Anyone with KJ Jeep Cherokee immobiliser knowledge

Post by hairyyoda » 04 Sep 2021, 20:21

Hello all
Anyone with any 2007 2.8 CRD KJ Jeep Cherokee immobiliser knowledge ?
Battery was allowed to to discharge and go flat, new battery fitted, now when the ignition is switched on the immobiliser light flashes twice and then stays on solid with no power to the starter relay and the other ignition functions. I am assuming that the two flashes of the immobiliser light before the light stays on solid is telling me something about something ???
Question "would the SKIM key reader have lost it's code"
Have plugged in a OBD code reader in and had a "failed to communicate message" fired back to me on the OBD screen etc.
I know that some of the Chrysler range of vehicles use the DRB 3 protocol for their engine code reading ? and I will need to try a dedicated code reader that is KJ Jeep Cherokee friendly !!!
Anyone with any ideas ???
Thank you
Phil
