Audio-Navigation System DTC Troubleshooting: 1204

DTC 1204: HDD High Temp

NOTE:

	Check the vehicle battery condition first.
	This navigation DTC sets when the internal temperature of the navigation ECU (HDD) rises above 158 °F (70 °C). The audio-navigation unit is designed to shut down to protect the navigation ECU. This could be caused by an inoperative audio-navigation unit fan or if the dash temperature exceeds the maximum. Do the troubleshooting when the unit is within the allowable temperature range.
	If the audio-navigation unit displays an error message when you turn on the navigation system, follow the instructions.
	Check that the fan screen on the back to the audio-navigation unit is not blocked. Clean it if necessary.
	Before you troubleshoot, make sure to follow the General Troubleshooting Information.
