- How ECM Controls Cooling Fans describes the relationship between the ECM and the FAN control module. This same principle is used to control blower motors and fuel pumps.

Thank you for putting the waveforms in this video; very helpful!
VERY GOOD VIDEO PLEASE DO MORE VIDEOS LIKE THIS ONE I HAVE LEARNT A LOT FROM IT THESE ARE THE VIDEOS THAT ARE VERY EASY TO UNDERSTAND AND THANK YOU FOR YOUR TIME .
+8power0 thank you. Mandy.
Thankyou for posting this diagram. I had an axillary switch and it drains the battery.
I DIY everything back to oem using your diagram video and was able to connect my fan module. Thanks
Great, glad my vids were able to help you out. autodiagnosticsandpublishing.com
Thanks for sharing your experience with us!
good video! also, what software do you guys use for the old/new narration of txt? thanks!
I'm your old subscriber and this channel is awesome 👍 thanks for making videos stay blessed.😇😇👍
+arslan rajpoot thank you
excellent sir...
Very nice video 👍👍👍
+arslan rajpoot ,😎 thanks
Love these types of videos big thumbs up 👍

Good !
Good video and info as always thank you for sharing. cheeeeeeers
Video was cool, thanks u pipo r making our thru👏
Hi, thank you for the video. Can one use say a Temp switch (thermostat in oil radiator) to output the signal to the module to control the speed of the fan?
It's best to use an Arduino for that. See my Arduino videos on this channel.
so what you do if you dont have this performant machinery to test the module, im sure most of viewers dont have this so can you replicate the pwm signal trough a rc radio receiver ? they work on pwm signal, was curious if I can have same result.
If you don't have this unit you end up replacing the parts. If that doesn't solve your issue, then your loss. If you work on your own car or are a professional technician, then you need your tools. Here it is in case you need it.

So the yellow wire is get signal from the temperature sensor?
Cool !
Thank you for your excellent presentation. I have a 2005 Mazda MPV ES. The radiator cooling fan it's a dual fan system. One of the fan not working, the other it is OK. The fan that doesn't working has 4 wires. How to test that fan with 4 wires to make sure it's bad?
U need a wiring diagram and identify those wires.
I have cuestion please sr. I have a DS 213 mini osciloscopio and I am just wondering if it would be possible to use the "waveform generator" function to put frequency or to do something similar like PWM. I am not totally sure about it. Thank you for this video tutorial.
No, a waveform generator will never give you PWM. Not even a 555 timer will give you PWM. Pulse width modulation needs a dedicated circuit. See my PWM BI Directional Controller .

On top of it, this unit has a huge driver transistor to boot. Control almost anything with it.

good explain I need thanks prof
👍
This is great -- it let me confirm what I was guessing about this dumb FCM which seems to give out regularly. I'm thinking of interpreting the PWM with an arduino-like microcontroller and driving my own big fat super-low-resistance FETs to run the fans.
That'll definitely work just fine. In fact I have an Arduino project here just like that. Look it up.
I'm hoping to use one of these Fan control modules in an older car. Can i hook the trigger wire to a temp sender or override switch if i don't have an ecm?
Yes, to a temp SWITCH, not a sensor. The switch has to be calibrated to say 180 deg F. This is s typical fan turn on temp.
Also, see my series on Arduino. You can do all that with a $10 Arduino.
Thank you for the information. Do you happen to know what continuous amp rating these are suitable for?
@@ADPTraining😢😢😢😢
@adptraining how does the second channel is working ? how to trigger channe 1 and channel 2 with 2 temperature levels ?
Channels 1 and 2...?????
What do you mean.
@@ADPTraining you have 2 output channels on the controller, to manage 2 Fans
@@florentviolleau6716 That particular Fan Control Module (Gates FCM102 is an aftermarket version, can't find the Calsonic Kansei original) doesn't output different signals for the two fans. The two two-pin connectors, one on the bottom, one on the side, are so it can control two fans, but they both get the same voltage. Check the block diagram and explanation at 1:12.
Hello im asking that pwm bi directional controller is for sale. If for sale where can buy. Thank you

Please advice how to test the fan control module is working or not, can we use multimeter to check that ? . Thank you
Yes you can
@@ADPTraining Thank you for reply, you should make a UA-cam showing how to test the fan control module by a simple way, multi meter (which everyone have), that will be very useful and many people will watch it.
I have mitsubishi outlander 2003 ( first model), used this module.
Fans not working, I suspect control module but find that carbon brushes inside fan motors have worn down to zero and commutator damaged in the process.
Car has 220,000km assume original fans, so can expect fans brushes to need replace around 200,000km. I have not yet tried control unit on new fans so dont know if it has damage also. Fan motors not really designed to take apart but can do fairly easily just by
bend out metal where its pressed in on rear of motor.
Regarding video, excellent info, would be interesting to see what signal the ecu of a car actually outputs to control the fan, that pulsing of the motor speed at certain on/off percentages of the pwm I would doubt is used by ecu, I dont think the fans pulse the speeds in a car.......I could be wrong.
A 2003 is an older car. That's ON and OFF circuit.
@@ADPTraining thanks for reply but its exact same controller using variable speed
Sir ,, if the fan is prematurely engaged. Is it the premature signal from ECU? Or the module is bad?
Share ur opinion sir..
Thanks
Prematurely? Well, it could be either. But in real life if premature it's probably a module problem. autodiagnosticsandpublishing.com
@@ADPTraining thank you for reply
I always thought that the air con controller is built into the ecm?
The ECM controls the compressor clutch.
Could this work as a replacement of another fcm of another car for example a volvo?
Yes, but have to rewire.
@@ADPTraining thank you so much. Actually i think is the same wireing because 2 big cables are for power and ground and a 3th for signal.
Is possible to control the fan from inside the car what should i use

Cooling fans stop working mechanic said ecm replace with new flash one, later down the line unplug battery cooling fans stop working again help please
Reflash won't solve you issue.
I've recently replaced two of these fan control modules on my car. First the factory one failed after fifteen years, then the non genuine replacement failed within two months, so I spent $388 to get a new genuine Mitsubishi unit.
Sure, OEM is the way to go. Non of these aftermarket electrical parts work at all.
And how we can increase the speed of the fan?
Two ways, resistor pack and PWM CONTROL.
My car is deawoo matiz year 2000 model,the fan is not working😢
Too bad...
answer some question.
Ask away...
Videos are good but I can't stand that computer voice - had to unsubscribe.
You should ask for a full refund
Fuckin-A Jose
This is the worst electronic testing equipment I have ever purchased in my entire professional life. There is no instruction available on how to use it, no warranty terms condition, absolutely nothing.
