What scan tool is recommended to reset CVT pressure after a fluid change? I have a foxwell that gives me CVT options but no option to reset pressures. 2019 Corolla .
Adding @Dan to the discussion
read that oil pressures need to be reset to 0

Last article on link. CVT oil replaced.
Did a fluid change, read that oil pressures need to be reset to 0 ,
I don't know what you're talking about.
First of all. The website and article is for a CH-R. You need to look up your model & year of Corolla
Here's what I see:
Reset memory calibration (which includes oil press) when the following parts are replaced:
Continuously variable transaxle assembly
ECM
Oil pressure sensor
Airbag sensor assembly (Yaw rate and acceleration sensor)
There's nothing about performing this procedure after changing CVT fluid.
What I do see, is
Perform ATF Thermal Degradation Estimate Reset after replacing the CVT fluid.
Correct procedure:
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
NOTICE:
Do not start the engine.
(d) Turn the Techstream on.
(e) Enter the following menus: Powertrain / Engine and ECT / Utility / ATF Thermal Degradation Estimate Reset.
Powertrain > Engine and ECT > UtilityTester Display
ATF Thermal Degradation Estimate Reset
Is that what you meant? Are you using a "Techstream"? Does your vehicle support it?
And what is this even for ... Turning on an idiot light on the dash?
I kno it was for a chr, was best “write up” I could find on the topic for you. The oil pressure needs calibrated on them after fluid change for smooth operations. Do the research yourself. I was looking for what scan tool to use cause my foxwell 680pro isn’t cuttin it. Autel requires a subscription. But anyways, look into the calibration yourself if your wanting reason behind it. Idk why it needs it but it does. Thanks for tryin to help.
I beg your pardon? Do the research myself? If I'm not mistaken , this is your vehicle. Thanks but I have enough problems of my own.
And to me it seems like you're creating unnecessary ones for yourself which I want no part of.
Can you elaborate why you want to do it?

I don't think this is the case. You just took some fluid out and put the same amount back.
Last article of link,, CVT oil replaced.
Most bi-directional scanners have a feature to reset the TCM to factory,
I'm unsure how common is to have an OEM level "fluid replacement" menu.
When you're buying a scanner, you can always email the manufacturer and ask.
I think you your best chances are with a Launch Diagun V or a ThinkTools Pro.
Sometimes, cheaper 4/full system scanners have "reset" features, but always verify if it has the option you need.
(Look in our scan tool recommendation thread)
Alternately you can try to find a shop that'll let you use their scan tool for a few minutes.
