Service bulletin SS1034682

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Service Solution for Updated Common Telematics Platform (CTP) Installation and Activation Procedure. Some new CTPs being installed in the field have failed to activate and do not communicate with Detroit Connect back end. The activation of the CTP requires that the VIN and CTP serial number pair is transmitted from DiagnosticLink to the Detroit Connect registration server. When using the old procedure, there may be some factors that may prevent that VIN and CTP Serial Number pairing data from uploading to the server.
