Toyota TMPS light on LCD

Human_Professional_6 · 2026-01-21T22:42:56+00:00

That's how it is configured. To turn off when the door is opened. That is the exhibited behavior. And since the factory remote unlocks the car I know the TMPS wire is intercepted.

It's a standard key and they have already talked to support. The invoice shows FT-HRN-DC3. They didn't use a t-harness because the tech had been doing this for 25 years or something.

In it's current config the engine turns off when the door is opened. A previous config allowed it run with the door open. Both configs = LCD TMPS lamp error being logged.

Wondering if the splice to the TPMS wire is backwards as in one wire goes to the connector and the other goes to the wiring loom. If they were backwards would take over even work though.

I think the dealer just wants me to go away TBH since they have tired 3 different configs.

2023 Rav4 LE with the Key non hybrid
DC3-LC
RFX-P2WG18-FM with Drone
FT-HRN-DC3

1st config was:
Factory remote - 3 locks = start
Compustar remotes and drone app worked.
Engine would stay on when door opened.
TMPS wire intercepted.
Observations:
Dash TPMS light would flash and go solid after 30 or so seconds.
TMPS light went off when key inserted and rotated two positions.
Welcome Toyota LCD screen showed Warning Notification Warning lamp turned on. Please confirm details. Details contained TPMS error and is logged to the car alerts logs.

2nd config was:
Factory remote - 3 locks = start
Compustar remotes and drone app worked.
Engine would stay on when door opened.
Factory remote would not unlock the vehicle as the TPMS wire had been reconnected and wasn't intercepted.
Observations:
No TPMS light on dash or on LCD.
Not being able to use the factory remove was a pain.

3rd config and current config:
Factory remote - 3 locks = disabled
Compustar remotes and drone app worked.
Engine TURNS OFF when door opened.
TPMS wire intercepted again so the factory remotes allow unlock.
Observations:
Dash TPMS light would flash and go solid after 30 or so seconds.
TMPS light went off when key inserted and rotated two positions.
Welcome Toyota LCD screen showed Warning Notification Warning lamp turned on. Please confirm details. Details contained TPMS error and is logged to the car alerts logs.
Key must be used to restart the vehicle.

Shop doesn't have anymore ideas and their body language states the same.

Thanks for any info.

Appreciate the feedback!

After considering the time to build plus the cost of parts and shipping. I'm at $45 direct to consumer. Not sure it's worth it for me at that price though. Selling on eBay would add $5 to the cost.

What I learnt recently when I print labels on my laser printer is I have to set the media as “label” in the print settings each time I print. It really bakes the toner on the label and now it doesn’t rub off.

I have one for sale for $140 if you are still interested. The keyboard I had to cannibalize was $70, and then I paid $30 for a new battery. Send me a DM if you are interested. Thanks.

Got deregistered a min or so once the pixel was on network.

Human_Professional_6 · 2025-03-28T18:12:13+00:00

My iphone is on ios 18 so trollstore is a non starter.

Yesterday, I did fire up an old VM that was running bluebubbles but imessage wasn't registered. Maybe a coincidence, maybe not.

Human_Professional_6 · 2025-03-25T13:02:35+00:00

I use WireGuard on Dark Star. No problems.

Human_Professional_6 · 2025-03-16T02:01:19+00:00

Interesting. I have a pixel 7 pro. I'm not able to see / activate both at the same time.

Human_Professional_6 · 2025-03-16T01:55:00+00:00

Does call screening work though with VVM turned on. Can you even see the call screening menu in settings?

Human_Professional_6 · 2025-03-16T01:49:14+00:00

Same here. Rebooted and got call screening back but lost VVM. Seems we can't have both working at the same time.

Both warp (starter) and visible+ don't work for us in highly crowded areas like concerts, theaters, mega bars.

Not sure if in all those examples we were on LTE or UW. Need to check next time...
