Light sensor but no auto lights - Toyota Yaris Forums

Vins213 · 12-07-2021, 03:43 AM

Hello there! Cit.

I have the Toyota Yaris Hybrid Active 2018 with light sensor under the windscreen, but I don't have the 'Auto' mode in lights lever (I have the Auto High Beam). If I buy the light switch lever with 'Auto', will it works? I also bought the Cruise Control lever and installed it, the car doesn't have that OEM, but with 20€ now it works without problems!

Thanks :)

It's going to depend on whether your body control module supports automatic headlights. The sensor goes to the body control module as does the auto switch wiring on the headlight stalk. If your car has all that wiring and the body control module supports auto headlights, then I reckon you'd be in luck.

How do I know? Is there any way to see the wiring? Thanks!

Option 1: Hook the switch up and see if it works. Option 2: Compare the part numbers of body control modules to see if they differ and get the wiring diagrams to start tracing and testing the circuits

Vins213 · 12-07-2021, 09:12 AM

option 1 is not possible because I don't have the switch now
for option 2 how do i check part numbers and control modules?

Do you have a VIN number for a car with the auto headlights? - toyodiy.com

Nope :(

What's the part number of the light sensor/wiring diagrams? That's my Toyota:

I have all the codes that are on the Yaris Style, right? So...the idea can works!

PS: I don't have the mirror-automatic retractable, so I have the cable drive but not the motordrive or the button inside the car...

Vins213 · 12-09-2021, 10:27 AM

And also my Yaris Active has:
84140 SWITCH ASSY, HEADLAMP DIMMER

84140-0D270

84140-0D300

The other Yaris Style has:
84140 SWITCH ASSY, HEADLAMP DIMMER

84140-0D300

84140-0D310
LIGHT CONTROL SYSTEM-WITH(*ALC & AUTO OFF & FOLLOW ME HOME)

Well.....that's good

Vins213 · 12-16-2021, 09:34 AM

It works perfectly!

Vins213 · 07-26-2022, 11:32 AM

I received two pm but I don't know if the system sent them correctly....so:

the item to buy is this 84140-0D310
like here: https://www.autodemolizionegualtieri...view&id=179012

with the 'AUTO' signature on the light switcher

Second: follow the steps in this video
https://www.youtube.com/watch?v=MugS...ALP2Xw&index=5

if doesn't work, the car doesn't have the correct wiring, my Yaris is an 'Active' one, but now is like a 'Trend' one with cruise control, auto lights and auto folding mirrors installed :D

Hello,can you please tell me what part number you bought for the cruise control ? thanks

spanishyarisdriver · 05-10-2023, 04:03 PM

Hey vins. I have a 2018 hybrid feel in Spain that has auto high beams but not auto lights. You think I could do the same? Also, what did you use to get the auto folding mirrors. I’d be interested in that too. Thanks.
