for the ac
The 3 that are the same 2 are controlled by the ecu and one by the thermoswitch buuuut the themoswitch speed is just a ground so if the other two temp based ecu controlled relays are bad then the thermoswitch wont work
Ive had one of my fan relays go bad before good luxk and get back to us
Also you can try replacing the relays use the thermoswitch relay and replace one of the other relays see if the fans feel like kicking on its easier if you had a datalogit cus you can control when the fans switch on so its easier to play with a cold motor

Thank you for your comment !!!
I will take your advice and will replace and check those 3 relays !!
I have a guy with a Datalogit but he is kinda busy so will wait till he have some space and give me his Datalogit !!
Could it be the Ecu it self ???? A broke Ecu?
I had it once tuned and the tuner asked me why the fans don't work !!! I suggest he tried Ty reduce the temp. On Datalogit for the fans
So I searched for the problems but never found one!!!
The only way I cool my engine is with the ac !!! The only way my fans are working, I drove today with 30 degrees weather temp. But my water temp. Was max. 87 degrees I think that's a good temp. For a Rx or???

Hey you guys.....
I was on my way to check the fan problems with the Datalogit...
The next problem came up, drove into the garage and the engine died!!!
Looked at my power fc and noticed that it was death, also was my boost controller death
So I went to the diagnostic connector and added a cable from batterie plus to the
F/P pinout port ( fuel pump relay coil) and suddenly my power fc and avcr boost controller
Got juice and works fine, I even can start my engine with that cable ???!!!
Is that normal
I'm kinda lost, I have this electrical problems all the time
Is some relay broke or the ignition switch ? Or just a broke cable ??
