Bulletin Summary
Center Information Display Switching off. INFORMATION The brightness of the CID will reduce and may switch off completely due to high temperature rise inside the vehicle. This situation is to protect the function of the CID. After lowering the temperature, the normal functions are restored. The increased temperature, protective switch-off is the reason for the fault. The fault code does not indicate a defective head unit. The normal maximum temperature operation for the head unit is between 167 and 194 F. Within these values, the CID will gradually diminish in brightness until it completely switches off. Replacing parts or programing the vehicle will not rectify the situation. The root cause is the very high temperature and is not a fault of the vehicle's systems.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
