I had to disconnect my battery to work on something and after reconnecting everything works but the ICS. There is not a malfunction, just an ICS flashing indicator and a message that it is unavailable when the car is started. Looking in the user manual on page 356 there is a bullet that describes the issue: "System initialization may not have been performed after removal and installation of the 12-volt battery. Perform system initialization". There is no reference on how to actually perform the initialization. Has anyone run into the same issue and if so can tell me how to kick this off?
