DIY ASR Defeat Switch - Page 6 - PeachParts Mercedes-Benz Forum

I tried to diagram out each of your tests and think maybe this might work, so if you would give this a try:

1. Wire from supply (+) to pin 2
2. Pin 3 to relay (+)
3. Ground (supply (-)) to pin 1
4. Relay (-) to supply (-)

This might get it all relay, LED switch, etc, hope this works, good luck!

I modified your photo, I think it's something like this...

TIFOSI · #78 07-06-2003, 10:56 PM

Any updates?? Have you finished your custom ASR Defeat switch yet? Let us know.

Michael · #79 07-07-2003, 07:46 AM

Sorry for the delayed update, but I've been busy

Plan is to try this newest version of the circuit; if it doesn't work, then I'm simply gonna run power to pin 3 and ground pin 2 - switch works perfectly in this arrangement. However, no light in his configuration, so we'll keep plugging [:-)

I have a detailed skematic of my C36's, and the three pins (25, 35, 37)referenced by both RennTech and all of those who've defeated ASR, make NO sense. But that is on my "newer/different" ASR box... I assume? Even so does anyone know what the 3 pins (25, 35, 37) reference on the 500E ASR box? If so I can try and find the corresponding functional pins on mine, then share it with the world - FOR FREE!!! I JUST WANT TO HAVE CONTROL OF MY DAMN CAR!!! Sorry for the rant and rave - I just really want to lose the "nanny". As always any help is greatly appreciated...

TIFOSI

please share the info if you have find a way to completely diable the ASR.
I also have 97 C36 and been researching for this with no luck until I came across this thread...

sound promising....

Perhaps after you found the solution you can create a new thread

TIA.

Regardz,

Works like a charm. No illumination of the switch, but I can live without it. And you definitely know when it's engaged-the ASR light comes on in the the instrument cluster, and the snow chain switch light comes on. Oh, and the rear tires melt...

Can't wait to try it out on VIR- anyone going 8/2-3?

Micheal looks real cool. Can you takes some pics or sctech out a diagram for me if you can. Teh switch referring too is the snow chain is it not. What type of relay. You know thye theft deterrant light we have. Cna't we remove that install another toggle switch that would work as a realy relay. I mean whgere do you have your little realy box located with the wires running off them. Pls get back to me .

Thanks guido!

Parts list:
1.) Rear dome light on/off switch (from a 500E)
2.) ASR "off" switch (W140 S500)
3.) 6 wire bundle - approx 4' of cabling (I used a cable intended for trailer lights - purchased at JC Whitney; I have enough for 3-4 more switches) - this runs out the side of the CAN box (I drilled a hole, then RTV'd it to seal it once the wires were all connected)
4.) 2 wire bundle - for power & ground to the circuit - I grabbed power from the lighter circuit, and ground was connected to that same circuit)
5.) 3 pole relay & socket - I used a 4 pole, and simply ignored one of them; it's installed in the area behind the passenger-side airbag, accessed from below
6.) Butt connectors - used to cut into the factory harness, inside the CAN box
7.) 3 amp fuses & holders (I fused both power & ground, just for giggles)

As to where one would locate the switch, in order to put it up above the HVAC controls as you suggest, Guido, then I'd think additionally you'll need to purchase the socket that the light switch would normally plug into, as that is what will hold the switch in place. In my case, the switch simply snapped into place as the fader switch did...there are small plastic spring clips that are part of the console wood piece.

Good luck, and if anyone wants me to pull this all together as a package, let me know (since I already own some of the extra parts, especially the cabling which was not cheap)

How much for a pre-assy kit

Chris W. · #85 08-04-2003, 12:51 PM

If you put this kit together with "most excellent" instructions, I'm all over it.

I think I can do 5-6 kits - I'll call MBZ & get all the prices together & let you guys know

TIFOSI · #87 08-04-2003, 05:17 PM

Michael, I'm glad to hear your switch is working well, too bad about the LED though. I wanted to put my question out there again as far as newer models go (C36's) the 3 pins/circuts that are being switched do not match up with the pin/circut numbers for the C36 ASR module. Does anyone know for sure what the 3 pins on the E500 ASR module do? Anyone??? I'd like to cross reference the E500 system to the C36 system and build my own defeat switch.

So my question, or challenge if you like, would be for someone to find out the true purpose/name/label of the 3 circuts used on the E500's. I sure someone out there can find out what exactly the pins are labeled and used for!! If some could find out what they are I'd gladly owe you a beer, or several! Thanks again... - NL

ItalianBenz · #88 08-04-2003, 09:57 PM

Mike count me in. But let me know. The MB part no#. I'll get those my self to save on the cost. To you and me.

thanks.
Guido

Michael · #89 08-06-2003, 07:49 AM

I don't have the part numbers handy, and the folks at the local dealership aren't fond of giving out P/Ns without their purchase. Guido, you work at a dealership, can you hit up your parts dept for the numbers?

Thanks in advance

Michael, If the cost is not too high, I'm in too..........Vince
