If it's the wireless ignition nose (WIN) I understand there is a recall on this. Am I correct on this? When I put the key in and turning it the car turns on. The only fault code I have seen and the technician is --key damaged. When you say "some data can be looked at on the scan tool" is that something done at the dealership? If so, is it a particular machine that is used? Please advise. Thank you.
There was a recall on the WIN for a few vehicles built in a small time frame in 2010. Yours could be part of the recall, but if there were any open recalls on the car then the dealer should have caught that when it was in for service, they would have checked when your paperwork was written up and then when the tech programmed the key the scan tool would have told him also.
Fault codes store in control modules when a problem is seen. Reading fault codes (and looking at the data to see what is happening) is done using a scan tool, in this case the most common and likely tool would be the WiTech since that is what the dealer uses.
