OBD-2 Input to the PIC

[Acetronics2]

Hi, Ioannis ...

My car is a " quite fully " computerized one ...

and , If I want to buy a new key, I MUST go to the dedicated garage ...

You know why ???

All the new key logging is made being connected to the OBD plug ... YESSS !!!

I suppose you understand what this mean ... and some functions do not have to be explained on the Web ... or at your own risks ( There's a superb .444 cal. 94' model Winchester repeating gun home ... for your info !!! )

The answer to your doors, glasses ...etc, control is YES ( but may be not with all car models ...)

Regards

Alain

I think you misunderstood my position. I was talking about a central control unit to control main functions of the electric devices in a car while being able to inform the driver about faults.

For example to power on the Heater in the seats, lock doors by remote control without intervention to the electrical connections, etc. My job is not to steal cars! I already have lost a Honda Civic VTi because I did not protect it fully... :-(

Now we developed a positioning system with GPS-GSM-GPRS to protect any moving object, car, boat etc. Lesson learned.

Anyway thanks.

Hi, Ioannis

I know you for a while and understand you're honest ... of course !!!

But you're not the only one on the line ... the problem is here.

I also owned a 1.6 i Civic ( 130 PS ... no VTEC ) for 15 Years ... and the best antitheft system I found is to cut the Starter relay wire ... of course, a simple radio switch re-enabled the line as wanted !!! ( an old Veglia alarm system dating 1981 ...) ...
Doesn't keep from using a heli to lift the car ... I admit ...

Now, with 2 children ( and a wife ...) It's become a 2.0l Accord !!!

Ok, back to us ...

I 've read a bit about ( Laughs ...) and discovered you can access all the functions physically linked to the OBD plug ... as well as engine, anti-theft, seat heating, windows shutting ...
All those functions can be read ( and data modified ...danger here !!!) from the dedicated terminal !!!
It was just planned at first for easy maintenance and diagnose at the garage ...

Those function codes are simply called "reserved" in the standard coding tables ( those you can freely download ...) and belong to constructors.


I'll make you cry a bit, now ...

I bought a 2nd hand 2004' 1600 Civic, 4 doors for my wife ... and of course, less than a week later, she forgot the unique key inside !!!

Took me less than 5 Minutes to re-open it ... without damaging anything !!!

Understand, if I had been the thief with my Obd terminal ... the car had been started in seconds ...

The simplest anti theft will here be the best ... Engine not starting !!!

I took my Dodge pickup to Vegas a few weeks ago, went to all the casino's, parked in the free parking, etc.etc. Everywhere I went, after parking, I popped the hood (bonnett?) and took the main ignition coil wire with me. (Was that an ignition coil wire in my pocket or was I just happy to see them )
But as you say, would that stop a relatively knowledgable thief from taking a spark plug off a cylinder and putting it in the main wire's place (actually, it would in this case because the main coil wire is a lot longer than any plug wire)? Probably not...
And you guys have given me some good ideas on what to do with the CAN bus, sniffing the bus, logging parameters, etc. Now I just have to buy a car with CAN instead of ISO9141.

...or was I just happy to see them )

sure you were!

Thats easy. Every car dealer has one!!

... and the best antitheft system I found is to cut the Starter relay wire ...

I agree. I thought of it too late of course... Now I own a Skoda Octavia RS that has all the busses (ODB and CAN) to play with.

Doesn't keep from using a heli to lift the car ... I admit ...

In my town 3-4 years ago they used a fork lift to take a car (Mercedes) that was parked inside the two lines of parked cars!
That made me proceed to the design of the GPS-GPRS system that is quite capable. Now it is selling about 0-1 pcs per month! Great success!

Yeap, I did the same on my father's old honda. They open easily. But a video about the latest BMW prooved that the brand new "safer" locks are super easy to unlock without damaging the car!!! The company that makes the tools is German too!

I agree second time, make the car unable to start is best way, simple and almost full proof.
