I did it! Keyless entry for your 124 made easy (and less than $100)! - Page 3 - PeachParts Mercedes-Benz Forum

Can any one please scan the REC-8 installation manual and user manual and email it to me?

I've purchased the REC-8 from this site but I've lost the manuals - I would like to transfer this system from my old car to my 95 C280.

Also, does any one know which wires I should tap into? I know those wires are in the trunk and I can test which ones I should tap into, however, if any one knows, it will save me quite a bit of time!

Thanks in advance.

i followed this procedure for a trunk installation. the wires in my w124 were all the same color code. don't know if it will be the same for your car.

I really need the programming manual for the REC-8 or REC-11. Can anyone please help by scanning just the programming pages and email them to me?

Thanks very much in advance!

Did the crutchfield keyless. Now when locking with the key and then unlocking with the remote, the alarm goes off when the door is opened. Doesn't happen open close with key, or open close with remote. What gives???

Same thing is happening to me.

This is true.

This step I have not yet achieved. I can not lock with the remote, and I can unlock only after locking with the key.

I reprogrammed the control unit from .8 to 3 sec. The DLSV does not have a black wire to connect to square connector but I believe it gets whatever it needs from the control unit. Correct me if I am wrong.

I am not connecting to convenience module yet. I got a taste of the comfort of the remote (unlocking doors) and I love it.

Why can't I lock using the remote? When I press lock on the remote, the control unit works but does not send a signal to the pump. Any ideas?

E. Lee, I'll scan the programming pages for the REC-11 tomorrow morning and send them to you

it works meaning you can hear the relays click? make sure you are supplying that +12V that goes to the pump side (i believe that's the green wire from the DLSV). if you are not getting the +12v there with the "lock" button then the external relays hooked up to the DLSV may not be connected properly...

jsmith, thanks for your prompt response.

Here's what's happening with doors initially unlocked:

Using key
Initially: +12V on green wire from DLSV.
Locking: 0V on green wire from DLSV (constant).
Unlocking: +12V on green wire from DLSV.

Using Remote
Initially: +12V on green wire from DLSV.
Locking: 0V on green wire from DLSV (temporarily w/o
engaging pump) and then returns to +12V.
Unlocking: +12V on green wire from DLSV.

Occasionally, I am able to use the remote successfully for only one lock/unlock cycle. Any suggestions are appreciated.

Thanks.

tkamiya, I will check the PULSE-ON you suggest. I believe that is feature #9 (Double Unlock Pulse) for my REC-11. Currently it is set to the default of OFF. I will try it tomorrow because I'm all "relayed" out for one day.

speedy300Dturbo has another thread(#45588) with a very helpful diagram:

This is how my relays are connected:

Is this right? It doesn't look the same. I'm planning on creating another relay setup as per speedy300Dturbo and trying it out. By the way, the two relays are identical except that one has 045 stamped on it and the other has 055. Are they really the same?
Thanks.

Sorry about the size of my image ("That's a HUGE bit**!!!").

jsmith · #42 09-26-2002, 09:01 PM

can't see the picture. anyhow, i think it's the pulse duration too. something called "double unlock pulse" doesn't sound right...

Speedy300dturbo had it right. Here's that animated explanation I referenced before:

click on the button that says "interfacing Mercedes vacuum doorlock"

This is the electrical schematic of what you are trying to do with those two relays (from the Crutchfield solution):

Sorry about the image guys. Still learning... Hopefully you can see this diagram:

Thanks for all your input.

jsmith · #44 09-27-2002, 11:07 AM

dacanes,

saw your pic once then it's not showing again. the only thing i noticed is that you didn't show the connections for the +12V and ground to the relays, i don't know if the DLSV handles that for you. the two 87's are connected to positive and negative respectively. the 85's and 86's are the triggers, they obviously need to be triggered independently...

HTH

SUCCESS AT LAST!!!!!!!!

Would you believe that the DLSV was wired incorrectly? I created a temporary relay connection as per speedy300Dturbo's diagram and it worked. I wonder if the other guys that had problems had the same DLSV hook up?

I then took it a step further and tapped into the convenience module to arm and disarm the alarm. That worked fine too

.

However, I am noticing something weird with the windows. When the windows are down and I press the lock button the car locks and the windows go up but only for 3 inches and then stop. Has anybody experienced this? Any ideas?

Special thanks to jsmith and tkamiya for their guidance when I was really close, and to speedy300Dturbo for the diagram that made it all possible. And to my mother, my father . . . . . .
