Removing Immobiliser - GRRRR!
Hi Guys,
We are trying to remove a Meta Systems M357TV2 immobiliser that is fitted to sl0th86's K5. The reason is that his bike is flattening it's battery over a period of time. I found a 90mA discharge with ignition off when we fitted the freshly charged battery after the bike had failed to start. I contacted the company and they said different people fit them differently so they can't tell me how to remove it and also I can't go by a schematic because the fitter removes the coloured sleeves from the wires during fitting! OK, so I have removed the indicator flashing wires - all 'point contact' wires i.e. wires that have not been fitted 'in line'. I am left with FIVE (funny number) wires that are all the same colour coding (Black/Green) but which despite being the same colour cannot be connnected together (fuel fuse blew). Sl0th86 has posted pictures of the chaos that is the wiring of his bike following this post. I have a curvy - can any of you guys help? Even with one of those wires disconnected from the immobiliser (see pic) it still starts and runs, but I cannot risk a 'try it and see' approach to reconnecting those wires in some configuration in case I damage the ECM. According to the manual, the Black/Green wires only go from the ECM to the LCD display which looks like B.S. as I have five ends. Also, that picture of a large Diode in line with a Blue/Green wire - what's that all about? I expect it is to do with the immobiliser so I will have to remove that after the above problem is solved. Pics to follow, BIG thanks for your help!!! |

Have a look at my post from when I removed a 357V2 from my K6 pointy. http://forums.sv650.org/showpost.php...7&postcount=10

Re: Removing Immobiliser - GRRRR!
That is DAMN useful AE, thanks. We are removing the entire unit and its wiring, but your jumper links give us a good idea on how to proceed. Thanks!

Re: Removing Immobiliser - GRRRR!
Hope it helps. The jumpers on the connector were just my way of checking before finally soldering the wires together in the loom, since same as you I removed the complete unit and all it's wiring. The picture also shows how infuriating it is that just that one connection is so difficult to track down.
I'm annoyed for not having recorded a couple of things like the colours of the original wires where (2) and (4) connected - from memory they weren't the same colour, and certainly didn't match the colours in any wiring diagram. (2) was easy to confirm with a meter as it was the only connection that shows 12V or nothing depending on the kill switch. (4) was piggybacked onto one of the diagnostic connectors, and the wire it was connected to went to the ECU only. Really I was only certain of that one because I'd eliminated all others. |

Re: Removing Immobiliser - GRRRR!
Mine had a diode which I ended up leaving in place. I'll have to have a look and see if I noted what it did.

Re: Removing Immobiliser - GRRRR!
From the manual, the diode could be to enable the alarm to power the indicators without that power feeding back to other circuits ...

Re: Removing Immobiliser - GRRRR!
I think that's the tip over sensor - edit no it isn't.
