PARKING ASSIST MONITOR SYSTEM(w/ Side Monitor System), Diagnostic DTC:C1611

DTC Code DTC Name
C1611 ECU Malfunction

DESCRIPTION

This DTC is stored if the parking assist ECU judges that there is an internal malfunction as a result of its self check.

Tech Tips

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

DTC Code DTC Detection Condition Trouble Area
C1611
  • EEPROM Status (Initial read)

  • AISIC Output Status


  • Parking assist ECU initialization (not initialized parking assist ECU)

  • Back camera position setting (initialized parking assist ECU)

  • Side camera position setting (initialized parking assist ECU)

  • Steering Angle setting (initialized parking assist ECU)

  • Parking assist ECU

CAUTION / NOTICE / HINT

Note


  • When "System initializing" is displayed on the parking assist ECU after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the parking assist monitor system may be needed Click here.

PROCEDURE


  1. READ VALUE USING GTS (PARKING ASSIST ECU STATUS)


    1. Use the Data List to check if the parking assist ECU status is functioning properly Click here.

      Parking Assist Monitor System
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      EEPROM Status (Initial read) Parking assist ECU information / OK or NG

      OK: Parking assist ECU is normal

      NG: Parking assist ECU is abnormal

      -
      AISIC 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 malfunctions in parking assist ECU.

  2. SETTINGS (PARKING ASSIST ECU INITIALIZATION)

    Tech Tips


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

    • If the parking assist ECU 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 parking assist ECU was able to properly store the information from initialization Click here.

      Tech Tips

      The procedure to make the parking assist ECU store the vehicle information differs when the parking assist ECU 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 parking assist ECU.

      Condition Procedure
      Not initialized

      Parking assist ECU initialization Click here

      Initialized

  3. CHECK FOR DTC


    1. Clear the DTCs Click here.

    2. Check for DTCs Click here.

      OK
      DTC C1611 is not output.

      Tech Tips


      • If DTC C1611 is output, perform the procedure to allow the parking assist ECU to store the vehicle information again.

      • If DTC C1611 is still output after performing the procedure to make the parking assist ECU store the vehicle information 3 times, replace the parking assist ECU.

      • If DTC C1611 is output frequently, replace the parking assist ECU even though the DTC is not output when rechecking for DTCs.
