Subaru XV 2016 CVT Learning done by VXDIAG SSM3

Car model and year: Subaru XV 2016 with TR580 transmission

What I did:

Replace CVT fluid according to the repair manual.

Confusion:

I have drained only 5.5 liters of fluid (and filled with the exact amount). I’ve read somewhere that people drained 8-9 liters.

Drained hot, filled cold, but hot and cold fluid were mixed inside transmission when gears were shifted P-R-N-D and backwards, and after that added missing oil, shifted through all gears again and then drained all excess oil till it started dripping slowly through fill hole… So it should be fine based on repair manual.

Good to know:

Some models have the CVT fluid cooler which means the hold a lot more fluid. It’s a reasonably serious process to change CVT fluid. Got to get the temperature right to get the level right.

Finally, got the VXDIAG and hook it up!

There is a very specific temp the fluid need to be checked at. Not just hot or cold. I have VXDIAG SUBARU SSM-III SSM3 SSM4 Diagnostic Tool to track the temp, but they are making nuclear science of something fairly simple…
And yet, engine oil change is done without temperature checking.

Well I am pretty sure that it has some quantity tolerance, as there is no way to measure quantity with 100% precision without using the machine for replacing fluid (there is 10°C difference between lowest and highest fluid temp when replacing, so that is the first thing that change quantity)…

But anyway, I have replaced fluid, everything works fine.

How to use VXDIAG Subaru SSM3 EDR Function?

The EDR function may be accessed through the Airbag Systems portal of the Subaru Select Monitor (SSM III or SSM4).

EDR:

Some Subaru are equipped with an event data recorder (EDR).  The main purpose of an EDR is to record, in certain crash or near crash-like situations such as an airbag deployment or hitting a road obstacle, data that will assist in the understanding how a vehicle’s systems performed.  The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less.

These data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.

To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.

Subaru SSM3 Record Event Data (EDR):

Go to the Main Menu, selecting Each System Check and then Airbag System. Once there, Event Record Data may be selected from the options listed.  Once this area is selected, an Important Noticescreen will appear with the following message:

You will then be asked to check a box indicating that you are aware of and in compliance with the areas outlined in the Important Notice message.  Once the box is checked, the “YES” button will become available to select so you can proceed with viewing any data that may have been collected by the EDR.

If you have reached this area in error or have not received proper legal authorization to view any data in the EDR, simply press “NO” to return to the Airbag System menu.

Example: 

Test VXDIAG Subaru SSM3 (not SSM4) on Windows 7 Pro.

Select Airbag System-> Event Record Data

Stored Data from Code:

Multiple module data gathering. It worked for some modules but not all.

Example when connected to HVAC + Airbag shown below. Also shown is all that is shown under “Current Data Display & Save” for the airbag module.. So I assume you get more data with an EDR report as this data display doesn’t even show vehicle speed. I wasn’t able to find a way to select only certain data points from each module to allow for faster sampling. Data can be recorded and saved, then reviewed just as it appears below (and as it appeared when gathering the data real-time).

How to do Subaru Force Sensor Calibration with SSM3

Why require a Force Sensor Calibration?
After EPB actuator assembly installation is complete (address DTC C0251), the Force Sensor Calibration Mode must be performed with the Subaru Select Monitor following the procedure.
Caution:
Subaru Select Monitor (SSM-III) is required for the Force Sensor Calibration Mode.
Make sure to perform this procedure with the vehicle parked in a horizontal place and to use wheel chocks.

Note:
When the following work is performed, use this function to perform calibration of force sensor in the parking brake actuator.
-Removing the parking brake assembly
-Replacing the electronic parking brake control module
-Adjusting the shoe clearance
After replacing the electronic parking brake control module, if the calibration of the force sensor has not yet been performed, the brake warning light will blink and "Force Sensor Line (abnormal) DTC will be detected.
1). Park the vehicle in a horizontal place using wheel chocks.
2). Connect the VXDIAG Subaru SSM3 scanner
3). On Main Menu display, select Each System Check
4). On System Selection Menu display, select Brake Control System
5). Click the OK button after Parking Brake System is displayed
6). On Maintenance Operation Mode display, select Force Sensor Calibration Mode
7). The confirmation screen of vehicle parking condition and wheel chocks usage is displayed. Confirm the parking condition and wheel chocks,. and click the YES button;
8). A message indicating the calibration mode in progress is displayed on the screen, and the Force Sensor Calibration Mode begins.
9). The message "Force sensor calibration done"
Turn ignition switch OFF is displayed on the screen.
Turn OFF ignition to end the calibration mode.
