HOW TO PROCEED WITH TROUBLESHOOTING
HINT
- Use these procedures to troubleshoot the audio and visual system.
- *: Use Techstream.
- VEHICLE BROUGHT TO WORKSHOP NEXT: Go to next step
- 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
- BASIC INSPECTION Turn the power switch ON (ACC). Check whether or not the display appears on the multi-display. RESULT Result Proceed to Display appears A Display does not appear B B --> Go to step 7 A: Go to next step
- INSPECT COMMUNICATION FUNCTION OF MULTIPLEX COMMUNICATION SYSTEM (BEAN)* Use Techstream to check if the Multiplex Communication System (MPX) is functioning normally. RESULT Result Proceed to MPX DTC is not output A MPX DTC is output B B --> Go to MULTIPLEX COMMUNICATION SYSTEM A: Go to next step
- CHECK FOR DTC Check for DTCs and note any codes that are output. Delete for DTC. Recheck for DTCs. Based on the DTC output in the first step, try to force output of the audio system DTC by simulating the operation indicated by the DTC. 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. This is because the system stores past DTCs. Refer to the detailed description on the diagnostic screen, as necessary. «DIAGNOSIS DISPLAY DETAILED DESCRIPTION»(ref-387171-S02976621102011022400000) . Check and clear past diagnostic trouble codes. Check the diagnostic trouble code and inspect the area the code indicates. RESULT Result Proceed to DTC does not reoccur A DTC reoccurs B B --> Go to step 8 A: Go to next step
- 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
- OVERALL ANALYSIS AND TROUBLESHOOTING Terminals of ECU. Refer to «TERMINALS OF ECU»(ref-387171-S34649818612011022400000) . Inspect the front No. 1 speaker.

- Illustrations may differ from the actual vehicle depending on the device settings and options. Therefore, some detailed areas may not be exactly the same as on the actual vehicle.
- If the system cannot enter the diagnostic mode, inspect all AVC-LAN communication components and repair or replace problem parts. Refer to «AVC-LAN Circuit»(ref-387172-S15573264402011022400000) .
- After the power switch is turned ON (IG), check that the map is displayed before starting the diagnostic mode. Otherwise, some items cannot be checked.

- START DIAGNOSTIC MODE There are 2 methods to start diagnostic mode. Start the mode by using one of them. Method 1 Start the hybrid system. While pressing and holding the "INFO" switch, operate the light control switch: OFF --> Turn ON --> Turn OFF --> Turn ON --> Turn OFF --> Turn ON --> Turn OFF. The diagnostic mode starts and the "System Check Mode" screen will be displayed. Service inspection starts automatically and the result will be displayed. Method 2 Start the hybrid system. Press the "DISP" switch. From the display quality adjustment screen, touch the corners of the screen in the following order: upper left --> lower left --> upper left --> lower left --> upper left --> lower left. The diagnostic mode starts and the "System Check Mode" screen will be displayed. Service inspection starts automatically and the result will be displayed.
- FINISH DIAGNOSTIC MODE There are 2 methods to end diagnostic mode. Use one of them. Turn the power switch OFF. Press and hold the "DISP" switch for 3 seconds.
- DIAGNOSIS MENU The "Diagnosis MENU" screen will be displayed by pressing the menu switch on the "System Check Mode" screen.
- CHECK DTC Read the system check result. If the check result is "EXCH", "CHEK" or "Old", touch the displayed check result to view the results on the "Unit Check Mode" screen and record them. HINT: If all check results are "OK", go to the communication DTC check. If a device name is not known, its physical address is displayed. HINT: When proceeding to view the results of another device, press the service switch to return to the "System Check Mode" screen. Repeat this step. Read the communication diagnostic check result. Return to the "System Check Mode" screen, and press the "LAN Mon" switch to enter the "LAN Monitor" screen. If the check result is "CHEK" or "Old", touch the displayed check result to view the results on the individual communication diagnostic screen and record them. HINT: If all check results are "No Err", the system judges that no DTC exists. The sub-code (relevant device) will be indicated by its physical address. When proceeding to view the results of another device, press the "Service" switch to return to the original "LAN Monitor" screen. Repeat this step.
- DTC CLEAR/RECHECK Clear DTC Press the "Code CLR" switch for 3 seconds. The check results are cleared. Recheck Press the "Recheck" switch. Confirm that all diagnostic codes are "OK" when the check results are displayed. If a code other than "OK" is displayed, troubleshoot again. Press the "LAN Mon" switch to change to the "LAN Monitor" screen. Confirm that all diagnostic codes are "No Err". If a code other than "No Err" is displayed, troubleshoot again.
