HI
so you dont have the +after egnition for that you dont have the commenecation with
ecus/model
you can check your fuse box because if you dont have egniton evene immo off can not start your car
good luck
PS: witch tipe of keys you have with blide or the inteligent one(like the car)

The key is with blade, the owner of car changed the ignition switch without benefit, cluster keeps off except the middle display show (immobilzer Active) and when turn key nothing occured (no leds in cluster and no sound of march).

kessy module seems ok, when i disconnect it an error appear in cluster and key stuck in the ignition whatever i turn it to left or right (even wait for 10seconds) - the 2 mosfets and 6 resistors all are okkay. [SO KESSY is OK].

Which fuse i should look for ?

If i make immo off for ECU, you dont think the car will start ?
I thought there is a problem in OBD2 port which make scanners cant detect any module even there is a power in the obd2 port.

Hi
Check the can lines in obd socket
Sometimes the can lines break down

It is bosch ME7.5
I checked today 12v gnd and kline between obd2 port and ECU socket ... all are ok.
I check the important fuses ... ok.
I make a jumper between fuse 26 (kessy)and 36 (12v) and cluster leds turn ON but fvdi cant read any module.
I try to learn a key by fvdi there is a response occured in cluster and the key make now click sound when enter it and cluster give lights without using jumper between fuses 26 and 36.
That happened only when i press brake pedal during the process of learning key.
Car lights keep blinking and strange sounds occured when i try to run the car but it wont start and then after 1 minute it return to initial state ... no lights and immobilzer active message appears again.


Any ideas ?
