CC - No Communication with the J519 Vehicle Electrical
System Control Module/Body Control Module
July 22, 2016: Update to Model Year Applicability.
If no communication can be established to the Vehicle electrical system control module J519 (address
word 09) in Guided Fault Finding or Vehicle Self Diagnosis, it may be necessary to cycle door locks. It is
recommended to cycle both the remote locks and the driver's door lock switch when attempting to
communicate with the module using the scan tool. Ensure all vehicle doors are unlocked before
communication is retried.
