Hi there
I am aware that this topic was under discussion some time ago.
As I am "new'' I would like to raise it again.
I am looking for a "DIY" immobilizer for my Hilux (2011 3.0 D4D)
Something i can put together hidden somewhere for the day some skelm wants
to borrow my Hilux. :naah:
I am not an electronic specialist but is willing to try if i need to build
a gadget.
Or maybe where to purchase something other than the factory fitted system.

Regards
Duck

There are lots of ideas. From very basic to quite advanced. A simple suggestion is a hidden switch activating a relay on the starter solenoid.

Can still be push started with a relay on the starter. Rather put the relay on the coil. Otherwise fit a fuel cut-off solenoid that's activated by a hidden switch.

He has a D4D. He will struggle a little with the coil. :mocking:

The relay on the starter is simply part of a few measures one needs to put in place. One can also break the power to the ignition switch but you would have to hide it very nicely as this is the area they rip open to see if there are immobilisers etc. connected.

One needs to understand their frame of mind when they are stealing the car. They try to get in and out as quickly as possible. They have been trained on which steps to follow to bypass the security systems in the car and how to quickly find any tracking devices. The moment they have done everything they have been taught and it still does not work they must try and troubleshoot the issue. Now they start doubting if they did everything right and they are working under extreme pressure. They do not have time to troubleshoot so often abandon the vehicle at that stage. It happened to both mine and a colleagues.

My bad ... what can I say, ... I'm a petrol head. :D:
Maybe a relay switch on the diesel pump.

P.S. It's my understanding that you don't need the glow plugs to start a diesel that's already been warmed up.

Don't know that they will all do it, but my MIL had a diesel Golf some years back and the glow plug relay failed. A replacement was special order and very pricey so I just bypassed it with a push button on the dash. It wasn't necessary to heat the plugs if the car had been used in the past hour or more, would just start up.

Something worth considering in your decision on how to immobilise.

if the diesel has good compression a lot will start without glow plugs.My father in law was in Balito he did not even Know that he was to wait for glow plug light to go off before starting until a cold morning up here.

I spoke to an expert that told me to stay away from the electrics as you can mess up the ECU and will then need Toyota to fix it.

Will a inline fuel cut-off solenoid installed in the fuel line from the tank with a hidden switch work?

Hello Jacques
I have also been told by auto electricians to stay away from electronics because of those reasons. They don’t provide a good enough answer though. Will installing relays and a switch damage it or only an incorrect installation may damage it?

Yes, an inline fuel cut-off solenoid installed in the fuel line from the tank with a hidden switch will work. Use an anti-hijack type switch so it can be hidden or concealed properly.

One can also break many circuit from behind the fuse box with a relay and a switch. Behind the fuse box to conceal it and wires running to the relay must be concealed as well. The ignition, the computer box, etc. can be done there. Same thing as pulling out a fuse.
