718s Is there any way to turn on the 4 point LED and headlights together?

Jonathan_987

Code the following two values in the front BCM from nein/no to ja/yes and let us know if it worked:

I turned on both values ​​and they are the same

Here is the coding with my x431 to keep the 4 point LEDs on even when the headlights are on. if you are using a PIWIS you will have to translate them to German to try to find them.

Rear-End Electronics: Exterior Lighting: Exterior Lights, DD as a marker light = YES {Default: No}

Rear-End Electronics: Exterior lighting parameters: Dimming value for DD lights as marker light = 100 {Default: 6}

Anyone know what the coding that Jonathan_987 provided does?

Edit: I believe the coding provided by Jonathan_987 is to illuminate the instrument gauges even when the headlights are off (aka Scandinavian DRLs).

No, it should mean that the daytime running lights are also active when the lights are switched on (at night, etc.). You write something similar, but refer to the rear module. If possible, @blacks should also try coding the rear module accordingly.

I am pretty sure the coding you provided turns on the taillights, light license lights, front side markers and the gauges including the needles even when the lights are off. I don't have a PIWIS so I don't know for sure but the google translate of the codes look similar to the codes on my x431.

I am also pretty sure this coding has no effect on the 4 point leds which is what I believe was what @blacks was looking for.

Ah neat idea. I will add it to my list of things to look into when I pickup the car project again.

Based on my past experiences with these sorts of cameras, the camera is always running on a dedicated video input to the dashboard screen. The input is on a video circuit which overlays any other signal on the interior screen whenever the vehicle is put into reverse.

Usually telling the car it is in reverse enables the camera. Both the camera and interior screen have no 'boot time', which is why you can turn the car on and throw it into reverse and always get the camera even if the PCM is still booting up.

All that to say - there may just be a simple wire pair that you need to shunt to ground to allow the backup camera to override anything on the PCM screen.

@edub Just throwing it out there, but I don't think the suggested OEM backup camera would be a good choice for a rear facing road/track camera, it is low quality and points more to the ground then the area you would want to see such as approaching cars.

This appears to be a better approach:

I did not like the fact that the rear camera on my 718 didn't turn off until I reached 16 kph (or 10 mph) so I lowered it on my car to 5 kph (or 3.1 mph) using the codes below. You could try increasing the speeds in these codes so that the rear camera stays on. I have no idea if this would accomplish what you are trying to do.


Park Assist: Speed thresholds-System switch-off speed = 5 {Default: 16}

Park Assist: Speed thresholds-System switch-off speed display readiness = 5 {Default: 16}

Park Assist: ECU coding data-OPS switch-off speed threshold = 5 {Default: 16}

This thread has been a big help for coding features on my cars. Hopefully the following is helpful for some, as I didn't see it clearly described above (apologies if I missed it).

Disable and enable the daytime running lights (DRLs) via the PCM.

1. Enable the DRL lights menu item in the PCM Settings menus:

In engineering mode:
Kombiinstrument --> Coding programming --> Manual coding without coding rules --> Bordcomputer Menukonfiguration --> Bordcomputer Menukonfiguration: Bordcomputer Menuekonfiguration Byte1 Tagfahrlicht (changed from 'nicht aktiv' to 'aktiv')




After this change, you should see the checkbox menu item in your Settings --> Exterior Lights. Checking it or unchecking will not yet do anything.

2. Change the front end electronics module to allow the DRLs to be turned on or off.

BCM vorne --> Coding programming --> Manual coding without coding rules --> Coding value --> [change the two values identified in the image below] - Coding value: Aussenbeleuchtung TFL Vorschrift from 'ja' to 'nein' and Coding value: Aussenbeleuchtung TFL ueber PCM Kombi aktivierbar from 'nein' to 'ja'




The 'Vorschrift' setting change indicates that the DRLs are not required by regulations. If this isn't changed, this rule would likely prevent any of the other settings from turning the DRLs on or off since the car thinks they are required to be on by law/regulation.
The PCM Kombi setting makes the DRL menu configuration on/off setting activated in step 1 above become actually active (instead of just being a dummy menu setting with no enabling rule).

After setting these, I can turn my DRLs on and off just by checking and unchecking the setting under the Exterior Lights menu.

Great find. Someone with 718 should test this 👍

Ken718B

Confirmed daytime running lights menu works on my 718

Good job with the user guide on 718 forum 👍

Thank you. I have done almost everything I set out to do and even somethings that I did not know I wanted to do. The only thing that I have not been able to figure out is how to change the coding to allow the windows to be completely down when I put the top goes down.

I don’t know if this is hardcoded somewhere. You have to look at the wiring diagram and see which modules interact with each other. For example the door sensor, door module and BCM’s
