DTC 1202: DVD Low 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 falls below -4°F (-20°C). The unit is designed to shut down to protect the audio-navigation unit ECU. This is usually caused by very cold exterior temperatures. 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 temperature is above -4°F (-20°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)
).
