I had trouble a couple of years back with the immobiliser coming on without being set, the problem appeared to be the soldered joints where the immobiliser module was fitted into the vehicle wiring loom. I remade all the joints and the problem disappeared until a couple of months ago. Part of the wiring installed with the immobiliser module is a 5amp inline fuse spliced into a wire from the ignition switch to the immobiliser module which I guess is the power feed for the unit. I have traced every wire from the module which is sited behind a trim cover on the right of the driver under the dash. Nearly all the wires go to circuits associated with the ignition switch, LED and jack socket in the cowling under the steering wheel except two that go direct to the engine bay in the fuel pump area.
The problem was first discovered when the car wouldn't start and on inspection I noticed the LED on the steering column cowl was not flashing. A check of all the wiring under the cowl showed no loose or broken joints but wiggling the 5 amp fuse fixed it. Got a new fuse holder and soldered into the circuit, problem solved or so I thought. Now the supply via this fuse just goes without warning and the engine cuts out and to restore things to normal I take out the fuse put it back and everything works. I assume the immobiliser is cutting the circuit to the fuel pump solenoid which is why the engine dies but the same process also turns of the entire system.
The fuse holder was one I got with a car radio kit and wonder if it's up to the task. I have considered the jack socket on the steering column but cannot see how since the problem appears to be power to the module and there is no power to any terminal on this socket, I'm guessing this provides a trip function to start a timer allowing the starter solenoid to be operated.
I am thinking of removing the immobiliser system and installing another proprietary off the shelf system. Has anyone done this?
All assistance greatly received.
