      Tech Tips

      
      

      • If the system cannot enter diagnostic mode, inspect the AVC-LAN and all the components that connect to the AVC-LAN for short circuits and repair or replace the malfunctioning part.

      • Even if the symptom malfunction is not confirmed, check the DTCs. This is because the system stores past DTCs.

      • Check and clear past DTCs. Then recheck for DTCs.
