2000 GSR: Immobilizer?

Yes, your keys have chips in them. Why?

Someone stole my 2000 Acura Integra GSR, and I had assumed they broke in, started it, and drove off.

Just wondering how they did that...

perhaps they brought along their own rigged immobilizer module? I've found references to an anti-theft "immobilizer" system,but no mention of RFID-chipped keys.IIRC,the "immobilizer" is a separate module.

on my 94 GS-R,they push-started the car even though it had an alarm with starter lockout.Drove it off at 3:40AM with the alarm blaring,too. "gone in 60 seconds".

You need to have a hidden fuel cutoff switch,and maybe even take the ECU indoors with you at night.

F-ing G-D thieves,we should be allowed to shoot them on sight.

You should move to Texas. That's exactly what someone did last week. Still no word on whether the DA's going to press charges, but public opinion here has so far been mostly in favor of the shooter.

In louisiana, being on your property and not speaking english well is enough reason to shoot them dead.

It's my understanding that dealerships have "skeleton keys" that will open any Honda. It may be that there are stolen copies floating around of such keys.

It's also possible computer hackers have found a way to defeat the security. It can't be much harder than hacking any other computer-based security setup.

it depends on whether the Hondas use an ECU-based "immobilizer" where an implanted code in the ECU has to match what the RFID chip in the key generates. Then they would have to change the ECU out to get the car to start with their RFID key.

ISTR that the later Integras had a separate "immobilizer" module(just a starter disable) that could be unplugged and replaced with a jumper module or hacked module.

IOW,it's just like aftermarket alarms,easily defeated.

More likely they borough their own _Tow Truck_

I just did some quick studying of the immobilizer system in my manuals.

The '00-'05 Integra/RSX's immobilizer consist of three components: The transponder in the key, the control unit/receiver, and the engine's computer.

The receiver is right next to the ignition lock cylinder. When the receiver senses the correct signal from the key's transponder, it sends a coded sequence back to the engine's ECM. If the transmitted code is correct, the ECM causes the fuel system to be operated in a normal manner. If the signal is wrong, the fuel system will be disabled.

And how will the ECM disable the fuel system? By refusing to ground the Main Relay (probably by leaving terminal 8 open).

Are you thinking the same thing I'm thinking?

No...

Not following you...

Does it SAY that? I thought it might inhibit injector operation,shutting them off totally. (at least in the RSX,a newer system.) That's what happens in my Sentra SE-R SpecV. That also is "disabling the fuel system".

Just not grounding the main relay leaves it vulnerable to jumpering,very simple. An "immobilizer" HAS to disable the ECU to be effective.

If that's the case,best to install a hidden fuel pump disable switch. I wish I had done that for my 94 GS-R,I had the parts all ready for installation,just didn't get to it in time. It cost me big time.

No it does not. It *does* say that the ECM will refuse to ground the Main Relay. I'm guessing on the Terminal 8 thing. Terminal 8 is the activation line for pre-'02 Main Relays.

Around '02, Honda split the Main Relay into two separate relays, one for fuel, for ignition. I haven't scrutinized the diagrams to see exactly what goes where. Yet.

I wonder how honest my (factory) manual is. It claims fuel disable, and nothing more.

That's too bad. The late John Ings had just that advice up on the FAQ before I took it over.

There're only two lines to the fuel pump, and one's a ground. Splice into the live wire and it would be a rare crook indeed who could figure that one out. No power, no fuel.

Even if the fuel pump runs, the ECM can simply fail to signal the injectors. Ditto for the ignition. You can't have a running engine without the ECM participating.

You're right of course. That's why I wondered earlier how honest the shop manual was. It would be trivially easy for Honda to tell the ECM to disable spark and injectors as well as the fuel pump.

But none of this explains how the OP's car was stolen in the first place, which is what this whole thread was about.

Quite simple. Get a truck, lift front wheels and pull. Say goodbye to car.

if it had an immobilizer, it was either tricked, or more likely, the car was simply towed away.

Tegger wrote in news:Xns99F05A7C3E248tegger@207.14.116.130:

it would seem that the ECM does NOT disable the injectors,just the relay,and they just jumpered the relay,then pushstarted the car.

Or they brought along their own ECM,swapped it in,and then jimmied the ignition switch,with their matching key close enough for the key reader to query it. That's a bit of a stretch,but not impossible.

If you install a fuel pump cutoff switch,you should remove the rear seat to access the fuel pump wires,not under the dash where the mod would be easily found.Then run the wire under the carpet to somewhere reachable from the drivers seat.

You don't even have to live in Texas to do that. If I caught someone trying to steal my car, I'd tie them to a fence and chop off their balls and make them eat them, then I'd shoot them! If it was a woman I'd tie them to a fence, and then have my way with her and then I'd shoot her. I'm a nice person, I'm just very protective of my car.

What about just putting The Club on the steering wheel? How good are they?
