Do the LEDs light up when you push the button, or not? (also check with smartphone camera to see if they're IR) There's a model number written on the board next to the ATTiny that's a bit hard to read - see if you can grab a pic with the other chip (the QFN)'s numbers visible, and that number (highlighted in this pic so you know what i'm talking about)  higher resolution would be useful too. It's clearly some form of universal case around the thing, so whatever it is we can expect it to be cheap and chinese.

I'm gonna go out on a fairly short limb; Antenna unit, model C2W3, board revision date 12th of August 2005, which would imply it's been there for quite a while. The model number didn't bring anything up for me either, and the ATTiny won't get you anywhere (they're generic cheap microcontrollers used in all kinds of poo poo) - as rdb said, time to follow that wire.

some texas redneck posted:Gonna guess his initial guess of something from a buy here pay here lot is correct - they often install something to render the vehicle inoperable in case of missed payments. They generally either have a way to enter a code every 2-4 weeks, or operate via some kind of cellular connection that checks in daily/weekly/etc. The antenna does look suspiciously like what one would expect for a lovely cellular antenna - though usually in-vehicle systems would use a sticky patch antenna like this whatsit. No visible SIM card or SIM slot, too, and an attiny definitely doesn't have enough horsepower on its own to do much with cellular - looks more like a short-range radio link to me, something like a two-way security/keyless entry system perhaps. Of course the other chip could easily be a CDMA cellular radio chip, but I'm not seeing enough RF can for that either... dammit meatpimp follow the wire and solve the mystery! literally a fish fucked around with this message at 11:22 on Oct 19, 2015 |

meatpimp posted:Yeah, lock/unlock fobs are standard. I'd believe something like a remote start, but anything retail I've ever seen has some type of identifiable markings on the PCB... plus, if you look at the case, it's completely generic/non-matching of the PCB. There is a button on the board for number 1, but nothing underneath 2 and 3. That could just mean "$80 chinese remote start", mind you. Case commonality is fairly, well, common (pardon the pun) Good luck finding the box on the other end of the wire! hopefully it has some form of model number.

Pretty much every brand has their own specific tool and set of software. For Volvos, it's the VIDA software and DICE tool, and even with pirated copies of that hardware there's limits to what you can do. You can get some expensive tools that will be able to do SOME things on all brands, but the only thing you're guaranteed without a manufacturer specific tool is diagnostic codes and live sensor data. Where you start is by dropping $1-3k per brand you want to touch on equipment and software :V

LloydDobler posted:The funny part about the Volvo tool is it appears to be the company that makes it for Volvo that is gray market selling it on the side. It is marked with official Volvo logos and everything, QC tags and all, it looks identical to the shop units I've seen. I bought one for $200, it allows me to pull proprietary codes and talk to the car modules and reset lights - I reset my SRS light today in my C70, I've had a passenger airbag switch installed to keep my daughter safe, she's old enough now that it's unnecessary so I took it out. Module programming is the only thing you can't do with the pirated tool, I have the same one you have. It'll do anything that doesn't require a purchased software download, but you can still do those in the USDM with a 3-day VIDA subscription once a year to grab all the updates. Only things you can't do without being a dealer are security system related, iirc. Rather amusingly this means on the P2 Volvos you have to have the dealer replace the rear-view mirror if the auto-dimming fails, because the rear-view mirror has the electronics and antenna for the keyless entry system in it
