Technical 2006 Croma Ignition Switch fault

[hicks]

Hi I'm looking for some help or info please.
I have a 2006 1.8 Croma and I have no ignition switch working. No lights coming on cluster.

Checked all fuses and and got micro switches on Ignition switch which tested ok.
Any Ideas what might be causing this?

Hi,
Does the key housing unlock when you put the key in (you can normally hear it)?
Can you turn the key?
Is there electrical power on the car (check hazard lights)?

Hi
There was no click in it so I used it manually but no luck.
I have power in the car hazard lights work and battery fully charged.
Check wiring from switch to steering unit and all seem ok.

Thanks for your help

No click normally means a RFID read failure. Do you have a second key? Does it work?

Tried the spare key but no good.
Could it be body computer fault?
Any one have a complete set for 1.8 Croma (ecu,body computer ignition keys and steering lock?

More likely to be the key module "TEG" reader (you need that as well as the other bits you listed).
It's a right pain to change the lot. You need to confirm exactly what part is faulty. It might actually be better to buy a "virgin" TEG (or other faulty part) from Fiat I was surprised how low the cost of a body computer was but I actually managed to repair mine.

Next thing you need to do is get decent diagnostics on the car. I highly recomment Multiecuscan (MES) www.multiecuscan.net
MES costs €50 plus about £30 for a ELM 327 interface and adaptor leads. This will tell you things like this:

That screen shot was from it running in demo mode as I no longer have a Croma.
