See step  2

1. Confirm problem symptoms
   1. Check the functions for which the problem symptoms occur. (Navigation function, audio function, etc.)
   2. If the malfunction occurs for radio, there is a high chance of the malfunction being caused by external factors.

      HINT: 

      • If the malfunction occurs depending on the location, consider transmission lines, overhead wires, neon signs, trucks or motorcycles, wireless transmissions from vehicles, buildings, etc., as the cause.
      • If the malfunction occurs depending on the channel (broadcast station), consider excessively strong radio waves, excessively weak radio waves, poor quality signal, unstable signal, etc., as the cause.

1. Check that condensation is not likely to occur in the cabin and that the temperature is not -20°C (-4°F) or lower, or 65°C (149°F) or higher.

   HINT: 

   • A humid cabin and a rapid change in temperature may lead to condensation. Condensation in the cabin may cause a short circuit.
   • The audio and visual system may not operate normally when the temperature is -20°C (-4°F) or lower, or 65°C (149°F) or higher.

See step  7

HINT: 

Using the GTS, check for DTCs.

1. Check for DTCs.
   1. Record the results of any DTCs (latest/confirmed)

      Body Electrical > Navigation System > Trouble Codes 

      HINT: 

      • Check the freeze frame data for both latest DTCs and confirmed DTCs.
      • If freeze frame data is stored, a snow icon is displayed to the left.

      Item	Details
      Latest DTC	Indicates the latest malfunction judgment results during the current trip
      Confirmed DTC	Indicates DTCs that have been confirmed

2. Clear the DTCs.

   Body Electrical > Navigation System > Clear DTCs 

3. Recheck for DTCs.
   1. Based on the detection conditions of the DTCs, simulate the malfunction conditions and check if the DTCs are output again.

      Refer to DIAGNOSTIC TROUBLE CODE CHART [09/2022 - ] 

      Body Electrical > Navigation System > Trouble Codes 

      HINT: 

      If DTCs are output during the speaker line continuity inspection for a vehicle equipped with a stereo component amplifier assembly, refer to Utility.

      Refer to UTILITY [09/2022 - ]
