DTC 1201: DVD High Temp
NOTE:
- Check the vehicle battery condition first (see 12 VOLT BATTERY TEST ).
- This navigation DTC sets when the internal temperature of the audio-navigation unit ECU rises above 158°F (70°C). The audio-navigation unit is designed to shut down to protect the audio-navigation unit ECU. This could be caused by an inoperative audio-navigation unit ECU fan or if the dash temperature exceeds the maximum. Do the troubleshooting when the unit is within the allowable temperature range.
- Before you troubleshoot, make sure to follow the General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).
- Check that the fan screen on the back to the audio-navigation unit is not blocked. Clean it if necessary.
- Check that the temperature is below 158°F (70°C) in the dash.
- Clear the hard error code (see HOW TO CLEAR ERROR HISTORY ).
- Turn the ignition switch to LOCK (0), and then back to ON (II).
- Check for the hard error code (see HOW TO CHECK ERROR HISTORY (NAVIGATION DTCS)
).
