Re:Gen.4 instrument panel lights.

The sensor on dash consist of two seperate sensors in one. It seems
One managing headlights and one the dash lights.

I will post a pic tomorrow of what i did

I put tape partly over the sensor. You will need to play with where you need to put tape.

So my car is right hand drive...

So when lights are set to auto:
1 Driving lights will always be on because you cover the section on main lights. Car see ooo it is dark. Lights are always on.

2 The dashlight side of sensor is not covered and car see aaahhh the sun is shining. Keep dask lights bright. In the night the sensor see it is dark and auto dim it accordingly the darker it gets.

So I basically deactivated headlight sensor for daily drive.

Crazy. Not at all !! It is actually working. Really nice.

The part i like is when having lights set to auto i dont have to switch lights on and off all the time. Just put on auto, i have "daylight" driving lights (headlights) and dash lights is nice an bright

In the righthand drive the split light sensor is on left side. Dont know lefthand drive and if switched also changed sides

When you driving under bridge the dashlights dim for moment that sensor see shade (darkness) but pop back right back after 2 seconds.

NOTE
When testing.
Park vehicle outside garage in sun but close enough to see vehicle lights inside garage lighting up garage if they on.
Then set lights to Auto.
Start wit your hand completely cover sensor and you will see effect. Main lights on but dash will be dimmed.

The start playing with tape to determine where to put it so lights is on but dash lights is staying bright take a little time. I started with a little sqaure cardboard till i found the position where driving lights are on, and dash light brite in daylights.

Also remember there is delay on sensors so take your your time. The moment you put tape over section of sensors then it take 1-3 ,seconds for dashlights to adjust. This is not instantanious.

Red area is illustrating insulation tape you use to wrap wires. Work best for me as tape nice and sticky in final position



So my jimny alway on auto, i dont have to switch main lights on off. It is a set and forget setting. Moment i start the headlight see darkness under sensor, and main light are on. Dash light sensor see sunshine and never dim it during the day. (Unless you driving into under cover parking are then dash lights will start to dim)


I think you have to play to find out what area to cover and what to leave open.
My findings was more or less 3/4 covered and 1/4 open. That was my sweet spot.

Possible you might need to use other combinations to find your spot managing main lights ( must be covered,) and section that must be kept open so during daylight the dash lights do not dim

Work for me perfectly.

Just a heads up, you need to specify the country you are in when referring to the dash sunlight sensor and dashboard lighting settings as it does differ from county to country.

lookonimages and I are both in South Africa. The Phillipines appear to have similarly specced vehicles to us.

Here it is. The gap is very small that is left open for dash lights to stay bright.
Like i say. Lights is on AUTO.
Driving lights always on. And dask lights not dimmed.

Here is photo to show.
Lights Auto.
In full sunshine.
You will see headlights on. See back of garage.
The dash lights and radio not dimmed.



Then another pic where I completely block light sensor.
Lights Auto.
In full sunshine.
You will see headlights on. See back of garage.
The dash lights and radio now dimmed.
This will normally happen when sun goes down and it become dark. The dash lights dimmed.



Please note once i remove hand over sensor it takes a second or two before radio and dash lights to become bright again. Please take this into consideration when you play with closing off the light sensor.

It really is very small section that need to be kept open.
I previously said 1/4 open. But it is really 1 - 2mm that need to be open

----

Brightness of display, radio.
Lights on auto
Part of sensor not close.
Nice and bright.



Sensor completely blocked.
Then only radio dim.



What a pleasure to drive with headlights on during day (simulating daylight drivers lights) and you still can see dash and radio clearly in sunshine.

Hope it help a fellow south african where we do not have daylight driving lights as part of package.


At night time where you dont want the auto, then put it on "ON" and you in full control.

I drive 95% in daylight. And it is working perfect for my requirements.

Thanks for mentioning that Martin!
Some of the South African cars may be Australian spec due to shipments dirverted there by Covid bans in Aus.
My Jimny had the sensor on the drivers side of the dash, however a faulty circuit board after the sensor killed the dash lighting in daylight (Service Report:  "only Fault Code was in BCM BC150A, Sunload Sensor High, Sensor is fine" this was given to Martin). 

I now have a C30 and the dashboard lighting problem has followed me!  This time dash/speedo/instrument lighting is just not available in daytime (the manual), and thats down to Bosch, who do some of the Volvo software.  I have a dealer in Wales checking to see if this can be changed in RHD cars. 
cheers, all, George
