PARKING ASSIST MONITOR SYSTEM(for Camera built-in ECU), Diagnostic DTC:C1611

DTC Code DTC Name
C1611 ECU Malfunction

DESCRIPTION

This DTC is stored if the television camera assembly judges that there is an internal malfunction as a result of its self check.

Tech Tips

The television camera assembly stores different types of information during initialization. If the television camera assembly cannot read the stored information when it is activated, the television camera assembly judges that there is an internal malfunction and stores this DTC.

DTC No. Detection Item DTC Detection Condition Trouble Area

PROCEDURE


  1. READ VALUE USING GTS (TELEVISION CAMERA ASSEMBLY STATUS)


    1. Use the Data List to check if the television camera assembly status is functioning properly.

      Click here


      Chassis > IPA/Parking Assist Monitor > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      EEPROM Status (Initial read) Television camera assembly information OK or NG

      OK: Television camera assembly is normal

      NG: Television camera assembly is abnormal

      		 -
      ASIC Output Status Output condition of camera display signal OK or NG

      OK: Output condition of camera display signal is normal

      NG: Output condition of camera display signal is abnormal

      		 If "NG" is displayed, there is a malfunction in the television camera assembly.

  2. SETTINGS (TELEVISION CAMERA ASSEMBLY INITIALIZATION)

    Tech Tips


    • The television camera assembly stores different types of information during initialization. If the television camera assembly cannot read the stored information when it is activated, the television camera assembly judges that there is an internal malfunction and stores this DTC.

    • If the television camera assembly cannot read the stored information when it is activated, allowing the ECU to store the information again may return the system to normal.


    1. Use the transition of diagnosis screens (note which transition pattern occurs) to confirm if the television camera assembly was able to properly store the information from initialization.

      Tech Tips

      The procedure to make the television camera assembly store the vehicle information differs when the television camera assembly has stored the information (initialized) and when the information has not been stored (not initialized).

    2. Perform the following procedure depending on the memory conditions to register the vehicle information into the television camera assembly.

      Condition Procedure
      Not initialized

  3. CHECK FOR DTC


    1. Clear the DTCs.

      Click here


      Chassis > IPA/Parking Assist Monitor > Clear DTCs

    2. Check for DTCs.

      Click here


      Chassis > IPA/Parking Assist Monitor > Trouble Codes
      Result
      Proceed to
      No DTC is output
      DTC C1611 is output

      Tech Tips


      • If DTC C1611 is output, perform the procedure to allow the television camera assembly to store the vehicle information again.

      • If DTC C1611 is still output after performing the procedure to make the television camera assembly store the vehicle information 3 times, replace the television camera assembly.

      • If DTC C1611 is output frequently, replace the television camera assembly even though the DTC is not output when rechecking for DTCs.


    No DTC is output

    END (SETTINGS ARE DEFECTIVE)
