GenIII Prius Custom PIDs for Torque app

Hello.

Is there a PID that let us see if engine coolant fan is on or off? I mean not the battery fan but the one in front of the radiator.

 

Good question, I'd actually like to know the same thing.

 

Hi priusito_de_mi_vida,

I have not looked into it but I believe it is at 7E0, 2139.

Here is my latest updates.

Hi guys,
Just started using torque, everything is working, but when I click on the link to the csv file it just brings me to this forum section OBDII Android App | PriusChat
any ideas why this would be?

Thanks!
Matt

 

Thanks! I ended up saving the spreadsheet I found in vincent's recent post, but glad its fixed for others.
I was able to find this post: Turning off the reverse beep on a 2012 Prius v

which explains exactly how to disable the reverse beep, thought it may be of use for someone else that's as clueless as me!

Hello. I can't see that one in the spreadsheet. Could you be more specific?
Thanks.

These are the ones I have in my screen:

 

Hello. I tried create a gauge with the data 2139, 7E0 and A as a equation, and the results were random numbers from the moment I started the car: 0, 29, 43, 0...

Of course, the engine was still cold. So the fan couldn't be working for sure.

It would be good a gauge who showed us the fan's RPM, or at least who let us know if the fan is on or off.

 

A is used as a dummy equation, not necessarily contains the actual data we want. useseawolf2000 meant to use Test PID function to get the full response, something like the screenshots in this link.

There is no PID for fan's RPM, only an OFF/ON status. If I'm not wrong, there are 5 data bytes.It is a 1 bit data so it could be in any of the 5 bytes. I suggest you take note of those 5 bytes, turn on A/C and see if any of the bit changes. Then, turn off A/C to confirm the same bit changes.

At what temp is the fan supposed to come on?

 

Are you talking about the radiator fan? I have read 194* F IIRC. If not, then its soon thereafter.

Matt

 

I find to do so a little bit difficult. Need some time to learn about it.

Thanks anyway.

 

Cool, thanks guys. Is it one speed or variable?

 

190 ºF = 88 ºC. I see that temperature in my scangauge everyday.
Isn't that a too low temperature for the fan to trigger?

There is a difference between prius and ct200h cooling: In prius I saw 93ºC frequently and in my new ct200h temperature never reaches 92ºC. I have grill blocked as well as the radiator.

 

hmm now you have me curious. I was fairly certain I read that happy coolant temps are between 154 and 194* F. Below that the ICE runs to raise temps, and above the fan runs to lower it. I could be totally wrong I suppose.

Markabele- Not sure about the speed, we just got our and here in NH its so cold that I haven't seen temps above 185 yet.. with a full block!

The fan does not only depend on engine coolant temperature, other factors such as air conditioning switch (on/off), air conditioning refrigerant pressure, engine speed, and vehicle speed signals also play a part.

Vincent

 

There are 2 cooling fan motors. The ECM switches the circuit between series and parallel by turning on or off the fan
relays in order to control the speed of the cooling fan motors in two steps.

Vincent- Your knowledge of this car astounds me! Where did you learn from?
