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 CF (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 passenger's cabin.
- 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)
).
