18. Pace Lights aka Urban Joke

I am going to call this Urban Indian Joke

This needs some explanation about how lights are setup & controlled in the VW Virtus. It is important to understand this, before doing this adaptation.

Research credit – DV52 (Australia)

Introduction –

The 09-Cent. Elect. control module, or as it is also known, the Body Control module (BCM) is a central component in any car. But the BCM is particularly important in MQB platform vehicles. The importance of the BCM in the Virtus is underscored by the fact that it contains around 1550 adaptation channels. This is over 50% of all of the adaptation channels in the car. Buried deep within the large list of functions that the BCM manages is control of the car’s lights. In the Virtus, there are 646 (34 lights) adaptation channels devoted entirely to the way that the car’s external lights operate. Understanding how the BCM allocates resources to these adaptation channels enables VCDS cable users to customise the way that lights operate.

The Basics

Each light has 19 adaptation channels. These 19 channels are divided into groups of channels which define the overall parameters for the concerned bulb. These channels are –

1. Type_Of_Load – This defines the type of bulb. Could be incandescent, LED, etc.
2. Fehlerort_mittleres_Byte_DTC-DFCC_23 – this defines the position of the byte in the configuration
3. Lampendefektbit_Position – this defines the posiion of the bit in the above Byte

The remaining 16 channels are divided into 4 subsets – AB, CD, EF & GH. Each one of this subset contains the following adaptations- – Dimming – Decides how brightly or dimly the gven light will light up. 0 is off & 127 is max (for LED). Any value inbetween will make the light dimmer than full brightness.

• Dimming_Direction – This can be Minimize or Maximize. I haven’t fully understood this setting yet.
• Light_Function – This defines what the light will do. There are several possiblities. Understanding each one of them is WIP.

For this adaptation, we are only intersted in making the tail lights also blink along with the turn signal. The first thing we need to keep in mind is – in German Links means Left and Recht means Right. This will become important, as we need to be sure that we apply the correct adaptations to the correct side of the car. We could end up making the right taillight blink along with left turn signal. We definitely do not want that. We are going to configure the following channels – – Leuchte23SL HLC7 – Left side Outer Taillight

• Leuchte24SL HRA69 – Right side Outer Taillight
• Leuchte33AMBL 3C72 – Right side inner taillight (the section on the boot lid)
• Leuchte34AMBL 4C71 – Left side inner taillight (the section on the boot lid)

We can also make the Brake lights flash, by modifying these two channels – – Leuchte20BR LA70 – Rear left brake light

• Leuchte21BR RC8 – Rear right brake light

Adaptations – Change these values for the following parameters for each of the channels you want to make blink along with turn signal –

• Dimming_CD – Change to 127 for full brightness or a lesser value for partial brightness.
• Light_Function_C – Change to Blinken_rechts_Hellphase for right or Blinken_links_Hellphase for left side, if you want the tail light to blink in sync with the turn signal
• Light_Function_C – Change to Blinken_rechts_Dunkelphase for right or Blinken_links_Dunkelphase for left side, if you want the tail light to blink out of sync with the turn signal.
• Dimming_Direction_CD – Maximize

Considerations – – You have to disable rear DRL

• This will only work, as long as headlights are off.
• When headlights are switched on, these red lights will go to their default functionality of stay always on & working as taillights. A little more research & experimentation needed to get them to do this with headlights on.
• This adaptation will work with brake lights, even with headlights on. If brake pedal is pressed with turn signal on, the the light will stop blinking & come on steadily.

I reasearched & did this adaptation purely out of academic interest. I need to do a lot more research & experimentation. I will most likely go back to OE setup. The sheer number of possibilties is a bit overwhelming. But am making slow progress. Enclosing an excel spreadsheet with all the Leuchte channel mapping I have been able to identify so far. It is accurate to a great extent, but is not there 100% yet. Finally, here is a Video of this adaptation in action –

https://youtu.be/uCldyH-XWwc

As always, if you do this, it is on your own risk. I take no responsibilty for any malfunctions. Err on the side of caution. If in doubt, don’t do it. Ask & I will try to share as much as I have learnt & understood.

Here are my excel spreadsheet based on DV52’s original research paper. Attaching that as well. That one is pure gold. Guess the real experts always share. The man rocks Light Channels.xlsx
