w124 scorpion alarm and central locking info.

[gorselands]

Flat battery set off the alarm. Had to disconnect the siren. Central locking now not working as alarm and C/L are connected. Scorpion alarms taken over last year by Electro Systems Ltd. Spoke to Tony who originally worked for Scorpion.

The alarm ECU is located under the dash - driver's side. It needs to be removed (this immobilises the car) and sent back to Electro Systems for reprogramming £32.89 inc.

Leaves some questions: How long should the alarm remain unaffected with the battery disconnected? How are the alarm remotes reprogrammed to the new ECU? Anyone with a similar experience?

1993 220 CE

You have me lost here (easy)

First of all, your battery went flat or near flat (for whatever reason), and the voltage drop set off your alarm. Am I with you so far. This is normal, and it's imobiliser enacts.

You then disconnect the siren, because the noise was a nuesense. Am i still with you.

After that you speak of removing the alarm(ecu part) and of sending it off for reprogramming. Why? Do you not have a fob for the alarm?

Can you tell me the scorpion # (ie 918

 

[gorselands]

Thanks Pascal, sorry for not getting back sooner had to go out and sorry that the message was confusing.

Yes the voltage drop probably set off the alarm and the fob had no effect, nor the spare one. Both had been working up till then so I think I can rule them out as being the problem. Eventually I had to disconect the siren.

I spoke with Tony, formally with Scorpion, and he said that I would need to send the alarm off to them for reprogramming as it would have 'lost its memory'.

The alarm (ecu) is still in the car, somewhere under the dasboard?? and the battery is on charge. The reason the battery went flat, by the way is because the car has been off the road for seven weeks while MB got me a new ignition barrel from Germany. I only had it fitted by an auto locksmith today and the alarm went off when I tried to restart the car.

I dont know the # of the alarm but the key is seperate from the fob and there are two wires to the siren. I can understand a voltage drop setting off the alarm, what I don't understand is why it should need to be reprogrammed.

Sounds like crap to me.

It has happened me before; charge battery, turn off with fob. What is the number of the alarm.

This same Tony has told someone else that they need to send alarm back to get a new fob, when the user manual says they can programme a new one from seriel no., plus proof of ownership.

Have most scorpion diagrams.

Hi Pascal _ thanks again. Battery on charge and will try reset again. The only number I can see at the moment is on the RED siren - 334, but I believe it could be a 918. Although the car came with fsh + all the keys and fobs, there is nothing re the alarm except the silver sticker in the window to say it is MB fitted.

 

[pascal]

I can Email you the owners manual, if u find the number

 

[gorselands]

Hi Pascal, Have done what you suggested and alarm and central locking is now working. From what I have found out the Scorpion alarm No. is 918. I would certainly appreciate a copy of the owner's manual. email: xxx@xxxxxxxx.com

Thanks again for you help

 

[pascal]

Just sent to you Mike, and disguised you Email.

I would make a complaint to Electro Systems Ltd.

This line: 'send the alarm off to them for reprogramming', from them, sounds ridiculous from where I'm standing.

Pascal

Glad everything is working fine. Just goes to show. No cost solutions are sweet. EH?

 

[gorselands]

Thanks again Pascal, the email and pdf attachments arrived and thanks for blocking out the email, you of many talents. Like us all I receive more than my fair share of spam, but why the spammers believe I need so much viagra and cialis I just don't understand!! I spoke to Electro again and told them the problem was sorted. Their response was that I was very lucky. The dis/re connection of the battery apparently can cause a spike which will affect the alarm and it was recommended that in future I recharge the battery without disconnecting it(the battery). - This is new to me.

 

[gorselands]

P. S. The car is a w124 1993 Coupe 220ce Can you recommend a workshop manual that covers this model? The Haynes and the CD's seem to leave out the 220 coupe. Is the running gear, electrics etc the same for all the 124 series?

 

[pascal]

Try the site shop http://shop.mercedesclub.org.uk/acatalog/MBOA_Club_Store_Workshop_Manuals_5.htmlThink

Think the brooklands only covers saloons including 220 (93-)
Think the haynes covers coupe but only 230...... (-93)

Regarding Electro, the least he could have done was told you what i said.

I suppose there is a posibility of a spike destroying the ROM memory, am not sure what protection the device has etc. But he gave you this advice before you put the recharged battery back in.

If he thought the spike from a recharged battery (ie 0V - 13.5V) might cause a malfuntion, why didn't he tell you not to put the battery back in. Also if you removed a fuse and put it back in while the alarm was armed, is he saying this would cause a untolerable spike for the unit. I don't think so, but thats my opinion, and I'll reserve full judgement.

In any case, there was nothing wrong with your alarm at all.
So happy motoring Mick.

can it be saved?????

I know this post is ancient but it probably best suits my situation.

I have a Dealer fitted Scorpion 918T that has also lost its way due to a flat main battery. ( previous owner not me)

I have 2 key fobs with 2 buttons & a 2 pos Up/Down slider & both round keys so its not a bad start, also have bought new battery for fob as I heard can be an issue

I have tried many things to resync the keys I tried turning the alarm on pressing on Right twice within 15 secs, I tried turning ignition to acc 2 & holding R button for 30 secs, + the reverse of this with L button with sliders up down & all combinations I could think of to no avail.

all of this I have tried from reading every post I could find on Scorpion alarms. can anyone help I know this is old technology but if I can get it working will provide a valuable deterrrant to prying eyes.

in this instance i believe you have to send the system to scorpon, there are a few post here already about the scrpion 918, do a search.

 

[WHEELS75]

if seen lots of posts about sending off units to be reprogrammed to get new keys programmed but I have the original keys & im rather hoping I might get lucky with a reset, If I had to go to the hassle of un-installing the whole unit sending it Auto-tronics I may as well install a new alarm....?

124 Alarm

Pascal, I'm desperate to get a wiring diagram for the 918 on my 320CE. I've got an intermittant starting problem that I'm sure is dowen to the alarm, but without the wiring diagram , there's no way to fault-find.
Can you help at all?

 

[WHEELS75]

I dont have any installation diagrams for a 918 or a 918t im hoping some one on here might be able to help me too, im hoping I can reset the alarm or failing that will get some help in installing a new alarm. The moderator Pascal would seem to know some things on this alarm but I cannot contact him direct...I have a toad ai606 but I wont instal this unless i have too...

Pascal,

Fantastic!

You wuldn't believe how long I've been looking for this info.....
That intermittant starting fault has got nowhere to hide now!

Thanks again.

You are welcome Paul. I see the link works...

Anybody else want diagrams of other scorpion alarms do not hesitate to ask.
