Here comes the unbaised review of the vxdiag vcx se subaru diagnostic scanner.

‘I purchased this unit to do one thing, register my H001SAL002 remote start installation on a 2018 Outback. It will only register via SSM3 and only under the Denso option when prompted, SSM4 will not present you the option to register the OEM remote start unit. After 2 weeks of messing around, I finally got everything to work correctly and got the remote starter activated. The cost was worth every penny, some mouthbreathing small brain tech wasn’t in my wife’s car butchering anything and now I have to ability to directly interact with the ECU as I should be.

When everything works correctly, it does exactly what it needs to do, one star lost for having to mess around with the software, VXdiag really needs to figure out a better process to make everything work correctly without tricks.

Here are some steps to get everything working the first time:

1. Use a laptop that you don’t care if you have to reset it, in fact I encourage starting with a fresh flash, DO NOT use your daily tuning laptop! You will be disappointed if you do bad things to your computer and have to start over, you’ve been warned.

2. DISABLE WINDOWS DEFENDER!!! If you can’t do this, stop now and return this unit, DO NOT PROCEED. If you have a third party antivirus, turn it off. You only get one shot to do this right, DO NOT reboot the computer unless you have an exception setup for the patch.

3. Set your system clock to 1-1-2018, if you fail to do this, SSM4 will not install. If you change the clock later, SSM4 will lock you out and you have to reflash the system. If you dont do this, SSM4 wont even install and you need SSM4.

4. Only use the 2020.7 ISO, do not try to use the older 2018 build, it will work but will not work right.

5. ONLY install the programs from the Launcher, work from the bottom up

6. The Subaru.exe patch must be placed in and executed from c:\. If your system deletes it, you failed to follow instructions and should stop.

7. Install VXManager last, start it first.

8. Connect to the OBD interface, make sure the license updates before starting SSM3. Update SSM3 if needed before launching

9. Run Subaru SSM3 from the launcher only, it will not recognize the interface if you try to start it externally.

10. Try to scan the vehicle first, if you cant connect you wont be able to do anything else. If you made it this far you will be able to figure it out from here. Have fun.’

SSM4 can connect to Outback/Legacy 2020+ new system.



An 8-digit “Authentication Key” supplied by SBR will be a required input when working with SSM4.  Unlike the previous system where Teaching Codes have been unchanged, the new Authentication Key will change approximately every 6 months.   The new vehicles utilize an Immobilizer Type “G” or “H” system depending on model:

• G:  Vehicles with a turn key ignition switch

• H:  Keyless Access with Push-Button Start.

Here is the procedure to perform immobilizer-related repairs on the all-new 2020-2021 year Subaru Legacy and Outback.

Procedure:
Connect SSM4 device to the vehicle and start SSM4 application, from the Main Menu, select Immobilizer etc. registration, select the Vehicle then Immobilizer Type and Confirmed.

When the vehicle utilizes either a G or H -Type system, an Authentication Key is required to perform any of the immobilizer-related functions listed in the menu shown below.

Currently, for all other models, the immobilizer registration process is unchanged.

For 2020MY Legacy and Outback with a G or H -Type system, the Server Connection screen shown below will be displayed. Input the current Authentication Key and select “Connection”.

IMPORTANT NOTE:  

As of June 30th, 2022, the Authentication Key has been revised to XFT7DWTH.

Great scanner for the money! This small size scanner packs a punch. It’s easy to use. You can’t go wrong with this one.
