How To Proceed With Troubleshooting

HINT: 

• Use these procedures to troubleshoot the navigation system.
• *: Use the Techstream.

1. VEHICLE BROUGHT TO WORKSHOP 

   NEXT: Go to next step 

2. INSPECT BATTERY VOLTAGE 

   Standard voltage

   11 to 14 V

   If the voltage is below 11 V, recharge or replace the battery before proceeding.

   NEXT: Go to next step 

3. BASIC INSPECTION 
   1. Turn the engine switch on (ACC).

      Result	Proceed to
      CAN DTC is not output.	A
      CAN DTC is output	B

      B → Go to CAN Communication System. Refer to  DIAGNOSTIC TROUBLE CODE CHART 

      A: Go to next step 

5. CHECK FOR DTC 
   1. Check for DTCs and note any codes that are output.
   2. Clear the DTCs.
   3. Recheck for DTCs. Based on the DTCs output in the first step, try to force output of the navigation system DTCs by simulating the conditions indicated by the DTCs.

      HINT: 

      • If the system cannot enter the diagnosis mode, inspect each AVC-LAN communication signal and repair or replace problem parts.
      • Even if the malfunction symptom is not confirmed, check for DTCs as the system stores past DTCs.
      • Refer to the detailed description on the diagnostic screen as necessary. Refer to OPERATION CHECK .
      • Check and clear past diagnostic trouble codes. Check the diagnostic trouble code and inspect the area the code indicates.
      RESULT
      
      

      Result	Proceed to
      DTC is not output	A
      DTC is output	B

      B → Go to step   8 

      A: Go to next step 

6. PROBLEM SYMPTOMS TABLE 
   RESULT
   
   

   Result	Proceed to
   Fault is not listed in problem symptoms table	A
   Fault is listed in problem symptoms table	B

   B → Go to step 8 

   A: Go to next step 

7. OVERALL ANALYSIS AND TROUBLESHOOTING 
   1. Check the hard disc. Refer to OPERATION CHECK .
   2. Terminals of ECU. Refer to TERMINALS OF ECU .
