DTC 1405: Audio Error 5 (HDD Error)
NOTE:
- Check the vehicle battery condition first (see BATTERY TEST ).
- This navigation DTC sets when the internal temperature of the HDD rises above 158°F (70°C). The unit is designed to shut down to protect the HDD. This could be caused by an inoperative audio-navigation unit cooling fan or if the vehicle cabin temperature exceeds the maximum. Do the troubleshooting when the audio-navigation 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 temperature is between -4°F (-20°C), 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), or press the engine start/stop button to select the OFF mode, then back to ON (II), or press the engine start/stop button to select the ON mode.
- Check for the hard error code (see HOW TO CHECK ERROR HISTORY (NAVIGATION DTCS)
).
