In addition to the bioaerosol risk, ultrasonic humidifiers aerosolize minerals found in tap water. This transforms “hard water” into ultrafine particles that create a white film on surfaces and, when inhaled, can lead to respiratory distress. Use RO water, or better yet, distilled water, to minimize this.

@SawyerMerritt https://t.co/yZBYkFaoTZ - thanks!

@SawyerMerritt But does it have HW4.555? 😂

[E @Eric5un]

@evsmiles For your Highland 3 - Did the 2026 update split the VCFront Controller module (under the Low Voltage settings under service mode) into “2” controllers?

[E @Eric5un]

@greentheonly @DirtyTesLa @NotATeslaApp

Looks like the Front Body Controller (VCFront) for the refreshed Juniper Model Y also been revised for the HW4.5 computer. Couldn’t access the part label but the ID label notes “AP45”.

#HW4point5 #AI4point5

Additionally, the VCFront module in service mode has been split into two (virtually?) — “VCFront”which routes to the PCS and “VCBATT” which routes to the LV Battery. On factory software 2025.44.200. Not sure if this setup is consistent with all Junipers or specific to HW4.5, but VCFront is just one module on legacy Y’s.

Will getting access to Service Mode + reveal any new bits and bobs software-wise, @TESLA_winston? For some reason when I put the vehicle’s VIN into the Tesla EPC it returns a “Catalog not available for this VIN” message.

Hardware 4.5? @greentheonly @DirtyTesLa @NotATeslaApp

“AP45” + part # 2261336-02-A

Picked up a Fremont-built 2026 Tesla Y today (one of the last w/ Autopilot), mfg Jan 22. Includes new front camera housing + 16” screen, but no repeater/rear camera washers

#HW45 #AI45

[E @Eric5un]

@greentheonly @cant_pickaname My understanding is the 16” screen is easy plug and play with highland 3’s and juniper Y’s

Put the new Model Y Performance screen in my Model 3. Font size does appear slightly smaller but besides that just plug and play.

Considering how easy this was, can only assume it will be available as a retrofit

[Todd DeRego @toddderego]

Is this @telsa "Hardware 4.5" FSD computer new? I don't remember seeing it before @greentheonly Do you know anything about this? @SawyerMerritt @niccruzpatane

[E @Eric5un]

@TZingGP @JasonFranciosa @greentheonly @DirtyTesLa @NotATeslaApp The black border now extends along the bottom side of the camera housing

[E @Eric5un]

@cant_pickaname @greentheonly @DirtyTesLa @NotATeslaApp It’s an easy retrofit if it ever comes to that

[E @Eric5un]

@cant_pickaname @greentheonly @DirtyTesLa @NotATeslaApp Likely old screen if grey headliner

@bradhs @greentheonly @DirtyTesLa @NotATeslaApp What firmware were you on prior?

[E @Eric5un]

@bradhs @greentheonly @DirtyTesLa @NotATeslaApp I believe S2 indicates a replacement/service part, whereas O2 indicates factory installed. Should still be HW4.5 though?

[E @Eric5un]

@greentheonly looks like there’s two VCFronts (or at least a virtual device)? In service mode, VCFront is split in two with one running to LV battery, the other to PCS. Wasn’t present on legacy Y, not sure if Juniper-specific or more recent update.

[E @Eric5un]

@mweinbach @JasonFranciosa @greentheonly @DirtyTesLa @NotATeslaApp Interesting. I ran my VIN through Tesla service portal and it didn’t register

[E @Eric5un]

@KBTesla1 @greentheonly @DirtyTesLa @NotATeslaApp Y Premium AWD

[E @Eric5un]

@mweinbach @greentheonly @DirtyTesLa @NotATeslaApp Nothing different for autopilot menus. I do see the VCfront is split into two—one for LV battery and another for the PCS in service mode. Not sure if this is relevant in all Junipers, I am comparing against a legacy Y

[E @Eric5un]

@JasonFranciosa @greentheonly @DirtyTesLa @NotATeslaApp It’s quite easy—pull down the upper carpet liner (it houses a light and vents) below the glovebox. It’s attached by a push clip towards the door and two magnets,no tools necessary. Just be careful not to pull too quickly towards the left where the speaker line is connected
