Removing NATS (Nissan Anti Theft System) from GU III 4.2TD Injector Pump

[davejones]

There's a procedure in the manual for over riding the NATS system. I'd give page numbers but it probably varies from model to model.

Basically it involves turning the ignition off for a minute, then turning it to on for 5 sec, off, on for 5 sec, off, on for 5 sec, off, then starting the vehicle (from memory, it'll be close if not right.)

But I found it a bit hit & miss. Got me out of jail more than once before I did this. But at times changing keys or walking away and leaving the truck for an hour and coming back would start it too.

It's a god damn pain in the arse. No question.

If you have a NATS equipped truck, get rid of the CSOLU. It's a nightmare waiting to happen.

I think it's ironic that the best thing about owning a 4.2 is that there's bugger all electronics, and yet here's this electronic thingumy that is just waiting to give you grief.

I'm going to wire up the imobiliser from the Dynamco central locking & immobiliser again next. I disconnected it to make it factory standard to prove that wasn't part of the problem, but at least I can reverse that on the side of a track somewhere, and in the mean time still no-one can steal it. Not that it's much of an issue down here.

Thanks guys,

Happy to help.
