DIY ASR Defeat Switch - Page 2 - PeachParts Mercedes-Benz Forum

Vcci, thanks for the reply, I also mispoke (wrote) there are at least 3 versions of the ASR control module (N47-1) instead of just 2. I believe numbered; SK 16, LK55, and LKS511. I am also now doubting my previous theory with the brake switch, I believe this would throw the ABS into convulsions. So back to the drawing board for me. If someone could cross-reference what terminals #25, #35, and #37 are on the ASR control unit are used for on the 500E maybe I could find those on my ASR control unit. Thanks again.

sorry TIFOSI I wish I could help but as stated in my earlier post I am not very familiar with electronics and that why I had a friend do this for me. As I said before this has not interupted with any other component other than the ASR and I love this set up much more than the original set up.

I'll pose this question to anyone who might be able to help...
According to the RennTech directions posted, the RennTech module connects in between terminations #25, #35, and #37 on the ASR module. I'm assuming these are based upon an older version of the M-B ASR control module housing SK 16, or even the LK 55 type. My C36 has a LKS511 version of housing. I'm assuming again that the terminations must be different on these housing styles, as that the #25, #35, and #37 terminals on the diagram for the C36 are for; #25 - hydraulic pump runnnig check; #35 - left rear axle solenoid valve [hold]; #37 right front axle solenoid valve [release]. Best as I can tell adjusting, interupting, or anything else to any of these particular circuts wouldn't accomplish a damn thing other than screwing up the works. So if anyone has a diagram for an older version ASR control module [SK 16 or LK 55] and can find out what terminals #25, #35, and #37 are for, maybe we can reverse engineer our way into how RennTech is defeating ASR. Granted we won't know what exactly their defeat module is doing, I'll bet we can figure it out, and do the same thing for less than $1000.

To everyone waiting for the final result of my ASR defeat.
I finally completed my ASR defeat today when I had my friend install the switch, everythig works perfect, I can turn it on or off as i desire while driving or at anytime for that matter, I dont need to restart the car in order to reset the system. This has in no way effected my ABS system or anything other then my ASR. It works perfect and I'm 100% glad I did this. NO REGRETS.

For anyone interested in having it done, I have talked my friend in to doing this for others( for a small fee) so if you're interested drop me a line.
Thanks and Good Luck to all.

Some reasonably detailed instructions would be great...maybe a diagram or three?

vcci · #21 02-19-2003, 02:34 AM

In this post i tried to explain in great detail the process. In this post you will find a link to the diagram and instructions. Hope it helps.

Glen · #22 02-19-2003, 09:24 AM

Thanks...I mean, a diagram of the relay/circuit your friend made for the switch.

Lets see
Gas to Drive to Encino and back (2500 mi div. by 400mi/tank X 23gal tank x 1.75/gal) = ~$300(I hear gas is as high as $2.25 for Premium unleaded on the west coast

)
Payment of ticket(s) to State law enforcement agencies of Texas,New Mexico, Arizona, and California = $500
vcci's friend installing modified ASR switch= "X"$$
Not having to deal with the annoyance of undesired traction control.....PRICELESS!

Its looks like as sweet as the prospect of vcci's friends ASR defeat switch sounds its just cost prohibitive for me here in the Lone Star state. Gas/Hotel alone would dang near put one in my hands from bergwerks and I don't have to do all that driving to boot. Not that it wouldn't be one hell of a drive though. Maybe when gas goes back down to a respectable level (sub $1.60) I'll think about it some more. But for now, I'll just have to keep dreaming.

Lastly
Hey vcci, could you be a pal and take some pics of your setup. I think those of us who might be skillful enough to attempt this surgery, would be a lot more confident if we knew exactly what wires to splice into from a pictures perspective and where / how to then hook up the switch.

vcci · #24 02-19-2003, 02:00 PM

I would be glad to post some pictures but unfortunately pictures wont show much. I fact the relay box he put is behind the computer box and it is impossible to show anything in the picture.
The was placed next to the headlight switch. Here is a picture of the switch. sorry i couldnt be more help.

vcci · #25 02-19-2003, 02:01 PM

Here the ASR is turned off.

tom woolner · #26 02-20-2003, 01:14 AM

I'd love to come down from the Bay Area, get the Bergwerks first gear, then the ASR over-ride. Is your friend serious about doing for others?

Absolutely 100% and let me tell you, he is the best. I couldn't be happier with my defeat system. Drop me a line and we'll arrange something.

Is he interested in selling the diagram or the box itself...?

I'd have a bit of a problem driving to him......

Michael · #29 03-26-2003, 01:15 PM

I just defeated ASR in my 500E. What I did was to simply identify pins 25, 35, 37 (there are 2 sets of pins with each of these numbers, so I took my CAN apart & based upon color-coding was able to ID the correct pins; they're the set closer to the centerline of the car) on the bottom of the ASR module, then I took some postal tape (a bit thicker than your typical Scotch tape) and put a thin slice of tape over the pins. Thus, when you slide the module back in the connections are interrupted!

Just thought I'd share - done this way it's a 10 minute job and really easy!

Gonna go do some burnouts now...

Way to go.

Anyway to get a diagram of this Michael?

I've been avoiding messing with the idea of defeating the ASR but heck, if it's that easy who can resist. With a simple relay going off the wires you mention and the other side hooked up to a console switch you have a $30 (max) DIY ASR defeat.
