OVERVIEW:
This bulletin involves Flash Reprogramming the Instrument Cluster, Cabin Compartment Node (CCN).
NOTE:
After the module flash is performed, the ambient temperature will not automatically update, but it will start at 77 °F (25 °C). To get the temperature reading to update, the vehicle must be driven above 20 MPH for up to 2.5 minutes. For the quickest results, drive the vehicle on an expressway.

SYMPTOM/CONDITION:
Customers may indicate that the temperature display in the instrument cluster is not accurate.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with TechCONNECT and the appropriate Diagnostic Procedures, verify all systems are functioning as designed. If DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the Symptom/Condition and there are no other CCN or temperature sensor issues, perform the Repair Procedure.
SPECIAL TOOLS/EQUIPMENT REQUIRED:
REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE:
The StarMOBILE(TM) in standalone mode can be used for the flash.
NOTE:
Before performing this Repair Procedure, the operating software in the StarSCAN(R); must be programmed with software release level 8.02 or higher.
The software release level is visible in the blue header at the top of the StarSCAN(R) screen.
NOTE:
The StarSCAN(R) diagnostic scan tool fully supports Internet connectivity. However, to take advantage of this feature you must first configure the StarSCAN� for your dealership's network. Make sure the StarSCAN� is configured to the dealership's network before proceeding. For instruction on setting up your StarSCAN� for the dealer's network refer to either:
"DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online Documentation", or refer to the StarSCAN(R) Quick Start Networking Guide. The StarSCAN(R) Quick Start Networking Guide is also available on the website under the "Download Center".
