CAN Bus attack discussed here multiple times and it can be prevented by CAN/LIN immobilizer. But recently I've read a forum here (2022 RAV4 stolen) where Toyota UK bulletin WB853 was mentioned and special shields( part GBNGABRACK01) get installed to block access to CAN Bus through headlights.
Is anyone familiar with it?
Also I have a questions : What is this bulletin WB853 about? Where to get this kit GBNGABRACK01 in North America (or shipped to North America)?

p.s. My car has an immobilizer plus some other surprises but it would be nice to prevent folks to get into car.
p.p.s. This kind of shields can be easy made, but why to bother if you can buy it

I only learned about this last week and did see a video showing the thieves access the can-bus near the L/H headlight. Coincidently my RAV4 is booked for service soon. I asked about this issue and was offered a security plate installation for a £70 charge. I'll get it done but think Toyota are being a bit mean.

Same story here they break in through headlight.
I would like to see more detailed images of those plates. Posted images in GB forums doesn't show much details.

I've heard of this "security plate" before. Details like part number?

It's GBN GA BRACK01, but no other details or images available.

In addition to the shroud around the headlight connector toyota should add a bear trap.

Those morons should install firewall in CAN bus to prevent unlock signal from external points.


So, I can see this Toyota's "security plate" solution is the same like solution for high voltage cable corrosion - we are screwed something up and then trying to fix it with band-aid.
What is the point to secure headlight connector if another connector exists. I guess it prevents only from thieves with hacking devices which have connector for headlight, not ones equipped with two probes.

Saw that Miller CAT is coming out with a solution for this problem.

It's a good news. I have an experience with CAT shields - solid product.

There is a very simple fix for security. I did this on my 1998 rav4 and have done it again on my 2015 rav4 xle awd. I added a toggle switch oncthe cranking circuit. It looks like the car will run when the key is in the ignition but when you turn it over theres no power to the cranking circuit. I installed the toggle under the dash where you cant see it. I just reach up and click the toggle switch and it turns over as normal. A five dollar fix to make the vehicle super hard to steal. Dont see many thieves whipping out a multimeter trying to diagnose a "short"

It's easy on older cars, but not so much on modern ones without triggering error code. Hybrids adds complexity as well.

I've been warned that incidents of Toyota vehicle theft through the moon roof and OBD2 port are occurring in California. I don't know the frequency but it is happening apparently.

I was thinking of installing a dummy obd2 port that isn't hooked up to the can bus to fool casual thieves as a passive theft deterrent measure.

Is there a roof rack accessory that doesn't generate too much wind noise and hurt gas mileage I could throw up there to physically block the moon roof as an entry point?

You can buy this as a fake obd port: For TOYOTA Dummy OBD2 Port DUMMY OBD ALARM SIREN Anti Theft Security Guard | eBay
To protect moon roof - OEM or aftermarket crossbars will work well in this case. Front cross bar just in the middle of moon roof.

I got a tracker and immobilizer installed a couple of days ago. The person that dealt with me says there is something else known as “the vault”. He said it prevents the door from opening, no matter what they do. The only way they can get in is to break the window. Has anyone ever heard of this device?

I haven't heard about this particular device, but it reminds me situation I was dealing in 90s: many non basic aftermarket alarms were equipped with set of door locks controlled by alarm only. So, you have to disable alarm first before opening door. Disconnecting alarm or battery didn't help - doors remains locked.
Installation was strait forward - separate locks for doors, hood and trunk with separate wiring circuits.

PS. Anything which uses existing door looks is actually ineffective because thieves break door locks with brute force (at least here in Canada)
