Help please if anyone can.ive got a datatool s3 or s4 alarm on my 848 ive nothing but problems with it it was on when i bought the bike.the battery was knackered on the bike so ive changed it today and put new battery in the fobs.still the same probs of not being able to disarm the bloody thing so cant even turn it on without the alarm going off.then stops and resets itself its hard wired into the electrics..any help would be greatly appreciated thanks very much..from pete
Yes - get someone who knows what they are doing with bike alarms. Where are you as some one may have a local contact. I had a Datatool alarm removed last year from my R1 as it very nearly set the bike alight! When I bought a 999R from Ducati Manchester a few years ago they insisted on taking the alarm off before I had the bike too.
It is unlikely that an auto technician fitted it in the first place. The removal is not difficult just time consuming. IIRC the Datatool us a 3 wire system so you need to trace the Datatool wires back to where they were cut into the wiring loom and re join the original wiring, probably with a pigtail of wire as they might be a little short.

I ended up taking my S3 off my last bike after it went tits up. It would wouldn’t turn off the immobiliser part of the system. If you google it there is a way of bridging the terminals inside to fool it. That way you should be at least able to get it running. It’s a temporary fix but should allow you to get it somewhere to get it removed.
It took about 40 mins to strip the alarm out with someone that knew what they were doing. Here’s a pic of it after it came off in case you fancy tracing the wires back. If you undo the top, there’s a little circuit board thing. You bridge A to B and C to D (something like that) with a wire.
Hi I've had 3 of those alarms on separate bikes pack up over the years. Definitely remove, hit with a hammer and then burn the unit. (Please wear appropriate ppe) I've just again removed one from my Triumph, as yours is it was also wired into the loom, If you remove the unit, leave the black plug into the loom installed, use the white plug from the alarm and bridge wires 1 & 2 together and wires 3 & 5 together. This method worked perfectly on mine.(if in doubt contact someone in the trade for your bike) This saved tracing all the wires back and stripping the loom back or taking the alarm apart and bridging the wires there. There's plenty of info on Google on how to do this, if not I used an Auto Electrician to remove one from my R1 a few years back, cost circa £125. A few crude photos I took whilst doing the Triumph, the soldering was just done quickly just to check this method worked before doing it properly. Hope this info helps in some way.
It is possible to put a new main board in from a working alarm and I have done this in the past. However, that will go in time as well. One problem is the Mercury in the nudge system stars to dry out or contaminate the bubble it is in and after that the problems start to mount up. Removal is easy enough by tracing and rejoining any wires that have been spliced into the alarm. They are really only supposed to last about three years odd, and by replacing the board on mine I got it to last over ten. As they get old they become more trouble than they are worth.

I've removed alarms from many bikes, Ducatis, Hondas, Yamahas Triumphs etc. That connector with all the black wires is a standard fitment on Triumphs for the fitment of an alarm. Bikes supplied without an alarm have a dummy plug in it with the terminals you have shown bridged. It is not relevant to any Ducati fitment.
Went on youtube and a guy had same problem.he took the board or breakers out and got 2 paper clips and shoved them in holes 1and 2 and 5 and 6..bingo one working bike again.thanks for all the help i shall have a look at weekend....cheers
Hi I hope you can help me. Thanks for the previous posts, I was able to remove the alarm. I thought it was better than having some thing that has let me down on the side of the road a couple of times. The only problem is that there is not 12 volts on the crank position sensor wiring? Is this part of the alarm wiring? Mine had black wiring from the factory it seems as all the plugs looked like Ducati, I wonder if there should be 12v going from the alarm to the ecu? Look forward to your help and suggestions. vinnychoff
The crank sensors has 2 wires and a screen that connect only to the ECU. I think they run at 5V from the ECU. I wouldn't expect to see 12V there. The alarm usually breaks 2 circuits, the starter circuit and the fuel pump / coil / injector supply. Now that you have removed the alarm: Does the engine crank on the starter? Does the fuel pump run for a few seconds at ignition on?
The fuel pump does run but the bike will not turn over. I wonder if the solenoid is at fault. I have 8 volts with no button pressed and 12 volts when pressed and it clicks. I wonder if voltage is leaking over. If i connect a battery to jump the bike, it turns over but with no spark. I have a solenoid on order so hope this is causing the issue. Are you sure its only 5v? vinny
I am 99% sure that the crank sensor will have nothing to do with the alarm and you will definitely not find 12V there. Since the solenoid clicks when you press the starter button that implies that it is being energised. It may not be making contact internally though. You could try bridging it's terminals to see if the engine turns over or even starts. Be careful though there can be big sparks.
