Daytime running lamps

In the Canadian models, when the ignition is turned on, the exterior park lamps come on. When placed in a forward or reverse gear the low beams come on.

Is there any way to defeat this without giving a malfunction indication? Perhaps by interrupting the ignition unit at the light switch?

I would like to know how to get DRL function on mine. Is there a relay I can install or is this function programmed in the computer.

I believe it's a function of the headlight switch on these cars, you'd need the switch out of a non-DRL car to defeat. I have a car without DRL that I'd like to add DRL to...we could trade switches if your '02 switch is the same as my '99. Where are you located?

I read it on ML class, but likely the software is shared on most of the models.
What you need to do is getting a computer that can read car programs and reset it from Canada to USA version.

Forget the mumbo jumbo-find someone with DAS Xentry and have him recode the front SAM----however then you do realize that you will be in violation of Canadian Law,therefore if Dudley Doright needs tickets that month you may get one!!

Funny you say that. I build Police cars for a living for my municipality, DRL delete is one of the options ordered (chargers)

I'm. There are no mandatory regular safety inspections here.

If its relative to the switch itself, I have no qualms about opening the switch. But I would much rather try the software approach rather than hack wire.

Even if you find the wire, it will trigger errors, so you have to do it the right way.
I wish that was as easy as on my Ford truck, where I simply unplug the relay.

Is this the case with the pre-facelift W210's as well? I'd read (can't remember where, may have been another forum) that this was a function of the headlight switch on these cars.

Plutoe

Don't be stupid and screw around with the switch, that is the same idiot that recommends removing fan blades to cool the engine---simply hook up to DAS and review the SAM coding!!

DAS: elaborate please.

IanB

Fired up the DAS tonight, and went through the following menus:

XENTRY ->DAS
-control units
-body
-SAM-signal acquisition & actuation module
HHTWIN
-actuations

And these are the options available in the attached pic. I had a hunt around and was not able to find where I could reprogram the SAM so the car knows it is in Canada, and the DRL's are to be active. Any pointers?

DAS = Diagnostic Assistance System used by MB dealers

I assume this is proprietary software?

And I can't possibly download it from the Internet?
Can I get the parts(?) myself?

Plutoe likely overdose again, so good luck waiting for him making sense.
You guys need to learn how to use google.
I found info that the option resets in AAM
Here is another topic. Since SD computers are rare and owners who know how to operate them even rarer, you have to collect bits of information and give it a try.
