Hi nine8six,
no need to get out of the discussion. I'm still here.
You can't offend me, because i'm the guy who knows nothing and is always willing to learn something new. Just want to understand things. And if somebody needs infos i try to help the best i can. That's all.
I used the dictionary to translate the german term "Steuergerät" and the dictionary did translate it to ECU as Electronic Control Unit. Sorry for that.
And yes, i have often problems to translate everything i'm thinking about to an understandable english. Especially when it comes to technical terms. Trying to get better, but it's not always that easy. Sorry if there was something misleading.
If i'm talking about Lichtsteuergeräte (electronic control units for light) i'm talking about control unit from the same time. For example Mercedes used such control units, but the also use hardware relays for headlamp switching. And yes these are CAN-bus systems.
And no, my car has OEM-Litronics. So i don't need an upgrade. But my car has a problem with one Litronic headlamp that i couldn't solve. Changed the Litronic hid bulb, switched the ballast from one side to the other, checked all connections – but have the problem that the left bulb sometimes turns off if i drive over bumps. If i switch on the headlight again, the Litronic headlamp turns on immediately. So there must be a bad connection somewhere or maybe it's the light switch.
That was why i asked for relays and the light switch.
Regards from Germany,
Markus
