How can I disengage the engine immobiliser?

please say what disengage means.
1: defeat?
2: make it work right?
3: stop the lamp from glowing and being unhappy (1996 MB)


Sig: I must ask questions first, I'm blind, and my tools can't reach, dig?

make sure that a signal is generated from the crank position sensor when cranking the engine if not sensor is faulty . Otherwise check for spark at plug leads check for fuel pressure at the rail and make sure immobiliser is disengaging

have you tried a code reader ?

hi, i have nissan terrano wen i switched on engine light flash and start engine its start then go of.nissan terrano patrol engine

Switch on head lights or cabin light. If they doesn't come on or is weak, the battery is flat. Ensure that you switch off the lights.
With ignition switched on, assuming the lights on the instrument panel cames on and your immobiliser is deactivated, turn ignition to start. You should hear the solenoid at the starter making a click sound. If not, the battery is flat or the starter solenoid is faulty. If it does make a click sound, the battery could be too low to turn the starter or the starter is faulty. Assuming the immobiliser is working correctly, and the starter tries to turn the engine but it doesn't want to turn, the gasket could be blown and the cylinder filled with water, or the engine could be seized.
Hope it is not the last case. MarioCpt

I would troubleshoot the wiring and all ground points to eliminate that. Then swap out the ECM to see if is defective.

Check the switch on the seat, of all places. There's a safety switch on the seat that will kill the engine if it's not engaged when do anything other than start and run the engine.

If the switch checks out, get back with me.

If, when you switch the ignition on, you get a dash light on, the symbol is a car with a key overlaid, you have somehow activated the immobilser You could try disconnecting and reconnecting the battery, this may reset the immobiliser, If this does not work you will have to contact a Hyundai dealer to get the immobiliser unlock code.

dealer only to re programme key into car it can only be done with vehicle, not away from it .Sorry for no easy fix unless you want to disengage the factory immobiliser,which if its a diesel is a fairly simple procedure but not for a petrol engine

There might be an immobiliser fault or a problem with the key transponder but try the following before you call the dealer or local auto locksmith.

Disconnect the battery and leave overnight. Next morning open the car, put the ignition key in and switch on the ignition - then connect the battery.
