This article focusing on how to read transmission temperature. OBDLink LX reader can read sensor information from the car, and stream it via bluetooth to whatever app you’re using on your phone.
First we show you something right here, check below picture.
Here is a little button, that’s allow you to pair with your phone. So one of the safety features of this is that it doesn’t continuously broadcast its location. It’s pressing this basically via bluetooth. That’s a safety feature so that presumably somebody with it intent can’t just go in there and basically hack into it and basically have access to your ECU. So you have to push that button in order for your phone to even see it.
Plug OBDLink LX into the OBD port in the car ( it’s one thing have to be sure that the car is off and the keys off out of the ignition)
Put the key in the ignition and set it on.
Go to your phone’s bluetooth setting, tap “scan”
You’ll find it’s not find OBDLink LX, the reason why it’s not find it is because that the OBDLink LX has a safety feature where it doesn’t broadcast its location continuously. So you have to hit that little button we showed you above.
Now re-scan and find the OBDLink LX. Click on it then tap “OK”
Pls note once you do that the OBDLink LX is paired with your phone, you don’t have to go through this process again. You have to do is have your bluetooth on and once you start whatever application you’re using say Torque Pro or active OBD whatever app you’re using to interface with OBDLink LX will automatically use that bluetooth link.
Now we need to get the application that we need to read the transmission temperature.
Go to the Play Store, input “active OBD for Subaru” on the search bar. Find it and install.
Once installed then open up the app.
Right now active OBD application is talking to OBDLink LX and it’s an OBDLink LX is connected directly to the ECU of the car and it’s given us sensor information the car doesn’t give you. The one we’re interested in right now is automatic CVT fluid temperature.
When you first start the car the CVT temperature will close to ambient temperature.
Let’s go ahead and take the car for a ride to see a sensor of how long it takes for the CVT fluid to get to temperature and what temperature is consider normal.
You can see the engine oil temperature is at 95 degrees Fahrenheit and the CVT oil temperature is starting at 59 degrees.
12 minutes later the engine oil reached the operating temperature and is hovering right around 198 to 203 degrees. Fahrenheit the CVT oil temperature now sits just above 150 degrees in the same span of time.
Above is all the step we showed. One final things if you already have the Torque Pro app, we suggest you uninstall the standalone app to prevent connection issues.
