If BCM loses data communication with IPC and ignition is on, Code B336 will be set. The problem is a result of 7-volt or ground fault to IPC or double open circuit in data communication line between IPC and BCM. If this failure occurs, cruise control will disengage (if engaged) and headlights (if on) will function on low beam.
